What is A2P 10DLC?

A2P 10DLC (Application to Person Ten Digit Long Code) is a system being introduced which 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 in 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 10DLC's 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) which 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, to 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?

Registering 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 is a TCR Trust Score?

A TCR Trust Score is the score that is allocated to a Brand once the registration process has been completed. This score will either be High, Medium or Low, and influences various factors like the Brand's messaging throughput. The score is calculated by using a reputation algorithm to review specific criteria relating to your company. This means it's important to ensure the information you provide to SMSGlobal is accurate when registering your brand.

How does the Trust Score impact my throughput?

US operators allocate throughput and limits based on a message class which is determined by the Trust Score allocated to that brand. AT&T and T-Mobile provide different limitations based on the message class. AT&T provide different TPM (Text per minute) for Campaigns while T-Mobile provide a daily cap for a Brand.


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

Below table 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.

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