Verifying Research with a non VOIP number

Research — like most services worth registering for — checks whether the number you enter belongs to a real mobile carrier. VOIP and internet-telephony numbers are commonly rejected at this step. Every number we issue is a genuine US carrier line, which is why they pass.

How it works
  1. Choose Research from the service list and place an order.
  2. A US number is issued to you immediately.
  3. Enter it on Research and request the verification code.
  4. The code appears on your dashboard as soon as it arrives — no refreshing.
What it costs

A Research verification costs $0.21, charged when the number is issued. That is cheaper than 3% of the services we carry. If no code arrives before the number expires, you are refunded automatically — you are never charged for a verification that did not happen.

Good to know

The number is rented for the duration of one verification, not sold. If you need a second code for the same account later, reuse is supported on many services. For automated signups, the same Research flow is available through our API.
