With our delivery validation feature, you can check if the customer is eligible for delivery. Depending on the address entered in the widget, a matching delivery location will be selected.
Maximum radius method checks the address that your customers entered in the widget. That address will need to be within the radius you entered in your location settings for the customer to be able to check out.

How does maximum radius work?
Enabling the maximum radius method will add a field to the Local delivery section of our widget.
You will need to enter your radius in the location settings.
Your customers will need to enter their address to check if delivery is available.
They will start typing their address and must select it from the dropdown menu.
If the address is within your delivery radius, they will be able to proceed.
The address will automatically populate in the next step of the checkout, if you have Prepopulate shipping address fields setting enabled in Settings > Local Delivery.
If the address is not within your delivery radius, they will get an error and not be able to proceed further.
Distance measured is the straight line distance from your store to the customer's address.
