BR-DE-19: The IBAN does not look like a real IBAN. How to fix it
For a SEPA credit transfer (code 58) the account field (BT-84) must hold a formally valid IBAN. This is a warning, not an error.
The rule, in its own words
"Payment account identifier" (BT-84) soll eine korrekte IBAN enthalten, wenn in "Payment means type code" (BT-81) mit dem Code 58 SEPA als Zahlungsmittel gefordert wird.
Fields involved: BT-84, BT-81
What the rule checks
The rule checks the IBAN arithmetically: the country prefix, the length for that country, and the two check digits under the modulo-97 method. It does not check that the account exists or that it is yours, only that the number is internally consistent.
Why files fail it
- A transposed digit. Two swapped figures change the checksum, which is exactly what the check digits are for.
- The IBAN was copied out of a PDF or an email and picked up or lost a character on the way.
- The account number was entered instead of the IBAN, or the country prefix at the front is missing.
- The IBAN belongs to a different country than its length suggests: a German IBAN is 22 characters, an Austrian one 20.
How to fix it
- Compare the IBAN character by character against your bank statement. The fault is almost always one wrong position.
- Spaces do not matter and are ignored; a wrong character does.
- Note that this is a warning, not a refusal. The official report still accepts the invoice. But a wrong IBAN means your money does not arrive, which makes it more important than some genuine errors.
- Our form checks the IBAN as you type, with the same method, and tells you immediately if the check digits do not fit.
