Identity proofing and verification of an individual

This good practice guide (GPG 45) provides guidance on the identity proofing and verification of an individual using online services.


Identity Proofing and Verification of an Individual


This guide shows how a combination of the following can provide various levels of assurance around proving an identity:

  • the breadth of evidence
  • the strength of the evidence
  • the validation and verification processes carried out
  • a history of the user’s activity

The guidance aims to:

  • provide organisations with an understanding of the capabilities they will need to be able to demonstrate in order to perform identity proofing
  • provide information to independent assessment organisations so that benchmarks or profiles can be developed to support the independent assessment and certification of organisational and technical capabilities
  • establish a common framework establishing requirements for the validation and verification of the identity of individuals
