What percentage of phone numbers are VOIP?
On 2026-09-26, 0% of the 1,936 numbers checked on the 1Lookup platform matched: that is the VOIP share of checked numbers.
Measured across every completed lookup on the 1Lookup platform for 2026-09-26 (UTC). Aggregate only: no customer, organisation or lookup input is published. See the full briefing for that day.
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
