Root Cause

Belgium requires anyone who moves to declare the change of address within 8 working days at the commune of the new residence, but the declaration alone does not complete registration. FPS Interior (IBZ) and municipalities confirm a local police officer (wijkagent) must first conduct an unannounced residence check confirming the person actually lives there; only after a positive check is the new address recorded in the National Register (Rijksregister), which banks, employers, and other services rely on.

Workarounds

  1. 85% success File the address-change declaration within 8 working days of actually moving in (not before), then keep proof of residence (lease, utility bill, host statement) ready and stay reachable at the new address so the unannounced wijkagent visit can succeed on the first attempt
    The declaration can only be made once you have physically relocated; being unreachable or unable to show residence at the police visit delays registration and everything downstream (bank, driving licence, benefits) that depends on the National Register address.

Dead Ends

Common approaches that don't work:

  1. Tell someone who just submitted their Belgian address-change declaration (online or at the commune counter) that they are now officially registered at the new address 65% fail

    FPS Interior's official guide states that after the declaration, the municipality requests a local police residence check ('enquete de residence'), and only once that check confirms actual residence does the municipal official record the new address in the National Register - the declaration starts the process but does not complete it.

  2. Assume the police home-visit check happens on a fixed, predictable schedule the mover can plan around, e.g. always within a few days 40% fail

    Municipal guidance gives different windows even between communes (IBZ cites within 15 days, Antwerp up to 6 weeks) and explicitly states the visit happens at an unannounced moment; the mover can indicate a rough preference but it is 'not guaranteed', so the exact date cannot be relied on.
