ISO 20022 FAQs
-
What is ISO 20022?
ISO, the International Organization for Standardisation, is a global body that develops consensus-based international standards that support innovation and provide solutions to global challenges. It is the next generation standard that focuses on electronic data interchange between financial institutions. It has grown each year and covers the entire financial industry, enabling everything from foreign exchange trading to credit card payments.
-
Why is ISO 20022 important?
ISO 20022 is used by payment systems in over 70 countries and will be the benchmark standard for high-value and instant payment systems of all major currencies. It enables complete and unambiguous data exchange between financial institutions. This will improve the quality of data across the payments ecosystem and reduce industry costs and risk. Richer and better use of data will open new opportunities, as unstructured data that is repeatedly translated and truncated across multiple data formats can lead to ambiguous payments.Depending on the payment types and payment data services you use, it means there will be a need to make changes to the way you send, receive and process domestic and international payments which in turn will bring future benefits.
-
What are the benefits of making these changes as a customer?
The main benefit of adopting the changes of ISO 20022 is the way that it enhances the payment experience for our customers. This can be identified clearly as it reduces the multiple payment schemes and in-house banking formats that are used today to a single industry-wide standard. This will enable our customers to manage and utilise our payment facilities with ease.ISO 20022 also has several other benefits, these include:
- Standard delivery of structured address details to enable straight-through processing.
- The structured address fields will also have an increased character length that will enable our customers to send and receive payments efficiently.
- The same version of the ISO 20022 standard will be utilised for all mass-volume SEPA payments, high-value euro payments and international payments.
-
What is the transition period for making these changes?
The transition period for ISO 20022 will end in November 2025.
-
What payment types are impacted by this change?
For AIB customers, ISO 20022 will bring updates to all SEPA and international payments. These will include SEPA Credit Transfer, SEPA Direct Debit and Multi-Currency Bulk payment files as well as individual payments.

What will happen if I don’t make these changes for November 2025?
If you don’t make the mandatory changes before the transition period ends in November 2025, you can expect that any SCT, SDD and MCY bulk payment files that you upload after this date will fail.
-
Can I use the transition period until it ends in November 2025?
Customers can continue to upload files in the current format or alternatively make the necessary changes to the new format. This is a phased approach. Both formats will be supported and available on the AIB website until November 2025.It would be beneficial for business customers to plan accordingly as this will enable AIB to manage and support your concerns during this transition period.
