About the State Registration Generator

What is the State Registration (Inscricao Estadual)?

The State Registration (IE - Inscricao Estadual) is the taxpayer's registration in the ICMS registry, maintained by each state's Finance Secretariat. Each of Brazil's 27 states has its own format and validation algorithm.

What is this generator for?

Developers working with tax systems, electronic invoices (NF-e), and business registrations need valid state registrations for testing. This generator creates numbers according to the official algorithm of each state.

How does it work?

Select the desired state and the generator applies the specific algorithm for that state to generate a number with valid check digits. Each state has different weights, moduli, and formats.
