The exceptions and attestation processes for Voter Authority Certificates and Anonymous Elector’s Documents
You must require applicants to provide additional evidence where you consider it is necessary to verify the applicant’s identity. This may be because:
they are unable to state their personal identifier(s)1
the personal identifiers cannot be matched against DWP records, or
an applicant cannot be matched against local data, or you choose not to use this option
This additional evidence may be in the form of supporting documents verifying that they are who they say they are, known as the exceptions process, or by providing a statement from another individual confirming the applicant’s identity, known as the attestation process.
