📮Netherlands Postal FAQ and delivery guidance

🔢 What is the standard format of Dutch postal codes?

Dutch postal codes consist of 4 digits + space + 2 uppercase letters, e.g., 1234 AB. Letters must be capitalized, and a space between digits and letters is mandatory.

🗺️ How large is the coverage area per postal code?

The first 4 digits indicate a region (e.g., city or district), while the 2 letters pinpoint specific streets or building clusters. One code typically covers around 20 addresses.

✉️ What happens if I write the wrong postal code?

It may cause significant delays or return. Dutch mail sorting relies heavily on postal codes; incorrect formats trigger manual processing, adding 3-5 working days.

🔄 Do Dutch postal codes ever change?

Yes! Codes can be updated due to urban expansion or district reorganization. Verify your address regularly via PostNL's website or local municipality.
