What is the format of a KRA PIN?

A KRA PIN is 11 characters: a leading letter, then nine digits, then a trailing letter. The leading letter is A for individuals and P for non-individuals such as companies, partnerships, and trusts.

Does this tool confirm the PIN is registered?

No. KRA does not publish a public check-digit algorithm, so this tool validates the structure only — the prefix, the nine digits, and the trailing letter. To confirm a PIN is active, use the official KRA iTax PIN checker. This tool performs no online lookup.

What does the leading letter mean?

The first letter classifies the taxpayer: A marks an individual person, while P marks a non-individual such as a company, partnership, trust, club, or society.

Why is the last character a letter?

The trailing letter is a control character KRA assigns when the PIN is issued. Because the exact algorithm is not public, the validator only confirms that a letter is present in that position, not that it is the correct control letter.

Is my PIN sent anywhere?

No. The whole validation runs in your browser using JavaScript. The KRA PIN never leaves your device, so it is safe for confidential records.

Kenya KRA PIN Validator

A KRA PIN is the Personal Identification Number issued by the Kenya Revenue Authority for tax registration. It appears on invoices, tenders, and compliance documents across Kenya. This free validator checks that a PIN is well-formed and tells you whether it belongs to an individual or a non-individual, all in your browser.

How it works

A KRA PIN is exactly 11 characters in the pattern letter + 9 digits + letter:

Prefix letter. Must be a letter. A marks an individual; P marks a non-individual entity (company, partnership, trust, society). Other prefixes are flagged as unrecognised.
Body. The middle nine characters must all be digits.
Suffix letter. The final character must be a letter — the control character KRA assigns at issue.

Because KRA does not publish the check-letter algorithm, this is a structural validation: it confirms the layout and the prefix meaning, not that the trailing letter is the correct control value.

Example

Take A012345678Z. The prefix A marks an individual, the body 012345678 is nine digits, and the suffix Z is a letter, so the structure is valid and the PIN belongs to an individual.

A PIN like P051234567K is also structurally valid, and the P prefix tells you it belongs to a non-individual entity such as a company.

Notes

A structurally valid PIN is not proof of registration — only the KRA iTax PIN checker can confirm that a PIN is active. Everything here runs locally, so your KRA PIN never leaves your device.
