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: Under 47 CFR § 64.1200(c)(1), telephone solicitations to residential subscribers may not be made before 8:00 a.m. or after 9:00 p.m. local time at the called party’s location. The rule is written for telephone solicitations—not as a standalone “SMS hours” statute. Whether your texts are treated like covered solicitations is fact-specific; many businesses still adopt 8am–9pm recipient-local policies as a risk control and must check stricter state rules.
Worked example: scheduling texts around calling-hour rules
A national retailer schedules a promotional text for 8:30 p.m. Eastern. That is fine in New York, but it would land at 5:30 p.m. Pacific and 7:30 p.m. Central, within the TCPA's 8 a.m. to 9 p.m. window everywhere. However, Florida and Oklahoma restrict marketing texts to 8 a.m. to 8 p.m. local time, so the send would violate both states' laws for subscribers there.
The retailer switches to time-zone-aware scheduling based on the subscriber's area code and address, applies the stricter state windows, and sends the campaign at 11 a.m. local time instead.
What the Federal Rule Says
§ 64.1200(c)(1) restricts initiating telephone solicitations to residential telephone subscribers outside the 8:00 a.m.–9:00 p.m. window, measured in the called party’s local time—not the caller’s headquarters time zone.
Key ideas:
- Telephone solicitation is a defined concept in the TCPA/FCC framework (generally purchase/rental/investment pitches, with exclusions such as prior express invitation/permission or established business relationship contexts as defined in the rules). Read the current definitions in § 64.1200 rather than marketing slang.
- Residential subscribers are the protected class named in this paragraph.
- Local time of the called party drives compliance—area-code heuristics help but fail after number portability; better to store timezone or postal locality when possible.
Use Cornell LII or the eCFR Subpart L for the living text.
Do Calling Hours Apply to SMS?
The regulatory text of (c)(1) addresses telephone solicitations, historically voiced around calls. Businesses and litigants sometimes dispute how timing theories apply to texts. This article does not invent a bright-line FCC “SMS must follow 8–9” sentence that is not clearly universal.
Practical risk management many programs use (policy choice—validate with counsel):
- Apply recipient-local quiet hours to marketing texts similar to voice solicitations
- Allow transactional/care messages under separate rules agreed with counsel (appointment reminders may be treated differently than promo blasts)
- Log timezone logic for audits
- Review state telemarketing laws that may impose earlier evening cutoffs or other limits
Building a Send-Time Control
| Control | Implementation note |
|---|---|
Store recipient_timezone |
From address, explicit preference, or verified locale—not only NPA |
| Default window | 8:00–21:00 local as a federal-aligned baseline for solicitations |
| State overlays | Configurable earlier cutoffs where required |
| Message class | marketing vs transactional flags gate which window applies |
| Queue, don’t drop | Hold marketing sends until window opens |
| Agent tools | Block manual promo dials/texts off-hours |
Common Operational Mistakes
- Using company HQ time for a national list
- Assuming area code = timezone after porting
- Treating STOP compliance as a substitute for hour restrictions
- Sending “flash sale” texts at 6 a.m. local because the batch job started in UTC
- Ignoring state-level rules because federal 9 p.m. “felt fine”
Relationship to 10DLC Registration
Quiet hours are a TCPA/state timing issue. TCR/10DLC registration does not set your clock. You can have an approved Campaign and still create timing risk with off-hours marketing blasts.
Consent still comes first—see consent evidence trail and PEWC/opt-in drafts in this series. Tools on MyTCRPlus help with registration packaging, not courtroom timing strategy.
Examples (Illustrative Only)
- A national retailer queues promo voice calls using area-code timezone tables with a 30-minute buffer inside 8–9—still verify ported numbers.
- A clinic sends appointment reminders at 7:30 a.m. local under a counsel-approved informational policy separate from solicitation dialers.
- A lead-gen SMS tool blocks marketing robotexts outside 8–9 recipient-local by default; transactional OTP may use a different policy.
These stories are patterns, not safe harbors. Configure systems explicitly; do not rely on “everyone does 8–9 for SMS” folklore without counsel sign-off.
Documentation for Audits
Keep:
- Policy PDF stating windows by message class and state overlays
- System screenshots of timezone logic
- Change log when windows update after FR/state law changes
- Exception approvals (rare) with legal sign-off
Tie this file set to your broader TCPA consent program so timing and consent evidence live together.

FAQ
Is it illegal to call at 9:30 p.m. local?
Initiating a telephone solicitation to a residential subscriber after 9:00 p.m. local (or before 8:00 a.m.) conflicts with § 64.1200(c)(1). Non-solicitation calls may fall outside that paragraph—classify with counsel.
Does 9:00 p.m. mean I can start a call at 8:59?
The rule prohibits initiating outside the window. Do not cut it close; systems should use inclusive safe buffers.
What about texts at 10 p.m.?
Treat marketing texts as high scrutiny; adopt conservative quiet hours and confirm with counsel whether additional theories apply. Do not claim a universal SMS exemption from all timing risk.
Whose clock if the customer travels?
Best efforts using the number’s associated locale/preference; document your method. Perfect knowledge is hard—policies and counsel guidance matter.
Do nonprofits get different hours?
Consent and solicitation definitions include specialized provisions elsewhere in § 64.1200; do not assume a blanket hours exemption without reading the rule with counsel.
