Shape, check digit, accepted and refused examples and the API call for Company code in Lithuania. Every example on this page is run through the same validators as the free identifier validator, so a value shown as accepted is a value the validator accepts.
| Field | Value |
|---|---|
| Register | JAR (Registrų centras) |
| Shape | N{8} C |
| Check digit | Enforced. Weights 1 to 8 over the first 8 digits, sum mod 11; when that is 10 the weights 3,4,5,6,7,8,9,1 are used, and a second 10 reads as 0. |
| Worked example (accepted) | 110053842 |
| Normalised form | 110053842 |
| A one-character slip | 110053843 is refused |
| Regex (normalised form) | ^[0-9]{9}$ |
| API call | GET /companies/search?country=LT&company_number=110053842 |
| VAT number | LT + 9 or 12 digits (State Tax Inspectorate list) — published or confirmed by the register |
LT in front is a VAT number, not the company code, and is refused. Sole proprietorships and partnerships are never served.

Shape notation: N digit · L letter · X digit or letter · C check digit or character · {n} repeat n times.
A valid shape and check digit prove that a number is well-formed, not that a company holds it. Only a lookup in the register answers that.
