Using non-compliant SMS for your gym could cost you big – blocked messages, hefty fines, and lost trust. Starting February 1, 2025, U.S. carriers began blocking unregistered 10DLC (10-digit long code) messages. This means gyms not following the rules will face major disruptions in member communication.
What’s the solution? Register your SMS campaigns under 10DLC. This ensures:
- Better message delivery
- Faster sending speeds (up to 75 messages per second)
- Lower legal and financial risks
- Improved member trust through opt-ins and clear opt-outs
Non-compliance risks include:
- Messages blocked by carriers
- TCPA fines ranging from $500 to $1,500 per violation
- Damaged reputation and member dissatisfaction
Bottom line: Switching to 10DLC-compliant SMS is no longer optional. It’s the only way to maintain consistent communication and avoid penalties. Platforms like RevText can simplify the process by handling registration, consent tracking, and compliance monitoring.
10DLC Compliance Best Practices: What You NEED to Know
What is 10DLC-Compliant SMS?
10DLC, or 10-Digit Long Code, is a structured system for business-to-consumer SMS messaging in the United States. These numbers act as local SMS endpoints, making them ideal for businesses like gyms. Using a familiar local number can improve member engagement and foster trust with your audience.
To comply with 10DLC, businesses must register their brand and SMS campaigns with The Campaign Registry. This process helps confirm the legitimacy of businesses and reduces spam and fraud in messaging.
One standout feature of 10DLC is its trust score system. Carriers assign a trust score to each campaign, which directly impacts message throughput and delivery rates. For instance, a properly registered gym can send up to 75 messages per second, compared to just 1 message per second with traditional long codes.
Let’s break down the compliance rules gyms need to follow.
Core 10DLC Compliance Rules
To meet 10DLC standards, gyms must adhere to several key requirements. First, they need to obtain explicit opt-in consent from members before sending any messages. Every message must also include clear opt-out instructions, such as "Reply STOP to opt out", to allow recipients to unsubscribe easily.
Additionally, content restrictions under the S.H.A.F.T. rule prohibit messages that include references to sex, hate, alcohol, firearms, or tobacco. During registration, gyms must provide accurate business details, including their legal name, address, tax ID, and a thorough description of their SMS campaigns. Any inaccuracies in this information can lead to suspension. Finally, maintaining detailed records of member consent and campaign activity is essential for audits or legal defense.
These rules not only ensure compliance but also offer practical benefits, as outlined below.
Why 10DLC Helps Gyms
Following 10DLC guidelines offers more than just regulatory compliance – it improves overall communication. Registered messages are less likely to be flagged or blocked by carriers, ensuring members receive important updates about class schedules, membership renewals, or special promotions. The faster message throughput also allows gyms to reach large audiences quickly, especially during high-demand periods like New Year’s promotions or unexpected closures.
Compliance also reduces legal risks by aligning with federal regulations and carrier policies, helping gyms avoid fines or lawsuits. Plus, when members receive messages they’ve opted in for – and can easily opt out of – it builds trust and strengthens loyalty.
While registration can take up to four weeks due to carrier reviews, the effort pays off. Compliant gyms benefit from more reliable message delivery, reduced legal exposure, and secure operations. By embracing 10DLC standards, gyms can enhance their communication strategies and protect their business from unnecessary risks.
Risks of Non-Compliant SMS
Gyms that fail to comply with 10DLC regulations face serious challenges. Starting February 1, 2025, major U.S. carriers will block all unregistered SMS traffic. This means gyms that don’t adhere to these rules will lose a reliable way to communicate with their members.
Legal and Business Risks
When unregistered numbers are blocked, essential messages – like class reminders or promotional updates – won’t reach members. This kind of disruption can hurt operations and member engagement.
Beyond service interruptions, gyms also risk penalties under the Telephone Consumer Protection Act (TCPA). The TCPA imposes fines ranging from $500 to $1,500 per violation, depending on whether the violation is deemed accidental or intentional. For example, sending one unauthorized promotional message to 1,000 members could result in fines totaling $500,000 to $1.5 million. Additionally, members who receive messages without giving consent may file lawsuits, leading to costly settlements and legal expenses that can strain a gym’s budget.
Repeated violations could result in even harsher consequences, such as being blacklisted by carriers. This would permanently cut off a gym’s ability to use SMS for marketing or member communication. Regaining SMS privileges after being blacklisted is no small feat – it requires extensive proof of compliance and a lengthy review process.
Non-compliant messages are also more likely to be flagged as spam, which can harm your sender reputation. Once damaged, it becomes much harder to maintain effective communication with members. These risks underscore the importance of following 10DLC guidelines carefully.
Damage to Member Trust
The fallout from non-compliance isn’t just legal or operational – it can also erode trust. Members who receive unsolicited or excessive messages often view them as spam or intrusive. This can lead to unsubscribes, membership cancellations, or even negative reviews.
As word spreads, potential new members may hesitate to join a gym that appears to disregard privacy and communication standards. When critical messages like class schedules, special offers, or event invitations fail to reach members, engagement drops. This lack of communication can lead to reduced attendance, ultimately threatening the gym’s long-term success.

10DLC vs. Non-Compliant SMS: Side-by-Side Comparison
For gym owners, choosing the right messaging strategy is more than a technical decision – it directly affects daily operations, member satisfaction, and business growth.
10DLC compliance requires proper registration and member opt-ins, ensuring transparent and regulated communication practices. On the other hand, non-compliant SMS skips these formalities, often bypassing registration and consent, which can expose businesses to operational and legal risks.
One key distinction lies in message speed. Registered 10DLC numbers can send up to 75 messages per second, while unregistered long codes are limited to just 1 message per second. This difference can significantly impact a gym’s ability to deliver time-sensitive updates, like last-minute class changes or promotions. Here’s a detailed comparison:
Comparison Chart
| Factor | 10DLC-Compliant SMS | Non-Compliant SMS |
|---|---|---|
| Compliance Rules | Requires registration, opt-in, opt-out, and record-keeping | No formal registration or proper consent |
| Delivery Rates | High – messages are pre-approved by carriers | Lower – messages often blocked or filtered |
| Legal Risks | Minimal when following guidelines | High risk of fines, blocks, and legal action |
| Business Continuity | Reliable and predictable service | Prone to sudden service interruptions |
| Message Speed | 1–75 messages per second | About 1 message per second |
| Costs | Predictable fees with registration and standard rates | Higher per-message fees and penalties |
| Member Experience | Messages are trusted and consent-based | Higher risk of spam complaints and distrust |
| Sender Reputation | Builds credibility with carriers | Risk of blacklisting and damaged reputation |
While 10DLC may involve upfront registration fees, it offers predictable costs and avoids the hidden expenses of non-compliant messaging – such as higher per-message charges and potential fines .
Beyond cost, compliance fosters trust. With 10DLC, members receive messages they’ve explicitly opted into, reducing spam complaints and improving relationships. In contrast, non-compliant messaging can lead to frustration and erode member trust, which may hurt retention efforts.
For gyms, 10DLC provides a reliable and cost-effective communication channel. By contrast, non-compliance not only risks service interruptions but also incurs unpredictable expenses. This has become even more critical as carriers have tightened restrictions on unregistered traffic since February 2025 .
