# Belgian bank account number (national format) (`be_bank_account`)

> **Draft.** Draft records have not been reviewed yet and may be incomplete or wrong; do not treat them as authoritative for legal or compliance decisions.

Belgian bank account number in the national format used before the IBAN replaced it in payments: 12 digits written as 3, 7 and 2, as in 096-1234567-69. The first three digits are the bank identification code of the National Bank of Belgium, the next seven the account, and the last two the remainder of the first ten digits divided by 97 (97 when the remainder is 0). The same 12 digits follow BE and the two IBAN check digits in a Belgian IBAN (be_iban), so old account numbers are still found in historical data and are converted to IBAN.

- `096-1234567-68` (invalid example) — Check digits do not match
- `BE71096123456769` (invalid example) — IBAN, not the national format
