Fetchify Address Lookup od Fetchify (previously Crafty Clicks)

This browser extension from Fetchify (previously Crafty Clicks) can be configured to provide 2 different address lookup and validation products.
It adds address search functionality to systems where integration by other means is not possible.

POSTCODE LOOKUP
The de facto solution for address capture and validation in the UK.
Enter any UK postcode in the search field, click the search button and the drop down will show all the relevant address results for that postcode. Select the required address and the form will immediately be populated with accurate information.

ADDRESS AUTO-COMPLETE
Adds address auto-fill, lookup and validation to address forms for over 240 countries. Can be configured to allow the user to select which postal regions are required for delivery.
The checkout or form experience becomes faster and easier as a customer no longer has to type out their full address. The smart predictive search helps speed up form filling and boosts usability. Every address is verified at the point of entry. Problems due to incorrect or badly typed address data are drastically reduced.
Note: Address Auto-Complete currently only provides functionality for Shopify, Shopify Plus and Salesforce.
