📍 Geographic Location of Warffum
Geographic Coverage and Administrative Jurisdiction
The +31 595 area code is a geographic National Destination Code (NDC) assigned to the northern region of the province of Groningen in the Netherlands. It serves the municipality of Het Hogeland, with the principal town being Warffum. The code covers a cluster of rural communities and villages, including Usquert, Uithuizen, Uithuizermeeden, Roodeschool, and Eemshaven, extending towards the Wadden Sea coast. Administratively, this area falls under the province of Groningen, which borders Germany to the east and the Wadden Sea to the north.
Dialing Formats and Caller Instructions
Within the Netherlands, calls to numbers in the 595 area require dialing the full national number: 0595 followed by the subscriber's six-digit local number. For example, a local call to a Warffum landline would be dialed as 0595 123456. When calling from abroad, the international format must be used: replace the leading zero with the country code +31, resulting in +31 595 123456. Note that the national trunk prefix '0' is omitted when dialing from outside the Netherlands.
Numbering Structure and Overlay Considerations
All Dutch geographic numbers, including those in the 595 area, consist of 9 digits after the country code, formatted as NDC (2-3 digits) plus subscriber number (6-7 digits). In the 595 case, the NDC is three digits, and the subscriber number is six digits. Currently, there is no overlay code for this region; the 595 code is exclusively assigned to the Warffum area. However, number portability allows subscribers to retain their 595 numbers when moving to other service providers, including VoIP operators, which may result in calls being routed to non-geographic locations.
Economic and Infrastructure Context
The region is known for its agricultural landscape, historical villages, and the Eemshaven port, a significant energy hub with data centers and a growing digital infrastructure. Despite this, the 595 area remains primarily residential and rural, with a relatively low population density. The area code is managed by the Dutch Authority for Digital Infrastructure (RDI), which oversees the national numbering plan in accordance with ITU-T E.164 recommendations.
Practical Usage Tips
- For local callers: Always dial the full national number, including the leading zero.
- For international callers: Use +31 595 and omit the leading zero.
- Be aware that numbers may be ported to mobile or VoIP services, so the geographic association is not absolute.
