Online ZIP Code Generator (CEP) - Free for Testing

Our free online zip code generator (cep) creates valid test data instantly. Designed for software developers, QA engineers, and testers, this tool generates mathematically valid data that passes all format and check-digit validations, making it perfect for populating test databases, filling out forms, and building automated test suites.

Key Features

  • Generates mathematically valid data instantly using official algorithms
  • Batch generation to create multiple entries at once for testing
  • Formatted and unformatted output options for different use cases
  • One-click clipboard copy for fast workflow integration
  • No registration, API key, or installation required
  • Completely free with unlimited usage

The generation algorithm follows the official specification, ensuring that every generated value passes standard validation checks. This makes the tool ideal for automated testing pipelines, form validation testing, and database seeding where realistic test data is needed without using real personal information.

All generation happens in your browser using JavaScript and no data is sent to any server. The tool is completely free, requires no registration, and works on any device including smartphones and tablets. Generated values are random and unique per session, providing fresh test data every time.

Frequently Asked Questions

What does CEP Generator do?
CEP Generator helps you generate CEP with a short, direct workflow. It is meant for people who need an answer quickly without losing the context behind the result.
When should I use CEP Generator?
Use CEP Generator when the priority is speed, repeatability and fewer manual steps. It works well for quick checks, operational routines and situations where you do not want to open a full application for a small task.
Does CEP Generator keep my data private?
For client-side tools, the main processing happens in the browser. That reduces friction for sensitive or temporary inputs and makes the page useful for quick private checks.
How is CEP Generator different from nearby tools?
CEP Generator focuses on one narrow job so the page stays fast and easier to trust. If your workflow continues after this step, CPF Validator — Official Algorithm is the kind of related tool you would use next.
Do the generated CEPs correspond to real addresses?
Not necessarily. The CEPs are within the valid range for each state but may not map to an actual street or neighborhood. They are intended for testing only.
What CEP range does each state use?
Each state has official ranges defined by Correios. For example: SP uses 01000-19999, RJ uses 20000-28999, MG uses 30000-39999, and so on.
Can I generate CEPs for a specific state?
Yes, select a state from the dropdown to generate CEPs only within that state's official range. Or choose "Any State" for random states.
