What are temporary UPNs and when are they allocated?
Temporary UPNs are allocated when a school receives a learner who is already likely to have a UPN, but the receiving school does not yet know the UPN. The formula for temporary UPNs is identical to that for permanent UPNs, except that characters 11-13 are a two-digit serial number plus a letter (rather than a three-digit serial number), for example, G80120000101A. Temporary UPNs should be replaced immediately when the valid UPN is known.
