What do people think of Reachable Phone Number Self-Service Batch Tool?
This service offers near 100% accuracy for identifying the line type and the current carrier of a phone number. The service includes and LNP check (Local Number Portability) to verify if the number was moved (ported) to a new phone company.
This service will also report new carrier and the new line type, even if the number was ported today!
Mobile phone numbers also include the SMS/MMS email address (lets me email text or media messages instead of paying for text service) plus it checks if the numbers in your list are Reachable.
Phone are considered unreachable, if they are invalid, disconnected, blocked or appear inactive. They even report if phone number is on the Federal Do Not Call (DNC) list. Data is updated daily and I can run files 24/7.
