If you are a SaaS platform, ISV, or marketing agency, you may send messages on behalf of multiple businesses. A common question is:
Can I use one 10DLC or Toll-Free number for all my clients, or does each client need their own registration?
The answer depends on one key factor: who the message appears to come from.
Quick Answer
You may use ONE registration
if the message is sent as your platform and your platform is the visible sender.
Each client needs their own registration
if the message is sent as your client’s business and that business is the visible sender.
Visual Decision Flow
Your Platform
Examples:
- Reminder: You have an appointment tomorrow at 2 PM.
- Your booking is confirmed. Manage it in the app.
- You have a new notification. Log in to view.
Result: One 10DLC / Toll-Free registration may be enough.
Your Client’s Business
Examples:
- ABC Salon: Your appointment is tomorrow at 2 PM.
- XYZ Gym: Get 20% off your membership today.
- Dr. Smith: Your lab results are ready.
Result: Each client must have their own 10DLC or Toll-Free verification.
When You Can Use One 10DLC / Toll-Free Number
You can usually use one registered number when:
- Messages are sent as platform notifications
- Your platform is the primary sender
- The content is generic or system-generated
- Users opted in to receive messages from your platform
Reminder: You have an appointment tomorrow at 2 PM.
Your booking is confirmed. Manage it in the app.
You have a new update. Log in to view your account.
In these cases, the platform is the sender, and the business is either not shown or is secondary.
When Each Client Must Be Registered
Each client needs their own registration when:
- The message includes the client’s business name as the sender
- The customer opted in to receive messages from that business
- The message is clearly sent on behalf of that business
ABC Salon: Your appointment is tomorrow at 2 PM.
XYZ Dental: Please confirm your appointment.
Main Street Fitness: Join today and save 20%.
In these cases, the end user sees the business as the sender, not the platform.
Examples by Business Type
SaaS / ISV Example
If you are a software platform whose customers also have their own customers:
One registration may work if:
- Messages are neutral system notifications
- Your platform is the visible sender
- Branding stays platform-centric
Separate registrations are needed if:
- Messages are branded for each customer business
- Your customers text their own end users under their own brand
- The customer relationship belongs to the business, not the platform
Marketing Agency Example
If you run campaigns for multiple business clients:
- You cannot use one number or one campaign for all brands
- Each business must be registered separately
Not allowed on a shared campaign:
- ABC Gym: Join today and save 20%.
- Bella Spa: Book your facial this week.
- Downtown Dental: Schedule your cleaning.
