Telephone Number Appending

CNM has been providing tele-appending services since 1994. We have access to an electronic directory of 26 million telephone numbers and XD flags. The directory is updated daily with up to 100,000 changes on any one day.

We understand that errors in your telephone numbers will result in wasted operator time, upset diallers, incur unnecessary cost, and potentially damage your brand. We also understand that match rates must be maximised and therefore employ additional referencing tools to enhance the availability of correct and accurate telephone numbers.

We understand that data is dynamic, and needs maintenance. We are constantly developing our services to meet these changes to ensure accurate address matching and STD Code and number verification to assess telephone number viability. We can also reduce your wastage by cross-checking your data against many industry files, such as Deceased, Gone-away and Movers information.

How does the service work?

You supply requests made up of names, addresses, and postcodes. CNM then uses computer searching to match your requests with telephone numbers.  The use of advanced computer systems and technology makes it fast, accurate, efficient and cost effective.

Telephone Number Appending forms part of our Data Cleansing Service, an example of what you can expect from this service is shown below:-

Example

You have the following data in your database:

Company Title Forename Surname Address1 Address2 Address3 Address4 Postcode
Before Data Cleansing for Telephone Numbers
CNM Limited 12 Appleton Court Calder Park Wakefield West Yorkshire WF2 7AR
Mr Joe Bloggs 12 Appleton Court Wakefield West Yorkshire WF2 7AR

This data is cleansed by the Telephone Number Appending service to:

Company Title Forename Surname Address1 Address2 Address3 Address4 Postcode Telephone
After Data Cleansing for Telephone Numbers
CNM Limited 12 Appleton Court Calder Park Wakefield West Yorkshire WF2 7AR 01924 888700
Mr Joe Bloggs 12 Appleton Court Wakefield West Yorkshire WF2 7AR 01924 888701

As you can see from the example it is easy for us to append telephone numbers to your existing data which also works out cheaper than buying a new set of data with telephone numbers.
