International Address Cleanse

Cleanse Address now matches addresses outside the UK. Pass context with an ISO 3166-1 alpha-3 country code, such as context=USA or context=FRA, and the API returns the closest matching address from that country's dataset. Requests without context cleanse against the UK, as before.

Details

  • One response shape: Every country returns a standardised address in match, the source record in match.native, and the same confidence score and Match Level indicators
  • Coverage follows your key: The address datasets your API key is licensed for decide which countries it can cleanse
  • Rebuilt matching: A new ranking model improves match accuracy for UK and international addresses, particularly AddressBase Premium and Royal Mail PAF records
  • Recalculated confidence scores: Matches, scores and Match Levels may differ from earlier responses. If your integration accepts matches above a fixed confidence threshold, re-check that threshold against current results
  • No charge for no match: A cleanse that returns a match costs a lookup. A no-match response is free
