SMS Compliance in 2025: A Practical Guide for Marketers and Business Owners

Staying on the right side of the rules means your messages get delivered, your brand stays trusted, and you avoid painful fines. Below is a no‑nonsense roadmap you can follow today.
Why SMS Compliance Matters More Than Ever
- Strict new FCC rules. In December 2023 the FCC codified tougher robotext regulations and required wireless carriers to block messages that appear unlawful, closing what it called the “lead‑generator loophole.” Those provisions took effect March 26 2024.

- 10DLC enforcement deadlines. U.S. carriers now treat virtually every business text as A2P traffic. Any 10‑digit long‑code (10DLC) campaigns that are not registered through The Campaign Registry (TCR) will be blocked outright beginning February 3 2025. Telnyx Help Center
- Global data‑privacy pressure. State‑level statutes such as the CCPA (California) join federal TCPA rules, CAN‑SPAM for commercial SMS, Canada’s CASL, and the EU’s GDPR. Penalties range from carrier surcharges to multimillion‑dollar class‑action settlements.
The Core U.S. Regulations at a Glance
| Regulation | Applies to | Key Requirement | Penalties |
| TCPA (Telephone Consumer Protection Act) | Marketing & some transactional texts | Prior express written consent; opt‑out (“STOP”) | Up to $1,500 per message |
| FCC Robotext Order (2023‑24) | All SMS/MMS | Carriers must block texts that violate TCPA; clarified “one‑to‑one” consent standards | Service suspension & fines |
| CTIA Messaging Principles | Short codes, toll‑free, 10DLC | Content guidelines, opt‑in/opt‑out, quiet hours | Carrier blocking & fees |

| CAN‑SPAM | Commercial email and SMS | Sender ID, opt‑out link or keyword, no deceptive subject | Up to $51,744 per violation |
Six Pillars of a Compliant SMS Program
- Clear, Documented Consent
- Use unchecked opt‑in boxes; disclose message frequency and that “Msg & data rates may apply.”
- Store timestamp, phone number, and disclosure wording in your CRM.
- Lead‑generation websites must collect brand‑specific consent—bulk “partner lists” no longer count. Federal Register
- Proper Sender Identification
- Every message should state who is texting within the first few characters.
- For multi‑location brands, include a store or service line name for transparency.
- Opt‑Out Mechanism That Works 24/7
- Accept STOP, CANCEL, END, QUIT, UNSUBSCRIBE.
- Honor requests within 24 hours; carriers expect real‑time suppression.
- Content & Timing Controls
- No SHAFT content (sex, hate, alcohol, firearms, tobacco/vape) unless you meet strict age‑gate rules.
- Respect consumer time zones—quiet hours (8 p.m.–8 a.m. local) are recommended by CTIA.
- 10DLC Campaign Registration
- Audit & Monitoring
- Review your opt‑in language quarterly.
- Track carrier filtration rates; sudden drops can signal compliance flags.
- Keep a living compliance playbook accessible to marketing, sales, and dev teams.
Consequences of Non‑Compliance
| Violation | Possible Outcome |
| Sending without consent | Class‑action lawsuits under TCPA (statutory damages up to $1,500/msg) |
| Unregistered 10DLC traffic (after Feb 3 2025) | 100 % blocking by U.S. carriers; brand suspension |
| Misleading content (CAN‑SPAM) | FTC civil fines; personal liability for executives |
| Ignoring opt‑out requests | Carrier surcharges; loss of short code or TFN |
Building a Future‑Proof SMS Strategy
- Centralize consent capture across web forms, POS systems, and CRMs.
- Automate suppression with real‑time APIs and nightly reconciliation.
- Segment messaging types—marketing, two‑factor authentication, support—then register each 10DLC campaign with the appropriate classification.
- Use compliant templates so every team (marketing, CX, product) pulls pre‑approved copy.
- Stay informed. Bookmark the FCC’s “Targeting and Eliminating Unlawful Text Messages” docket and carrier update pages.
What to Expect Next
- Verified Sender ID across channels. Carriers and the GSMA are piloting verified SMS profiles (think “blue check” for texts) to further cut spoofing.
- AI content scanning. Machine‑learning filters are already flagging link shorteners and shady keywords—expect stricter real‑time filtering.
- Stronger state laws. States such as Florida and Oklahoma have introduced “mini‑TCPA” statutes with lower consent thresholds and higher per‑violation damages.
Final Thoughts
SMS Compliance isn’t a box to tick—it’s a revenue safeguard. By pairing thoughtful consent flows with diligent 10DLC registration and ongoing monitoring, you keep your deliverability high and your legal exposure low.
