What to Do If Binance KYC Says Identity Already Linked to Another Account

14 min read 2026-03-30 KYC Verification

While completing Binance KYC verification, you encounter a message saying "This identity information is already linked to another account" or something similar, and the submission fails. This issue can be frustrating, but it is not unsolvable. Below, we analyze the various causes and their corresponding solutions. Check your verification page on the Binance official website or the Binance official app for the exact error message. Apple users can refer to the iOS installation guide.

Why This Message Appears

You Previously Registered Another Account

This is the most common cause. You may have registered a Binance account previously using a different email or phone number and already completed KYC with the same identity document. Binance's rule is that one identity can only be verified on one account, so attempting to verify a second account with the same document will be rejected.

Think back:

  • Did you register with a different email before?
  • Did you create an account with a phone number?
  • Could you have registered long ago and forgotten about it?

Someone Else Used Your Identity Information

In some cases, someone may have stolen your identity to register a Binance account and complete verification. While uncommon, it does happen.

Binance Merged Duplicate Accounts

Binance automatically detects duplicate registration behavior. If the system finds multiple accounts attempting to verify with the same identity, it may restrict subsequent verification requests.

A Failed Verification Left a Record

In some cases, even if a previous verification attempt did not pass, the identity information may have already been recorded in the system.

Solutions for Different Scenarios

Scenario 1: You Do Have Another Old Account

If you confirm that you previously registered another account:

Recover the old account:

  1. Try to recall the email or phone number you used before
  2. Log in with that email or phone number
  3. If you forgot the password, use the "Forgot Password" feature to reset it
  4. If you cannot remember the email either, contact support and provide your identity information

Continue using the old account:

If the old account is already verified, the simplest solution is to continue using it and abandon the new one.

Delete the old account, then verify the new one:

If you truly want to use the new account:

  1. First recover the old account
  2. Contact support to request account deletion
  3. Wait for the old account to be fully deleted (identity information released)
  4. Then verify the new account with KYC

Note: Make sure the old account has no remaining assets before deletion — this action is irreversible.

Scenario 2: You Do Not Remember Having an Old Account

If you have no recollection of registering another account:

  1. Contact support:

    • Reach out via live chat and explain the situation
    • Provide your identity document details
    • Ask support to check if another account is using your identity
    • They will share partial information about that account (e.g., the first and last few characters of the email)

  2. Confirm whether it is yours:

    • If the partial information looks familiar, it is likely your old account
    • Try to recover it

Scenario 3: You Suspect Identity Theft

If you are certain you have never registered on Binance but the system shows your identity is already in use:

  1. Contact Binance support immediately:

    • Explain that you suspect identity theft
    • Provide photos of your identity document
    • You may need to undergo additional identity verification

  2. File an appeal:

    • Submit a ticket through the Help Center
    • Title it clearly, e.g., "Identity information used without authorization"
    • Describe the situation in detail
    • Attach photos of your ID and a selfie holding the document

  3. Wait for resolution:

    • These cases require manual investigation
    • Processing may take several days to weeks
    • Binance will investigate and take appropriate action

  4. File a police report:

    • If identity theft is confirmed, consider filing a report with your local law enforcement
    • Keep the police report — Binance may request it

Scenario 4: A Friend or Family Member Used Your Documents

Someone you know may have registered and verified an account using your identity:

  • Confirm with anyone who might have used your information
  • If confirmed, work out a resolution (delete that account or use it yourself)
  • In the future, never let others use your identity documents

How to Contact Support Properly

Resolving account-linking issues usually requires human support:

Live Chat

  1. Open the Binance app or website
  2. Find the "Help" or support icon
  3. Start by describing your issue to the chatbot
  4. Type "human agent" to connect with a live representative
  5. Clearly describe your problem
  6. Provide the necessary identity information

Submit a Ticket

  1. Go to the Binance Help Center
  2. Select "Submit a Ticket"
  3. Choose the "Identity Verification" category
  4. Describe the issue in detail
  5. Upload supporting evidence

What to Prepare

Before contacting support, have the following ready:

  • The email or phone number used to register your current account
  • Photos of your identity document (front and back)
  • A selfie holding your ID
  • A detailed description of the issue
  • Any information about the old account, if available

Preventive Measures

To avoid similar issues in the future:

One Person, One Account

Binance's rule is one verified account per person. Decide which email and phone number to use before registering, and do not create multiple accounts.

Protect Your Identity Information

  • Do not share photos of your ID casually
  • Do not let others register exchange accounts on your behalf
  • Mark copies of your ID with the purpose and date
  • Be mindful of personal information security

Keep Your Account Details Recorded

Store your Binance account credentials, registration email, and phone number in a secure place so you do not forget and end up registering a new account.

Security Reminders

When dealing with account-linking issues, be cautious:

  • Only handle this through official support channels on the Binance official website
  • Do not trust third-party services claiming to "unlink" your account
  • Support will never proactively contact you or ask for your password or verification codes
  • Identity information submitted during the process is securely stored by Binance
  • Do not publicly discuss your account issue details on social media

While account-linking issues can be tedious to resolve, Binance support can generally help. The key is to provide accurate information and wait patiently. If you have not installed the app yet, download the Binance official app to contact the in-app support team for faster response times.
