How to Verify Someone Really Works for a Company: 13 Checks
Scammers can copy a name, a logo and a job title in a minute. A few checks you can run yourself show whether a βsupport agentβ, recruiter or business partner isΒ real.
A message lands on Telegram: βHi, Iβm Daniel from the security team at your exchange. We saw a login from a new device. Please confirm your wallet so we can protect your funds.β The profile photo shows the company logo. The English is good. Daniel is patient, and he knows your username.
Daniel does not work at the exchange. He works for a scam crew, and the βconfirm your walletβ link empties yourΒ wallet.
People reported losing $3.5 billion to imposter scams in 2025, and nearly $1 billion of that went to people pretending to be a business, according to the FTCβs June 2026 report. The FBIβs figure for crypto is bigger. Victims told its Internet Crime Complaint Center they lost $11.4 billion to crypto-related crime in 2025, more than half of all the losses it counted that year (IC3 2025Β report).
A lot of those losses started the same way. Someone claimed to work for a company, and the victim took their word for it. Some victims did not know how to check. Others saw a familiar name, a logo and a confident tone, and felt noΒ need.
The checks run from a 30-second test to reading the hidden part of an email. If you only have time for two, use the first and the tenth: both are free, and both are very hard for a scammer toΒ fake.

The one rule behind everyΒ check
Never use the contact details a stranger gives you to check that stranger.
If βDanielβ sends you a phone number, a website or an email address and says βcontact us here to confirmβ, all three belong to Daniel. Calling the number he gave you only proves that Daniel answers his ownΒ phone.
Every check in this list works the same way. You find the companyβs official channel yourself, from a source the stranger did not hand you. Then you ask that channel whether the person isΒ real.
Why people skip theΒ check
It looks official, so we assume it is. A logo, a job title and a company name take a minute to copy. Real staff photos sit on LinkedIn and on company βTeamβ pages for anyone to download.
They already know something about us. Your username, your last order or the exchange you use is often public, or leaked in a data breach. Knowing those details says nothing about who the senderΒ is.
There is a clock. βYour account will be frozen in 30 minutes.β The deadline is there to stop you checking. A real company will still exist after you spend ten minutes confirming.
The more urgent the message, the slower you shouldΒ move.
13 ways to check that someone works for aΒ company
1. Contact the company yourself, through its officialΒ website
Type the companyβs address into your browser by hand, or use a bookmark you saved earlier. Skip links in the message and skip search ads, because scammers buy ads for fake support pages. Find the support page or contact form and ask: βSomeone called Daniel, Telegram @daniel_sec_team, says he works on your security team and contacted me today. Is thatΒ real?β
Example. A βrecruiterβ emails about a job at a well-known firm. You open the firmβs careers page from a bookmark. The role is not listed, and the HR address on the page is another one. The recruiter does not work for theΒ firm.
The catch is speed. If support takes two days to reply, wait two days, and do nothing the stranger asks in the meantime.
2. Use the companyβs own checkingΒ tool
Many crypto exchanges now run a page where you paste a username, email, phone number or link, and it tells you whether the contact is official. Three examples:
- Binance Verify at binance.com/en/official-verification checks domains, email addresses, phone numbers and social handles, Telegram included. Binance says anyone who claims to work with Binance and cannot be confirmed there should be treated as untrusted.
- OKX has a channel verification page in its Help Center. OKX says to type the β@β before a username, or the result can beΒ wrong.
- KuCoin runs an Official Verification Center at kucoin.com/cert. It checks emails, Telegram IDs, X accounts, websites and official wallet addresses.
Example. βBinance supportβ adds you on Telegram as @BinanceSupportDesk. You paste the handle into Binance Verify, and it comes back as not official. Block the account and reportΒ it.
Reach these tools by typing the exchangeβs main address yourself and looking in its Help Center for βverifyβ or βofficial channelβ. If the stranger sends you a link to a βchecking toolβ, that link is theΒ trap.
A tool can confirm that an address belongs to the company. It cannot confirm that an email really came from that address, because the From line can be forged. Bybitβs own help page warns about this. For email, add checkΒ 5.
3. Ask them to message you from the companyβs official XΒ account
Ask the person to prove it on a channel only the company controls. Better still, contact that channel yourself. Here is a message you canΒ send:
βBefore I continue, please send me a DM from @ExampleExchange, the official account, confirming you work there and what this is about. Or I can DM that account andΒ ask.β
A real employee will say βsureβ or send you to the official support channel. A scammer will make excuses: βThat account is for marketing onlyβ, βour team canβt access itβ, βthis is confidential.β Each of those excuses means the person cannot proveΒ it.
Make sure you have the right official account. Open it from a link on the companyβs own website, since search results can show copycat accounts. It should have years of posts and the follower count you wouldΒ expect.
Then look for Xβs affiliate badge. Companies that pay X to verify their brand can link their staff accounts. An affiliated employee shows a small copy of the companyβs profile picture next to their name, and tapping it opens the companyβs account. A plain blue tick on a personal account says nothing about employment, because anyone can buyΒ one.
Official accounts do get hacked. If the official account suddenly DMs you first with a link, treat that as suspicious too. Most companies never start private conversations about yourΒ account.
4. Ask for an email from the company domain, then read that domain letter byΒ letter
A real employee can email you from a work address in a minute. Ask for it. A recruiter or βpartnerβ who only uses Gmail, Outlook.com, Telegram or WhatsApp fails thisΒ test.
Then read the address slowly. Say the real company is Example Exchange at example.com. Each of these addresses isΒ fake:
- support@examp1e.com (the digit 1 in place of the letterΒ l)
- hr@exarnple.com ("rn" looks like "m" in manyΒ fonts)
- security@example-support.com (an extra word added to theΒ name)
- team@example.co (the wrongΒ ending)
- alerts@example.com.account-check.net (the real domain is account-check.net, read from theΒ right)
- help@exΠ°mple.com (the "Π°" is a Cyrillic letter that looks the same as the LatinΒ one)
Two more things to check in the sameΒ email:
- The display name can say anything. βExample Exchange Securityβ might sit on top of x7k2@mail-ru.biz. Click or tap the name to see the realΒ address.
- The Reply-To can differ. An email can arrive from an address that looks right and still send your reply to a stranger. Hit reply and look at the βToβ field before youΒ type.
A correct domain is a good start. On its own it can still be forged, which is why check 5 comesΒ next.
5. Check the emailβs sign-in results (SPF, DKIM andΒ DMARC)
Every email carries test results that show whether it really came from the domain in the From line. Your inbox runs these tests already. You just have toΒ look.
In Gmail, open the email, click the three dots and choose βShow originalβ. In Outlook, open the message, then More actions, View, βView message sourceβ. In Apple Mail, choose View, Message, RawΒ Source.
Find the line that starts with Authentication-Results. A real email from example.com looks likeΒ this:
dkim=pass header.d=example.com; spf=pass smtp.mailfrom=example.com; dmarc=pass header.from=example.com
In plainΒ words:
- SPF pass means the server that sent the email is on the domainβs approvedΒ list.
- DKIM pass means the email carries the domainβs digital signature, and nobody changed the message on theΒ way.
- DMARC pass means at least one of those two tests passed for the same domain you see in the From line. This is the result to readΒ first.

Warning signs: dmarc=fail, spf=fail, dkim=none, or a pass for some other domain, such as dkim=pass header.d=bulk-mailer-7.net on an email that claims to be from example.com.
Example. An email from βsecurity@example.comβ asks you to reset your password. Gmailβs βShow originalβ says dmarc=fail header.from=example.com. The From line is forged. Delete theΒ email.
A DMARC pass means the email left a mail system the company approved. A hacked staff mailbox passes too, and forwarded emails sometimes fail SPF while being genuine. Treat the result as strong evidence and combine it with the otherΒ checks.
6. Paste the raw email into an AI chatbot and ask it to find theΒ tricks
Raw email source is hard to read. A chatbot such as ChatGPT, Claude or Gemini can read it for you and point at the parts that lookΒ wrong.
- Open βShow originalβ (or βView message sourceβ) as in check 5 and copy everything.
- Remove your own details first: your email address, name, phone number, account numbers and any codes. Replace each with β[removed]β.
- Paste the text into the chatbot with a prompt like thisΒ one.
βBelow is the raw source of an email, including headers and HTML. I think it may be a phishing email pretending to be from example.com. Please check: (1) Do SPF, DKIM and DMARC pass, and for which domain? (2) Does the From address match the Return-Path and Reply-To? (3) List every link in the HTML and show where it really points, compared with the text shown to me. (4) Are any domains lookalikes of example.com? (5) Anything else suspicious? Quote the exact lines you relyΒ on.β
AI is good at this job. It will catch a link whose visible text says https://example.com/login while the code behind it points to https://example-com.login-verify.app, and it spots lookalike domains and hidden text far faster than most peopleΒ do.
Example. You paste a βyour withdrawal is on holdβ email. The chatbot lists four links. Three go to example.com. The βRelease fundsβ button goes to a domain nobody at the company owns, and that button is theΒ scam.
Chatbots also make mistakes in both directions. An email that βlooks fineβ to a chatbot can still come from a hacked real account. Make it quote the lines it relies on, then check those lines yourself. Never paste passwords, seed phrases or one-time codes into anyΒ chatbot.
7. Hover over links and check when the domain was registered
Before you click anything, hover over the link on a computer, or press and hold it on a phone, to see the real address. Read the domain from the right, as in checkΒ 4.
Then look up when the domain was created. Paste it into the ICANN lookup and check the βCreatedβ date. A company that has existed for ten years does not send security alerts from a domain registered lastΒ Tuesday.
Example. A βpartnership managerβ from a known crypto project emails from bd@exampleprotocol-team.com. ICANN lookup shows the domain was created nine days ago. The project's real site has used a different domain sinceΒ 2021.
A brand-new domain is a strong warning sign. An old domain proves less, because some scam domains sit unused for months before they areΒ used.
8. Check their LinkedIn the rightΒ way
A LinkedIn profile is easy to fake. A good fake still leaves gaps you canΒ spot.
- Look for LinkedInβs workplace check. LinkedIn lets members confirm their current employer, most often with a code sent to their work email, and the result shows on the profile. It confirms the company only. The job title is unchecked, and only some companies support it soΒ far.
- Start from the company page. Open the companyβs official LinkedIn page, go to its People tab and search for the name. Searching from the company side is harder to fool than clicking a profile someone sentΒ you.
- Read the history. Real profiles usually have years of posts, a work history that makes sense, and connections who also work at the company. Fake ones are often new, with a few hundred random connections and a headshot that looks tooΒ perfect.
- Message the profile directly. Ask the LinkedIn account to confirm the chat you are having on Telegram or WhatsApp. Scammers often copy a real employeeβs profile, and the real employee will reply confused.
A long history plus a workplace check is good evidence that the person exists and works there. It does not show that the person messaging you on another app is the same person, so always confirm on the profileΒ itself.
9. Check the companyβs team page, docs, GitHub and community adminΒ lists
Many companies publish who speaks forΒ them:
- The Team or About page on the officialΒ website.
- The docs or Help Center, which often list official support channels and say βwe will never DM youΒ first.β
- The GitHub organization. Open github.com/the-company and look at public members. A developer who says they work there can usually be found in thatΒ list.
- Telegram and Discord admin lists. Check the adminβs username, the part with the @, and ignore the display name. Anyone can set a display name to βExample Support | Adminβ. OKX advises copying the username from the profile screen. If the βusernameβ appears only in the bio, the account is probablyΒ fake.
Example. You post a question in a projectβs Discord, and βMod Alexβ sends you a private message offering help. You check the serverβs member list. The real Alex has a staff role and a different username. The account in your DMs joined the server yesterday.
Lists go stale when people leave, so when the stakes are high, confirm with check 1 asΒ well.
10. Call back through the switchboard
If someone phones you from βthe companyβ, hang up and call the number on the companyβs website or on the back of your card. Ask to be put through to that person or department.
Example. βYour bankβs fraud teamβ calls and asks you to move savings to a βsafe accountβ. You hang up and dial the number printed on your bank card. The bank has no record of the call. The FTC says bank impersonators caused the largest reported losses among business imposters in 2025, and these scams often end with victims persuaded to move money to βprotectβ it.
This check is hard to beat. Use another phone if you can, because some scams keep the line open after you hangΒ up.
11. For crypto: ask for a signed message from a knownΒ wallet
Crypto has a check that nobody can fake without the private key. If a project or team member claims to control a wallet the project lists publicly, ask them to sign a message withΒ it.
- Find the wallet address yourself, in the projectβs official docs, website or official XΒ account.
- Ask them to sign a message with todayβs date and your name in it, such as: βI am Daniel from Example Protocol. Signed for Priya on 29 October 2026.β The date and your name stop them from reusing an old signature.
- Check the signature on Etherscanβs Verified Signatures page. BaseScan, Arbiscan and other Ethereum-style explorers have the same tool. Enter the address, the message and the signature, and see whether it isΒ valid.
A valid signature proves the signer controls that wallet. Whether the wallet belongs to the project depends on where you found the address, which is why step 1Β matters.
12. Donβt treat a video call asΒ proof
Plenty of people still treat a video call as the final word. Since 2024 that has been a costly habit. In January 2024, a finance employee at the Hong Kong office of engineering firm Arup joined a video call with what looked like the companyβs CFO and other colleagues. Every other face on the call was a deepfake. The employee made 15 transfers worth HK$200 million, about $25.6 million, before checking with the head office, Hong Kong police said. Arup later confirmed to CNN that fake voices and images wereΒ used.
If a video call is part of the story, confirm through a second channel you found yourself: the company switchboard, the official X account or a work email you already confirmed with checks 4 and 5. Ask for a calendar invite sent from the company domain, and run check 5 onΒ it.
13. Search their name, handle and domain withΒ βscamβ
Spend a minute on a webΒ search:
- "@daniel_sec_team" scam
- "example-support.com"
- "Example Exchange" recruiter scam
Also look for the companyβs own warnings. Many companies publish lists of fake domains and copycat tricks on their blog or HelpΒ Center.
If others have reported the same handle or domain, you know it is a scam within a minute. An empty search proves nothing, because a new scam has no reportsΒ yet.
Requests that end the conversation, whoever isΒ asking
Some requests are scams however well the person passes these 13 checks, because a hacked real account can pass every test. Nothing makes these requestsΒ safe:
- Your seed phrase, recovery phrase or private key. No company ever needs it. Anyone who asks is stealing.
- Your password or a one-time code from SMS, email or an authenticator app.
- Remote access or screen sharing through AnyDesk, TeamViewer or a βsupportΒ toolβ.
- Moving money to a βsafeβ or βsecureβ wallet or account to protectΒ it.
- Paying to receive money, such as a fee to unlock a withdrawal, a deposit to start a job, or βgasβ to claim aΒ prize.
- Installing software for a job interview. Fake crypto recruiters ask candidates to install a βvideo call appβ or run a coding test that carriesΒ malware.
- Connecting your wallet to βverifyβ it, or signing a transaction you do not understand.
When you see one of these, stop. You donβt owe anyone a politeΒ goodbye.
Three common scams, checked step byΒ step
Scam 1: Fake exchange support onΒ Telegram
The message. β@ExampleEx_Supportβ writes: βYour withdrawal is stuck. Connect your wallet at example-unlock.com to releaseΒ it.β
The checks.
- Check 2: the exchangeβs checking tool says the handle is not official.
- Check 7: ICANN lookup shows example-unlock.com was created thisΒ month.
- The requests list: βconnect your wallet to release fundsβ is onΒ it.
Verdict. Scam. Block the account and report it to the exchange and to Telegram.
Scam 2: A recruiter from a cryptoΒ firm
The message. A LinkedIn profile titled βSenior Talent Partner at Example Labsβ offers $180,000 for a remote developer role. The next step is a βtechnical testβ: download a code repository and run it on yourΒ laptop.
The checks.
- Check 4: you ask for an email from @examplelabs.com. The reply comes from a Gmail account, βbecause of internalΒ policyβ.
- Check 8: nobody with that name appears on Example Labsβ LinkedIn People tab, and the profile is four monthsΒ old.
- Check 1: Example Labsβ careers page lists no suchΒ role.
- The requests list: running unknown code from a stranger is onΒ it.
Verdict. Scam. If you already ran the code, treat the laptop as compromised. Move any crypto to a new wallet created on a clean device, and change your passwords from thatΒ device.
Scam 3: A βpartnershipβ email to a smallΒ project
The message. βHi, I lead business development at Example Exchange. Weβd like to list your token. Please sign the attached agreement and pay the $15,000 listing deposit.β
The checks.
- Check 5: βShow originalβ says dmarc=pass header.from=example-exchange-listing.com. The email really came from that domain, and that domain belongs to someoneΒ else.
- Check 3: you DM the exchangeβs official X account. The exchange replies that it never asks for listing deposits by email and does not know thisΒ person.
- Check 2: the exchangeβs checking tool does not recognize theΒ address.
Verdict. Scam. The email passed DMARC for its own lookalike domain, which is why reading the domain letter by letter (check 4) comes before the headerΒ check.
A checklist you canΒ save
Before you share anything, pay anything or click anything:
- I found the companyβs contact details myself. This person did not give them toΒ me.
- I asked the company, through that channel, whether this person isΒ real.
- I checked the handle or email in the companyβs checking tool, if it hasΒ one.
- I read the email domain letter by letter, from theΒ right.
- βShow originalβ shows dmarc=pass for the company's realΒ domain.
- I checked where every link really goes, by hovering or withΒ AI.
- The domain is more than a few monthsΒ old.
- Their LinkedIn, team page or GitHub matches, and I searched from the companyβs side.
- Nobody asked for a seed phrase, code, password, remote access, a fee or a softwareΒ install.
- I am not rushing because someone told meΒ to.
If any line fails, stop and confirm through a channel you found yourself.
If you already replied orΒ paid
Act in thisΒ order:
- Stop all contact. Do not send βone lastβ payment to unlock the first one. Fake βrecoveryβ offers usually follow, often from the sameΒ crew.
- Secure your accounts from a device you trust. Change passwords, reset two-factor authentication and log out of other sessions.
- Move your crypto to a new wallet with a new seed phrase if you shared the old phrase or connected your wallet to a site. Revoke token approvals you do not recognize.
- Tell the real company through its official support. The company can freeze accounts and warn otherΒ users.
- Report it. In the US, use reportfraud.ftc.gov and the FBIβs ic3.gov. In the UK, use Report Fraud. Elsewhere, contact your national police cyber-crime unit.
FAQ
How can I verify if someone works for aΒ company?
Contact the company through a channel you found yourself, such as its official website or official X account, and ask whether the person works there. Back that up with the companyβs checking tool if it has one, a work email from the real domain that passes DMARC, and LinkedInβs workplace check.
Can a verified X account beΒ fake?
Yes. Anyone can buy a blue checkmark, and it says nothing about employment. On X, staff linked to a verified company show an affiliate badge, a small copy of the companyβs logo next to their name. Official accounts can still be hacked, so pair the badge with a secondΒ check.
Is an email from the companyβs domain alwaysΒ safe?
No. The From address can be forged, which is why you check for dmarc=pass in the raw headers. A real staff mailbox can also be hacked, and a hacked mailbox passes every check. If the email asks for anything on the requests list, treat it as a scam even when the headersΒ pass.
Can AI tell me if an email is aΒ scam?
AI is very good at reading raw email source and finding fake links, lookalike domains and failed SPF, DKIM or DMARC results. It still makes mistakes. Use it to point at the suspicious lines, check those lines yourself, and remove your personal details before youΒ paste.
Will a real company ever message me first on Telegram or WhatsApp?
Most large crypto exchanges say their staff will not start private chats about your account and will never ask for funds, passwords or codes. Check the companyβs Help Center for its own policy, and treat any unprompted private message as unconfirmed until you checkΒ it.
What is the safest way to check a recruiter?
Ask for an email from the company domain, find the role on the companyβs own careers page, and search the recruiterβs name on the companyβs LinkedIn People tab. Never pay a fee, buy equipment through the recruiter, or install software as part of an interview.
What should I do if someone fails theseΒ checks?
Stop replying, block the account, and report it to the real company and to the platform where you met. If you shared anything or sent money, follow the steps under βIf you already replied orΒ paidβ.
Gaurav Agarwal writes about crypto security and on-chain investigations. If a scam message reached you that these checks did not cover, describe it in the comments, without personal details, and I will add a check forΒ it.
