The Postcode/Address Validation plugin allows you to add address verification, auto-complete, or postcode lookup functions to your checkout process in your online shop. This in turn simplifies the process in addition to preventing customer’s to use invalid addresses. The plugin works together with a service that provide address or postcode lookup (for example Loqate, SmartyStreets, Postcode.nl, PostcodeSoftware.net, Crafty Clicks)
Loqate provides the address auto-complete for all around the world. A paid Loqate account is required to be able to have your customers auto-complete addresses in any country. SmartyStreet provides address verification for the US. It lets customers look up or verify an address, or accept recommended adjustments if necessary. Postcode.NL, PostcodeSoftware.net, and Crafty Clicks provides address lookup by postcode for UK or NL addresses.
