The Labour Support Unit (LSU) number is the local staff members employee number. So providing this is the fastest way to verify someone's employment with the Ministry of Defence (MOD). However, there are other searches that can be completed to see whether employment can be confirmed. Although these searches do take longer to complete, they could help to verify whether someone was employed by the MOD or another part of Her Majesty's Government (HMG). If the applicant does not have an LSU number (because they were not directly employed by HMG) the applicant may still be eligible for relocation dependent on their particular status.
