Partner: SMS Phone Numbers


Text messages are continuing to be a highly preferred method of consumer engagement for many businesses including within healthcare.  Mobile carriers (e.g. Verizon) have implemented a series of policies and procedures to increase trust across the messaging ecosystem and reduce the spam that consumers may receive through SMS messaging. These policies require phone numbers to go through a registration process to confirm who is sending the message, types of message contents and whether the consumer consented to receive these messages.

Types Of Phone Numbers 

There are 2 main number types used at Updox for practice to patient text messaging products such as Reminders, Video Chat invites, Secure Text, and Broadcast: 10 DLC and Toll-Free.

10 DLC (Local Number)

Sanctioned business text messages using a local phone number otherwise known as a 10-digit long code. To send messages using a 10DLC number, the business must register their brand, campaign content and be carrier approved.   

These can be helpful if you want to show your business locality (area code) to the customers.   


Sanctioned business text messages using a toll-free number which is a ten-digit number starting with 8XX such as 800, 877, 888, etc. All traffic through toll-free numbers needs to go through a verification process and gain carrier approval.   

While a toll-free number does not have the same tie to locality, it provides a lower cost method of sending SMS messages.

Registration Processes 

Each number type will undergo a different registration process. For 10 DLC numbers, a campaign will need to be registered and approved by the carriers. For Toll-Free numbers, they will need to be verified by the carriers. Updox will complete the number registration on your behalf once we have collected all necessary business details.   

10 DLC (Local Number)

Use of a 10 DLC number requires the submission of a campaign to the carriers. The campaign requires details such as business name, address, phone number, contact, email, company website, and EIN (What is an EIN?). Along with business details, the campaign requires examples of message contents and end user consent. This also requires a one-time campaign registration fee of $25 as well as monthly campaign fees of $12 per number.  


Use of a toll-free number requires the number to go through a verification process with the carriers. The verification requires details such as business name, address, phone number, contact, email, and company website. There are no additional fees for verifying a toll-free number.   

How do I know if I am impacted? 

Partners that are impacted by this change would those who are leveraging either of the two API’s listed below to send SMS messages 

  • EventNotificationBulkCreate

  • SMS Send

If any of your customers have contracted directly with Updox to leverage our SMS based products we will be working directly with those customers to aid in the verification process.  

HEADS UP! In addition, if you are leveraging our Broadcast or Reminders products inside of the Updox application you may also be impacted.

What do I need to do?

Over the next several weeks we will be working directly with our partners who are leveraging our SMS API’s or SMS based products to better understand what type of messages your customers may be sending through our API’s or products and with that information come up with recommendations and best practices to aid in developing a strategy to help with message delivery and phone number verification processes.
