Shape, check digit, accepted and refused examples and the API call for State + register number in United States. 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 | State registers, SEC (CIK), GLEIF (LEI) |
| Shape | SS-X{1,40} | CIK-N{10} | LEI-X{20} |
| Check digit | None: the shape is the only test. No check digit anywhere: the state code and register number, CIK- and up to 10 digits (an SEC filer), or LEI- and 20 characters. The shape is the only test. |
| Worked example (accepted) | NY-4424185 |
| Normalised form | NY-4424185 |
| Also accepted as input | ny 4424185 · CIK-0000320193 |
| Regex (normalised form) | ^([A-Z]{2}-[0-9A-Za-z][0-9A-Za-z./-]{0,39}|CIK-[0-9]{10}|LEI-[0-9A-Z]{20})$ |
| API call | GET /companies/search?country=US&company_number=NY-4424185 |
| VAT number | The register data holds no VAT number for this identifier. |
Register numbers repeat across states, so the state prefix is part of the identifier. The API serves a defined set of state registers plus SEC filers and LEI holders, not every US company.

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.
