KuCoin blocked your account or funds — what to do
After its 2024 DOJ settlement KuCoin tightened KYC/AML sharply: legacy accounts without full verification get restricted, deposits with a risky trail get frozen, and withdrawals go into "security review." Most cases are procedural but require proper documentation.
Why accounts get frozen
Legacy account without KYC
Accounts created before mandatory verification are restricted until full KYC.
Deposit AML screening
An incoming transfer with a high-risk trail: the standard freeze pending explanation.
Jurisdiction restrictions
KuCoin has exited several jurisdictions; a KYC/geo mismatch is a trigger.
P2P complaints
Fiat received from counterparties using stolen funds; the account is frozen once a complaint lands.
What to do, step by step
- Complete full KYC with your own documents; nothing moves without it.
- Keep a record of all correspondence and of exactly what was requested.
- Get an AML report on your addresses before submitting explanations.
- Build a chronological Source of Funds in English.
- If there is no response for three weeks, send a written escalation to compliance citing the case number.
What NOT to do
- Do not pass KYC with someone else's documents: that refusal is irreversible.
- Do not use a VPN to "change jurisdiction" during review; geo-jumps read as evasion.
What Onyx does in your case
- Forensic report on your addresses (Chainalysis/TRM class): what exactly triggered the flag and your real distance from the risk cluster.
- Source of Funds dossier: a chronological reconstruction of your capital with documents, in the format compliance actually reads.
- Communication with KuCoin compliance: one consistent, verified position instead of a pile of scattered tickets.
Frequently asked questions
KuCoin demands KYC on an old account with funds. Is that legal?
Yes: after settling with US regulators the platform must verify everyone. Without KYC the funds stay frozen; this is compliance, not a negotiation.
How long does the withdrawal security review take?
From 1-2 days to several weeks. AML cases with Source of Funds requests can run up to 90 days.
KuCoin no longer serves my jurisdiction. Are the funds gone?
No: there is normally a withdrawal window after KYC. Follow the official procedure rather than waiting.
