About
What this site is
US Tax-Free State Address Generator (usaddregen.com) is a free, browser-based tool that produces realistic-format random US addresses limited to the five states with no statewide sales tax:
- Delaware — no sales tax since statehood; Gross Receipts Tax instead.
- Montana — no general sales tax; targeted resort taxes in a few towns.
- New Hampshire — no general sales tax, no wage income tax.
- Oregon — nine ballot rejections of a sales tax; Corporate Activity Tax on businesses.
- Alaska — no statewide sales tax, but borough-level local sales taxes apply.
Each generated address combines a real US city, a real ZIP code that belongs to that city in the USPS database, a synthetic street, a synthetic full name, and a phone number using an area code that genuinely covers the chosen state.
Why this niche, instead of a generic 50-state generator
A lot of online address generators sample addresses across all 50 US states. That is useful when you genuinely need a random US address, but it makes a specific kind of test fixture harder: the case where the destination should produce a $0.00 sales-tax line.
Modern e-commerce checkout code goes through a lot of paths to get sales tax right. The tax engine is queried, the cart math adjusts, the invoice template renders, and the order confirmation email shows the breakdown. Each of these steps has its own bug surface for the zero-tax case — missing line items, hidden rows, wrong subtotals, misformatted localization. A dedicated tax-free state generator is the cleanest way to produce that test fixture quickly.
Limiting the dataset to five states also has practical engineering benefits:
- The whole JSON 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 Workers 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 5 states × 5 cities, with ZIP codes and area codes.
- 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 on X (Twitter): @ailenswpu. DMs are open for feedback, bug reports, and feature requests. 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.
- Translation polish for the Simplified or Traditional Chinese UI.
