Input rules & validation notes

  • For address services, send structured address fields instead of a single address string when possible.
  • address.street_1 is the street address, including street number and street type.
  • address.street_2 is apartment, unit, building, floor, or extra address line. Send it only when you have it.
  • address.city is city, suburb, district, locality, or neighborhood.
  • address.region is state, province, region, or town.
  • address.postal_code is postcode or postal code.
  • Address-based database services require at least street address and postal code; requests rejected before source lookup are not charged.

​
How to call it

  • first_name
  • full_name
  • identification_number
  • last_name
  • name_match_score

  • Availability: 99.9% per quarter on Didit’s side; downstream source availability varies by country and dataset.
