What Address Capture Does

Address Capture provides real-time address autocomplete and verification as users type. The service provides:
  • Type-ahead address search: Returns matching addresses as users type, reducing manual data entry and improving form completion speed
  • Global address coverage: Access to address data for over 250 countries and territories worldwide
  • Multiple response formats: Returns addresses in Label, Lines, or Elements format to match any form structure
  • Geolocation support: UK users can find their location with a single tap using device coordinates (AddressBase Premium)
  • Container drill-down: Navigate through address hierarchies (postcodes, streets, buildings) for precise address selection
  • Customizable integration: Available via Tag snippets, SDK, direct APIs, or pre-built platform integrations
  • Search highlighting: Visual indicators show which characters match the user’s search term
  • Custom field mapping: Return additional data like coordinates using Field1-Field20 parameters

Capture APIs

See all of the Address Capture API docs.
There are several methods for integrating Address Capture:
  • Tag: insert automatically-generated code snippets into your website to add Address Capture to your online forms
  • Pre-built integrations: enable Address Capture in a range of pre-built integrations with tools like Adobe Commerce, Microsoft Dynamics 365 and Shopify plus
  • SDK: use our Address Capture SDK to quickly create a custom integration
  • APIs: use our Address Capture APIs for full customisation of your integration
If you’re not sure which integration method is most appropriate for your business needs, see our Ways to Integrate page for more details.

Address Capture

​
Mapping Response Fields to Forms

Address Capture provides each address in three different formats:
  • Address label: great for displaying the complete formatted address in a single field or on an envelope
  • Address lines (recommended): use these where you have multiple address line fields. Used alongside Company, town and postal code fields most commonly
  • Address elements: each individual element of the address (e.g. building, street) where you need to separate the lines of an address into individual fields
Any one of the above approaches will lead to a complete address. The full set of fields can be found in the API documentation pages.
It is best not to mix fields from the different formats, as this can lead to missing or duplicated information.

​
Client-Side vs Server-Side Integration

When deciding how to integrate the Address Capture APIs, your decision should take into account performance, technical complexity and, most importantly, security. Whether or not to make calls client-side or server-side is part of the decision-making process regarding security. The API Security page has a section relating to integration options, which should help you decide which option is best for you.

​
Getting Latitude and Longitude Coordinates

Various additional fields are available when you get an address from the Retrieve endpoint, and (where the data is available) this includes latitude and longitude. When using the API, this is achieved by the fieldxformat parameters within the Retrieve method. In order to request the latitude and longitude you need to add them into the parameters, like below: 
&field1format={Latitude}&field2format={Longitude}
This will then return Latitude and Longitude in Field1 and Field2 in the response respectively. If consuming the service via the Tag method, you can enter the same input into the mappings wizard.

Geolocation

​
About Geolocation

Loqate’s Geolocation feature enables mobile users in the UK to find their location with a single tap, instead of needing to type in an address. Using the geographical location of the mobile device, Geolocation returns latitude and longitude coordinates alongside the full, correctly-formatted address.

​
Integrating Geolocation

There are several ways of integrating Geolocation on your website. Documentation is available for each integration option, so please see the links below for the relevant information. If you’re not sure which option is best for your organisation, you can find out more on the Ways to Integrate page.

​
Geolocation Search Radius

The radius is set to 50m by default, but can be adjusted to anything from 1 to 200 metres. If using a Tag integration, contact the Loqate support team to adjust the radius. In other integrations you can set the radius when making a call to the service.

​
Number of Addresses Returned

The maximum number of addresses returned is set to 10 by default (using the API - in a Tag integration it’s set to 5), but can be adjusted to anything from 1 to 50. If using a Tag integration, contact the Loqate support team to adjust the maximum number of addresses. In other integrations you can set this when making a call to the service.

​
Geolocation Coverage

Geolocation is available in the UK only, using AddressBase Premium data.

​
Geolocation Pricing

Geolocation can be paid for either on a pay as you go basis or via a license agreement. Get in touch with the Loqate support team to find out more.
