New Hampshire Address Generator

State code: NH · ZIP prefix: 03 · Area code: 603 · Statewide sales tax: 0%

New Hampshire’s state motto, Live Free or Die, comes with a fiscal translation: no general sales tax, and no income tax on wages. That makes NH a popular edge case for e-commerce checkout flows and tax-engine integration tests — you need addresses that should produce a $0.00 tax line, with a real-looking 03xxx ZIP code and the statewide 603 area code on the phone field. That is what this generator does.

New Hampshire tax background

New Hampshire has no general sales tax and no tax on earned wages. The state historically levied an Interest & Dividends Tax (I&D Tax) on investment income, but that was fully phased out by 2025. NH funds itself through a relatively high property tax, a Business Profits Tax, a Business Enterprise Tax, and a few targeted excise taxes.

Two important targeted taxes still apply at the register, even though there is no general sales tax:

For ordinary online retail shipped to an NH address, neither applies. New Hampshire residents are famously known for driving across the border into Massachusetts for the higher income but for shopping in their own state to avoid MA’s 6.25 % sales tax — a real-world example of the kind of cross-border behavior that checkout analytics teams sometimes need to model.

Common use cases

Important caveats

Street numbers and street names are synthetic. The address will not pass real USPS deliverability checks, Smarty / Lob validation, or payment-gateway AVS — that is the intended behavior of a test data generator. See our AVS & ZIP validation explainer for the full background.
