ISO2022 for corporates

ISO 20022 for corporates

ISO 20022 is key to transforming the payments industry, improving transparency and security to support financial transactions and provide richer and more structured data.

What is ISO 20022?

Despite the rapid evolution of technology over the last 40 years, messaging formats have remained largely unchanged.

Finally, the world’s biggest payment schemes, banks and SWIFT are coming together to adopt a single messaging standard across the globe, ISO 20022 XML. 

Over time, this XML format will be used across the payments ecosystem, becoming the dominant messaging format.

Every business day, millions of transactions are completed across the world.

But sending and receiving payments between different schemes can still be challenging.

ISO 20022 is about to change that.

It’s the new global standard to make electronic payment messages more easily understood across the globe.

ISO 20022 provides much richer payment data that could enable businesses to improve reconciliations, consolidate transactions, achieve efficiencies, and get great insights on their customers’ behaviour.

Banks and market infrastructures like SWIFT are migrating to ISO 20022.

Getting ready to meet the new payment data requirements will be a big undertaking.

As a minimum, corporates will need to check the impacts of ISO on their payments and reconciliations and whether they need to update internal systems.

At Barclays, we’re on the ISO 20022 journey.

We’re here to help you stay ahead of the payment revolution.

What does this mean for corporates?

Today, a lot of payment information is captured in an unstructured format and there are restrictions on the amount of data we can include within the payment message. ISO 20022 XML introduces richer data into payment flows and provides better structure to the way data is captured in these messages.

Whilst most corporates are not required to migrate to the new XML format, it is mandatory for Barclays and other financial institutions to use XML. As we support clients through this transition and minimise disruption from this industry-wide change, we may need you to provide richer data to process your transactions with Barclays.

Clients using SWIFT for Corporate can continue to use SWIFT MT formats as they are not being decommissioned for corporate users.

What are the enhanced data requirements?

Even if you choose not to migrate to the new XML format, ISO 20022 introduces some new data requirements which will require your attention.

For any business using CHAPS, Cross Border or Euro High Value payments, the introduction of structured addresses and remittance information will impact you. For CHAPS payments, you will need to start including Purpose of Payment codes, beginning with certain types of property transactions.

These changes will all support a more frictionless payment process.

Terms you need to know

Purpose of Payment codes (PoPs) are codes which are added to the payment instruction to describe the reason for making a payment.

Structured remittance data will introduce standardised formats for remittance information relating to your transactions.

A structured address will standardise the way addresses are captured in one specific format.

A Legal Entity Identifier (LEI) is a reference code which uniquely identifies a distinct legal entity, that engages in a financial transaction.

What are the benefits of migrating to ISO 20022?

If you do choose to migrate to the new XML format, you can expect to get a more efficient and standardised payments experience, both domestically and across the globe.

Although the change is driven by payment schemes and SWIFT, there are many other benefits your organisation and customers could gain by migrating to ISO 20022 XML.

Operational efficiencies / innovation opportunity

Enhanced data available to you may have potential benefits for improving your reconciliation and cash flow forecasting.

Reduced costs

By streamlining processes, you can be more efficient in managing and organising your data and require less manual intervention, ultimately saving costs in maintenance.

Better Analytics

Richer, more structured data offers opportunities to better capture data which can help inform decision making.


More granular, quality data ultimately improves transparency and can lead to a better experience for customers and end users.

What do you need to do?

How to prepare

We recommend that all clients take the time to evaluate the impact this new standard could have on their business and consider the benefits of migrating to XML formats.

Even if you choose not to use XML, it is likely you will need to consider how your business will manage the new data elements listed above.

Barclays are here to support you through this major change across the industry. Please contact your relationship team for more information about the ISO 20022 transition and how we can support your individual needs.
