Which area codes does the Netherlands have?

The Netherlands is divided regionally into various different area codes. These prefixes are included in the Numbering Plan of Phone and ISDN Services and were first introduced when local telephony became possible. A Dutch prefix always starts with an access number, such as a 0 and ends with the local prefix.

Fun detail: before local prefixes were introduced, operators were needed to manually transfer your call. The operator would always need your city before transferring you.
