About
What this site is
US Address Generator (usaddregen.com) is a free, browser-based tool that produces realistic-format random addresses for all 50 US states plus country-specific international datasets:
- US state generators — all 50 states with city, ZIP code, area-code, and statewide sales-tax notes.
- International generators — country-specific city, region, postal-code, and phone-number formats for markets such as India, Philippines, Indonesia, Brazil, Mexico, United Kingdom, Canada, Australia, Nigeria, Egypt, Turkey, and Pakistan.
- No-sales-tax state reference — Delaware, Montana, New Hampshire, Oregon, and Alaska remain highlighted for checkout and tax-engine testing.
Each generated address combines a real city/region/postal-code combination from the static dataset, a synthetic street, a synthetic full name, and a phone number formatted for the selected state or country.
Why this dataset exists
A lot of address generators return plausible-looking records without explaining what fields are paired together. This project keeps the dataset static and audit-friendly so a developer can inspect the exact city, ZIP/postal code, area code, and sales-tax notes behind the generated fixture.
The no-sales-tax states still matter for e-commerce checkout testing because the zero-tax case can expose missing line items, hidden rows, wrong subtotals, or misformatted localization. The broader 50-state and international coverage makes the same tool useful for signup forms, CRM demos, localization checks, and seed records.
Keeping the dataset static has practical engineering benefits:
- The dataset fits in the static HTML/JS bundle; no API call required.
- The output is deterministic enough to audit by hand if you suspect a bug.
- The site loads quickly on Cloudflare’s global edge with no backend.
How it’s built
The site is a small Vite static project hosted on Cloudflare Pages / Cloudflare static assets. There is no database, no user account system, and no backend address-generation API. Everything runs in your browser:
- A small in-memory dataset of 50 US states with ZIP codes, area codes, and sales-tax notes.
- Country-specific international datasets for common form-testing markets.
- Random street numbers and names assembled from a fixed wordlist.
- A multilingual UI (English, Simplified Chinese, Traditional Chinese) controlled by a single dropdown, with the language preference syncing via URL parameter and localStorage.
Source-level signals (Schema.org JSON-LD, hreflang, an llms.txt for LLM crawlers, an ads.txt for the advertising network) are all in place because we wanted the site to be as legible as possible to both traditional search engines and the newer generative search engines.
What this site is not
We want to be honest about the boundaries of the tool.
- Not a real-address service. The output looks realistic, but the street line is synthetic; it will not pass any real address-verification check (USPS, Smarty, Lob, AVS).
- Not tax advice. “Tax-free state” here just means “no statewide sales tax.” Other taxes, local sales taxes (most notably in Alaska), and business-level taxes still exist. For tax decisions, talk to a professional.
- Not for fraud or identity claims. The Terms of Use, and the visible footer note on every page, make clear that the generator is for legitimate testing, design, and demo work. Anything else is on the user, not the tool.

Contact & source code
The fastest way to reach the maintainer is by email at support@usaddregen.com, or on X (Twitter): @ailenswpu. Feedback, bug reports, and feature requests welcome. Prefer code-style feedback? The site is open-source on GitHub: Ailenswpu/usaddregen — issues and pull requests welcome. We particularly like:
- Pointing out a city/ZIP combination that the generator gets wrong.
- Suggesting a new test scenario the tool could support without breaking its deliberately small scope.
- Suggesting an international city/postal-code pair that should be added to a country dataset.
- Translation polish for the Simplified or Traditional Chinese UI.
