Jotform Integration

This guide outlines how to attach Address Finder on your form.


  • Bind Address Finder to your address fields
  • Add one or more Postcode Lookup fields

If you need support, you can either reach out to us on our support page or drop by our developer chat page.


Address Finder

Quickly populate your address fields-screenshot


Create Address Inputs

Add address input fields to your form. These should be created using Short Text fields found under Basic Elements. A basic address form to capture a correct UK address requires the following fields:

  • Address line one
  • Address line two
  • Address line three
  • Post town
  • Postcode

You may add other address fields, which are listed on the address documentation page.

Note the Field ID number for each address field in the Short Text Properties side panel. You will need this later to configure the Postcode Lookup Plugin and/or Address Finder Plugin.

Add Address Finder

Insert Source Code

On your page, add an HTML block and paste the form's source code.

On the online form builder, go to Publish -> Embed -> Source Code

Jotform add HTML Block

Jotform add Source Code Block

Insert Initialisation Code

Place another HTML block under the first one and paste the code below:

<script src=""></script>

document.addEventListener("DOMContentLoaded", function () {{
apiKey: "ak_test",
outputFields: {
line_1: "#input_3",
line_2: "#input_4",
line_3: "#input_5",
post_town: "#input_6",
postcode: "#input_7"

Take special care to:

  1. Insert your API Key in the apiKey field
  2. Update the input field names of your target fields. If your Address Line One Field ID is #input_1, this line should be replaced with 'i#input_1'. Do this for all the address fields you wish to include

If you wish to add an additional field, include the parameter name from our documentation. For instance, adding a county field with Field ID #input_8 will look like:

outputFields: {
line_1: "#input_3",
line_2: "#input_4",
line_3: "#input_5",
post_town: "#input_6",
county: "#input_8",
postcode: "#input_7"
