📍 Geographic Location of Oss
Geographic Coverage and Administrative Jurisdiction
The +31 412 area code is a geographic National Destination Code (NDC) assigned to the municipality of Oss, located in the province of North Brabant in the southeastern Netherlands. This code serves the city of Oss and its surrounding villages, including Berghem, Haren, Macharen, Megen, and Ravenstein. As a geographic allocation, the prefix is tied to the PSTN infrastructure of this specific region, and calls to +31 412 numbers are routed to fixed-line subscribers within this defined area.
Dialing Formats and Caller Instructions
For domestic callers within the Netherlands, the area code is dialed as 0412 followed by the subscriber's 6-digit local number, resulting in a total national significant number of 9 digits (0 + NDC + subscriber number). For example, a local number in Oss would be dialed as 0412 123456 from any other part of the country.
International callers must replace the leading zero with the country code +31, omitting the trunk prefix. Thus, the same number would be dialed as +31 412 123456 from outside the Netherlands. When calling from a mobile phone, the plus sign (+) is typically used to denote the international access prefix, but it can be replaced with the appropriate international exit code (e.g., 00 from most European countries).
Overlay and Numbering Plan Considerations
As of the current ITU-T E.164 national numbering plan, the 0412 area code does not have an overlay code. The Netherlands employs a closed dialing plan, meaning that all national numbers must be dialed with the full area code, even for local calls. This practice ensures unambiguous routing and supports number portability, allowing subscribers to retain their numbers when switching providers, though the geographic significance of the code remains for routing purposes.
Practical Usage and Services
Numbers under +31 412 are primarily used by residential and business fixed-line services, including PSTN and VoIP-based subscriptions. They are also used for fax lines and alarm systems. For businesses operating in Oss, having a local geographic number can enhance local presence and customer trust. Callers from abroad should be aware that international tariffs apply, and the cost of calling a Dutch geographic number varies by the caller's carrier and the destination country's settlement rates.
