📍 Geographic Location of Assen
Geographic Coverage and Administrative Context
The +31 592 numbering block is a geographic National Destination Code (NDC) assigned to the city of Assen, the capital of the province of Drenthe in the northeastern Netherlands. The code covers the urban core of Assen and its immediate surrounding municipalities, including the villages of Kloosterveen, Marsdijk, and parts of the rural Drenthe countryside. As a geographic code, it is tied to the PSTN (Public Switched Telephone Network) infrastructure of the region, although calls may be delivered over IP-based trunks by operators.
Dialing Formats and Procedures
- National dialing (within the Netherlands): 0592 XXX XXX (where X represents the subscriber number). The national trunk prefix '0' is required before the NDC.
- International dialing (from abroad): +31 592 XXX XXX (omit the leading '0' of the national prefix). For example, a caller from the United States would dial 011 31 592 XXX XXX.
- Local dialing within Assen: In most of the Netherlands, local calls still require the full national number, including the area code, due to the absence of a distinct local dialing scheme. Thus, even within Assen, you must dial 0592 followed by the subscriber number.
Numbering Structure and Length
Subscriber numbers within the 592 area code are seven digits long, making the complete national number (including the '0' trunk prefix) 10 digits: 0592-XXX XXX. The international format, +31 592 XXX XXX, also totals 10 digits after the country code. This structure is consistent with the Netherlands' national numbering plan, which allocates geographic NDCs of varying lengths, but all subscriber numbers are seven digits for geographic codes.
Overlay and Number Portability
As of the latest ITU-T E.164 national numbering plan updates, there is no overlay code for Assen; the 592 code is the sole geographic code for the area. However, number portability is fully implemented in the Netherlands. This means that a subscriber who originally had a 592 number may have moved to another city or switched to a VoIP provider, yet retained the 592 number. Consequently, calling a 592 number does not guarantee that the line is physically located in Assen; it only indicates the original assignment. This is an important consideration for businesses and individuals relying on geographic codes for routing or location-based services.
Caller Instructions
- For local callers (within Assen): Always dial the full national number: 0592 XXX XXX.
- For national callers (elsewhere in the Netherlands): Dial 0592 XXX XXX.
- For international callers: Dial the international access prefix (e.g., 00 from most European countries, 011 from North America) followed by 31 592 XXX XXX.
When calling from a mobile phone, the same rules apply; the '0' is required for national calls, and the international format is used when dialing from abroad. There are no special charges for calling a geographic number from a mobile, but standard mobile tariffs apply.
