The Brazilian postcode is named CEP. It is an hierarchical code with 8 digits. The partial 5-digit CEP have map and polygonal representation, but full 8-digit CEP not (it is used today as a logistic non-spatial information), is only a street segment attribute.

Individual CEPs are supplied free, but a full-copy of all CEPs aren't free (not available in bulk)... The access to database queries is free as Internet-webservice: CEP-to-address, and address-to-CEP, human and machine resolution services... So this is a cause of ambiguity in this form: CEP is individually free, but must pay to access on bulk.

The CEP, as a postcode-list, is copyrighted and sold by the public company "Empresa Brasileira de Correios e Telégrafos - Correios" (Brazilian mail service). It is a non-spatial database, with no coordinates in the dataset:

The postcode copyright monopoly by Correios company exist since 1978, with the Federal Law 6538.
