Address completion (Addressy)

Postcode / Address Validation works by connecting your store to a service that provides address or postcode lookup. You can use Addressy, SmartyStreets,, PCA Predict,, or Crafty Clicks.

Address Auto-Completion

Address auto-complete is available with Addressy, which works for merchants in any country. 100 US address lookups are available for free each month (including address classification as ‘residential’ or ‘commercial’), but a paid Addressy account will allow your customers to auto-complete addresses in any country.

Merchants in any country can sign up for an Addressy account to get started.

See Addressy + WooCommerce in action.

Address Verification

US address verification uses SmartyStreets, which lets customers look up or verify an address, or accept recommended adjustments as needed. 250 lookups per month are available for free, and additional lookups can be purchased. SmartyStreets can also classify addresses (residential or commercial) or geocode them.

SmartyStreets is for US merchants / US address verification only.

See SmartyStreets + WooCommerce in action.

Postcode Lookup

Address lookup by postcode is available for UK or NL addresses via one of the following providers: Postcode.NL, PCA Predict,, or Crafty Clicks.

PCA Predict,, and Crafty Clicks use data from Royal Mail to perform UK address lookups based on postcode, so you can be assured of address data accuracy. You’ll need a low-cost plan with any of these providers to perform UK postcode lookups.

Merchants who’d like to offer postcode lookup in the Netherlands can use Postcode.NL to provide postcode lookup for Dutch addresses.
