What to Prepare When Re-submitting After Binance Shows a 'Duplicate Information' System Prompt
First, identify the situation before deciding what to prepare for re-submission. "Duplicate information" means your ID document number has already been used to verify another Binance account. If it's your own old account, you don't need to prepare new materials—just recover the old account. If your ID has been used fraudulently, you'll need to prepare an ID holding declaration video for re-submission. Follow the steps below based on your situation.

Prerequisite: Confirm the Full Content of the System Prompt
Log into your Binance account, go to the [Identity Verification] page, and check the specific prompt displayed by the system.
One of the rejection reasons in Binance's KYC system reads: This ID number has been used. Log in to your original account to complete the transaction.
How to know you've completed this step: Confirm whether the error message contains keywords like "has been used," "duplicate," or "already registered."
Step 1: Determine ID Ownership—Your Own Old Account or Fraudulent Use
Scenario A – You previously verified another Binance account with the same ID:
Try to recover login access to your old account using your phone number or email
If the old account can still be logged into, no re-submission of any materials is needed—simply continue using the old account
If the old account cannot be accessed or you want to close it, you must resolve the old account issue first before submitting verification for the new account
Scenario B – You are certain you've never registered on Binance with this ID: This means your ID information may have been stolen and used for registration. In this case, you need to appeal to customer support and prepare additional declaration materials for re-submission.
How to know you've completed this step: You've confirmed the ID ownership situation and chosen the corresponding resolution path.
Step 2: Recover the Old Account (Solution for Scenario A)
If the ID was used by you for a previous registration, Binance's official guidance is clear: one ID can only verify one account, and you cannot simply "re-submit" on a new account to bypass this restriction.
On the Binance login page, click [Forgot Password] and recover your old account via phone number or email
Once logged into the old account, if it has already passed verification, just use it directly
If the old account is no longer in use, you can apply for a "KYC reset" through customer support—enter "How to update Identity Verification" in the Help Center, and click the "Click here to reset KYC" link in the customer support reply
How to know you've completed this step: The old account has been recovered or a reset request has been submitted.
Step 3: Materials to Prepare for Re-submission When Your ID Has Been Fraudulently Used (Scenario B)
If your ID has indeed been used by someone else without authorization, in addition to the standard ID photos, you'll need to prepare the following extra materials for re-submission:
Materials Checklist:
Clear photos of the front and back of your original ID card (clear, no glare, all four corners visible)
Declaration video (this is the core material—without this video, your appeal will not be accepted)
Declaration Video Recording Requirements (source: Binance Official FAQ):
Hold the ID information page and ensure it appears in the video
Clearly speak the following sentence: "Today is [Month] [Day], [Year]. I, [Full Name], am applying to verify my Binance account, and my linked email/phone number is [xxxx]."
The video must be clear (not blurry, with clear audio)
No screen recording software, no video editing, and no watermarks are allowed
How to know you've completed this step: The declaration video has been recorded and its content is complete and ready for submission.
Step 4: Contact Customer Support to Submit Materials
Go to the [Help Center] on the Binance App or website and click [Contact Support]
Select issues related to [Identity Verification] and initiate a conversation
Explain your situation to customer support: your ID has been fraudulently used for registration, and the system shows a "duplicate information" prompt
Follow the support agent's instructions to submit the following materials:
Photos of the front and back of your ID card
The declaration video recorded in Step 3
A screenshot of the "duplicate information" system prompt
How to know you've completed this step: All materials have been submitted through the customer support channel and the appeal has been accepted.
Step 5: Wait for Customer Support to Process
Once accepted, customer support will freeze or unbind the account fraudulently registered with your ID. Processing time is typically 1–3 business days, and the result will be notified via your registered email and in-app notification.
How to know you've completed this step: You've received a confirmation reply from customer support that the process is complete.
Common Reasons for Failure
Declaration video does not meet requirements: Not holding the ID, failing to recite the full declaration, or blurry video. Carefully review Binance's official requirements before recording.
Directly re-submitting on the new account page: "Duplicate information" is not a photo quality issue. Repeatedly uploading the same material will not change the outcome—the system will block it directly rather than re-review it.

Risk Reminders
One ID can only verify one Binance account. Binance detects duplicate accounts through comprehensive KYC checks, and violations may result in account freezing.
Transferring accounts or using someone else's ID is a violation. Binance explicitly prohibits selling or transferring accounts to others.
Customer support will never ask for an "unbinding fee". Anyone claiming payment is required to unlock an ID or unbind an account is attempting fraud.
Once you've confirmed the ID ownership situation, if it's "your own old account," follow the "Reset KYC" link to resolve it, and refer to the relevant guide for more details. If it's a case of "fraudulent use," follow the steps above to record a declaration video and submit it through customer support. After submission, keep an eye on your email and in-app notifications—processing is typically completed within 1–3 business days.
