Quiet hours for business texts: what the 8 a.m. to 9 p.m. rule covers

What the rule says

The rule is 47 CFR 64.1200, issued by the Federal Communications Commission. We read the text. Paragraph (c)(1) says no person or entity shall initiate any telephone solicitation to:

• "Any residential telephone subscriber before the hour of 8 a.m. or after 9 p.m. (local time at the called party's location)."

Two things in that one line matter to a small business. The window is 8 a.m. to 9 p.m. And it is measured where the customer is, which is the part most often missed. The rule that sits beside it, about people who have asked not to be contacted, is covered in can a business call back a number on the Do Not Call list?

Does it apply to texts?

Yes. Paragraph (e) of the same rule says the rules in paragraphs (c) and (d) apply to anyone making "telephone solicitations or telemarketing calls or text messages to wireless telephone numbers."

So a promotional text is treated like a promotional call for this purpose. A text at 10 p.m. offering a tune-up special is on the wrong side of the line, however quiet a text may feel compared with a ringing phone. What every business text has to honor on the way out is in STOP, HELP and opt-outs.

Whose clock counts

The customer's: "local time at the called party's location." For a plumber whose customers all live in the same town, your clock and theirs are the same. It stops being simple when:

• You serve more than one time zone. An 8:30 p.m. text from Texas lands at 9:30 p.m. in Florida.
• The customer's area code is from somewhere else. People keep their numbers when they move. An area code tells you where the number was issued, not where the person is tonight.
• Software sends for you. A message scheduled for "9 a.m." goes at 9 a.m. on the server's clock unless the software is told otherwise.

If you are unsure where a customer is, the cautious choice is the narrower window: late morning to early evening is inside the rule nearly everywhere. Which hours get the best answer is a different question, covered in the best time to call a lead back.

What counts as a "telephone solicitation"

The time rule applies to telephone solicitations, and the rule defines the term. It "means the initiation of a telephone call or message" for the purpose of encouraging a purchase, and the definition says it does not include a call or message:

• "To any person with that person's prior express invitation or permission";
• "To any person with whom the caller has an established business relationship"; or
• "By or on behalf of a tax-exempt nonprofit organization."

Read plainly, the federal time-of-day line is aimed at sales messages to people who did not ask for them. That is narrower than many articles suggest. It is also only one rule. Other parts of the same law deal with consent for automated texts, the phone carriers apply their own standards to registered senders, and states have their own telemarketing laws, some stricter. We have not reviewed state laws for this guide and name none. What carrier registration involves is in what is A2P 10DLC.

The same window for phone calls

The Federal Trade Commission's Telemarketing Sales Rule has a matching line for calls. Section 310.4(c), which we read, makes it a violation, "Without the prior consent of a person," to call a person's home before 8 a.m. or after 9 p.m. in that person's local time. That section does not mention text messages; the FCC rule above is the one that does.

Two agencies, the same window. That is why a single habit covers both, and why your voicemail matters after 9: a caller you cannot ring back until morning should at least hear when you will. Wording is in what to say in a business voicemail greeting.

A safe habit for a small business

1. One window for everything automatic: no texts before 8 a.m. or after 9 p.m. in the customer's local time, whatever kind of message it is.
2. Hold, don't drop. A message that would go at 10 p.m. should go at 8 a.m., not be lost.
3. Ask for the ZIP code, not only the phone number, if you serve more than one time zone.
4. Answer late questions by hand if you choose to answer them at all, and keep the reply to what was asked.
5. Keep consent and opt-outs in order. Twilio's messaging policy, which we read, puts it this way: "A recipient must have the ability to revoke their previously provided consent at any time."
6. Check your state. If you do regular promotional texting, ask a lawyer whether your state sets a tighter window.

None of this slows down a good first response. A call missed at 9:40 p.m. answered at 8:00 a.m. is still a fast reply by most customers' standards: how fast a business should respond to a new lead.

How NewFrontDesk handles it

Our missed-call text-back is built around the same window. Its rules hold any text between 9 PM and 8 AM in the business's local time and send it at 8 AM; one text per caller in 24 hours; an opt-out list checked before every message. Those rules run today in test mode. Real texts are not switched on yet, so nothing is being sent to anyone.

What does work today is the web chat and the lead inbox, which take a late enquiry without sending anything to the customer's phone. The full picture is on the status board. To talk it through, call (346) 913-7215 or request setup.
