A privacy policy tells people what you do with their information. For texting, reviewers look for a promise that the phone numbers and consent you collect stay with you. CTIA's Messaging Principles ask senders to keep a clear, easy-to-understand privacy policy, show it with clearly labeled links, and make it reachable from the place where people opt in. Providers then add their own specific wording rules.

What must the SMS part of the policy include?

Item Why Who asks for it
No sharing or selling of mobile numbers for marketing Core consent protection Twilio (30908), Telnyx, Bandwidth, Vonage, Plivo
SMS opt-in data and consent excluded from any sharing Closes the "we share with partners" loophole Telnyx, Bandwidth, Vonage, Twilio (30932)
How you collect, use, and share information Basic privacy notice CTIA 5.2.1
Message frequency Tells people what to expect Twilio (collect business info, 30896)
Rates notice (message and data rates may apply) Fee disclosure Twilio (collect business info, 30896)
Public, no login needed Reviewers must be able to open it Twilio
Brand-specific and clearly labeled Shows it is your policy Telnyx

How is a strong SMS privacy section built?

A section that passes review usually covers these points, in plain language:

  1. Where people opt in. The page or method where you collect consent.
  2. How you use the number. Only to send the texts people signed up for and to answer them.
  3. The no-sharing promise. Mobile numbers and SMS consent are not sold or shared with third parties or affiliates for marketing.
  4. The carve-out. If the policy allows other data sharing anywhere else, it must say SMS opt-in data is excluded.
  5. Frequency and rates. How often you text and that message and data rates may apply.
  6. STOP and HELP. How to opt out and get help, with a link to your SMS terms.
  7. Contact details. Your business name and a way to reach you.

The carve-out is the part most people miss. A policy can promise no SMS sharing in one paragraph and still fail if another paragraph says you share data with partners.

Why does Twilio want only one privacy policy?

Twilio error 30908 lists "multiple conflicting policies" as a rejection reason. If your site has an old policy in the footer and a new one on another page, a reviewer may find the wrong one. Keep one policy at one URL, link to it everywhere, and paste that same URL into your campaign form.

What are common privacy policy mistakes?

  1. Sharing language. Phrases like "we may share your information with partners for marketing" conflict with the no-sharing rule. Twilio 30908 and 30932 both flag this.
  2. No SMS clause at all. A general website policy that never mentions texts or mobile numbers.
  3. A generic or reseller policy. Telnyx says the policy must be brand-specific, not a template or a reseller's policy.
  4. More than one policy. Conflicting versions on the same site (Twilio 30908).
  5. Hard to reach. Behind a login, in a download, or broken. Twilio says it must be public with no login.
  6. Hidden link. CTIA asks for a clearly labeled link, and Telnyx says links should not be pop-ups.

Put it in three places:

  1. Your site footer, labeled "Privacy Policy".
  2. Next to the SMS consent checkbox on your opt-in form.
  3. The Privacy Policy URL field of your campaign registration.

Bandwidth says the link goes in Campaign Details. Twilio added a dedicated Privacy Policy URL field to its Console on February 18, 2026.

Which providers say this?

Provider What they say
Twilio One clear policy stating mobile numbers and messaging consent are not shared with or sold to third parties or affiliates for marketing (30908); no sharing opt-in data with lead generators (30932)
Telnyx Brand-specific, clearly labeled; not sold or shared for promotional or marketing purposes; exclude SMS opt-in data if other data is shared
Bandwidth Mobile info not shared with third parties or affiliates for marketing; opt-in consent data not shared
Vonage No mobile info shared for marketing; originator opt-in data and consent excluded from any sharing
Plivo Includes a no-sharing clause

How does 10DLC Site handle it?

Every site we build includes one privacy policy at a single URL, written for your brand name, with an SMS section that covers the no-sharing clause, frequency, rates, STOP, and HELP. It is linked in the footer and next to the opt-in checkbox. Compliance Watch checks daily that the policy page is live and the SMS clause is still there.
