Shape, check digit, accepted and refused examples and the API call for NIT in Colombia. 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.

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.
