Telephone Number Validation
A 2015 snapshot of UK telephone number validation showed that of the numbers being used by telemarketing companies, only 66% were active. With a massive one-third of telephone numbers inactive, telemarketing companies are wasting money and getting poorer results from their telephone operatives. 33% of numbers are inactive.

There are simple, quick and compliant ways to improve the quality of telephone numbers. Imagine how much you will save by not trying to call telephone numbers that are dead!
What would a 1 in 5 error rate do to your plans?
The 60 million UK population owns more than 83 million mobile phones and 33 million landlines. Even with high levels of portability of mobile numbers, the UK mobile market still has a churn rate of 3% per month. Overall, we estimate over 2,000,000 changes per month or a bit over 1 in 5 telephone number changes per year.
*Note: 2014 figures based on the Data Central Cache database. Our Cache data currently represents 44% of the total UK active telephone population.
A mobile marketer would have to be reckless, if they forecast results of a campaign based on an error strewn database. The smart thing to do is to get data checked out, then get it fixed. Similarly, a telemarketer calling landline and mobile numbers would want data to sail through diallers.
The best way to do this is to remove inactive and invalid numbers.
Does Telephone Data have the Worst Level of Accuracy?
Using our analysis, the answer is YES. Take name and address data. Most consumer data cleansing corrects for deceased and goneaway data. That is, those people who have died and those who have moved. Roughly 1% of the UK population dies each year and up to 15% of the population moves. This makes the level of telephone data decay the single biggest problem in terms of data quality by size, if not necessarily priority.
Deceased = 1%
Goneaways = 15%
Non-valid Telephones = 23%
