Twilio Voice Integrity Now Covers Verizon: Who Qualifies

October 19, 2026. Twilio's Voice Integrity, the beta that registers a business's outbound numbers with the analytics engines US carriers use to label calls as spam, now covers Verizon as well as AT&T and T-Mobile, according to Twilio's October 16 changelog. To qualify you need an approved Trust Hub Business Profile with an EIN or a DUNS number, a US business address, an authorized representative with a US phone number and a working https website. Twilio's US voice price list, read on October 19, has no Voice Integrity line; it lists Branded Calling at $0.12 a call.

What changed on October 16

1. Verizon added. Voice Integrity previously registered numbers with the analytics vendors for AT&T and T-Mobile. It now reaches the vendor that supports Verizon, so one registration covers all three major US networks.
2. No action for existing customers. Twilio says accounts already enrolled have had their business details and phone numbers registered with the Verizon-side vendor automatically.
3. Still a public beta. The Voice Integrity docs say it is not covered by Twilio's Support Terms or service level agreement, and that it is not a HIPAA eligible service or PCI compliant, so it should not be enabled in workflows subject to either.

Who qualifies, and how long it takes

Only phone numbers assigned to an approved Primary or Secondary Business Profile can be registered. Per the onboarding guide, Twilio's compliance team vets the profile in 24 to 48 hours, and registration with the analytics engines takes about another 24 to 48 business hours, so allow most of a working week before a new campaign. Enrollment runs through the Twilio Console or the Trust Hub API, with separate paths for direct customers, including outsourced call centers, and for software vendors or resellers whose customers place the calls. An agency that runs dialers for its clients fits the reseller description, since its customers are the ones calling.

What registration does not fix

Twilio is blunt about the limit: Voice Integrity "isn't a silver bullet" and will not make numbers immune to spam labels. Registration tells the analytics engines who you are; your calling pattern still decides the score. Our explainer on why a business number shows as Spam Likely names the three engines and the behavior they penalize, such as rotating numbers. Twilio recommends pairing registration with the highest SHAKEN/STIR attestation, CNAM and Branded Calling. The Free Caller Registry sends business details to the engines behind the same three carriers, First Orion, Hiya and Transaction Network Services, at no cost, and it too says registration does not guarantee calls will never be blocked or labeled.

What it means for operators

If you run an AI dialer for appointment reminders or speed-to-lead callbacks, register the numbers before the first campaign, not after the first complaint, and keep them steady. The costs are small: Twilio lists a US local number at $1.15 a month and outbound local calls at $0.0140 a minute, so 1,000 one-minute reminder calls cost $14 in Twilio minutes, and Branded Calling would add $120. Registration is not consent, either. Who you may call is still set by the TCPA and state rules, which our TCPA-compliant AI calling service builds in, and our state telemarketing laws guide maps calling hours by state.

Clinics should note the HIPAA exclusion before enabling it in patient reminder flows; our HIPAA-compliant AI receptionists list covers that side.
