What does a Uganda NIN encode?

The NIRA NIN is 14 alphanumeric characters. By documented convention the first character is the applicant class (C = citizen), the second is the gender code (M or F), the third and fourth are the last two digits of the year of birth, and the remainder is a NIRA-assigned serial.

Why is the serial not verified?

NIRA does not publish a check-digit algorithm, so this tool validates the 14-character alphanumeric format and the documented class, gender and birth-year prefix but cannot verify the serial.

Is my NIN sent anywhere?

No. The validator is privacy-first. All processing happens locally in your browser with no network requests — your NIN never leaves your device and is never checked against the NIRA database.

Uganda NIN Validator & Decoder — Class, Gender & Birth Year

Uganda NIN validator

Validate a Ugandan NIN (National Identification Number) and decode the parts that follow a documented convention. The NIRA NIN is 14 alphanumeric characters: the first character is the applicant class (C = Ugandan citizen), the second is the gender code (M/F), the third and fourth are the last two digits of the year of birth, and the rest is a NIRA-assigned serial.

NIRA does not publish a check-digit algorithm, so the deterministic offline checks are the 14-character alphanumeric format and the recognised class/gender prefix.

Privacy-first: everything runs in your browser with no network requests. This tool decodes the structure only — it cannot confirm a NIN against the NIRA database.
