About this dataset
Kenya (KE) — internal licensing notes
Source research, 2026-09-03 — tier-1 check done, real lead unresolved
Checked Posta Kenya first. Found a real lead: openAFRICA hosts a
"Post Office and Post Office Code Locator" dataset described as sourced
from Posta Kenya. Could not independently verify licence, schema, or row
count — open.africa's API (api/3/action/package_show) returned a
Cloudflare bot-challenge page ("Just a moment…") to both curl and
WebFetch from this build environment, not the underlying JSON. Disclosed
as a real, unresolved lead (not ruled out on data-quality grounds), worth
a follow-up from an environment that can pass the challenge.
The source used instead — GeoNames KE
https://download.geonames.org/export/zip/KE.zip # 890 rows
Licence CC-BY-4.0, verified against export/zip/readme.txt on
2026-09-03 — Kenya carries no per-country caveat.
Verified directly against the raw source file:
admin_name1/admin_code1— County, 47/47 covered (Kenya's full post-2010-constitution county count). GeoNames' own numbering is alphabetical-with-an-outlier (Nairobi coded "05", everything else "10"-"55" alphabetically) and does not match the real ISO order at all (verified against Wikipedia's ISO_3166-2:KE page 2026-09-03) — a 47-entry name-based crosswalk was built and verified, not a numeric prepend or offset guess.- No admin2/admin3 tier — this source (post office locations only) reaches county level.
- 0 exact duplicate rows, 0 (postal_code, place_name) collisions, 0
literal
"nan"strings.

Proposed tier
B ($49). Small but complete (47/47 counties), real crosswalk verification work (Nairobi's out-of-sequence code would have broken a naive offset-based mapping).
