📍 Geographic Location of Heerenveen
Overview of Area Code +31 513
Area code 513 is a geographic National Destination Code (NDC) within the Netherlands' national numbering plan, conforming to ITU-T E.164. It serves the municipality of Heerenveen and its surrounding areas in the province of Friesland. This code is assigned to fixed-line (PSTN) services, and numbers under this prefix are used by residential, business, and government subscribers within the designated geographic area.
Geographic Coverage and Administrative Jurisdiction
The +31 513 area code covers the town of Heerenveen and several adjacent villages, including but not limited to Akkrum, Gersloot, Jubbega, Katlijk, Mildam, Nieuwehorne, Oudeschoot, and Terband. Administratively, these localities fall under the jurisdiction of the Heerenveen municipality, which is part of the province of Friesland. The region is known for its waterways and rural landscape, and the area code reflects the historical telephone exchange boundaries that align with municipal borders.
Dialing Formats and Caller Instructions
For callers within the Netherlands, the national trunk prefix 0 must be dialed before the area code. Thus, a local number in Heerenveen is dialed as 0513-XXXXXXX, where the subscriber number typically consists of seven digits. For international callers, the country code +31 is used, followed by the area code without the leading zero, resulting in the format +31 513 XXXXXXX. For example, a local number might be 0513 612345 (national) or +31 513 612345 (international).
When calling from abroad, you must replace the leading zero of the national prefix with the international access code (e.g., 00 from most European countries, 011 from North America) followed by 31 and then the area code and subscriber number. It is important to note that within the Netherlands, all geographic numbers have a fixed length of 10 digits when dialed nationally, including the leading zero. The area code 513 is not an overlay; it is the sole geographic code for Heerenveen, and there are no plans for an overlay at present.
Numbering and Routing Considerations
Numbers under +31 513 are allocated to fixed-line operators, including KPN, Vodafone (formerly Ziggo), and various alternative carriers. Subscribers may have the option to keep their number when switching providers (number portability), which means that a number with this prefix may not always be physically located in Heerenveen. However, the geographic association remains for administrative and emergency services routing purposes.
For callers, it is essential to dial the full number including the area code, even when calling from a mobile phone within the same region, as mobile networks do not recognize local dialing without the area code. For international callers, always use the plus sign (+) when dialing from a mobile device to ensure proper international routing.
