Besides the standard information, the full beneficiary's name (no initials) and the full beneficiary's address are mandatory.
A clear reason / purpose of payment is recommended and consists of a full written description (in English) of the nature of payment to be provided in the remittance information. For example: providing an invoice number without guiding text is considered as insufficient and can result in errors or delays.
Example: Payment of travel expenses – invoice n° 123456789
Additionally, it is mandatory to provide next to the SWIFT BIC code, the beneficiary's bank branch routing code consisting of 5 digits.
