Bank identifier code specified in the message has an incorrect format (formerly IncorrectFormatForRoutingCode).

Definition from the ISO 20022 External Code Sets, 2Q2026 (published 28 Aug 2026).

What it means in practice

In a pacs.002 or pain.002 status report, a status reason code explains why a payment instruction was rejected (RJCT) or why it has another status. It sits in TxInfAndSts/StsRsnInf/Rsn/Cd.

The bank identifier in the payment is wrong: a BIC with the wrong format, a BIC that does not exist on the network, or a BIC that does not belong to the bank of the account.

Format errors are easy to catch before sending. A BIC that is well formed but wrong for the beneficiary is not, which is why this code still appears often.

What to do

  • Check the BIC format with the BIC checker, then confirm the BIC with the beneficiary or in a licensed directory.
  • Make sure the BIC in CdtrAgt is the bank that holds the account, not an intermediary.
  • Fix the data in the payment order and send a new payment with a new reference and a new UETR. A rejected or returned payment cannot be repaired and resent under its old identifiers.
