Quick examples
What a CEP can tell you
A CEP is a Brazilian postal code. This lookup can return the CEP, state, city, district, street, and the service that supplied the reference. It organises a postal location; it does not identify a person, a precise residence, or delivery availability.
- 01001000 is a valid example for inspecting the JSON structure.
- State and city help confirm whether the result matches the expected area.
- Street and district can be absent or have different scope depending on the postal code and source.
How to send and check a lookup
Enter the eight CEP digits only. Once a response arrives, compare its city and state with the information already available, and keep the address complement separate. This prevents accepting an address merely because the code produced a response.
- Remove spaces, dots, and extra characters before building the request.
- Validate the format before calling the API and handle an error without clearing typed data.
- Let the user correct street, number, district, and complement.
Where it helps and where it is not enough
The route is useful for forms, record normalisation, data comparison, and Brazilian address prefill. It is not a substitute for delivery validation, precise geocoding, proof of occupancy, or confirmation for legal and financial purposes.
- Use the response as a fill suggestion, not as proof of residence.
- Do not infer a flat, house number, or person from a CEP.
- For critical flows, keep manual confirmation and consult the source documentation.
