DOTS GeoPhone Plus 2
Instant Reverse Phone Lookup
For Over 400 Million US and
Canadian Phone Numbers
Our reverse phone lookup service accesses data from over 4,000 US,
Canadian and Puerto Rican telephone carriers, including 400 million phone
records and 170 million wireless numbers

Our real-time, reverse phone lookup API returns carrier and contact information based on the phone number provided. Caller contact information includes name, mailing address, address geocoordinates, phone type, line type and date ported. Wireless numbers also return associated SMS and MMS addresses. For business numbers, the SIC code is returned.

The reverse phone lookup also identifies high risk phone number types like portable VOIP and prepaid phones that are commonly used for fraud.
