RG
and civil identification in Brazil
Learn when a foreigner uses RG, CRNM, passport, or CIN and how to avoid confusion between identity documents.
What to do, step by step
-
Check whether the service accepts a passport, CRNM, CIN, or another valid identity document.
-
Foreign residents usually use CRNM; some states may issue civil identification in specific situations.
-
Keep CPF and personal data consistent across documents to avoid refusals by banks, schools, and contracts.
-
Consult the state identification authority about requirements, appointments, and accepted documents.
-
If name or parentage differs, first correct the registration with the authority that created the error.
Frequently asked questions
Does a foreigner need a Brazilian RG?
Not always. For many purposes, a passport and CRNM work as identification. The requirement depends on the authority, state, and registration situation.
Are RG, CIN, and CRNM the same?
No. RG and CIN are civil identity documents; CRNM is a foreigner immigration registration. The accepted document varies by service.
Why was my document refused?
Refusals often happen due to outdated records, name mismatch, expired document, or internal service rules. Ask for the rule in writing and consult the official authority.
