What Are Taita Taveta Postal Codes?
Taita Taveta Postal Code is 80300 for its G.P.O at Voi Town. The county uses the postal region prefix 80, which identifies it as part of the Coast postal region managed by the Postal Corporation of Kenya, popularly known as Posta Kenya. This differs from Nairobi’s 00 prefix, Nakuru’s 20 prefix, or Eldoret’s 30 prefix. The format follows Kenya’s postal Code structure, which is usually a standard five-digit structure: the first two digits (80) represent the broader region, while the final three digits pinpoint the specific post office or delivery zone.
For example, 80300 is the main Voi G.P.O. code, which can be broken down as:
- 80 = Coast region (Taita Taveta County)
- 300 = Voi Town GPO (General Post Office)

How to Use Taita Taveta 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 Taita Taveta County:
Standard P.O. Box Address Format
Correct format:
[Recipient Name]
P.O. Box [Number]-[Postal Code] [Town/Sub-County]
[KENYA]
Example 1 (Voi Town):
John Kimani
P.O. Box 234-80300 Voi
KENYA
Example 2 (Wundanyi):

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 (234-80300 is the correct format, not 234 80300). Include the town/sub-county name after the postal code for clarity. Add “KENYA” on the last line for international mail.
How to Rent a P.O. Box in Taita Taveta
The application process to get your own P.O. Box in Taita Taveta 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.
