Online KYC checks. Know more before you say yes.

Verify names, dates of birth and addresses online.

• Name

  First name and surname, with a combined name assessment accounting for known aliases and spelling variations.

• Date of birth

  Whether the supplied date of birth matches the identity record.

• Full address

  Whether the supplied address matches, including the house or flat number.

• Postcode

  Whether the postcode matches an address on file.

First name and surname are required to submit a check. Include date of birth, address and postcode when you have them.

See what matched. Know what needs attention.

Every completed check returns one overall outcome, so you can route the customer without working it out from individual field results.

Add KYC checks to your onboarding with one API integration.

Send customer details and receive the verification outcome, field-level results and supporting information in the same response.

Submit a first name and surname, then add date of birth, address and postcode to check more of the identity. The API returns an overall decision alongside individual field results. UK coverage is available now.
