Postal codes in the Netherlands

The first two digits indicate a city and a region, the second two digits and the two letters indicate a range of house numbers, usually on the same street. Consequently, a postal address is uniquely defined by the postal code and the house number. On average, a Dutch postal code comprises eight single addresses. There are over 575,000 postal codes in the Netherlands as of 2017.

Caribbean Netherlands

The three BES-islands, which became part of the country in 2010, do not as yet have postal codes. The address, the town and the island are sufficient for sending post to either island (with "Caribbean Netherlands" as country when sent from abroad). The Dutch government has plans for introducing postal codes on the islands that would be similar to the postal codes used in the European Netherlands.
