Wondering whether a number is VoIP, landline, or mobile? Here's how VoIP number lookups work, what a VoIP number is, and how to check a number's line type.
A VoIP number is a phone number that routes calls over the internet instead of a fixed copper or mobile line, so it can ring on any device.
Carrier/line-type lookups query numbering databases to return the line type (landline, mobile, VoIP) and the carrier of record.
Businesses check line type for fraud screening, SMS deliverability, and routing decisions before placing or accepting calls.
VoIP numbers behave like mobile in that they're device-independent, but appear as standard local numbers on caller ID.
CNAM lookups return the registered caller-ID name associated with a number, separate from the line type.
