What is a Latvian personas kods?

The personas kods is Latvia's 11-digit personal code issued by the PMLP. Codes issued before July 2017 encode the date of birth as DDMMYY in the first six digits and end with a mod-11 check digit. Codes issued since then start with 32 and carry no birth date.

How is the old check digit calculated?

Multiply the first ten digits by the weights 1, 6, 3, 7, 9, 10, 5, 8, 4, 2, sum the products, then compute C = (1101 − sum) mod 11 mod 10. That result must equal the eleventh digit for the code to be valid. This validator runs that exact calculation.

Why does my new 32-series code pass without a check digit?

Latvia removed birth-date semantics and the published checksum requirement for codes issued from July 2017. Such codes begin with 32, so the validator confirms the 32 prefix and 11-digit length but does not apply the old mod-11 formula, which does not apply to them.

Does a valid check digit prove the person exists?

No. A valid checksum only proves the code is internally consistent. It does not confirm the code was actually issued or belongs to a real person — only the PMLP register can confirm that. The tool performs no network lookup.

Is my data sent anywhere?

No. Every check runs locally in your browser with JavaScript and the personal code never leaves your device, which makes the tool safe for KYC and HR pre-screening.

Latvia Personas Kods Validator

The Latvian personas kods (personal code) is an 11-digit identifier from the PMLP. Codes issued before July 2017 embed the date of birth (DDMMYY) and end with a mod-11 check digit; codes issued since then begin with 32 and carry no date or published checksum. This tool validates both variants in your browser.

How it works

After removing the optional dash, the validator looks at the first two digits:

New 32-series code: if the code starts with 32, it is a post-2017 code with no birth date. The tool checks only that it is 11 digits beginning with 32.
Old date-based code: otherwise, the first six digits are treated as DDMMYY. The tool runs the official mod-11 check-digit algorithm:

weights = [1, 6, 3, 7, 9, 10, 5, 8, 4, 2]
sum     = Σ digit[i] × weights[i]   for i = 0..9
C       = (1101 − sum) mod 11 mod 10
valid   = C equals digit[10]

It also performs a light plausibility check on the embedded date (day 1–31, month 1–12) and reports it, though the checksum is the authoritative test.

Example

Old code:  161175-19997  →  date 16-11-1975, check digit recomputed and compared
New code:  32012-345678   →  begins with 32 → format-only validation, no check digit

Notes

A valid result confirms the code is internally consistent (old) or correctly structured (new). It does not confirm the code was issued or belongs to a real person — only the PMLP register can. All processing is local, so the tool is safe for KYC and HR pre-checks.
