Why these tools?
Developers often need batch, normalized, verifiable address data. We turned the common operations into free online tools, cross-linked with the generators.
Free Tools
Utilities that complement the address generators — free, no sign-up.
Address Formatter
Paste a raw address string; auto-detect the country (US, UK, Canada, Australia, Germany), parse street, city, state and postcode, and output a normalized two-line format.
ZIP & Postcode Database
Searchable postcode database for the US ZIP codes, UK postcodes, Canadian postal codes, Australian postcodes and German PLZ: browse cities by country and region.
Area Code Lookup
Look up telephone area codes for US states and Canadian provinces: reverse-search by area code, or browse codes per state/province.
US Tax-Free & Sales Tax Calculator
US sales tax calculator: pick a state and amount to estimate the state-level sales tax; the five tax-free states (AK/DE/MT/NH/OR) show $0 automatically.
