Is the phone number lookup tool really free?

Yes, our free phone number lookup tool provides basic carrier information at no cost. You can perform up to 5 lookups per day per IP address without registration. For unlimited lookups, API access, and advanced features, you can sign up for our paid plans.

What information does the free lookup provide?

The free lookup provides voice provider (carrier) and messaging provider information for U.S. phone numbers. This includes the current carrier name for voice calls and the SMS/messaging carrier, which may differ for ported numbers.

Why are voice provider and messaging provider sometimes different?

When a phone number is ported (transferred) to a new carrier, the voice carrier changes but the messaging routing may still go through the original carrier's network. This is common with ported numbers and affects SMS delivery routing.

What phone numbers can I look up?

Our lookup tool supports all U.S. phone numbers including mobile, landline, and VoIP numbers. Enter any 10-digit U.S. phone number to get carrier information. Toll-free and international numbers are not currently supported.

How accurate is the carrier information?

Our carrier database is updated in real-time from authoritative sources including major carrier databases. Accuracy is typically 99%+ for active numbers. Results reflect the current carrier assignment at the time of lookup.
