What's in the PDF

A 23-point migration checklist for the November 2026 pacs.008 structured-address deadline — distilled from EPAA working-group output, SWIFT CBPR+ guidance and the 308-bank RedCompass survey.

The checklist covers:

• Inventory — auditing your outbound pacs.008 traffic for unstructured-address residue
• Mapping rules — decomposing free-text addresses into ISO 20022 PostalAddress slots (TwnNm, PostCode, Ctry, BldgNb, StrtNm, Dept, SubDept)
• Generator updates — patching your pacs.008 templating layer so every new message emits structured fields by default
• Receiver fallback — keeping legacy unstructured handling alive for non-migrated counterparties
• End-to-end test harness — scheme-specific test cases for SWIFT, SEPA, CHAPS, T2
• Cutover signalling — coordinating with your scheme manager on the activation date
• KPI reporting — bytes-on-the-wire of structured-vs-unstructured per FI, week over week

Use it as a project tracker through cutover.

Why I wrote it

I wrote the pacs.008 deadline analysis earlier this month. Several readers asked for a project-tracker version — something they could circulate to their migration squad. This is that.

If your bank is behind on the migration, get in touch — I do selective ISO 20022 transformation consulting and can usually shorten a residual programme by 4-6 weeks with the right intervention point.
