- ✓Valid or dead. Disconnected and unassigned 405 numbers are flagged before your dialer or SMS tool reaches them.
- ✓Mobile, landline or VoIP. Know which numbers can take a text and which are desk phones or app numbers.
- ✓Carrier. The carrier each number is on now, which can differ from the company that was first given the prefix because numbers are ported.
