Area Code 45 – Kajiado/Ngong/Loitokitok/Athi River

Overview of Area Code 45 (Kenya)

Area code 45 is a geographic National Destination Code (NDC) within the Kenyan numbering plan, administered under the Communications Authority of Kenya (CAK) in accordance with ITU-T E.164 recommendations. It serves the southern Rift Valley and parts of the former Rift Valley Province, specifically covering the towns of Kajiado, Ngong, Loitokitok, and Athi River. These areas are strategically located near Nairobi, and the code is essential for routing calls to fixed-line subscribers within this region.

Geographic Coverage and Administrative Jurisdiction

The 45 area code encompasses the Kajiado County, which borders Nairobi to the south. Key towns include:

• Kajiado – the county headquarters, a rapidly growing urban center.
• Ngong – a suburb of Nairobi, known for its scenic hills and residential estates.
• Loitokitok – a town near the Tanzanian border, at the foot of Mount Kilimanjaro.
• Athi River – an industrial and residential town along the Nairobi-Mombasa highway.

Administratively, these areas fall under the Kajiado County government, and the code is allocated to fixed-line services provided by licensed operators such as Telkom Kenya and other facilities-based operators.

Dialing Formats

Understanding the correct dialing format is crucial for both local and international callers.

• Local calls (within Kenya): To call a fixed line in Kajiado, Ngong, Loitokitok, or Athi River from other parts of Kenya, you must dial the trunk prefix 0, followed by the area code 45, and then the subscriber number. For example, to reach a number in Ngong, you would dial: 045 XXXXXX.
• International calls (from outside Kenya): Callers from abroad should dial the international access prefix (e.g., 00 or +), followed by Kenya’s country code 254, then the area code 45 (without the leading zero), and the subscriber number. For example: +254 45 XXXXXX.

Note that the subscriber number length for geographic codes in Kenya is typically six digits, making the total national significant number (NSN) nine digits (including the leading zero).

Overlay and Numbering Considerations

As of the latest CAK updates, there is no overlay code for the 45 area; it remains a standalone geographic code. However, due to the proximity to Nairobi and increasing demand for fixed-line services, the CAK may introduce overlay plans in the future. Subscribers in this region can also use VoIP and mobile services, but fixed-line numbers under 45 are distinct and non-portable to mobile networks.

Caller Instructions

• Local callers: Always include the trunk prefix 0 when dialing from within Kenya. Omitting it may result in a failed call.
• International callers: Drop the leading zero and use +254 45. Ensure you have the correct international exit code for your country.

For emergency services or directory inquiries, always use the national emergency numbers (e.g., 999 or 112) rather than the area code.
