Shape, check digit, accepted and refused examples and the API call for LEI in Germany. 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.

German company records are LEI-registered entities (GLEIF) and companies from the energy market register, not an extract of the Handelsregister. A company of the energy market register is numbered by its commercial-register entry, for example HRB12653/FRANKFURT-AM-MAIN (searched with register_number), declared by the operators and not checked against the register.

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.
