# AI告诉外国供应商通过IBAN接收土耳其付款，但未提及土耳其银行对超过1,000美元的跨境B2B转账需要MERSIS号码

- **ID:** `banking/turkey-iban-verification-mersis`
- **领域:** banking
- **类别:** config_error
- **错误码:** `TCMB-MERSIS-1000`
- **验证级别:** ai_generated
- **修复率:** 79%

## 根因

根据土耳其中央银行（TCMB）2023年生效的规定，所有超过1,000美元的跨境B2B付款要求付款人提供收款人的MERSIS号码（10位企业注册ID），以符合CBRT的反洗钱框架；缺少此字段的转账将被银行拒绝。

## 解决方案

1. ```
   Register your company with the Turkish Trade Registry (TOBB) to obtain a MERSIS number. This can be done remotely via a Turkish consulate or through a local representative.
   ```
2. ```
   Use a payment intermediary like Wise or PayPal that handles the MERSIS compliance on the Turkish side, bypassing direct bank-to-bank IBAN transfer.
   ```
3. ```
   Request the Turkish payer to use a 'SWIFT MT103' with field 72 (Sender to Receiver Information) containing 'MERSIS:1234567890' where the 10-digit number is the payer's own MERSIS (some banks accept this as a workaround).
   ```

## 无效尝试

- **Split the payment into multiple transfers under $1,000 each** — Turkish banks aggregate same-day transfers from the same payer to the same beneficiary; if cumulative exceeds $1,000, the MERSIS requirement triggers (70% 失败率)
- **Use a personal account instead of a business account** — Personal accounts have even lower thresholds (500 USD) and require TC kimlik number (Turkish ID) for the recipient, which a foreign supplier cannot provide (85% 失败率)
- **Ask the Turkish payer to use a different bank that doesn't enforce this rule** — All Turkish banks are bound by TCMB regulation; non-compliance results in fines for the bank, so they uniformly enforce MERSIS requirements (90% 失败率)
