What percentage of phone numbers are VOIP?
Today’s figure is not published: the platform did not see enough traffic for this measure to be reported without identifying an individual customer. The explanation below still holds.
What usually pushes this number up
- lead lists bought from aggregators, which carry a much higher VOIP share than numbers collected first-party
- form fills from users giving a throwaway number, which are almost always VOIP
- reactivated old lists, where landlines have been ported to VOIP carriers since collection
What brings it down
- a run of first-party lists, where people give a real mobile number they answer
- campaigns aimed at consumers rather than businesses, since business lines skew VOIP
- lists that were already scrubbed before upload
