受益人账户已开立但被冻结，通常因反洗钱、制裁或监管原因。
AC06 is more serious than AC01 or AC04. The account exists and is active, but is blocked by the beneficiary's bank — typically because of an AML investigation, a court order, a sanctions freeze, or a KYC re-check.
The sender cannot resolve this. The beneficiary must contact their bank to understand and resolve the block. In sanctions cases, funds may be frozen by the regulator and not returned.
