SMS Opt-In Generator: CTIA-Style Consent Language Templates
Generate a web-form disclosure, welcome text, and privacy policy clause for SMS opt-in. Follows current CTIA and 10DLC consent conventions, ready to copy and paste.
Web-form checkbox disclosure
By checking this box, you agree to receive promotional and marketing text messages from [Your Business Name] at the phone number provided. Message frequency varies, up to 4 messages per month. Message and data rates may apply. Reply STOP to opt out at any time, or HELP for help ([your support email or phone]). See our privacy policy for details.
Welcome / confirmation text
[Your Business Name]: You're in! You'll get up to 4 promotional and marketing texts per month. Msg & data rates may apply. Reply STOP to unsubscribe, HELP for help ([your support email or phone]).
Privacy policy SMS clause
SMS Communications. If you opt in to receive text messages from [Your Business Name], we use your phone number solely to send promotional and marketing messages related to our business, at a frequency of up to 4 messages per month. We do not sell or share your mobile phone number or opt-in data with third parties for their own marketing purposes. Message and data rates may apply. You may opt out at any time by replying STOP, or get help by replying HELP or contacting us at [your support email or phone].
These are templates based on common CTIA and 10DLC conventions, not legal advice. Have your final opt-in flow reviewed before launch.
What this tool does
Fill in your business name, an optional program name, the types of messages you send, your monthly message frequency, and a help contact, and this tool generates three ready-to-use blocks of consent language: the checkbox disclosure that belongs next to your web form opt-in, the automated welcome or confirmation text a new subscriber receives immediately after opting in, and a short paragraph to drop into your privacy policy describing your SMS program. Each block follows the wording conventions carriers and The Campaign Registry expect: message type, frequency disclosure, the message and data rates may apply line, and clear STOP and HELP instructions.
Who it's for
Small business owners and marketers setting up their first SMS opt-in form, and agencies standing up A2P 10DLC programs for multiple clients who need consistent, compliant language without rewriting it from scratch every time. It is built for anyone who has looked at a competitor's opt-in checkbox and wondered what exact wording they are supposed to use.
How to use it
- Enter your business name and, if you use one, a specific program name like VIP Text Club.
- Check which message types you send: promotional, transactional or order updates, and appointment reminders.
- Set your typical messages-per-month frequency.
- Enter a help contact, an email or phone number, for the HELP response.
- Copy the web-form disclosure, welcome message, and privacy policy clause using the copy buttons under each block.
- Paste each block into the matching spot: disclosure next to your checkbox, welcome message into your automation platform, and clause into your privacy policy page.
Good to know
These are template language blocks based on common CTIA guidelines and current 10DLC carrier expectations, not legal advice. Consent requirements can vary by message type, state, and your specific carrier or aggregator's review standards, so have a qualified professional review your final opt-in flow, especially for regulated industries like debt collection, healthcare, or financial services.
Frequently asked questions
What has to be included in an SMS opt-in checkbox disclosure?
At minimum it should name your business, describe the type of messages being sent, disclose that message frequency varies or state a maximum per month, include the phrase message and data rates may apply, and give clear STOP and HELP instructions. This generator builds all of that into one paragraph based on the message types and frequency you select.
Does the opt-in checkbox need to be unchecked by default?
Yes, for express written consent under TCPA and standard carrier expectations, the checkbox must start unchecked so the subscriber actively opts in themselves. A pre-checked box, or consent bundled into a general terms of service checkbox, is a common reason campaigns get rejected or flagged during carrier review.
What should the automated welcome text say after someone opts in?
It should confirm the business name, restate the type and expected frequency of messages, and repeat the STOP and HELP instructions, since this is often the first actual text message a subscriber receives and doubles as your program's confirmation record. This tool generates that welcome text automatically from the same details used for your disclosure.
Do transactional messages like appointment reminders need the same opt-in language as marketing texts?
Transactional and appointment messages still need express consent and STOP and HELP handling, but the frequency and content framing can differ since they are tied to an account or service relationship rather than promotions. This tool lets you select transactional or appointment reminder types separately so the generated language matches what you are actually sending.
Can I use the same opt-in language for multiple clients if I run an agency?
You can reuse the structure, but the business name, program name, message types, and frequency need to reflect each specific client's actual program, since carriers compare your registered campaign details against the consent language shown to subscribers. Regenerate a fresh set of blocks per client rather than swapping only the business name.
What goes in the privacy policy SMS clause and where should it live?
It should state that phone numbers collected for SMS are not shared with third parties for marketing purposes, describe the message types and frequency, and repeat the opt-out method, and it typically lives as its own subsection inside your existing privacy policy page. This is a common area carriers check during campaign vetting, so a missing or vague SMS clause can slow down registration approval.
