Supported Address Generators
The working release supports the United States and Australia. California and Oregon have focused state pages backed by the US dataset; Australia uses its own matched locality, region and postcode data.
How It Works
- Choose a supported generator. Each result starts from one complete postal row, so related locality, region and postal fields stay together.
- Generate a synthetic street. A fictional house number and street line are combined with that geographic record.
- Copy the result. Use the multiline address in a form, fixture, prototype or non-production test environment.
Real Geography, Synthetic Street
Matched geographic data
US city, state, ZIP code and county fields stay together. Australian locality, state or territory, and four-digit postcode fields also stay together rather than being assembled from unrelated lists.
Fictional street data
House number and street name are generated for testing. A random result may still coincidentally resemble a real address.
Results are not verified by USPS or Australia Post, guaranteed deliverable or valid as proof of residence.
Common Uses
- Testing address forms and validation messages.
- Creating development fixtures and seed records.
- Checking responsive layouts with realistic field lengths.
- Preparing prototypes, demos and QA scenarios.
Do not use generated output for mail delivery, identity verification, impersonation, KYC bypass or false proof of residence.
Data Source
US and Australian geographic relationships are built from the corresponding GeoNames postal-code exports under CC BY 4.0. Packaged browser datasets contain only the fields needed by each generator and omit coordinates and other unused source fields.
