Temporary UPNs should be replaced immediately once the valid UPN is known with the temporary UPN being reported in the ‘former UPN’ field.
Please refer to the Department for Education (DfE) guidance regarding issuing of permanent and temporary UPNs): Unique Pupil Numbers (UPNs): a guide for schools and local authorities
To amend a UPN please go to the student profile, to the extended tab and under school information take a copy of the temporary UPN if required, delete this out and enter the correct UPN, scroll to the bottom and save.
