Discover Phone Numbers

A telephone number or phone number is a sequence of numbers used to call from one telephone line to
another in a public switched telephone network. When telephone numbers were invented, they were short
— as few as one, two or three digits — and were given verbally to a switchboard operator. As phone systems
have grown and interconnected to encompass the world, telephone numbers have become longer. In addition
to telephones, they now access other devices, such as computers and fax machines. The number contains
the information necessary to identify uniquely the intended endpoint for the telephone call.

Spirion helps find and protect phone numbers. We first start with deep, deep data analysis.
When Spirion comes across data that could potentially be a match, it applies proprietary
validation techniques our data experts have developed after extensive data analysis to determine
whether the data is likely to be a Phone Number. These algorithms are updated every month with new information
to increase accuracy.

Beyond deep data analysis, Spirion also performs contextual analysis to increase
the accuracy of returning relevant information. By performing contextual analysis, Spirion can
ascertain whether the data is being referred to in a way that would also indicate it is relevant to
an end user.
