If you’ve ever tried texting customers in the U.S., you probably expected it to work as easily as sending a message to a friend. You type it, hit send and think everything will land on time. But in some cases, the messages never go out. They just disappear. You refresh the dashboard, check your credits and wonder what went wrong. Most people don’t realize that certain industries simply can’t use a text messaging service in the United States. The system blocks them before anything even moves.
It feels odd at first. You might think, “Why would texting be an issue if I’m running a legal business?” But carriers in the U.S. follow strict rules. They look at which industries have caused the most issues, scams and complaints over the years. If your business fits one of those categories, your messages won’t pass through, even if your intentions are clean. We deal with this often at ExpertTexting, so you’re definitely not the only one who bumps into it.
It all comes down to risk. So instead of approving everyone, carriers draw a line. When you use a text messaging service, your messages go through filters. If the content or industry matches a restricted list, the filters stop it. Carriers don’t ask why. They don’t warn you. They just block the traffic.
Even businesses that follow all legal rules still get blocked if they fall under a risky category. Carriers look at national behavior, not individual companies. So even if your brand is solid, you’re affected by the overall reputation of the category.
Here’s a simple breakdown of the industries that usually run into messaging barriers. No complicated explanations, just the basics you actually need to know.
Anything tied to cannabis or CBD gets blocked. Even if your state allows it, carriers treat it as a controlled product nationwide. So promotions, reminders or any mass texting connected to it won’t reach customers.
This category is also restricted. If your business sells guns, ammo or related gear, promotional texting won’t be approved. Carriers avoid it due to safety regulations.
Sports betting and gambling create a lot of complications across states. Texting adds more confusion, so carriers take the safe route and block it altogether.
A lot of scams started in this category back in the day, and the damage stuck. Carriers still block marketing messages tied to debt help or loan adjustments.
Collectors have legal contact rules to follow, and texting often crosses those limits. That’s why carriers stop most campaigns from this category, too.
Crypto messages have caused all kinds of problems, so carriers block promotional texts tied to trading, token sales or anything investment-related.
Since many of these offers turned out to be misleading, carriers block this category entirely. Even genuine businesses get caught in the filter.
This includes topics related to Sex, Hate, Alcohol, Firearms and Tobacco. If your marketing touches any part of this group, texting won’t be approved.
When you sign up for A2P sender registration, carriers review your business info and message samples. If your industry falls on the restricted list, the registration is denied right away.
But even if you somehow pass the first step, the content is still scanned every time you send a message through a text messaging service. If something in the text triggers a filter, it blocks your campaign before it reaches anyone.
Too many violations can lead to penalties or suspension. That’s why we always tell senders: don’t test the system, it doesn’t take risks lightly.
If your category is restricted, you still have a few options. You can send neutral, non-marketing content in some cases. For example:
These must be plain and direct. No discounts, no persuasive lines and no sales language. Anything promotional gets flagged immediately. For marketing, you might need to rely on email, social media or actual phone calls.
You should also keep solid consent records. If you ever operate in a grey-area category, having proof of consent helps avoid message filtering. It doesn’t fix every issue, but it reduces the problems.
Message filters exist to keep texting safe. When risky industries send mass texting, complaint rates rise, and carriers tighten their filters even more. That hurts everyone. So by staying compliant, you protect your delivery rates and keep your audience from getting frustrated.
At ExpertTexting, we try to make the rules easier to follow so you don’t deal with blocked messages, penalties or damaged sender reputation.
Texting is easy for most industries, but it gets complicated when your business falls under a high-risk category. The U.S. takes consumer protection seriously, so carriers restrict promotional messaging to avoid fraud, sensitive content and safety issues. If your business falls into any of the restricted groups, you’ll need alternate ways to communicate and keep your message strategy clean.
Text messaging service still works well for many businesses, but only when you follow the rules that keep the system safe.

1. Why are some industries blocked from texting?
Because they show higher fraud or complaint rates.
2. Can a restricted industry appeal the block?
Approval is unlikely. Carriers rarely make exceptions.
3. Do all carriers follow the same rules?
Most of them do, so switching providers doesn’t solve the issue.
4. What happens if I ignore the restrictions?
Your messages get blocked, and your account may face penalties.
