Find a business telephone number

Search current UK telephone data to find UK business telephone numbers by name and/or location.


Users of your website, CRM system or other application can find contact details on the company they have searched for. This can be especially useful for sales and marketing teams operating in Business to Business markets who wish to make contact with prospective customers.

With our data updated daily, you won’t find a more up-to-date source of UK company information available. Plus, with our ‘fuzzy matching’, the method will still return a result of the closest possible matches even if the company name is inaccurate or has been entered incorrectly.

API method to use: business_search

An additional amount of company information can also be obtained by combining this method with company_details.

How it works

The method searches the UK Phone Book and Companies House data to return a company or business and it’s listed telephone number, address and website. A result is achieved when the following data is supplied:

  • Company Name
  • City, town or postcode (optional location to narrow results)
  • Business type (optional, can be combined with location if company name not known to find particular types of businesses in a certain area).

If an exact match to a company name cannot be found, our ‘Fuzzy-matching’ will return a set of closest matches to the details entered.

All the mandatory and optional parameters, together with returned values, can be found in the Documentation section.

Next Steps…

We will give you a unique API key to allow you to test the method using credits on your T2A account. The Demo tab will allow you to test the parameters required and view the result.

If you do not have an account you will first need to sign up

Search the phone book and companies house for a business.

Updated daily, you won't find a more up to date source of company/business information.

We employ a method of 'fuzzy-matching' when performing searches, meaning that even if a name or address is inaccurate or entered incorrectly, we will search the closest possible matches. If there is information on a company/business available, we'll find it.

Most limited and non-limited companies return a company number/ID which can be used with the company_details method to obtain full information on that organisation.

Mandatory Parameters


Name Description
api_key or javascript_key Use your API key if invoking server-side. If invoking from the browser via JavaScript, generate a JavaScript key using the javascript_key method.

Optional Parameters


Name Description
client You can optionally include an identifier for your final client or user. This is logged in your usage log and you will be able to view your usage statistics by client.
output Set to json for a JSON response; the default response is XML. Not applicable to the SOAP API.
callback When using JSON, specify a JSONP wrapper in which the JSON response is to be wrapped.
name The business name.
use_non_company Set to false to NOT search phone book data. Defaults to true.
use_company Set to false to NOT search company data. Defaults to true.
company_number Specify a company number to check if it is valid.
records_per_page Specify the number of records to return on the current page. We offer page caching for this method - once your search is invoked, we store the pages on our server for 60 minutes; a subsequent request for a page of results from that search is displayed from the cache, at no charge to you. See result page caching.
page_num Zero based integer - current page number to return.
place Enter a UK place, postcode, or postcode area. Do not specify this to do a national UK search.
street The street name.
premises The building number or name.

Returned Values


The XML response is contained within a <business_search_res> element.

Name Description
status Returns ok if the operation has succeeded, or error if an error has occurred; Returns the error_code for error details.
error_code Returns the error code when the status is error. See below for error codes.
t2a_version_number The current API version number.
credit_used The number of credits used in order to execute the request.
mode Returns normal or test when executed in the free test mode.
business_list

An array of business records.

place_list An array of place records. This is present if the place name is ambiguous. No charge is made when a place_list is retuned.
total_records

The total number of records, irrespective of the number displayed on any page.

This is only used when a business_list is present.

page_number

Current page being displayed, a zero-based integer.

This is only used when a business_list is present.

Error Codes


See the common error codes. There are no errors which are specific to this method.

Free Test Mode


When operating in the free test mode errors are returned if mandatory parameters are missing, or it returns a dummy data response, in an identical format to a real response.

Note that the mode is returned as test when the method is operating in the free test mode.

The free test mode for this method operates in the following manner:-

  • If the place parameter is set to leeds, a place_list is returned.
  • If not, a dummy business_list is returned.

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.

Note: examples below show a restricted result set with a maximum of 3 results per search

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=O6H0ZB_x0tdqHZPXPNGcthhiD1K2Iqinq5GYV5q3f6_H" .
            . "&domain=" . $_SERVER['HTTP_HOST'];
            . '&ip_address=' . $_SERVER['REMOTE_ADDR']
            . "&lifetime_minutes=10";

        $result = simplexml_load_file($url);

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