You can check which carrier a number is on today, for free.

Enter the full number to see its carrier now, which may not be Onvoy if the number was ported. It is the same free check as our carrier lookup. To see whether it is a mobile, landline or VoIP line, use the line type lookup, and to see who it is listed to, the who called me lookup.

A lookup shows Onvoy when the number comes from a service that gets its numbers there.

Onvoy rarely sells phone service to the person using the number. Internet calling apps, VoIP phone systems, call centers and business phone services get their numbers from carriers like Onvoy, so a lookup shows the carrier behind the service, not the service itself.

So when a lookup says Onvoy, the number most likely belongs to someone using one of those apps or services, and the lookup does not name the app.

Numbers can also move between carriers, so a lookup reads the number's carrier today, and a number with an Onvoy prefix can show another company if it was ported.
