Zipcode Generator
The Qodex Zipcode Generator is a fast and reliable tool for generating dummy U.S. ZIP codes that look real and meet standard formatting criteria. Whether you’re testing shipping flows, signup forms, or validating address-related input fields, this tool helps you avoid using real postal data while ensuring functional accuracy during development.
What is a ZIP Code?
The Qodex Zipcode Generator is a simple, reliable tool that creates valid-format 5-digit U.S. ZIP codes. Designed for developers, QA testers, and UI designers, it’s perfect for building and validating forms that include address inputs.
This tool outputs random ZIP codes that follow U.S. postal formatting rules—but without linking to actual residents or revealing real personal data.
You can use it alongside tools like the Address Generator, Username Generator, or Domain Name Generator to create full user profiles for mock signups, location-based testing, or geolocation interfaces.
