CEP Lookup (Brazilian ZIP)

CEP Lookup finds the full address behind any Brazilian postal code (CEP) in seconds. Enter the 8-digit CEP and the tool queries the free, public ViaCEP service to return the street, district, city, state and area code (DDD), then lets you copy a ready-to-use formatted address with one click. Your recent lookups are kept in the browser session so you can revisit them quickly. It is perfect for filling out forms, validating shipping addresses, or building and testing address features — and only the CEP you type is ever sent to the lookup service.

How to Use CEP Lookup

  1. Type an 8-digit CEP (for example 01001-000) and press Search or Enter.
  2. Read the street, district, city, state and DDD returned for that code.
  3. Copy the formatted address, or pick a previous CEP from your recent searches.

Benefits and Use Cases

  • Auto-fill or verify Brazilian addresses quickly for forms and checkouts.
  • Great for developers testing address lookups against real postal data.
  • Only the CEP is sent to the public ViaCEP API; nothing else leaves your browser.

FAQ

Where does the address data come from?

From the free public ViaCEP API maintained for Brazilian postal codes. Only the CEP you type is sent to it.

Why did my CEP return nothing?

The CEP may not exist or may not be registered yet. Double-check the 8 digits.

Is my search history stored?

Recent lookups are kept only in your browser session (sessionStorage) and are cleared when you close the tab.
