FAQ
Common questions
Is the Puerto Rico business search free?
Yes. It is free to try with no account and no API key. Search is free on the API too and is never billed.
Can I search by entity number?
Yes. Pass the state's file or entity number for an exact match, or search by business name to get ranked candidates with number, status, and address.
What if my business is registered in another state?
A company registered elsewhere is in another register and will not appear. Pick that state, or use the full company search to choose the right register.
