The phone number line status is the last section of a telephone number that identifies which device it belongs to. While area code and prefix pinpoint the location, the line number is unique to the individual phone it belongs to. Having separate lines for personal and professional calls gives busy executives an easy way to screen incoming messages without disrupting business calls.
Phone Number Line Status: Verifying Phone Numbers for Accuracy
For example, a manager could configure a line for personal calls so friends and family can reach her while another would be used for work-related messages. This allows the manager to quickly distinguish between different types of messages by glancing at the caller ID on her smartphone. The manager can then decide if she wants to take the call or pass it on to someone else.
How to check Phone number Line status
While most services validate phone numbers by checking syntax, number length, area code and dialing code, HLR lookups go further to query the mobile network to get real-time carrier data such as MSIDN, subscriber name, and line status. This enables faster validation and ensures that leads or user data are active and accurate.
If a phone number has a Flagged or Restricted status, this means the line is no longer eligible to receive notification messages. Once the line is back to a Connected status, the messaging limit will be reset within 3 days. A Flagged status indicates that the phone number is experiencing low messaging quality and will remain in this state until it improves to a high message quality rating.
