Uasin Gishu Postal Codes – Official Post Offices & Areas

Quick Answer: Uasin Gishu County’s Main Postal code is 30100 for Eldoret Town. However, the county uses 20+ different postal codes across its 6 sub-counties, including: Ainabkoi (30101), Burnt Forest (30102), Kipkabus (30103), Moiben (30104), Soy (30105), Turbo (30106), and Moi University (30107).

Uasin Gishu County is located in the Rift Valley region, approximately 310 kilometers northwest of Nairobi. It is also known as the “Home of Champions” due to its production of world-class athletes. Many people make the mistake of using 30100 for all Uasin Gishu addresses, but that’s not the case at all. While 30100 works for Eldoret Town itself, it won’t suffice for other areas like Ainabkoi, Moiben, or Turbo. The county is divided into 6 sub-counties (Kapseret, Ainabkoi, Kesses, Moiben, Soy, and Turbo), each with different postal codes.

What Are Uasin Gishu Postal Codes?

Uasin Gishu Postal Code is 30100. It uses the postal region prefix 30, which identifies it as part of the Rift Valley region managed by Posta Kenya. This differs from Nairobi’s 00 prefix or Mombasa’s 80 prefix. The format follows Kenya’s standard five-digit structure: the first two digits (30) represent the broader Rift Valley region, while the final three digits pinpoint the specific post office or delivery zone.

For example, 30100 breaks down as:

• 30 = Rift Valley region (Uasin Gishu County)
• 100 = Eldoret Town GPO (General Post Office)

How to Use Uasin Gishu Postal Codes Correctly

Postal codes are essential for the sorting and delivery of mail on time, but also knowing how to use them correctly will facilitate such a process even more. Just like how you write and format the Nairobi Postal address, the same format is applied when addressing mail in Uasin Gishu County:

Here is the Standard P.O. Box Address Format:

[Recipient Name]

P.O. Box [Number]-[Postal Code] [Town/Sub-County]

[KENYA]

Example 1: Eldoret Address

John Kipchoge

P.O. Box 1234-30100, Eldoret

Kenya

Example 2: Moiben Address

ABC Farmers Ltd.

P.O. Box 5678-30104, Moiben

Uasin Gishu, Kenya

Example 3: Moi University Address

Mary Chepkoech

P.O. Box 9012-30107, Moi University

Eldoret, Kenya

Where To Pay Attention: Always include the recipient’s full name on the first line. The hyphen between the box number and the postal code is mandatory (1234-30100 is the correct format, not 1234 30100). Include the town/sub-county name after the postal code for clarity. Add “KENYA” on the last line for international mail.

How to Apply for a P.O. Box in Uasin Gishu

The application process to get your own P.O. Box in Uasin Gishu is an easy process, thanks to changes that Posta Kenya has made in the previous years. The application process is now entirely online, whereby you can complete everything from your phone or computer. Before you apply for one, you need to understand that Posta Kenya offers two types of P.O. Boxes, and your choice affects costs, collection methods, and what you can use the address for.

First, there is the Physical P.O. Box (Traditional Metal Box), where, if you apply for one, you get physical keys, a designated box number, and a secure slot at your chosen post office. Lastly, there’s the Virtual P.O. Box (MPost) whereby your phone number becomes your postal address. Upon applying, you don’t get a physical box or keys; instead, you get just SMS alerts when mail arrives, and then you visit your chosen post office with your ID to collect.

All Postal Box Applications in Kenya, including for Uasin Gishu Postal offices, are done via the Posta Kenya Application Portal at: https://apps.posta.co.ke/boxupdate/ for 30100 for Eldoret, 30101 for Ainabkoi, 30104 for Moiben, etc.
