How to find out the state registration of a CNPJ or CPF


The State Registration is the registration that the company needs to collect the Tax on Circulation of Goods and Services (ICMS). It is mandatory for companies in the areas of industry, commerce, transport, services and other activities that involve the sale, transport or storage of physical products.

The registration is similar to the CNPJ, but, as it is a state responsibility, it has rules and requirements that vary depending on where the company’s headquarters are. Subject to the specifics of each state, however, the Registration number will always consist of nine digits, of which the first two indicate the federative unit.
