From shopping online to applying for jobs more and more companies are now asking customers or applicants to add a mobile number to online forms. But how do you know the number supplied is valid and true and active, and not just made up?
The short answer is that it depends on what you mean by ‘valid’ and there are 2 main ways that you one can answer that question.
To put it into context, at the very least a valid number must be the following:
- The right length
- Have the right prefix (for example in the UK mobile numbers typically start with ‘07’)
- Belong to an allocated range (because not all possible numbers are allocated to phone service providers)
You’d be amazed how many fraudsters just put in a fake number that ‘looks about right’ especially if they give an international number. Many businesses, who aren’t specialists in numbering intelligence, wouldn’t know a valid number from a fake one.
Secondly, how can you tell if the number is active? For this a different solution is needed.
Because network operators allocate numbers from within their ranges as they bring on new customers, it’s difficult to tell a valid number from a real (in service) one. You can’t really do this without doing some kind of real-time check at the network level, but if you do, you can be sure that the number you’re looking it is truly ‘valid and active’
