My counter check with my address serves as proof of residence, why do I need to do the consolation registration?

Thanks, but then my check serves as proof of address

The main purposes of consular registration are as follows: - In cases of emergency, facilitate the Consulate General to contact Brazilians and their families in Brazil and / or vice versa; - Enable the Consulate to better understand the community to which it should assist; - Work as an auxiliary identification document for issuing a new travel document in cases of theft, theft or loss of passport or identity card. It is important to clarify that the consular registration card is not a driver's license, nor is it proof of regular immigration status. The consular registration card only proves that the holder is residing in the USA and is registered with one of the consular offices of the Brazilian government.
