Validates whether EU payment messages comply with the November 2026 ISO 20022 structured address field mandate under the EU Instant Payments Regulation. From 9 November 2026, all PSPs in the eurozone must use structured address fields (TownName, PostCode, StreetName) in SEPA Instant Credit Transfer messages — replacing unstructured AdrLine free-text blocks.
Paste a representative address block from your payment messages to check field usage. Use synthetic/anonymised data only. The tool will identify AdrLine vs structured field usage.
