A Kenyan parcel can carry an old title number, a Registry Index Map number and a newer Ardhisasa parcel number, and the three don’t always look alike. They usually describe the same land. The Land Registration Act 2012 merged several old registration systems into one, and the numbering has been catching up since. Confirm that the numbers match before you buy, not after.
Before you start: write down the title number, the parcel number and the registration section from the seller’s paperwork. You will compare all three against Ardhisasa and the Registry Index Map.
The old numbering systems
Before 2012, Kenya registered land under four statutes: the Government Lands Act, the Registration of Titles Act, the Land Titles Act and the Registered Land Act. Each had its own numbering. Land under the Registered Land Act, mostly agricultural and adjudicated land, used a Registration Section/Block/Parcel format such as Kajiado/Kaputiei North/1245. Land under the Government Lands Act or the Registration of Titles Act more often used a Land Reference (L.R.) number.
What the Land Registration Act 2012 changed
The 2012 Act repealed those four statutes and created one land register. Conversion lists, prepared alongside the Registry Index Maps, show old and new parcel numbers side by side. The renumbering is administrative. It does not change who owns the land, its acreage or its boundaries. If you haven’t converted an old title, the Registrar can do it without your application, using Form LRA 97 to issue the new title and cancel the old one.
Title number vs the Ardhisasa parcel number
Ardhisasa, Kenya’s digital land registry, identifies parcels in the same County or District/Block or Section/Parcel format, for example Nairobi/Block82/123. You can search by title number, Land Reference number, plot number or registration section. The system notifies the registered owner, who must approve your request before you receive the digitally signed result. The fee is KSh 1,000 per search, according to the Ministry of Lands.
Ardhisasa’s coverage is not complete. As of October 2026 the State Department for Lands lists Nairobi, Murang’a, Isiolo and Mombasa Island, with Mombasa moving over section by section and more areas to follow. If your area isn’t on it yet, search at the physical registry.
Why the numbers sometimes don’t match
A mismatch between an old title, Ardhisasa and a deed plan or RIM usually has one of three causes:
- The parcel was subdivided or amalgamated after the title was issued, which created new sub-parcel numbers.
- The parcel was converted from an old-regime number to the block system, but the seller’s paperwork was never updated.
- The owner never completed the digital conversion, so Ardhisasa shows an incomplete record.
None of these means fraud on its own. You should still get a clear explanation, and the block name, parcel number and registration district should match exactly across the title, the survey or RIM documents, and Ardhisasa.
How to verify a parcel number before you buy
- Run an Ardhisasa search by title or parcel number and wait for the owner-approved result.
- Get a certified Registry Index Map or survey plan directly from the Survey of Kenya, never from the seller, and check that the block, parcel and district fields match.
- Have a licensed surveyor confirm the beacons on the ground match the mapped parcel.
- Check that neighboring parcel numbers on the RIM run in sequence. A gap in the sequence can signal a problem.
Ardhisasa shows the current state of the register. It does not show the full history of past transfers or allocation letters. For land with a complicated history, add a physical registry or gazette check.
Watch out for: a parcel number that matches on paper but not on the ground
A break in the neighboring parcel sequence on the Registry Index Map, or a title number that Ardhisasa cannot find, needs a documented explanation before you pay anything.
Frequently asked questions
My seller’s title number doesn’t match Ardhisasa. Is that a scam?
Often it isn’t. An incomplete conversion or an old subdivision is the usual reason. Get a documented explanation and confirm it with a Survey of Kenya extract before you go further. Don’t take the seller’s word for it.
Is the old title number still valid?
Yes, until it is formally converted and cancelled under the 2012 Act. Relying on it for searches and transactions is getting harder as more registries move onto Ardhisasa.
What’s the difference between a title number and a parcel number?
People use the two interchangeably. Strictly, the parcel number is the Section/Block/Parcel identifier used on the RIM and Ardhisasa. The title number is whatever identifier is printed on the title document you hold, which may be the old number or the converted one.
