📍 Geographic Location of St. Annaparochie
Geographic Coverage and Administrative Jurisdiction
The +31 518 country-code and area-code combination routes calls to the geographic numbering area of St. Annaparochie, a town in the municipality of Waadhoeke, located in the province of Friesland (Fryslân) in the northern Netherlands. This area code serves the administrative jurisdiction of Waadhoeke, which was formed in 2018 through a merger of the former municipalities of het Bildt, Menameradiel, and Franekeradeel. The primary exchange area includes St. Annaparochie itself, along with surrounding villages such as Sint Jacobiparochie, Vrouwenparochie, and parts of the rural Bildt region. The code is assigned to the traditional PSTN network, but it is also used by VoIP providers for fixed-line services within the same geographic footprint.
Dialing Formats and Caller Instructions
For local callers within the Netherlands, the national trunk prefix '0' is dialed before the area code, resulting in the format 0518-XXXXXXX (where X represents the subscriber number). The complete national number length is 10 digits, including the leading zero. For international callers, the format is +31 518 XXXXXXX (or +31518XXXXXXX when dialed without spaces). The subscriber number length varies between 6 and 7 digits, depending on the specific line allocation, but the total number of digits after the country code (including the area code) is always 9.
When calling from abroad, you must replace the leading '0' with the international access code (e.g., '00' from most European countries, or '+' from mobile phones) followed by the country code 31. For example, to call a number in St. Annaparochie from the United States, you would dial 011 31 518 XXXXXXX. From a mobile phone, simply use +31 518 XXXXXXX.
Overlay and Numbering Plan Considerations
As of the current ITU-T E.164 national numbering plan for the Netherlands (managed by the Authority for Consumers and Markets, ACM), the 518 area code has no overlay code; it is the sole geographic code for this region. However, number portability allows subscribers to retain their 518 numbers when switching to a different fixed-line operator, including VoIP providers, even if they relocate outside the traditional exchange area. This means that a number with the 518 prefix may no longer be physically located in St. Annaparochie, but the geographic association remains for administrative and routing purposes.
For callers, this geographic code is not rate-regulated; standard national fixed-line tariffs apply when calling from within the Netherlands, and international tariffs apply when calling from abroad. Emergency services (112) are always free and reachable regardless of the area code.
