Glossary
Brand
In SMS business messaging, a “Brand” refers to the business or legal entity that is sending messages to consumers. Think of it as the official identity behind the communication. Whether you’re a mom-and-pop shop or a global giant, your Brand must be registered for compliance.
Campaign
A “Campaign” is a specific messaging program or purpose under which you send messages. For example: promotions, appointment reminders, order updates, etc. In the SMS compliance world, every Campaign needs a defined scope — no freestyling allowed.
Short Code
A Short Code is a 5–6 digit phone number (like “12345”) used to send and receive high-volume SMS/MMS messages. It’s memorable, fast, and expensive (but worth it for brands needing mass reach and reliability). Learn more about Short Code, its use case, pros and cons, click our article on Short Code 101.
10DLC (10-Digit Long Code)
10DLC stands for 10-Digit Long Code — basically, a standard-looking local phone number (e.g., 555-123-4567) specifically registered and approved for business messaging. It’s the cost-effective, regulation-friendly solution for businesses that don’t need Short Code-level scale.

TFN (Toll-Free Number)
A TFN (Toll-Free Number) is a familiar number beginning with 800, 888, 877, etc., that allows consumers to text or call without paying charges. Businesses often use TFNs to combine voice calls and messaging into one easy-to-remember number. Learn more about TFN, its use case, pros and cons, click our article on TFN 101.

Compliance Checklist
1. Messaging Content Requirements
- Ensure all messages align with current mobile operator policies.
- Stay up to date—regulations change frequently.
2. Call-to-Action (CTA) Requirements
All campaigns must have a visible, compliant CTA prior to opt-in. The purpose of a CTA is to ensure the Consumer consents to receive text messages and understands the nature of the program.
Sender’s must include:
- Brand Name or Program Description
- Message Frequency Disclosure
- “Message & Data Rates May Apply” (except for FTEU)
- STOP keyword (opt-out info)
- Terms and Conditions (link or full text; no popups)
- Privacy Policy (link or full text)
Â
Please also note that:
- The CTA must be accepted by the end-user prior to receiving messages on their handset. Contact us at AskVT@vvpusa.net if you are interested in using our patented technology VORTxT to obtain the opt-in with indisputable evidence automatically and at scale.Â
- Opt-in from the consumers must be optional instead of required for consumers.
Be sure to include the exact verbiage that is listed on the website/marketing materials when you submit your sender request

1. Opt-In Confirmation:
The message must Include:
- Program name
- Message frequency
- Customer care contact
- Opt-out instructions
- “Message & data rates may apply”
- See our example here: “

- Program name

3. STOP Message
When users opt-out, brands should:Â

5. Terms and Conditions Page
Terms and Conditions can appear directly below the CTA or be linked nearby. Must include:
- Program/Brand Name
- Description of product or service
- Message frequency
- Message & Data Rate Disclosure
- Customer support contact
- Opt-out instructions
6. Privacy Policy
Message Senders must protect consumer data and follow all applicable privacy laws. Privacy policies should clearly state that SMS opt-in data will not be sold, rented, or shared. If data sharing is mentioned elsewhere in the policy, include a specific clause that SMS data will not be shared. The privacy policy must be available at the point of opt-in (CTA). Sender’s Privacy Policy must:
- Be accessible from the CTA (opt-in)
- Clearly state that SMS opt-in data is not sold, shared, or rented
- Comply with applicable privacy laws
7. Deactivated Phone Numbers
Registration Processes
A deactivated number is one that’s been disconnected by the carrier—often due to the user switching providers or closing their account. These numbers are eventually recycled and reassigned, meaning you could accidentally message someone who never opted in. Understanding how deactivated numbers work is key to avoiding compliance risks.
Sending messages to recycled/deactivated numbers can result in:
- Fines up to $1,500 per message
- Potential class action lawsuits
Use our Deact Reports to keep contact lists updated and avoid penalties. For Deact Report inquiry, please contact us via: Report@vvpusa.net
