Go to Administration → School → Staff numbers. The Staff Number Series card works like admission numbers: turn on Auto-generate staff numbers, pick a preset — Pattern (STF/2026/0001), Numeric only, Year + sequence — or Custom, check the preview and Save.
With auto-generation off, you type a staff number yourself each time you add someone.
The format locks once the first staff number is issued. Staff members whose existing numbers do not match the format are flagged in the directory, where Reissue gives them the next number in the series — the old number stays in the record’s history.
Staff can sign in with their staff number as well as their email or phone.
