Why Your Practice Needs 10DLC Registration for Patient Messaging
If you've recently set up a dedicated phone number for your practice through Formisoft, you might have noticed a note about "10DLC registration." It sounds technical, but it's actually straightforward — and it's designed to protect your patients.
What is 10DLC?
10DLC stands for 10-Digit Long Code. It's a registration system required by US carriers (T-Mobile, AT&T, Verizon) for any business that sends text messages using a standard 10-digit phone number.
Before 10DLC, anyone could buy a phone number and blast thousands of spam messages. Carriers had no way to tell the difference between a legitimate appointment reminder from your practice and a spam text selling fake insurance.
10DLC fixes that. When you register, carriers know:
- Who you are — a real healthcare practice
- What you're sending — appointment reminders, intake forms, follow-ups
- That your patients opted in — they gave consent to receive messages
Why does it matter for your practice?
1. Your messages actually get delivered
Unregistered numbers get filtered aggressively by carriers. T-Mobile in particular blocks most unregistered business messages outright. With 10DLC, your appointment reminders, intake form links, and follow-up messages reach your patients reliably.
2. Higher sending limits
Registered numbers can send significantly more messages per minute than unregistered ones. If you're sending reminders to 50 patients for tomorrow's appointments, you need that throughput.
3. Patient trust
Messages from registered numbers are less likely to be flagged as spam on your patients' phones. That means fewer patients miss their intake forms or forget their appointments because the message got buried.
4. It's the law
Since February 2025, unregistered 10DLC traffic is blocked entirely on major US carriers. This isn't optional — it's a requirement for any business sending SMS.
What Formisoft handles for you
When you provision a dedicated phone number through Formisoft, we handle the 10DLC registration automatically:
- Brand registration — We register your practice as a verified business with the carrier networks
- Campaign registration — We register the types of messages you'll send (appointment reminders, intake forms, patient notifications)
- Number assignment — We link your phone number to the approved campaign
The whole process typically takes 1–5 business days for carrier approval. During that window, some messages may not deliver to all carriers. Once approved, everything works reliably.
What you need to do
Nothing. Formisoft handles the entire registration process. Just:
- Go to Settings → Phone Number
- Find and select a number for your practice
- Start sending — we take care of the rest
If you notice messages not delivering in the first few days after getting a new number, that's normal. Carrier approval is in progress and your messages will start going through once it's complete.
FAQ
Q: Do I need to register each time I send a message? No. Registration is a one-time process per phone number. Once approved, it stays active as long as you keep the number.
Q: Does this apply to emails too? No. 10DLC is only for SMS/text messaging. Email is handled separately through our email infrastructure.
Q: What if my messages aren't delivering after 5 days? Contact us. In rare cases, carrier approval can take longer or require additional verification. We'll sort it out.
Q: Can patients still reply to my messages? Absolutely. 10DLC registration doesn't change how two-way messaging works. Patients can reply, and their responses show up in your Formisoft inbox.
Setting up patient messaging shouldn't be complicated. We built Formisoft to handle the technical details so you can focus on what matters — taking care of your patients.
