Quick Answer: Kwale Postal Code is 80400 for Ukunda (the largest town), while 80403 serves Kwale Town. Still, the County uses 12+ different postal codes across its 4 sub-counties for efficient mail delivery.
While many people make the mistake of using 80403 for all Kwale addresses, it only 80403 works for Kwale Town (the county capital), but then it doesn’t work efficiently for Ukunda, which is actually the county’s largest commercial center, using 80400, or in Diani Beach, where 80401 is relevant. Here’s everything you need to know about Kwale’s postal codes.

What Are Kwale Postal Codes?
Kwale Postal Code is 80400 for its G.P.O. located at Ukunda. The county uses the postal region prefix 80, which identifies it as part of the Coast postal region. The full postal code follows the complete Kenya Postal Code structure, which is usually a 5-digit number where the first two digits (80) represent the coastal region, and the remaining three digits identify the specific post office or delivery area.
For example, 80400 breaks down as:
- 80 = Coast region (Kwale County)
- 400 = Ukunda Post Office

How to Use Kwale 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 Mombasa County:
Standard P.O. Box Address Format
Correct format:
[Recipient Name]
P.O. Box [Number]-[Postal Code] [Town/Sub-County]
[KENYA]
Example 1: Ukunda Commercial Address
Jane Omondi
P.O. Box 234 – 80400, Ukunda
Kenya
Example 2: Diani Beach Hotel Address
Diani Sands Resort
P.O. Box 567 – 80401, Diani Beach
Kwale, Kenya
Example 3: Kwale Town Address
Peter Mwangi
P.O. Box 890
80403, Kwale
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 (234-80400 is the correct format, not 234 80400 ). 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 Kwale
The application process to get your own P.O. Box in Mombasa 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 Mombasa Postal offices, are done via the Posta Kenya Application Portal at: https://apps.posta.co.ke/boxupdate/
