Telephone Number Appending

We have access to BT’s OSIS database, the UK’s central repository for telephone numbers and are therefore able to append, where available, telephone numbers to your data. We understand that errors in your telephone numbers will result in wasted operator time, upset potential customers, incur unnecessary cost and potentially damage your brand name. Match rates must also be maximized and we therefore recommend that you have your file PAF validated beforehand to ensure the best possible match rates. We offer a comprehensive address validation solution that will update your addresses to the PAF standard format.
