Line Type indicates whether a phone number is wireless (mobile), landline, VoIP, or toll-free. Line type affects SMS capability, fraud risk assessment, and optimal communication channels for reaching contacts.
Line Types
- Wireless — Mobile phones, SMS capable
- Landline — Traditional wired phones, limited SMS
- VoIP — Internet-based phones, variable SMS
- Toll-free — 800/888/etc. numbers
