Method List

Find who lives at an address

Obtain the names and telephone numbers of all residents who have lived, or are currently living, at a specified address.

This method will find who lives at an address in the UK, retrieving names and telephone numbers of both current and previous occupants.

This search is useful to any business or individual needing to identify the residential makeup of a property and find contact details to get in touch with owners/residents. Estate Agents, Building Societies, and Investigation companies are just some of the business sectors that would benefit from this service.

This ability to return the names of the occupants at a particular property is also useful to the marketing and sales teams of many businesses who only have an address and postcode. Instead of addressing their communication to ‘The Occupier’ they will be able to personalise it to a named person, thus improving their response rate.

API method to use: address_person

How it works

The method will return the names, and any telephone numbers, of people currently living at a specified address. Any past residents found will also be listed.

In order to return the above information, a unique UK address consisting of a full UK postcode and house name/number is required.

If the house name/number is not specified, a free list of addresses at which there is data about one or more people will be returned. Users can then select one address to see the names of residents.

Details on mandatory and optional parameters, with a list of returned values, can be found in the Documentation section.

Method Limits

The method has a limit of 100 persons to be returned, per address.

Should the address prove to have more than this total, only the first 100 persons will be returned. The <total_records> node will show 100, but the <uncapped_total> node will show the actual number of persons at the address.

Such addresses are very rare, and are mainly halls of residence, where the subdivision into discrete accommodation is not reflected in the single address point.

Result Caching

When a chargeable result is found (a list of residents) , the list is cached on our server for 60 minutes. If the successful search is repeated during that time, the list is displayed, but there is no charge.

Charging Policy

The method only charges when a valid postcode and premises are supplied.

There are two ways to authenticate your application with the T2A API. The two implementation examples on this page cover each type of authentication

We recommend using an API key for internal applications and the javascript key for public facing applications where you would want to protect your API key.

Please note: The examples below run on a sandbox environment which return sample data. To quality check the data we provide, up to 3 free searches are available in the demo tab with results showing live [REDACTED] data.

This example first needs to call to a file on your server, which will provide the user with an API key from your javascript key.

In our example above we have used a PHP file located at ajax/getExampleJSKey which looks like the example below

    <?php

        $url = 'https://api.t2a.io/rest/rest.aspx'
            . "?method=javascript_key"
            . "&api_key=sandbox" .
            . "&domain=" . $_SERVER['HTTP_HOST'];
            . '&ip_address=' . get_user_ip()
            . "&lifetime_minutes=10";

        $result = simplexml_load_file($url);

        if ($result->javascript_key) {
            echo (string)$result->javascript_key;
        }
