Only works for Companies

The register on https://search.cac.gov.ng uses numbers not uniquely. Normal companies are RC-1234567, but other legal types us3 other formats like like "Incorporated Trustees" IT-1234567 or "Limited partnerships" LP-1234567... Hence, I would propose to include the XX- at the beginning, into the identifier. Newt713 (talk) 17:29, 1 January 2024 (UTC)
