From November 15, 2026, payment messages in the SEPA schemes and on Swift’s cross-border CBPR+ service will no longer be allowed to carry payer and payee addresses as free text. The European Payments Council (EPC) is banning unstructured addresses from SEPA Credit Transfer (SCT), SEPA Instant Credit Transfer (SCT Inst), and SEPA Direct Debit (SDD) on the same date that Swift does so for CBPR+. Only structured or hybrid addresses will be accepted.
Instant payments, Wero, and stablecoins have taken the headlines, but for bank back offices this single address field is the most concrete deadline of fall 2026. It is the last big step of the ISO 20022 migration, and by several observers’ accounts much of the industry is not ready. With four months to go, 65% of messages are reportedly still noncompliant, and 44% of banks are behind schedule.
Free-text addresses defeat automated screening
Many payment messages still carry the parties’ addresses as blocks of free text: two lines of 70 characters, with no structure, mixing building number, street, postal code, and town. A person can read that. A machine can’t, and anti-money laundering checks, sanctions screening, and automated reconciliation all depend on machine-readable data. ISO 20022 therefore puts each component in its own tagged field.
| Format | Description | Status |
|---|---|---|
| Structured | Each element in a dedicated field: Street Name, Building Number, Post Code, Town Name, Country Code | Recommended (end target) |
| Hybrid | At minimum Town Name and Country Code structured, plus up to 2 lines of free text | Accepted (transition step) |
| Unstructured | Free text only (2 × 70 characters) | Banned from Nov. 15, 2026 |
SEPA lines up with Swift’s annual release
The date was chosen on purpose. It matches Swift’s annual Standards Release in November 2026, a year after CBPR+ ended the coexistence period between the legacy MT format and ISO 20022 for cross-border payments. The European Payments Council aligned the SEPA schemes concerned, credit transfers (SCT), instant credit transfers (SCT Inst), and direct debits (SDD), on the same switch so that banks don’t have to run two competing timetables. The move caps a migration that began in 2023: after converting the messages, the industry now has to fix the quality of the data they carry.
Readiness still lags
Banks, corporates, vendors, and merchants all have work to do
- Banks and PSPs: adapt payment engines, counterparty databases, and sanctions screening engines to send and accept structured addresses, and handle incoming
pacs.008messages in both formats. - Corporates and large billers: clean up and enrich the address data in their customer and supplier databases, which has often been stored as free text for years.
- Software vendors and integrators: update connectors, payment initiation files (pain.001), and APIs so that the structured fields reach all the way to the payer.
- Merchants and marketplaces: check that their payment providers pass on compliant data, or risk seeing settlements blocked in the middle of peak season.
Five steps to take before November
- Map the flows that still carry unstructured addresses, both outgoing and incoming.
- Move to the hybrid format first, with town and country structured. It is the safety net that avoids rejections without a full rebuild.
- Start a data quality project to gradually parse existing records into the fully structured format.
- Test acceptance of incoming messages in both formats under real conditions, without waiting for the Standards Release.
- Avoid a “big bang.” The EPC built in a grace period precisely so that firms can migrate in stages.
Structured addresses look like a dry subject, but they are the invisible foundation of payments’ higher-profile projects. Without clean, machine-readable data, fraud prevention, sanctions screening, and automated reconciliation of instant transfers can’t deliver what they promise. November 15, 2026, won’t make the front page, but it will decide how smoothly millions of payments a day flow. For payments teams that haven’t started, this summer is the time.
