Area Code 24 – Nijmegen

Overview of Area Code +31 24

The +31 24 area code is a geographic National Destination Code (NDC) assigned to the city of Nijmegen and its surrounding municipalities in the province of Gelderland, Netherlands. Nijmegen, one of the oldest cities in the Netherlands, is located in the eastern part of the country near the German border. The code serves the greater Nijmegen metropolitan area, including towns such as Beuningen, Groesbeek, Heumen, Mook en Middelaar, and Wijchen.

Geographic Coverage and Administrative Jurisdiction

This code falls under the jurisdiction of the Dutch telecommunications regulator, the Autoriteit Consument & Markt (ACM), which oversees numbering allocation in accordance with the national numbering plan. The area code 24 is specifically designated for fixed-line services within this region, and it is not portable outside the geographic area.

Dialing Formats

• Local dialing (within the Netherlands): When calling a number in the 24 area from another Dutch region, you must dial the trunk prefix 0 followed by the area code and subscriber number: 024 XXX XX XX (e.g., 024 123 45 67).
• International dialing (from outside the Netherlands): Dial the international access prefix (e.g., 00 from most countries, or +) followed by the country code 31, then the area code without the leading 0, and the subscriber number: +31 24 XXX XX XX (e.g., +31 24 123 45 67).

Number Structure and Length

Subscriber numbers within the 24 area code are 7 digits long, making the complete national significant number (NSN) 9 digits (including the area code). The format is 024-XXX XX XX for national dialing and +31 24 XXX XX XX for international calls.

Overlay and Numbering Considerations

Currently, there is no overlay code for the 24 area; the code is exclusively used for Nijmegen and its immediate surroundings. However, due to the increasing demand for telecommunication services, the ACM periodically reviews numbering resources. As of now, no changes are planned, but businesses and residents should be aware that number portability allows them to retain their fixed-line numbers when switching providers, as long as they remain within the same geographic area.

Caller Instructions

• For local callers: If you are within the 24 area, you may dial only the 7-digit subscriber number for local calls (e.g., 123 45 67). However, it is always safe to dial the full national format (024-XXX XX XX) to avoid any confusion.
• For international callers: Always drop the leading 0 of the area code and use the +31 country code. Ensure you have the correct subscriber number, as omitting digits will result in a failed call.

Understanding the correct dialing format is essential for both domestic and international communication with Nijmegen. Whether you are contacting a business, government office, or resident, using the proper prefix ensures your call reaches its intended destination without unnecessary charges or errors.
