Root Cause

Turkey's Central Bank (TCMB) mandates that all cross-border wire transfers exceeding $2,000 require the recipient's MERSIS number (Merkezi Sicil Kayıt Sistemi, a 10-digit corporate identifier) for AML compliance; without it, the sending bank rejects the transfer.

土耳其央行（TCMB）规定，所有超过2,000美元的跨境电汇需要收款人的MERSIS号码（Merkezi Sicil Kayıt Sistemi，10位企业标识符）用于反洗钱合规；缺少此号码，汇款银行将拒绝转账。

Dead Ends

Common approaches that don't work:

  1. 98% fail

    Turkish banks require a corporate MERSIS for business entities; personal tax IDs are not accepted for corporate cross-border transfers.

  2. 90% fail

    TCMB aggregates related transactions within 30 days; splitting triggers AML alerts and may freeze the account.

  3. 85% fail

    All Turkish banks licensed by TCMB enforce the MERSIS rule; non-bank processors still need MERSIS for settlement.
