# AI告诉欧盟居民仅凭收款人姓名和账号进行SEPA转账，忽略IBAN和BIC

- **ID:** `banking/eu-sepa-transfer-rejection-iban-bic`
- **领域:** banking
- **类别:** config_error
- **错误码:** `REJECTED-IBAN-FORMAT-ERR`
- **验证级别:** ai_generated
- **修复率:** 88%

## 根因

SEPA贷记转账规定要求所有SEPA区域内的欧元支付必须使用IBAN和BIC；国内账号在不同国家的清算系统中不可互操作。

## 版本兼容性

## 解决方案

1. ```
   Retrieve the IBAN and BIC from the recipient's bank statement or online banking portal; enter both in the SEPA transfer form exactly as shown (e.g., IBAN: DE89370400440532013000, BIC: COBADEFFXXX).
   ```
2. ```
   Use the recipient's IBAN validator tool (e.g., iban.com) to generate the IBAN if you have the country, bank code, and account number; then manually enter it.
   ```
3. ```
   If the recipient is a business, request their SEPA Creditor Identifier (SCI) and IBAN from their ERP system; use ISO 20022 XML format for batch payments.
   ```

## 无效尝试

- **** — IBAN is not simply a padded account number; it includes country code, check digits, and bank identifier; domestic account numbers are not IBANs. (95% 失败率)
- **** — SEPA replaced national clearing systems; legacy formats are rejected by the SEPA message validator at the originating bank. (90% 失败率)
- **** — Banks do not maintain cross-border mapping tables; the SEPA scheme requires explicit IBAN/BIC in the payment instruction. (85% 失败率)
