Missed call text back and TCPA consent: what a business owner needs to know

Texting someone who just called your business is usually treated as responding to their contact, which is different from sending them marketing. Even so, the safe setup is the same one you would use for any business texting: identify your business, keep the first reply about their call, honour STOP instantly, respect quiet hours, and keep a record. This post explains the shape of the rules. It is not legal advice, and your setup should be reviewed by counsel.

The rule everyone is asking about

The Telephone Consumer Protection Act (TCPA) is the U.S. law that governs automated calls and texts. Its consent requirements are strictest for marketing messages sent with automated systems. A text that says "we saw you called, how can we help" is, in most readings, a response to the customer's own contact rather than marketing. That is why missed call text back exists as a product category at all.

Two things follow. First, the reply should actually be a reply: about their call, not about a promotion. Second, "usually treated as" is not "always is", which is why the rest of this post is about staying conservative.

What the first text should and should not contain

Should: your business name, an acknowledgement of the call, one question about how to help. Should not: an offer, a discount, a link to a sale, or anything that reads as marketing. The moment the first text is promotional, you are in different territory.

STOP, HELP and identification

Whatever the consent analysis, the operational rules apply. Every text identifies the business. STOP is honoured immediately and remembered permanently for that number. HELP gets a reply that says who you are and how to reach a person. Our post on STOP, HELP and the texts you must answer covers the mechanics. Your platform should handle all three without the AI being involved.

Quiet hours

Outbound texts are generally restricted to between 8am and 9pm in the recipient's local time, and some states are stricter. An immediate reply to a call is one thing; a follow-up at 10pm is another. The conservative setting is one immediate reply and no further outbound until the morning.

Getting consent for what comes next

The missed-call reply starts a conversation. If you want to send that person reminders, review requests, or anything promotional later, get their consent for that, clearly, and record it. "Can we text you appointment reminders at this number? Reply YES" is enough for reminders. Marketing needs its own, separate consent. Do not treat a reply to a missed-call text as consent for everything.

Records

Keep the call log, the text, the reply, and any consent given, with timestamps. If a complaint ever arrives, the record is the whole defence. A platform that does not keep this for you is a platform to avoid.

Carrier registration

Separately from the TCPA, U.S. carriers require businesses that text from standard numbers to register through A2P 10DLC. Unregistered traffic is filtered or blocked. Our 10DLC guide covers registration; do it before the first text.

Frequently asked questions

Do I need written consent to text back a missed call?

Most readings treat a reply to the customer's own call differently from marketing, and consent requirements are strictest for marketing. Keep the reply non-promotional and honour STOP. Confirm with counsel for your situation.

What about callers who withheld their number?

There is no number to text, and no attempt is made.

Does this apply outside the U.S.?

Other countries have their own rules, some stricter. This post is about U.S. rules only.

What Frontiva does here

Frontiva's missed call text back is built and waiting on phone number provisioning. Its text back goes through the single send check every message uses (consent, opt-out, quiet hours, message purpose and frequency), and marketing-purpose sends are refused outright today. See transactional vs marketing texts for why the purpose matters.
