Offices that help you get a BIS number in Belgium

Before attending, ask reception which identity documents and information about the requesting authority to bring; no complete BIS document checklist or fee is available. Have details of any existing Belgian identification number available. If you are actually moving to Belgium, confirm resident registration separately rather than using BIS identification as a substitute. For employment-related identification, your current or future employer can request your NISS through belgianIDpro. Sigedis explains that a BIS number is created by a municipality, employer or competent authority within an administrative case; there is no standalone citizen self-application. Use the locally documented route above when it fits your situation.
