This overview and FAQ represents Bandwidth's most current understanding of mobile carrier plans to introduce additional requirements and fees for sending messages using local phone numbers intended for their respective mobile carrier subscribers. Many of these details are still being finalized, but we'll continue to update this article as we learn more or as mobile carrier requirements change.
Certain mobile carriers are adjusting the throughput caps they've historically enforced on local messaging for business senders, also known as A2P programs, while imposing new registration requirements and paying additional fees. The throughput limits will vary, but wanted messages in registered campaigns should receive better throughput than the traditional 1 message per second (MPS).
Note: Not registering A2P campaigns with The Campaign Registry doesn't bypass the mobile carriers’ additional per-message fees.
What do I need to know?
Verizon launched their 10DLC program in February 2020 without a pre-registration requirement for A2P senders. Verizon’s A2P program supports additional throughput to Verizon subscribers on all local phone numbers but also includes increased per-message A2P fees. Meanwhile, AT&T and T-Mobile have created plans of their own, which have new and different requirements for local number message senders.
As AT&T and T-Mobile release more information, we'll provide updates on these requirements, including the key differences between the various rules Verizon, AT&T, and T-Mobile all seek to impose.
Verizon has a per message surcharge for Outbound SMS and MMS. The SMS surcharge is $.00255 and the MMS surcharge is $.0052. There are no additional charges or requirements for registering brands or traffic. For more about Verizon 10DLC, please see Verizon 10DLC.
AT&T has imposed a class-based system with different fee amounts depending on the class assigned to a given campaign during the registration process. AT&T has also selected The Campaign Registry (TCR) as a third-party vendor to run their campaign registries. Bandwidth customers can choose to either register their A2P campaigns with TCR directly or work with Bandwidth to register campaign information with TCR.
AT&T has a grace period for registration. Starting on March 1, 2021, all outgoing SMS traffic to AT&T incurs a $.002 surcharge and all outgoing MMS traffic incurs a $.0035 surcharge. This grace period has been extended and we'll provide more information once we have a new date.
Below are the classifications established by TCR and AT&T. For use case definitions and information about the 10DLC registration process, please see Registering Brands and Campaigns for 10DLC.
Note: Special use cases will require additional vetting. The classification process and risk classification are proprietary to TCR.

Terms and definitions
Application-to-person (A2P): As defined by the CTIA, all commercial or business messaging is now considered A2P traffic, whereas person-to-person (P2P) is reserved for mobile end user exchange only, barring exemptions.
10 Digit Long Code (10DLC): The traditional long code phone number which can be utilized for both voice and messaging. Historically, its been used for P2P communication but in the past few years more businesses have begun to utilize these numbers to send messages.
The Campaign Registry (TCR): The newly conceived third-party central hub AT&T and T-Mobile have designated for registering A2P 10DLC messaging campaigns. The Campaign Registry was chosen by AT&T and T-Mobile to register application-to-person (A2P) text messaging campaigns.
Content Provider: The actual brand/entity that is crafting the message content payload to the subscriber.
Direct Connect Aggregator (DCA): A company that has a direct connection to a Mobile Network Operator (MNO) Gateway and transmits messages on behalf of its customers or “content providers”. Bandwidth is an example of a DCA.
Campaign Service Provider (CSP): The primary user of TCR. A CSP works with multiple brands to create and launch SMS messaging campaigns. A customer supporting a large number of different brands may find it easier to work directly with TCR. Customers with fewer brands may want to use Bandwidth as their CSP.
Brand: The company or entity initiating messages to the consumer.
Campaign: A collection of information used to identify use case and CTIA compliance for carrier evaluation. A campaign requires details such as message examples and industry vertical
Class (AT&T Only): There are approximately 15 different classes that may be assigned to a campaign by TCR based on a proprietary system of evaluation established by AT&T. Class assignment is based on elements such as brand identity verification, industry, and use case/campaign type. The class assignment will determine the campaign throughput and per-message surcharge for the campaign. Standard use cases will receive a class assignment immediately upon submission of the campaign (e.g., marketing, customer alerts, account notifications), while special use cases will require external vetting after submission but prior to activation (e.g., political, non-profit).
Reseller: According to TCR, a reseller is a company that supports multiple brands and resells the services of the DCA.

What is The Campaign Registry?
The Campaign Registry (TCR) is a new component to the Long Code messaging ecosystem. It's currently envisioned to be a third-party company chosen by AT&T and T-Mobile for registering A2P 10DLC messaging campaigns. TCR is administered by a third-party company that works with the mobile carriers that have chosen TCR to administer brand registration on their behalf. Verizon has chosen a simpler route that involves a blanket surcharge on top of messages without additional registration.
Why do we need to register 10DLC campaigns?
The industry has been working for many years to find ways to support the use of local numbers to deliver A2P messaging traffic to mobile subscribers at volume. Following the recognition by the CTIA in 2019 that local and toll-free numbers are valid methods for delivering A2P traffic, mobile carriers have been developing their 10DLC solutions.
As described above, AT&T, and T-Mobile have decided to require registration and payment of additional fees as their requirements for increasing throughput caps for campaigns that should be granted a higher messaging class. These carriers are also requiring the use of TCR in order to capture additional information on A2P message senders and what kind of traffic is being sent to their mobile subscribers. TCR enables SMS messaging service providers to register 10DLC campaigns on behalf of the brands they work with.
Can I register via API?
Yes, Bandwidth is developing both a portal and an API for the registration process. TCR already has a portal and an API for customers who are going directly to them.
Will I need to apply for External Vetting?
It depends on your use case and the amount of throughput you need. Brands are considered either:
- Self Declared: Sole proprietors who self declare to their CSP - no verification done
- Unverified: Companies that register and TCR cannot verify their identity
- Verified: Companies that register and TCR can verify their identity
- Vetted Verified: Companies that have registered and their identities have been verified through external vetting
Verified status grants access only to AT&T message classes E/F and T-Mobile brand tier Low. The classes/tiers in the middle require external vetting. If a brand is a Russell 3000 brand, then they will receive access to class A/B and the highest T-Mobile tier.
Bandwidth will be implementing external vetting in the Bandwidth Dashboard shortly, but in the meantime please reach out to your Bandwidth Support Team if you wish to be externally vetted.
Will we need to register campaigns for each brand that a Bandwidth customer supports?
Based on our current understanding, each brand will need to be registered individually. This means similar use cases for different companies can't be lumped together in one registration.
How long will it take a campaign to be approved?
Based on our current understanding, Campaigns for standard use cases should be approved immediately. Specialty use cases will require additional vetting and we're working to confirm an exact timeline with TCR.
What happens if we choose not to register campaigns with TCR?
If you choose not to register but would still like to utilize 10DLC routes, you'll automatically be assigned Class T and the associated attributes (higher carrier per-message surcharge, lowest throughput), but will still be able to send traffic. AT&T has plans to block messages that come from a number without a campaign assigned.
If the traffic is blocked by a carrier, will it also be blocked by its subsidiaries?
Yes, any blocking by a carrier extends to its subsidiaries. For example, if your traffic is blocked by AT&T, it'll also be blocked by Cricket Wireless.
Is there a limit on the amount of phone number associated with a campaign?
AT&T and T-Mobile have determined the upper limit associated with a campaign is 49 TNs unless a Number Pool/Sub ID request has been approved.
What if I don’t agree with the messaging class I was assigned?
If you don't agree with the class that's been assigned to a campaign and you’ve entered all of your information accurately, you may request external vetting from a third-party provider for a fee. Bandwidth doesn't assist or mediate messaging class disputes with TCR. There's a risk of being assigned a lower class than initially given if you choose to dispute.
Who do I contact for troubleshooting issues with TCR?
TCR has a ticketing system where a ticket can be opened by emailing support. However, we believe AT&T is developing a specific escalation path for campaign-related delivery issues (i.e. blocking), which hasn't yet been finalized.
What happens after a campaign is registered?
After successful registration of a campaign, you'll need to assign the Campaign ID to the phone numbers that will be associated with the campaign within the Bandwidth Dashboard. Once selected, these numbers will be activated on the messaging campaign. We'll have more documentation on this process coming soon.
Which Vertical should I choose?
Choose one that aligns with the majority of your customer base. There might not be a direct fit, but choose the closest option.
Do I have to register a campaign and brand for every single customer I have?
A Campaign ID will need to be attached to each phone number to ensure it does not experience any blocking. You will incur higher fees with T-Mobile starting 10/1 if your TNs are not registered/do not have a campaign attached. AT&T has extended their grace period and we'll let you know when they implement a new date.
Should I register with Bandwidth or with TCR directly?
If you support a large number of brands, we encourage you to reach out to TCR directly to explore becoming a Campaign Service Provider (CSP). You'll have the option to begin registering campaigns immediately through them.
If I have two customers with similar use cases, can they be placed on the same brand/campaign?
No, each brand will need to have its own campaign unless they all fall under a larger parent company. Each campaign should be associated with a single company.
Is this only for SMS messages?
No, it's for both MMS and SMS messages.
Where can I ask additional questions?
Please feel free to reach out to your Account Manager if you have any questions not listed above. Not sure who your Account Manager is? Please open a ticket with your Bandwidth Support Team or hit us up at (855) 864-7776!
