What Does 'Msg & Data Rates May Apply' Mean?
If you have ever signed up for texts from a business, school, or nonprofit, you have seen the phrase: "Msg & data rates may apply." It appears in signup forms, keyword instructions, and confirmation texts so consistently that most people read past it. But the phrase is not filler. It is a required consumer disclosure with a specific history, a specific meaning, and specific places it must appear.
Quick answer: The phrase is required by industry policy, not by statute. The CTIA Short Code Monitoring Program Handbook requires a message and data rates disclosure in the call-to-action, the program terms and conditions, and the opt-in confirmation message, with an exception for free-to-end-user programs. Carriers enforce the same expectation on 10DLC programs through campaign vetting.

"Msg & data rates may apply" is a standard disclosure, required for short code programs by the CTIA Short Code Monitoring Program Handbook and expected by carriers and aggregators for other application-to-person programs, that tells a subscriber their mobile carrier may charge them under their own wireless plan for the text messages they send and receive as part of a messaging program. In other words: the organization texting you is not charging you, but your carrier might, depending on your plan.
This glossary entry unpacks the phrase word by word, explains where it came from, and shows exactly where it belongs in a compliant opt-in flow.
The Definition, Unpacked
- "Msg rates" refers to per-message charges. Wireless plans historically billed texts individually or against a monthly bucket of messages. If your plan charges for SMS, a message from a subscription program counts like any other.
- "Data rates" covers the mobile data used by messages that travel over the data network rather than the SMS channel, most relevantly MMS content and links you tap that open in a browser.
- "May apply" is the honest part. Whether you pay anything depends entirely on your plan. On today's typical unlimited-talk-and-text plans, the marginal cost of a program message is usually nothing. On prepaid, metered, or international plans, real charges can apply.
The disclosure exists so that no subscriber can be surprised by carrier charges triggered by a messaging program they joined. It allocates responsibility clearly: program messages are free from the sender, but your own carrier relationship is your own.
Where the Phrase Came From
The disclosure is a legacy of the premium SMS era. In the 2000s, "premium" shortcode programs charged subscribers directly on their phone bills for horoscopes, ringtones, votes, and trivia, often at premium per-message prices billed by the carrier. Abuse of that system (unauthorized charges known as cramming) produced regulatory attention from the FTC and state attorneys general, carrier reform, and ultimately the collapse of most premium SMS billing.
Out of that era, the wireless industry, through the CTIA, standardized consumer-protection requirements for all messaging programs. Standard-rate programs, the kind virtually every organization runs today, had to distinguish themselves from premium programs by telling subscribers plainly that the only charges involved are the subscriber's ordinary carrier rates. "Msg & data rates may apply" became the canonical formula, and the CTIA Messaging Principles and Best Practices, along with the CTIA Short Code Monitoring Handbook for shortcode programs, carried the requirement forward. Carriers and messaging aggregators audit programs against these documents, and 10DLC campaign vetting expects compliant opt-in flows, so the phrase functions as a de facto requirement for message deliverability even though no federal statute spells out those exact words.
Writing your opt-in language right now? The disclosure has to appear in the call-to-action, the program terms and conditions, and the opt-in confirmation message, and carriers do check. See how FRANSiS builds those in.
Where the Disclosure Must Appear
The CTIA framework calls for the disclosure at the moments a consumer makes or confirms a subscription decision. In practice, a compliant program includes it in these places:
| Location | Example |
|---|---|
| Call-to-action (web form, poster, keyword ad) | "Text JOIN to 555888 for updates. Msg & data rates may apply. Msg frequency varies. Reply STOP to cancel, HELP for help." |
| Opt-in confirmation message | "You're subscribed to Riverdale Food Bank alerts. Msg & data rates may apply. Reply STOP to opt out, HELP for help." |
| Terms and conditions / privacy policy | Full program terms restating message frequency, charges, opt-out, and support contact |
| HELP response | Program name or product description, plus customer care contact information. The Handbook does not require the rates disclosure here, though many programs include it |
The disclosure travels with its companions: program (brand) name, message frequency ("msg frequency varies" or a specific cadence), STOP instructions, and HELP instructions. Together these form the standard compliance block you see under nearly every SMS signup form. For complete, copy-ready examples of these flows, see our library of SMS opt-in message examples.
Getting the block right is not just etiquette. Carriers and aggregators review call-to-action screenshots during 10DLC campaign registration, and missing disclosures are one of the most common reasons campaigns are rejected or traffic is filtered. The broader rulebook, covering consent, content, and sender conduct, is worth understanding in full; our walkthrough of the CTIA messaging guidelines covers the whole document, not just this one phrase.
What It Means for Recipients Today
For most U.S. subscribers on unlimited plans, the honest answer is: nothing happens. Incoming program texts do not generate charges beyond what the plan already covers. The phrase still earns its place for the cases where charges are real:
- Prepaid and pay-per-use plans that meter texts individually
- International roaming, where inbound texts and especially data can carry significant carrier charges
- MMS-heavy programs, where picture and video messages may bill differently from SMS on some plans
- Data used by linked content, since tapping through to a donation page or video consumes plan data
Nothing about the disclosure changes the sender's obligations. The organization still needs proper consent under the TCPA (47 U.S.C. 227) and FCC rules (47 CFR 64.1200), still must honor STOP immediately, and still must identify itself. "Msg & data rates may apply" is one required brick in that larger wall.
Common Questions from Program Owners
Organizations setting up their first texting program tend to ask the same practical questions:
- Can we shorten or reword it? Stick with the standard formula. "Message and data rates may apply" spelled out is fine; creative paraphrases risk failing carrier review.
- Does it belong in every message? No. It belongs in the call-to-action, the program terms and conditions, and the opt-in confirmation. Routine ongoing messages do not need to repeat it.
- Does it apply to nonprofits, schools, and government programs? Yes. The CTIA framework applies to all application-to-person messaging regardless of sender type. Mission-driven senders follow the same disclosure rules as commercial brands.
- Do we owe the recipient's carrier anything? No. The sender pays its own platform and carrier fees for sending; the disclosure covers only the recipient's relationship with the recipient's carrier.
- What if we run a free-to-end-user (FTEU) program? Some shortcode programs arrange with carriers so recipients are never charged, in which case the Handbook exempts the program from displaying "message and data rates may apply" in advertisements, terms and conditions, and messages. Every other short code obligation still applies. These arrangements are the exception and must actually be in place before you advertise them.
How FRANSiS Handles It
FRANSiS builds the full CTIA-standard compliance block into opt-in flows by default: the rates disclosure, frequency language, STOP and HELP instructions, and program identification are part of every keyword and web-form enrollment, and the platform's automatic HELP and STOP responses carry the required content. The AI Powered Helper works inside the same rules, so two-way conversations are configured to preserve required disclosures. That supports a smoother 10DLC review, cleaner carrier audits, and subscribers who know what they signed up for.
Frequently Asked Questions
What does "Msg & data rates may apply" actually mean?
It means your mobile carrier may charge you for the texts you send and receive in a messaging program under the terms of your own wireless plan. The organization running the program is not charging you; the disclosure warns that your carrier might, depending on whether your plan meters messages or data.
Is "Msg & data rates may apply" required by law?
No federal statute mandates the exact phrase. The CTIA Short Code Monitoring Program Handbook requires a "message and data rates may apply" disclosure in the call-to-action, the program terms and conditions, and the opt-in confirmation message for short code programs, with an exception for free-to-end-user programs. The CTIA Messaging Principles and Best Practices does not use the phrase itself; it calls for clear and conspicuous language about opt-in and any associated fees or charges. For 10DLC, carriers and aggregators enforce the same expectation through campaign vetting and program audits. Practically, programs that omit it get rejected or filtered, so it functions as a mandatory requirement.
Do I get charged for texts from businesses or nonprofits?
On most modern unlimited plans, no; program texts are covered like any other text. Charges are possible on prepaid or metered plans, while roaming internationally, or through data used by MMS content and links you open. That variability is exactly why the disclosure says "may."
Where does the disclosure have to appear?
In the call-to-action where people sign up (web form, poster, or keyword instructions), in the opt-in confirmation message, and in the program's terms and conditions. The Handbook requires the HELP reply to carry the program name and customer care contact information, but not the rates disclosure. It does not need to be repeated in every routine message.
What is the difference between standard-rate and premium SMS programs?
Standard-rate programs cost recipients only whatever their own carrier plan charges, which is what "msg & data rates may apply" signals. Premium SMS programs, common in the 2000s, billed extra charges directly to the subscriber's phone bill and were largely shut down after widespread cramming abuse; modern messaging programs are standard-rate.
