Area Code 50 – Naivasha/Narok/Gilgil

Overview of Area Code +254 50

Area code 50 is a geographic National Destination Code (NDC) within the Kenyan numbering plan, assigned to the Rift Valley region covering the towns of Naivasha, Narok, and Gilgil. These areas are located in Nakuru and Narok counties, approximately 80–150 kilometers northwest of Nairobi. The code is used for fixed-line (PSTN) services, and it is also utilized by some Voice over IP (VoIP) operators for geographic numbers.

Geographic Coverage and Administrative Jurisdiction

The 50 area code serves a mix of urban and rural communities. Naivasha is a key commercial hub known for its flower farms and geothermal energy sector, while Gilgil is a smaller town along the Nairobi–Nakuru highway. Narok, located to the southwest, is the gateway to the Maasai Mara National Reserve. The region is administered by the Nakuru and Narok county governments, and the numbering plan falls under the jurisdiction of the Communications Authority of Kenya (CAK).

Dialing Formats

To call a fixed-line number in this region from within Kenya, subscribers must dial the trunk prefix 0, followed by the area code 50 and the subscriber number (typically 6 digits). For example, a local number might be 0 50 234 567. From outside Kenya, callers must dial the international access prefix (e.g., 00 or +), followed by the country code 254, then the area code 50 without the leading zero, and the subscriber number. Thus, the international format would be +254 50 234 567.

Overlay and Numbering Considerations

Currently, there is no overlay code for the 50 area; the code is exclusively used for the Naivasha/Narok/Gilgil region. However, due to the growth of mobile telephony and fixed-wireless services, some numbers may be assigned to operators that provide fixed-wireless or VoIP services, but they remain geographically associated with the area. Subscribers should note that the total length of a Kenyan geographic number, including the leading zero, is 9 digits (e.g., 0 50 234 567).

Caller Instructions

For local callers within the same area code, it is often possible to dial only the subscriber number, but to avoid confusion, it is recommended to always use the full national format. For callers from other regions in Kenya, dial 0 50 followed by the subscriber number. International callers should replace the leading zero with the country code +254 and then dial 50 and the subscriber number. Always verify the number length with the service provider, as some numbers may have been migrated to 7-digit subscriber numbers in recent renumbering exercises.
