Implementation and validation notes
Brazilian CEP codes contain eight digits shown 5-3 with a hyphen. The code is written before locality and state details in many address layouts.
Validate required state, character set, length, and syntax on the client, then repeat validation on the server. Preserve the original input and normalize into a separate field; never truncate local scripts, compound names, or leading zeroes to fit a single Western assumption.
This guide describes common formats rather than an official registry and cannot enumerate every exception. Generated output is for testing only, not delivery, calling, identity verification, or real account activity.

Frequently asked questions
What is the standard Brazil postal code format?
A common representation is NNNNN-NNN, for example 01310-100. Brazilian CEP codes contain eight digits shown 5-3 with a hyphen. The code is written before locality and state details in many address layouts.
How should Brazil postal code test data be stored?
Store the original value as a string so leading zeroes, spaces, hyphens, accents, and local scripts are preserved. Use a separate normalized field for search.
Does correct formatting prove the data is real?
No. Syntax validation cannot prove an address is deliverable, a number is assigned, or a name belongs to a real person.
