Besides the standard information, the IBAN format will be mandatory as from 1 July 2019 (see Appendix VI).
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
The beneficiary’s physical full address is recommended.
