📍 Geographic Location of Gorinchem
Overview of Area Code 183
Area code +31 183 is a geographic National Destination Code (NDC) assigned to the region of Gorinchem in the Netherlands. Gorinchem, often referred to as Gorkum, is a historic city and municipality in the western part of the province of South Holland. The code serves the city itself and the surrounding towns and villages, including Arkel, Hoornaar, Noordeloos, Schelluinen, and Woudrichem (across the river in North Brabant). The area is known for its well-preserved 17th-century fortifications and its strategic location at the confluence of the Merwede and Linge rivers.
Dialing Formats
When calling a landline in Gorinchem from within the Netherlands, you must use the full national number: 0183 followed by the subscriber's 6-digit number. For example, a local number might be dialed as 0183 123456. From abroad, you would dial the international prefix (00 or +), then the country code 31, followed by the area code without the leading zero, and the subscriber number: +31 183 123456.
Geographic Coverage and Administration
The 183 area code falls under the jurisdiction of the Dutch telecom regulator, the Authority for Consumers and Markets (ACM), which oversees the allocation of numbering resources. The geographic area covered by 183 is part of the South Holland province, but it also includes a small part of North Brabant due to historical telecom boundaries. The region is served by several telecom operators, and since the liberalization of the Dutch telecom market, subscribers can choose their fixed-line provider, but the geographic number remains tied to the physical location of the line.
Overlay and Numbering Plan Considerations
As of now, there is no overlay code for the 183 area. The Netherlands uses an open dialing plan for national calls, meaning that the area code is required for all calls, even local ones. The number length for geographic numbers in the Netherlands is 9 digits including the leading zero of the area code, but the subscriber number length can vary. In the 183 area, subscriber numbers are 6 digits long, making the total national number 10 digits (0 + 183 + 6 digits).
Caller Instructions
For local callers within the 183 area, you must still dial the full national number, including the area code. For callers from other parts of the Netherlands, simply dial 0183 followed by the local number. For international callers, replace the leading zero with the +31 country code. Always ensure you have the correct subscriber number, as numbers are not portable across geographic areas in the Netherlands; they are tied to the physical line.
