The Matchcode integration enables street level postcode lookups. You will need an active 'Matchcode UK Address - Address' license (https://www.gbgplc.com/uk/products/gbg-matchcode360) to use the integration. After signing up with their service go to the Menu option, Tools > Postcode Lookup > Matchcode Setup.

On this page you will need to enter your Matchcode account details. This is the same details that you will use to login to the Matchcode login.

Once you have configured the Matchcode details you will see a 'Get Address' button appear next to the Postcode field within an account.

This button can then be used to retrieve address details from Matchcode. The lookup will automatically set the address on the Account. The Address1-4 fields will be set to the necessary address information.

You will need to save the Account as normal to save the Address changes.
