Which area codes exist in the Netherlands?

The Netherlands is divided regionally into different area codes. These prefixes are included in the Numbering Plan of Phone and ISDN Services and were introduced when regional calling became possible. The area code always begins with an access number, such as 0 and ends with the local prefix.
View the complete list of area codes.

Fun fact: before local prefixes were introduced, you needed an operator to manually connect you to the number you wanted to call. An operator answered the call and asked for your city before you could be transfer.

I used to be a customer and switched to a VoIP number, but I didn't like it. I'm back now because I know it works. In addition, the customer service is very fast and helpful.

Professional company with good service at a fair price! What I especially appreciate is that they're constantly improving their services. And they are very helpful!
