Mobile carriers share a registry where legitimate businesses can tell them "this is our number, this is our business, please treat our calls as trustworthy." Registering here dramatically reduces the chance of your calls being labeled or blocked.
What we do for you
Submit the registration on your behalf as part of onboarding
Cover all three major U.S. mobile networks in a single submission
Re-register if any of your business details change
What you provide
Legal business name
Contact email for the carriers (in case they have follow-up questions)
A short, plain-language description of what your AI agents do on these numbers
Timeline
Submission: same day
Carrier review: 3 to 7 business days
You'll see improved answer rates within 1 to 2 weeks after approval
If you add new numbers later
They should be registered too. Any number you add to your account after the initial setup can be submitted for registration at any time from the dashboard.
A quick note: registration doesn't guarantee calls won't be labeled if your patterns look suspicious — it just reduces the chance significantly.
