CEP Lookup

Query public information for a CEP from different services.

ℹ️ How it Works

This tool allows you to query public data for a Brazilian CEP (Postal Address Code) using different publicly available APIs. The number is cleaned (removing non-digit characters) before the query to ensure it is sent in the correct format to the providers.

  • Brasil API: A free and open API that consolidates various Brazilian public data.
  • Republica Virtual: One of the oldest and most traditional CEP query services.

  • API CEP: A simple and fast API for CEP lookup, with data served via CDN.
