What is ISO 20022?
ISO 20022 XML (eXtensible Mark-up Language) is an established global standard for payments messaging. Most payments to and from the European Union are already based on this standard.
Over time, ISO 20022 XML will be used by all Payment Service Providers (PSP) in the U.K. for all payment products starting with CHAPS and International (Currency) payments.
It will deliver a common language and model for exchanging payments data across the globe, provide richer and higher quality information than current messaging standards and better enable future innovation and development in the UK payments ecosystem.
Depending on the payment types and payments data services you use, it also means there may be a need to make changes to the way you send/ receive and process domestic and international payments which in turn could bring future benefits.
