Registration for social housing rewards the calendar rather than the need, which makes the timing of that first sign-up one of the more consequential small decisions after arriving. It affects anyone who might still be here in several years, including people whose current housing is perfectly comfortable.
Genuinely long, and the national average of around seven years hides a wide spread — Amsterdam and Utrecht run more like 10 to 14 years, Rotterdam sits at 5 to 8, and smaller municipalities can be under a year. Register now regardless of whether you need it, because most regional systems (WoningNet and similar) rank you by inschrijfduur — how long you've been registered — not how urgently or actively you're browsing listings. That means someone who signed up five years ago and only just started looking often beats someone with a real housing crunch who registered last month. It costs a small annual fee on most platforms, and since the clock only starts once you're on the list, delaying registration is pure lost time you can't get back later.
