Belgium Address Format (2026) — Fields & Examples

The field order, postal-code rules, a correct Belgium address example, and a generator with copy and CSV/JSON export.

By Charlie Simmon ·

A Belgium address is easier to get right when you keep the fields in the local order. This guide shows the order, a worked example, and the mistakes that most often break forms and labels.

The examples are synthetic. They use real city and region names with generated street numbers, so you can test a form without pointing at a real household.

How to write a Belgium address

Use this order for a Belgium address. If a form gives you separate fields, fill them one by one rather than pasting the whole block into the street field.

  • 1. Street address
  • 2. Apartment or unit
  • 3. Postal code
  • 4. City
  • 5. Country

Postal code rules

Yes. Belgium uses a postcode. Every generated result includes one, and the fixture values are format samples rather than live postal validation.

The Postcode is written with the address, not stored on a separate line in most forms. The generator keeps it as its own field so you can copy it independently.

City fixtures used by the generator

These are the city, region, and postal fixtures behind the Belgium generator. They are examples for format testing, not a complete postal directory.

Common mistakes

Most address errors are field-order or field-boundary errors, not typing errors.

  • Putting the house number after the street name when the local convention expects it before, or the reverse.
  • Dropping the postcode or changing its format to match a different country.
  • Using a residence or mailbox address for a purpose that requires a physical operating address.

Use this order: Street address → Apartment or unit → Postal code → City → Country. Keep each field separate when the form provides separate inputs.
Does Belgium use postal codes?+
Yes. Belgium uses a postcode. Every generated result includes one, and the fixture values are format samples rather than live postal validation.
Can I use this Belgium address for shipping?+
No. The street and unit numbers are generated. Use the sample for forms, mockups, and QA, not for delivery or identity checks.
