Fast, accurate & user-friendly address search
Swiftcomplete's address autocomplete API is the best way to add an accurate mailing address lookup to your website form, checkout or application.
Rather than having to type out the whole address by hand, our address search instantly suggests relevant addresses as you begin typing, matching every keystroke in real-time against the most accurate postal address databases.
Using address autocomplete reduces the time it takes to enter a fully verified address by up to 80% - great for improving checkout conversion rates, and eliminating typos and mistakes.
Address autocomplete features
Autofill an address from a postcode
Start searching by the postcode or any part of the address, and receive address suggestions in the correct local postal format.
Fuzzy address matching increases match rates by handling typos, abbreviations, missing words and accented characters.
Find results faster with location biasing
Location biasing reduces the number of keystrokes required to find an address by up to 75%, by automatically prioritising addresses near your current location (determined by your IP address).
Ecommerce sites and high street stores can preset bias location(s) towards their most popular delivery areas, and for even greater accuracy, users can share their current location to find addresses in a couple of keystrokes.
