Useful to know
What is Murang'a postal code?
The Muranga post-office branch is listed as 10200 in Posta's July 2025 branch list (source row 12, PDF page 10). Murang'a County contains other branches with different codes, so check the branch used for your address.
What is Oyugis postal code?
The Oyugis post-office branch is listed as 40222 in Posta's July 2025 branch list (source row 170, PDF page 14), with the source county shown as Homa Bay. Search Oyugis to inspect that record and its source edition.
Can I use this as a Kenya ZIP code finder?
If a form asks for a ZIP or postal code, use this finder to check the relevant Kenyan post-office branch. It searches the dated Kenya branch list, not worldwide ZIP codes, and it does not assign a code from your street or current location.
Why does a printed code differ from the five-digit display?
Some rows print a short numeric value such as 621. The display pads it on the left to 00621 and retains the original printed value in the detail and export. Import CSV code columns as text.
Does a result guarantee delivery or an open branch?
No. It reflects the July 2025 branch list. Confirm current service, a P.O. Box address and any delivery requirements with Posta.
Why are some counties unresolved?
Two rows contain MARAFA or MWINGI in the source county column. These are not county names. The original value is shown, and a county is not guessed from the branch name.
