Identity Verification 101

Overview #

Identity verification checks whether a person is who they claim to be. It may include checking identity numbers, names, date of birth, citizenship or permanent-residence status indicators, deceased status, biometric signals, document authenticity, contact details, and related risk indicators.

Why it matters #

Identity is foundational. If identity is weak, later checks such as credit, criminal record, qualification, employment, beneficiary, account or supplier checks can be misdirected to the wrong person.

How to think about it #

• Identity verification should combine data quality, source reliability and context.
• A correct identity number is not always enough; names, date of birth and other attributes should be considered.
• The purpose determines the depth of the check: onboarding, employment, credit, programme participation and investigation may require different evidence.
• Identity checks should not be used to exclude people unfairly where data quality issues can be resolved.

Common examples #

• Confirming that an applicant’s ID number format is valid before deeper checks are requested.
• Comparing supplied names and date of birth against identity records.
• Flagging possible deceased-status conflicts for manual review.
• Requesting additional evidence when a record cannot be confidently matched.

Responsible use reminders #

• Use identity data only for the purpose communicated or legally permitted.
• Protect identity documents and images as sensitive personal information.
• Document exceptions and manual overrides.
