How Phone Number Verification Really Works in the USA
The accuracy of a phone number database is one of the major factors that help in improving marketing, sales, and customer service. There are different ways of verification in the United States to check the accuracy of the phone number in the databases.

Some common verification methods:

Real-time Validation:

Carrier Verification: The verification of the phone number with the carrier to see if it is active and/or reachable.
Phone Number Intelligence: Advanced algorithms match phone numbers against a multi-million-member database of known data, including carrier, line type, and possible risk factors. Now, Batch Verification:

Bulk validation: It simply contains simultaneous processing in large batches, usually via API integrations.
Data Appending: Additional data, such as name, address, and email, are appended to the phone numbers in order to enhance the latter.
