Geographic Overview
The Belgian national destination code (NDC) +32 89 is a geographic area code assigned to the Genk telephony exchange area, located in the province of Limburg in the Flemish Region of Belgium. This numbering area covers the city of Genk and its surrounding municipalities, including As, Opglabbeek, Zutendaal, and parts of Houthalen-Helchteren and Maasmechelen.

Dialing Formats
When calling a landline in the Genk area from within Belgium, subscribers must use the 0 trunk prefix followed by the area code and the subscriber's seven-digit local number. For example, a local number such as 12 34 56 would be dialed as:
- National format: 089 12 34 56
- International format: +32 89 12 34 56 (when calling from abroad)

Geographic vs. Non-Geographic Usage
Like all Belgian geographic area codes, +32 89 is tied to a specific physical location. However, number portability allows subscribers to retain their number when moving within Belgium, which may result in a number no longer being strictly tied to the Genk area. Nevertheless, the code remains primarily associated with the Genk region and is used for fixed-line PSTN and VoIP services. Calls to +32 89 numbers are typically charged at standard national rates when dialed from within Belgium, and international rates when dialed from abroad.
Caller Instructions
For callers within Belgium, simply dial 089 followed by the seven-digit local number. For international callers, replace the trunk prefix with the Belgian country code +32 and drop the leading zero: +32 89 followed by the local number. Always verify the local number length, as some older numbers may have fewer digits, but the standard format is 7 digits after the area code.
