Who This Is For / Who It Is Not For
Who this is for: US businesses, compliance owners, marketing ops, and product teams that send or enable A2P SMS and need practical registration, consent, or troubleshooting guidance tied to 10DLC/TCR and TCPA concepts.
Who this is not for: Readers seeking invented fine amounts, guaranteed approval rates, or universal throughput figures; purely P2P consumer texting with no application layer; teams outside US A2P rules who need only foreign-regulator advice.
Short answer: The FCC’s primary text-relevant rules live in the TCPA framework, especially 47 CFR § 64.1200 (delivery restrictions for telemarketing and related calls/texts). Businesses must manage consent, content type, and revocation. Separately, US carriers require A2P 10DLC registration for local long-code application messaging. “FCC text message guidelines” are not a single brochure—and CTIA best practices are not FCC regulations.
Worked example: applying FCC rules to a texting program
A healthcare scheduling service maps its texts to FCC rules. Appointment reminders may qualify for the healthcare treatment exemption if conditions are met; marketing for elective services requires express written consent; opt-out requests made by any reasonable means, including replies like "stop texting me", must be honored within the FCC's required timeframe.
It also checks the Reassigned Numbers Database before contacting patients who have not been seen in over a year, because a reassigned number's new owner never consented and the FCC's safe harbor depends on that check.
The Regulatory Map
| Layer | What it governs | Example source |
|---|---|---|
| FCC / TCPA | Consent, telemarketing restrictions, certain calling hours for telephone solicitations, revocation | 47 CFR § 64.1200 |
| Carriers / TCR / CSP | Brand/Campaign registration, filtering, throughput | Twilio A2P 10DLC, TCR resources |
| CTIA best practices | Industry expectations for opt-in/opt-out, program transparency | CTIA Messaging Principles |
| State laws | May add stricter telemarketing/text rules | Vary by state—ask counsel |
Confusing these layers causes false confidence (“we’re registered, so FCC is done”) or false panic (“CTIA PDF is a statute”).
Core Themes in § 64.1200 for SMS Programs
Consent
- Marketing/telemarketing texts using covered technologies generally need prior express written consent.
- Some informational traffic may rest on prior express consent without the full written marketing formalities—content-specific.
- Limited rule text addresses certain nonprofit and health-care message contexts; these are narrow—not blanket exemptions.
Clear authorization elements for PEWC
Written agreement, signature, identified number, clear disclosures including that consent is not a condition of purchase—see the regulation’s definition and our PEWC article in this draft set.
Revocation
Consumers may revoke consent by reasonable methods; STOP-style replies are called out as reasonable means per se in the current rule text. Build suppression that actually stops covered traffic.
Telephone solicitation calling hours
§ 64.1200(c)(1) restricts telephone solicitations to residential subscribers before 8:00 a.m. or after 9:00 p.m. local time at the called party’s location. Whether and how that maps to SMS is a fact-specific counsel question—do not assume SMS is exempt from all timing risk, and do not invent SMS-only hour rules not in the text. See the companion calling-hours draft.
What the FCC Does Not Run
- The Campaign Registry — industry/carrier registration hub for 10DLC
- Your CSP console — contractual AUP and filtering
- Short code leasing commercial processes — separate marketplace/program approval paths
FCC enforcement and private TCPA litigation are distinct from carrier filtering. You can pass Campaign review and still face TCPA claims if consent was defective—or fail Campaign review while having decent consent paperwork.
Business Compliance Program (Practical)
- Inventory every SMS template; tag marketing vs informational.
- Map each template to a consent standard and capture method.
- Retain audit trails (see consent audit trail draft).
- Honor STOP quickly; test HELP.
- Complete 10DLC Brand/Campaign registration for local A2P numbers.
- Monitor FCC rulemakings/FR notices for PEWC updates (example FR notice).
- Train staff not to paste promotional PSAs into “reminder” Campaigns.

Recordkeeping Expectations (Practical)
The FCC framework is enforced through complaints, investigations, and private litigation. Businesses that cannot produce consent records for a challenged text are at a disadvantage regardless of 10DLC status. Minimum practical packet:
- Consent language version history
- List source and timestamp
- Suppression / STOP logs
- Sample messages actually sent (not only TCR samples)
- Vendor process documents (who pushes send buttons)
Align retention with litigation hold policies and industry norms your counsel recommends—do not delete “old” opt-ins casually.
Relationship to Autodialer Debates
TCPA liability often hinges on whether a system is an “automatic telephone dialing system” under evolving case law and FCC interpretations. This article does not resolve ATDS definitions. Design consent as if marketing texts need PEWC, and ask counsel how ATDS risk applies to your specific platform—especially after major court decisions.
International Sending Note
FCC TCPA rules are US-focused. Messaging residents of other countries implicates other regimes (for example, consent rules abroad). If your “FCC SMS” program also texts Canada or the EU, add separate legal review; 10DLC registration alone does not address foreign law.
Coordination With Marketing Teams
Create a lightweight approval gate:
- New SMS template proposed
- Compliance tags marketing vs informational
- Consent standard assigned
- 10DLC Campaign mapping confirmed
- Only then enable in the app
This prevents “quick promo” edits that invalidate both TCPA posture and Campaign alignment. Link the gate to your opt-in requirements and disclosure pages.

FAQ
Where are FCC SMS regulations published?
Start with 47 CFR § 64.1200 on Cornell LII or the eCFR, plus related FCC orders and FR announcements. There is no separate “Part SMS.”
Are CTIA guidelines FCC rules?
No. They are industry best practices that often inform CSP expectations.
Do FCC rules replace 10DLC registration?
No. Different layers.
Can the FCC fine amounts be quoted here?
This article intentionally avoids inventing or casually repeating fine tables. Read primary FCC enforcement materials with counsel if you need penalty analysis.
