Is an Onvoy phone number VOIP?
ApplySift reads it as: VOIP wholesalerYes. Onvoy is a carrier whose numbers are provisioned by software to VOIP platforms and apps, not sold as phone lines to people. When a reverse lookup on an applicant's number says ONVOY SPECTRUM, LLC, this is what it means.
What Onvoy is
Onvoy, LLC and Onvoy Spectrum, LLC are the names under which Inteliquent holds numbers. Inteliquent is a Chicago wholesale carrier; it merged with Onvoy in 2017 and was bought by Sinch, the Swedish messaging company, in 2021. Neutral Tandem was Inteliquent's earlier name and still appears on its Puerto Rico blocks. None of these companies sells phone service to the public. Their customers are VOIP platforms, contact-centre software, messaging apps and other carriers, who order numbers from them by API and hand them out to their own users.
By the numbers
Every North American number belongs to a block of a thousand, and every assigned block is listed with its holder in NANPA's public thousands-block report. Some holders are also assigned whole exchanges of ten thousand numbers in the central-office code report. These counts are from the October 2026 reports. The area codes with the most Onvoy blocks are 346, 470, 240, 667, 970, 217, which says more about where numbers are in demand than about where the applicant lives: a number from a wholesaler is picked from whatever area code the buyer asked for.
How it appears in a lookup
The record lists the legal entity that holds the block, often with a state suffix. Onvoy appears under these names, most common first:
- ONVOY SPECTRUM, LLC (31,633)
- ONVOY, LLC - CA (21,384)
- ONVOY, LLC - TX (15,131)
- ONVOY, LLC - FL (11,562)
- ONVOY, LLC- NY (10,252)
- ONVOY, LLC - PA (8,483)
- ONVOY, LLC (8,479)
- ONVOY, LLC - OH (7,287)
Why an applicant's number lands here
A number in an Onvoy block was provisioned through some platform built on Inteliquent's network: a softphone app, a virtual-number service, a dialer, a texting tool. That is how an applicant ends up with one without ever having heard the name. Together Onvoy's entities hold more thousands-blocks than any other group in the record, so this is the single most common holder of a VOIP applicant number.
In one real pool of 1,455 applications to a remote engineering role, 60% of the phone numbers were in wholesaler blocks like these; a paid line-type lookup agreed with the public-record check on 99% of them. Why fraud rings use VOIP numbers explains the pattern, and the signals page gives the weight this reason carries in a score.
What this does not tell you
- Ported numbers. A number moved from one carrier to another keeps its original block in the public record. A real mobile number ported to a VOIP app still reads as the mobile carrier, and an Onvoy number ported to a mobile carrier still reads as Onvoy. Porting data is not public, so no free lookup can see it.
- Who the person is. The record names the carrier, never the subscriber. ApplySift uses the block holder as one signal among several and never rejects anyone on its own.
