10DLC for A2P Messaging

What is Application to Person 10-Digit Long Code (A2P 10DLC)?

A2P text messaging is any business SMS sent from an online platform or application. Previously, traditional ten-digit mobile numbers were restricted to P2P (Person to Person) messaging. With new regulations in the US, businesses can now register SMS campaigns and send A2P messages from a standard local number—10DLC.

Why use A2P 10DLC?

10DLC is the new normal for A2P messaging

In the past, sending A2P messages in the US was limited to Short Code and Toll-Free virtual numbers. Now, you can send low-cost A2P SMS from a traditional US mobile number when you use Ten Digit Long Code (10DLC). Use a familiar and recognizable mobile number for your brand. Select from a variety of SMS use cases and register your campaign to start sending with A2P 10DLC.

Send enterprise SMS from an online gateway with A2P 10DLC, the new normal in the US.

Frequently Asked Questions For 10DLC

Your 10DLC FAQs Answered

Addressing some of the common questions related to the new A2P 10DLC changes. For more information, visit the SMSGlobal Knowledge Base

  • What is A2P 10DLC?

    A2P 10DLC (Application to Person Ten Digit Long Code) is a system being introduced that enables businesses to send A2P messages over a sanctioned channel that is approved by US carriers.

  • What are the advantages of A2P 10DLC?

    A2P 10DLC allows for improved quality for message delivery as all messages are pre-approved and registered. This also means the traffic will be less prone to filtering by US carriers which was a common scenario with P2P messaging (Person to Person) in the past.

  • What do I have to do to send over A2P 10DLC?

    A2P 10DLC has already been activated on the Verizon network since 2019 with no additional requirements other than to procure your own 10DLC. However, both AT&T and T-Mobile have introduced registration requirements which users of 10DLCs would need to go through in order to start sending.

    Registration of both the user's Brand as well as their Use Case will need to be submitted to AT&T and T-Mobile for review and approval before messages can be sent. You can start this process by providing SMSGlobal with details relating to your Brand and Use Case.

  • What is a campaign use case?

    Carriers define a campaign as a messaging use case, which includes sending delivery notifications and security alerts, as well as marketing messages. Some brands will need to register one campaign use case, while others may have to register multiple. Talk to our Customer Success team for more information on Dedicated and Mixed campaigns, and the campaign use case options.

  • What is SMSGlobal's role in A2P 10DLC?

    SMSGlobal is an officially registered CSP (Campaign Service Provider) that facilitates the registration of a company’s brand and campaign(s). We submit this information to the TCR (The Campaign Registry) which was formed by US carriers to regulate the telecommunication industry for A2P 10DLC.

  • What if I send A2P 10DLC without registering my brand and campaign?

    The result will vary based on the operator, but AT&T has plans to block traffic that is not properly registered starting 1st of June. We recommend all customers who send over a 10DLC with SMSGlobal, have their brand and campaign registered to ensure reliable delivery of their messages.

    Note: Carriers have extended a 30-day grace period to ensure you have ample time to register your Brand and Use Case. We suggest you register as soon as possible to avoid any disruptions. Unregistered campaigns run the risk of messages going undelivered and being blocked.

  • Are there any costs to register my brand and campaign for 10DLC?

    The Campaign Registry has introduced costs to register brands and campaigns, and pricing varies by the operator. SMSGlobal may incorporate these costs into our standard 10DLC pricing. Please get in contact with us for more information regarding these costs as they are subject to change.

  • How long does the registration process take?

    Submitting your details only takes a few minutes. However, the time to get a brand and campaign approved typically takes 1-3 business days. This can be shortened or lengthened depending on whether we have all the information required and it is accurate.

  • What are the different A2P 10DLC message classes and allocated limits?

    The table below references the limitations imposed by US carriers based on the TCR Trust Score. Once a brand is registered and approved on the TCR, a score will be allocated based on various criteria related to that brand. The score will determine the throughput and limits available to that brand and campaign, and are preset by the US operators like AT&T and T-Mobile. Operators may change these in the future.

  • Is MMS messaging affected by A2P 10DLC?

    Yes, MMS campaigns will also need to be registered with the TCR and US operators.

  • Is Canada also influenced by these regulation changes?

    No. Canada is currently not adopting the same rules and regulations as the USA for A2P 10DLC. Canadian operators may introduce their own A2P solution in the future.

  • Once I am verified, how can I send higher throughput?

    SMSGlobal can have your brand submitted for vetting through an external vetting partner. Brands that are vetted can have access to all standard use cases and potentially achieve higher messaging throughput.
