Because of the way the Post Code Address Database is licensed in the UK by Royal Mail, Postcode Anywhere was set up to offer pay as you go post code lookups.
Viper Cart is pre-integrated with Postcode Anywhere meaning all you have to do to get it up and running is sign up for an account with them, purchase some credits and then enter your account details into the administration area of Viper Cart.
After it has been set up, your customers will be able to simply enter their postcode, click Auto Complete and then choose from a list of addresses for that postcode. Their address will then be automatically filled in saving them the time of typing it manually.
