Configuration Options



Enable or disable extension altogether.


The API Key is required to verify your account for address validation. This can be found on your account dashboard on


Enable Postcode Lookup

This will present a Postcode Lookup search box on your address forms. The user will be directed to type their postcode and select an address from a list.

Enable Address Autocomplete

This will enable Address Autocomplete on the first address line on your address forms.

Enable Populate Organisation

Fill the Company field based on selected address. Enabling this will ensure that the organisation name in your form is populated by the organisation name present at the address selected by the user (if one exists).

Enable County

This will populate the region field with the county name. County data is no longer used in the UK to identify a premise. However, this can be enabled if you prefer.

Hoist Country Field

This will hoist the country input field to the top of your address form. This is useful if your default country is not a UK territory - lifting the country field to the top of the address form means that the user will be presented with the correct search tools when the get to address entry.

Our UK search solutions will only present on address forms where the selected country is a UK territory. When a non-UK territory is selected, our tools are detached from your form.


Your first key on your Ideal Postcodes account will carry a free test balance which you can use to verify and test your integration. Please contact support if you need a larger test balance.

Going Live

In order to go live, you will need to purchase a balance of lookups on your API Key. This can be done manually or automated from your dashboard. Each address search consumes one lookup from your key balance.

See our account setup guide for the quickest way to go live by creating your first API Key and enabling automated top-ups.


Your API Key is central to how our service recognises your integration. See our guide on API Keys to find out more.

API Keys can also be safeguarded against potential misuse, please see our guide on securing your API key to find out more.
