Why a Manual Review Flag Can Hold Your Withdrawal for Days Without Notice

04 November 2026

A manual review flag is a hold placed on a withdrawal by an exchange’s compliance or risk team, usually triggered by automated rules that detect something unusual. When this happens, your withdrawal can sit in a “pending” or “processing” state for days - sometimes without any visible error message or update in your account interface. The only way to unblock it is to contact support and provide the specific documentation they request.

What triggers a manual review flag

Exchanges use automated systems to screen every withdrawal request. Most passes through in seconds. A manual review flag is raised when the automated system cannot confidently clear the transaction. Common triggers include:

• Large or unusual withdrawal amounts relative to your account history. What counts as “large” varies by exchange and your typical activity.
• Withdrawal to an address that has no prior transaction history with the exchange, or one that appears on a watchlist.
• A pattern that mimics layering - for example, multiple small deposits followed by a single large withdrawal.
• A mismatch between your registered location and the IP address used to request the withdrawal.
• Recent changes to your account, such as a new device, new phone number, or updated KYC documents.

What actually happens inside the exchange

Once the flag is raised, the withdrawal enters a queue that human reviewers work through. Here is what usually occurs:

1. The withdrawal status changes from “processing” to “pending” or “under review.” On some exchanges, it may appear as “complete” on your side but never reach the blockchain.
2. No notification is sent. Many exchanges do not inform you that a manual review is in progress. They may consider it a security measure to avoid tipping off a potential attacker.
3. The reviewer looks at your account history, transaction patterns, and any notes from previous reviews. They may also check the destination address against external databases.
4. If the reviewer needs more information, they will put the withdrawal on hold and mark it for a follow-up. They may or may not send you an email requesting documents.
5. The review can take anywhere from a few hours to several days, depending on the exchange’s staffing, the complexity of the case, and whether you respond promptly.

How to actually unblock it

Waiting passively rarely works. The steps that consistently resolve a manual review hold are:

1. Check your email and spam folder for any message from the exchange. Look for a subject line like “Withdrawal Review” or “Action Required.”
2. Open a support ticket directly, referencing the withdrawal transaction ID. Do not start a new withdrawal - this can confuse the system.
3. Provide clear documentation when asked. This typically includes:
4. A government-issued photo ID.
5. A selfie holding the ID.
6. A source-of-funds explanation, such as a recent payslip, tax return, or bank statement showing the deposit.
7. Proof of address if the withdrawal amount is very large.
8. Be prepared to answer questions about why you are sending to that address, where the funds came from, and whether the withdrawal is for your own account.
9. If you get no response for 48 hours, escalate by requesting a supervisor or compliance officer. Many exchanges have a separate compliance email address not listed in the main support page.

What does not help

• Cancelling and re-submitting the withdrawal often re-triggers the same flag. You will be stuck in the same queue.
• Sending multiple support tickets about the same withdrawal can slow things down, because each ticket may be assigned to a different reviewer.
• Posting on social media rarely speeds up a manual review. Exchanges treat these requests through internal processes, not public pressure.

Why it can take days without notice

Manual review is a human process, not an automated one. The exchange’s compliance team may be understaffed, handling many cases, or waiting for additional information from a third party (such as a bank or law enforcement request). Because the system does not expose this internal workflow to you, the withdrawal simply appears stuck. The exchange’s priority is to prevent fraud and money laundering, not to communicate every step of the review.

If the withdrawal remains in this state for more than five business days without any communication, the most likely explanation is that your case requires deeper investigation, or that your support request was not properly routed.
