Postal Code 3550 – Heusden,

Postal Code 3550 for Heusden is part of the Belgium postal code system, which uses a numeric code of 4 digits (e.g. 1000). Addresses here are organised as Region → Province → Municipality → Locality.

No building-level records are held for this code in the imported dataset, so only the code and its location details are shown. The absence of records does not mean the postal code is unused.

Couriers, e-commerce checkout forms and address autocomplete tools all rely on the postal code to route mail and to check that a stated address matches the code. Because a postal code identifies a delivery area rather than a single building, two addresses that share the same code can still be some distance apart.

Always write Belgium Postal Code in full when completing a form, including any leading zero. Enter a 4-digit Belgian postal code. Data source: a third-party open dataset. This is a reference snapshot, not a live government feed, so confirm the code with the sender, carrier or postal authority before relying on it.
