CNPJ registration status active closed suspended unfit
Before signing a contract or qualifying a company in a petition, the first filter is the CNPJ registration status. Not every company "found" in the Federal Revenue database is fit to contract, and the label shown in the result changes what you should do next.
Fictitious numbers used only to illustrate the calculation; querying each one separately returns the data for that specific establishment.
Fictitious example built with the same Federal Revenue algorithm, just to show that letters in the first 12 positions also pass validation.
A good starting point for due diligence, but it does not replace it: add specific compliance certificates before signing.
Before any lookup, the tool calculates the last two digits (check digits) from the first twelve, using a weighted algorithm with modulo 11. If the digits provided do not match the calculated ones, the CNPJ is treated as invalid and the query is not even sent. Validation accepts both the numeric CNPJ and the new alphanumeric CNPJ from the Federal Revenue Service (letters in the first 12 positions, check digits always numeric). Keep in mind that a formally valid CNPJ merely follows the mathematical rule of the digits, it does not mean the company exists, is active, or is trustworthy.
No. "ACTIVE" only indicates that the CNPJ was not closed, suspended or declared unfit with the Federal Revenue, the status describes the registration, not tax or labor compliance. For that, you need specific compliance certificates and, if the amount involved is significant, an accounting or legal review before contracting or signing.
Yes. Each establishment has its own CNPJ, sharing the headquarters' 8-digit root and varying only the next 4 digits (0001 for the headquarters, 0002 onward for each branch). To see the data for that specific unit, such as address and registration status, enter the branch's full CNPJ, not just the headquarters'.
No. Check-digit validation (modulo 11) only confirms that the number follows the CNPJ's mathematical construction rule, whether in the numeric or alphanumeric format. It does not guarantee that company exists in the Federal Revenue registry: only the actual database lookup that follows confirms that.
