Why exchanges restrict accounts

1The five families of triggers

Several reasons can apply at once: a verification request may arrive together with a source-of-funds review. Each part is answered on its own terms.

21. KYC and verification

Typical triggers are a mismatch between the data on file and the documents supplied, expired documents, a missing proof of address, and questions about the source of funds attached to the verification request.

Rejections are often technical. In one case of ours, an exchange service stalled a review for a month because some photographs of the documents were of low quality and the information could not be read; from the platform's side this raised extra suspicion and the check was suspended without a clear explanation. Binance's help centre describes its video-verification route in exact detail (ID in frame, the date and your email in the phrase, an unedited photo), and a file that misses one requirement is refused by a checklist.

First step: re-read the exact wording of the request and answer precisely that, with readable files in the requested format.

32. Risk scoring and AML review

Typical triggers are sudden large deposits or withdrawals, chains that pass through wallets marked as high-risk, logins from unusual countries or VPN use, and the aftermath of a trade through an exchange service or a P2P counterparty who did not pay or turned out to be fraudulent.

The exchange is usually not asking you to argue; it is asking for evidence of where the funds came from and what they touched on the way. A single flagged transaction can hold a whole balance: in one of our cases a review of roughly $350,000 centred on a transaction of about 100 USDT. The platform typically does not say which document would satisfy it, because its criteria are confidential.

First step: collect the origin of the specific funds under review, not your whole financial history: deposit addresses, transaction hashes, the trades or transfers that produced the money, and counterparty records where they exist.

43. Terms of Use

Multiple accounts, automated trading where it is not permitted and operating from an unsupported jurisdiction are the classic examples. P2P has its own rules: Binance's published P2P policy names repeated order cancellations as a trigger, and its help centre says what an appeal of a P2P suspension expects, including bank statements, order numbers and payment receipts.

First step: find the exact clause the platform refers to and check the appeal route it publishes for that case. Official appeal routes are free.

54. Regulatory holds and law enforcement

Requests from a regulator, sanctions screening and AML investigations belong here. The usual sign is silence: no substance, no deadline and no route, because the platform may not be free to share more. Binance states that not all account restrictions are open to appeal, including law enforcement and regulatory holds.

One variant looks like this family but may not be. In one of our cases the restriction on a Binance account of about $75,000 turned out to be triggered by a third party's claim that the funds were stolen, with no documents and no case details shared with the client. We advised asking the platform which authority or department the claim came from, so the client could see it and answer formally. Support then suggested that the client transfer about $30,000 to an internal wallet to “settle” the matter. The client declined, the case was escalated through official channels, and the exchange later removed the restrictions.

First step: ask the exchange in writing whether the hold comes from its own assessment or from an external authority, and if external, which one.

65. Account security

A suspected compromise, logins from unknown devices or a recent security change can put a temporary hold on withdrawals while the account keeps working. Binance states that this automatic hold lasts 24–48 hours and cannot be shortened (source).

First step: wait. Inside that window there is usually nothing to appeal.

7The first 24 hours

• Save everything: screenshots of the notice, the full text of every message from support, ticket numbers, dates and times.
• Place your case in one of the five families using the table above.
• Use the exchange's free channel: the in-account appeal, a support ticket or a source-of-funds form. You can ask support for the reason and the list of documents, but avoid sending detailed explanations at random: contradictions in answers already sent can seriously complicate a case.
• Answer exactly what was asked. One complete reply is better than several partial ones.
• Get help if the answer is not covered by that flow: a refused first answer, an unexplained repeat request, or a chain of funds that is hard to document.

8If you want a second pair of eyes

The first consultation is free: send us the messages you received from the exchange and we will tell you what we see. We do not guarantee unblocking; the decision is the exchange's. Related pages: how it works, how long a case takes, frequently asked questions.
