Bankline ISO 20022 FAQs

We will provide an update with further information on when support for MT format payment imports will end. These formats can continue to be used by customers for the time being.

However, as MT formats are being replaced by MX formats across the industry, and with no provision for enhanced data fields in MT message types, it would be prudent to plan to migrate to an alternative format (ISO 20022 MX based or Bankline CSV) by November 2025.

Some customers may find they need to switch from MT messages earlier. For example if you are making certain property related CHAPS payments then from May 2025 you will need to supply an appropriate purpose code, and the MT message format has no field to supply this in.

Customers can provide like for like data in ISO 20022 MX formats for Faster Payment imports today, however enhanced data will not be supported for Faster Payments at this time. We will provide notification to customers when this will be supported.

Payments that don’t need enhanced data included can continue to be imported using other import formats, while they remain available for use. We’ve also extended our CSV format to allow for enhanced data that will be made mandatory. While you don’t have to move to ISO 20022 formats, they are likely to offer benefits that cannot be provided using the CSV format.

ISO 20022 delivers a common language and model for exchanging payments data across the globe, provides richer and higher quality information than current messaging standards and better enables future innovation and development in the UK payments ecosystem.

As a Bankline customer, you can already adopt ISO 20022 MX formats on a like for like basis for all import payment types.

Enhanced data for SEPA Credit Transfers became available from March 2024. Enhanced data for CHAPS payments is available from February 2025. Make sure you’re using the most up to date version of the XML import guide, which includes specific guidance on CHAPS payments found on Bankline.

You can also access a Bankline online community on Swift MyStandards where you’ll find interactive format information and be able to test your files to get feedback on any formatting issues.

You’ll find support guides and information on Swift MyStandards at Bankline Help and Support.

For Bankline File Import:

If you’re using the Bankline CSV format we’ve updated our CSV guide to include the enhanced data that can now be included.

If you’re using ISO 20022 formats you can view the latest XML pain.001.001.09 file import guide, and also visit our Bankline online community on ‘Swift MyStandards’. We’ve created a Bankline Swift MyStandards guide to help you get registered and find the Bankline information and testing portal.

You’ll find support and all the guides mentioned above in the ‘Importing’ section at Bankline Help and Support.

If you’re a Bankline Direct customer, you can visit NatWest Swift MyStandards for the latest ISO 20022 payment format guides (the formats differ to Bankline so make sure you’re accessing the right community). We also have format translation documentation to help you identify where key information from you existing format will be entered in the ISO 20022 MX formatted payment.

For business and corporate payments, customers will submit Customer Credit Transfer Initiation pain.001.001.09 format import files.

Hybrid addresses will require the use of structured town and country fields while other address elements can remain unstructured.

If you’re a Financial Institution, you’ll submit FI to FI Customer Credit Transfer pacs.008.001.08 files when making payments on behalf of your own customers. Please note that due to the nature of this message type, each uploaded file to Bankline will contain one transaction.

As bank-wide ISO 20022 changes are rolled out you’ll start to notice the following differences in some of your CHAPS payment advices.

The ‘Your Reference’ field in the top right might have extra information, shown with a ‘+’ sign. If needed, this extra information can be found in the ‘Payment Details’ section of your advice.

Your address will be included on the top left corner of your advice. If you need to make changes to the address linked to your account, see How do I change my business address?

The ‘Beneficiary account number’ now includes the full sort code and account number (not just the account number).

The ‘Charge type’ will now be blank for some payments.

The ‘Our Reference’ field will now include references starting ‘OPF’, which helps us to identify a payment through bank systems.

The ‘Beneficiary bank ID’ field will now include the Clearing System Identifier for some payments, such as ‘GBDSC’, which helps to identify a UK domestic sort code.

We have started to introduce ISO 20022 based reporting into Bankline with individual Camt.054 Debit and Credit advices available from the Original Bankline Payment Advice screens. And we plan to increase the level of detail provided in these advices in the future.

  You'll ll need to be in the Original Bankline screens.

• Once in Original Bankline, click ‘Account information’ on the left-hand side menu, and go to either:
• ‘View statements’ and select the account and dates you wish to view
• Or ‘View account balances’ and click on ‘Search Transactions’ for the account and dates you need
• Take a look under the ‘Payment advice’ column, and you’ll see ‘View’ if there’s a payment advice available for that individual entry.
• After you click ‘View’, you’ll be able to see the option ‘Export Camt.054’ to the bottom right of the screen, which will export the payment advice as a Camt.054 xml file.

As bank-wide changes are rolled out you’ll start to notice the following differences in some of your CHAPS payment narratives. The transaction code will display as CHP from the day the payment is made. The bank’s reference shown in your statement will start with ‘OPF’ followed by nine numbers. You’ll also now be able to see the full five lines of narrative information about the CHAPS on the same day the payment is made.

LEIs, purpose codes and structured addresses submitted in outbound payments will not be included in statement downloads, regardless of format.

We will be investigating the best way to incorporate the enhanced data that MX messaging makes available into Bankline’s screens, PDF’s, and other exported outputs.
