Why You Need to Fill in the Source When Depositing from Other Exchanges to Binance
Binance asks you to fill in fund source information during deposits fundamentally because of compliance requirements. This is mainly to collect necessary information to comply with global Anti-Money Laundering (AML) and Counter-Terrorism Financing (CTF) regulations, not because the platform is trying to make things difficult.

This requirement mainly appears in two places, and the rules are somewhat different: one is the globally applicable Travel Rule, which targets on-chain cryptocurrency transfers; the other is source of funds verification for specific fiat deposits.
Prerequisite: Understanding the Differences in Requirements for Different Types of Deposits
To understand why you are asked to fill this out, you need to first see which deposit method you are using, as the corresponding rules are completely different:
On-chain Deposit (Cryptocurrency Transfer): This is to comply with the Travel Rule. When you deposit from another exchange to Binance, the system will ask you to complete a short questionnaire providing the recipient's relevant information, such as their name. This rule requires Virtual Asset Service Providers (VASPs) to collect and verify the identities and wallet information of both parties when a transfer exceeds a certain threshold.
Fiat Deposit (Bank Transfer): This requirement appears in the compliant Source of Funds (SoF) verification process. The platform needs to understand the specific source of the fiat currency you are using to purchase cryptocurrency (for example, salary income, investment returns, or other sources).
Step 1: Understand the Travel Rule Questionnaire
What to do: When you are making an on-chain deposit, the system will pop up a questionnaire where you need to fill in the recipient's information.
How to do it:
On the withdrawal page, the system will ask you to provide the recipient's full name, country/region of residence, and the name of the receiving exchange, or declare that the recipient is a private wallet.
This is to ensure transparency of fund flows, thereby combating money laundering and terrorist financing.
What counts as done: You accurately fill in the required recipient information and successfully submit the questionnaire.
Step 2: Handle Source of Funds (SoF) Verification for Fiat Deposits
What to do: If you make a fiat deposit, the platform may require you to prove the source of the funds.
How to do it:
Binance needs to understand the source of the specific fiat or cryptocurrency you are depositing, in order to assess account risk and ensure compliance.
This may involve providing some documents, such as:
Employment Income: Pay stubs or bank statements from the last 3 months.
Investment Income: Screenshots of transactions or holdings from cryptocurrency accounts.
Other Sources: Such as a contract for selling real estate, proof of inheritance or gift, etc.
What counts as done: You understand the types of supporting documents that may be required and can submit them according to the platform's request.
Step 3: Ensure Information is Accurate and Consistent
What to do: Regardless of which form you fill out, information consistency is important.
How to do it:
When filling out the Travel Rule questionnaire or source of funds information, ensure the information provided is accurate and complete.
This information will be used for internal compliance review; inconsistent information may cause deposit delays or rejection.
What counts as done: You are prepared to truthfully fill in all information, avoiding deposit failure due to incorrect details.
Common Reasons for Failure
Missing or Incorrect Information: Not correctly filling in a reference code will cause fiat deposit failure. Similarly, incorrect information on the Travel Rule questionnaire may also delay the transaction.
Inability to Prove Source of Funds: When the platform requires SoF verification, if you are unable to submit supporting documents that meet the standards (such as recent, clear, unedited PDF files), the review may not pass.
Using Someone Else's Account: When making a fiat deposit (e.g., via SWIFT or SEPA transfer), the name of the bank account holder must match the name on your Binance account, otherwise the deposit will be rejected.
Risk Reminder
To meet the Travel Rule and anti-money laundering compliance requirements, Binance needs to collect this information. Providing inaccurate or false information may result in rejected transactions or even restricted account permissions.

How to Confirm You Have Correctly Understood
Now you should understand that Binance requiring source information is not about collecting privacy, but about complying with global regulatory standards.
Next time you deposit cryptocurrency from another exchange to Binance, you can prepare the recipient's information (name, etc.) in advance to smoothly fill out the Travel Rule questionnaire.
If making a fiat deposit, you can first check the specific source of funds requirements on the [Assets] - [Fiat Orders] page and prepare the relevant supporting documents in advance. This will help you avoid a last-minute scramble when submitting.
