Can I enable it on more than one Address field in a form?

Yes. The setting is per field, so billing and delivery addresses can each have lookup. Keep one lookup-enabled field per page.

Does it work with multi-page forms and conditional logic?

Yes. Lookup runs in the browser on the page the Address field is on. Conditional logic keeps working as before.

What if a visitor's address is not in the list?

The inputs stay editable. They can type the address by hand, as they can today.

How many lookups does a form submission use?

One per postcode search. Picking an address from the list is free.

Why add postcode lookup to Gravity Forms

Fewer abandoned forms

The Address field asks for five things. Lookup turns that into one postcode and a click.

Addresses you can act on

Every entry carries a complete, correctly spelt address. Quotes, deliveries and callbacks go to the right place first time.

Nothing else changes

Entries, notifications, feeds and conditional logic keep working. The plugin only fills the Address field's own inputs.

Set up in four steps

Install and activate the plugin

Download the zip from your dashboard and upload it under Plugins › Add New Plugin.
Paste your API key

Forms › Settings › UK Postcode Lookup. One key covers every site you run.
Tick the box on the Address field

Edit the form, select the Address field, and tick "Enable UK Postcode Lookup" on the General tab.
Test it

Preview the form, search a postcode, pick an address and check the entry.

What fills where

The plugin writes into the Address field's standard inputs, so entries, exports and add-ons see the data exactly where they expect it.

Address line 1	Street Address	Flat 4
Address line 2	Address Line 2	22 Castle Street
Town	City	Norwich
County	State / Province / Region	Norfolk
