10DLC Advantages

Proper registration and use of 10DLC has many advantages over unregistered texting.

Enhanced Deliverability

Most of our customers are seeing 95%+ delivery for registered texts -- significantly higher than unregistered traffic.

Carrier Troubleshooting

When issues arise with carriers, we are able to work directly with Campaign Registry and the carriers to resolve delivery issues.

Reduced Network Access Fees

In most cases, registered traffic is charged a lower per-segment network access fee compared to unregistered traffic.

What is 10DLC?

10DLC refers to carrier imposed rules, regulations and technology designed to sanction and vet SMS and MMS messages sent via 10 digit local long code phone numbers within or to the United States. The objective of 10DLC is to protect consumers from unwanted messages while offering organizations higher throughput and delivery rates.

When do I need to be registered?

All 10DLC needs to be registered by March 1, 2022. Unregistered traffic sent after March 1, 2022 may be heavily filtered, subject to high per-message surcharges, or even fined. Prompt.io will only be serving registered traffic after March 1, 2022.

Who Needs 10DLC?

Sending texts over standard phone numbers (202-555-1212, 310-555-1212) in the United States requires 10DLC registration. Texting outside of the United States (Canada, for instance) does not require 10DLC registration at this time.


Each organization wishing to text on 10DLC will need to be registered. All registration is controlled by a carrier-led entity known as The Campaign Registry. Prompt.io is a partner of The Campaign Registry and in most cases, we will be facilitating your organization's registration.

In order to register, you will need to provide information about your organization, including your EIN, use cases, sample messages, and responsible contacts. Your account manager and onboarding team will ensure that your organization gets properly set up.


There is a small one-time fee for registration. Additionally, there are quarterly fees associated with an organization's use case -- typically between $6 and $30 per quarter. In most cases, Prompt.io will pass these through to customers. We will communicate clearly with you regarding registration and work with you to ensure compliance regarding new rules and regulations.

As of March 1, 2022, AT&T is increasing the unregistered outbound network access fees for both SMS (from $0.002 to $0.004) and MMS (from $0.0035 to $0.005) per message segment. Network access fees for registered traffic will remain the same: $0.002 for SMS, $0.0035 for MMS. On this same date, T-Mobile has indicated that they will also be increasing network access surcharges for inbound and outbound SMS (from $0.003 to $0.004) and MMS ($0.01 to $0.013) traffic. Registered traffic on T-Mobile will remain at $0.003 and $0.01 for SMS and MMS respectively. Additionally, T-Mobile will be implementing a one-time $50 registration fee for getting an organization up and running with 10DLC. Register your organization before March 1, 2022 in order to avoid this one time charge.

Messaging Restrictions

Upon registration, your organization will be given a vetting score known as a RISQ score (Routine Information and Services Quality) based on your organization's profile and use case. Maximum throughput and daily limits on the number of texts that can be sent can be dependent on this score. Throughput can be up to 30 times faster than the limits that were typical prior to the arrival of 10DLC. While for some use cases there may be daily limits imposed, 10DLC will mostly alleviate any need for multiple outbound phone numbers -- vetted traffic will get very high deliverability.

As of March 1, 2022, throughput for unregistered texts will be severely degraded.

Toll Free, Short Code

10DLC has no impact on toll free or short code traffic. If your organization utilizes these types of texting channels, there is no need to register.

For Our Bring-Your-Own Twilio Customers

For our customers that are currently bringing their own Twilio credential, we offer two paths forward:

  1. Transition to Prompt.io provided messaging. We now offer turnkey messaging where you do not need a Twilio credential to text. In these cases, Prompt.io can facilitate your transition from Twilio as well as registration of your traffic. This is the preferred path forward -- our text messaging is far more reliable and we can provide 1st class support in cases where any issues arise.
  2. Utilize Twilio's Trust Hub to register your organization with The Campaign Registry via Twilio. We have built an upgrade path in our Twilio integration that ensures that your Twilio account is configured properly if you use Twilio's Trust Hub for registration. Your account manager or customer support can help you with this process.


In some cases, it may make sense to transition to texting via toll free rather than register for 10DLC. Your account manager will work with you to determine if this is a viable path forward for your organization. Note that use of toll free requires iron-clad opt-in and is not suitable for political texting.

More Information

For more information, please contact support or your account manager or download the 10DLC flyer provided above. Know that we are here for you in this transition and will help you ensure that your organization complies with the new requirements.
