Inteliquent Phone Number Lookup

What Is Inteliquent and Why Is It on My Caller ID?

Inteliquent is one of the largest wholesale voice carriers in the United States. It sells phone numbers and calling infrastructure to other companies rather than to consumers, and it is part of Sinch, the same carrier family as Onvoy. VoIP apps, conferencing services, business phone systems, and even other carriers run on its network.

Because Inteliquent is the carrier of record for the numbers it issues, its name is what caller ID and carrier lookup tools display. If a lookup shows "Inteliquent", "Sinch", or a Neutral Tandem label, the number was issued by Inteliquent's network; the actual caller is whoever uses the app or phone service built on top of it.

Is a call or text from an Inteliquent number spam?

Not automatically. Inteliquent carries enormous volumes of legitimate traffic: business phone lines, conference calls, appointment reminders, and two-factor codes. But like any network that supplies VoIP numbers in bulk, it is also used by spammers, because virtual numbers can be created online without a SIM card.

Never share a verification code with a caller, be wary of anyone creating urgency, and don't assume the name on caller ID is accurate. Use the lookup tool above to confirm a number's carrier and line type. To cut unwanted calls, block the number, turn on your carrier's spam filter, and report repeat offenders at donotcall.gov.

Frequently Asked Questions

Why does a phone number lookup show "Inteliquent" instead of a real person?

Carrier lookups return the company that issued the number, not the person using it. Inteliquent is a wholesale carrier that supplies numbers to VoIP apps, business phone systems, and other services, so the lookup shows Inteliquent even though the caller is a customer of one of those services. No public database links an Inteliquent number to an individual caller's name.

What is the relationship between Inteliquent, Onvoy, and Sinch?

They are the same carrier family. Onvoy and Inteliquent merged in 2017 under the Inteliquent name, and Sinch acquired the combined company in 2021. Depending on which number block a phone number comes from, lookups may show "Inteliquent", "Onvoy, LLC", "Neutral Tandem", or "Sinch", all pointing to the same network.

Is Inteliquent itself a scam company?

No. Inteliquent is a legitimate, licensed United States carrier that powers calling for thousands of businesses and apps. Scammers sometimes use VoIP numbers issued through its network because they are cheap to create in bulk, but Inteliquent carries the call; it is not the caller.

Can I find out exactly who called me from an Inteliquent number?

Not from a carrier lookup alone. A lookup tells you the carrier, the line type (often VoIP), and the number's registered location, which are useful signals for judging whether to trust a call, but not the caller's name. If a call claims to be your bank or a government agency, hang up and call back using the official number from their website.

What line type do Inteliquent numbers appear as in the API response?

Most appear as fixed or non-fixed VoIP under the line_type field, because Inteliquent primarily provisions internet-based calling services. Some business trunk lines can appear as landline. A VoIP line type is itself a useful risk signal when evaluating a phone number.

What number format is required when querying carrier data?

Submit numbers in international E.164 format with a leading + sign (for example, +15558675309 for a US number). This ensures consistent parsing across the 190+ countries the API supports.
