# AI告诉外国供应商通过IBAN接收土耳其付款，而未提及土耳其银行要求超过2,000美元的跨境交易提供MERSIS号码

- **ID:** `banking/mersis-verification-required`

- **修复率:** 78%

## 根因

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。

## 解决方案

1. ```
   Register with MERSIS through the Turkish Ministry of Trade (https://mersis.gtb.gov.tr) to obtain a 10-digit corporate ID; provide this to the payer.
   ```
2. ```
   Use a correspondent bank in a third country (e.g., Deutsche Bank in Germany) that does not require MERSIS for onward transfer, but note additional fees.
   ```
3. ```
   Keep individual invoices under $2,000 to avoid the MERSIS threshold, but ensure no aggregation within 30 days.
   ```

## 无效尝试

- **** — Turkish banks require a corporate MERSIS for business entities; personal tax IDs are not accepted for corporate cross-border transfers. (98% 失败率)
- **** — TCMB aggregates related transactions within 30 days; splitting triggers AML alerts and may freeze the account. (90% 失败率)
- **** — All Turkish banks licensed by TCMB enforce the MERSIS rule; non-bank processors still need MERSIS for settlement. (85% 失败率)
