Postal Code Lookup
Queried against public databases — none of your data is stored.
- Type the postal code. Punctuation is optional.
- The result returns the matching address details: street, district, city and state.
- The tool recognises the Brazilian eight-digit format and the US five-digit one.
A US ZIP code is not a geographic area in the way most people assume — it is a delivery route. That is why ZIP boundaries do not align with city or county lines and can be oddly shaped.
The first digit covers a group of states, the next two narrow to a sectional centre facility, and the last two identify the delivery area served by that facility.
Some ZIP codes serve a single building with high mail volume, and others cover no residential area at all, existing only for post office boxes.
- A recently created code not yet reflected in the queried database.
- A code assigned exclusively to an organisation, which may not appear in public data.
- A typo — most five- or eight-digit combinations are not valid postal codes.
- A new development whose addressing has not been formalised.
The lookup uses a public addressing database. It reflects the official record but can lag very recent changes.
The result gives the address, never the occupant. No name, phone or personal data is attached — postal codes identify locations, not people.
For formal mailing requirements, confirm with the official postal service.
Frequently asked questions
Because a ZIP code is a delivery route, not a geographic region. It follows how mail is carried, which is why it does not align with city or county lines.
No. Postal codes identify locations, not people. No personal data is returned or queried.
Check the typing first. If correct, it may be recently created, assigned exclusively to an organisation, or part of a development whose addressing is not yet formalised.
Yes. The tool recognises the eight-digit format and returns street, district, city and state.
No. The lookup happens on demand and nothing is logged.
