-------------------------

If you're using an application platform (e.g. SignalWire) to send customers messages from a local phone number,
you need to register with the Campaign Registry regardless of your use case.
In this guide, we will walk you through what the Campaign Registry is and why is it important to register.

<Info>
  The Campaign Registry only applies to 10DLC/local numbers sending messages to local US phone numbers. **If you are sending messaging exclusively outside of the US or only from toll-free/shortcode numbers, this guide is not for you!**

  These pages containing an overview of TCR rules and regulations and FAQs illustrate SignalWire's most current understanding of carrier plans. Many of these details are still being finalized and could be subject to change, however SignalWire will continue to update this information as TCR evolves.
</Info>

## What is the Campaign Registry?

The usage of extended codes for messaging campaigns has increased due to their simplicity and ability to meet the needs of Application-to-Person (A2P) messaging between businesses and customers. As text message volume has increased, some businesses have used the same technology for sending spam text messages. This proliferation of spam is bad for customers, businesses, and the mobile industry overall.

With the above in mind, the Mobile Network Operators (MNOs) have partnered up with a company called Kaleyra to create The Campaign Registry. This platform is a single source of information about 10DLC messaging campaigns throughout the U.S., enabling the MNOs to serve as a record of who sent any given 10DLC message and what they claim to be sending, which can be checked and validated against actual messaging behavior.

The Campaign Registry is about creating a centralized, trusted access point to key information enabling messaging service providers such as SignalWire, to exchange transparency (directly with the MNO’s) in who they are and what they are doing for more predictable and reliable service delivery to end-users.

MNO's can now have visibility into the “who” and “what” of each messaging campaign which allows them to provide a better quality of service for 10DLC messaging, while service providers like SignalWire can have confidence knowing that they are using an officially sanctioned messaging channel. Businesses can finally benefit from a better quality of service as well as better predictability of success for your messaging campaigns.

## How is SignalWire involved?

SignalWire is proud to be at the forefront of these changes by working with all of our partners within this new communications ecosystem since its inception. Our priority is ensuring that your business is thriving and there is no disruption. We are fully committed to providing you with these updates as they are received and assisting you with adapting whatever changes are needed.

We will help you register and get your numbers and messaging verified with the registry, and navigate you through all the changes.

## Who needs to register?

If you're using an application platform to send messages to the customers, **regardless of the conversational nature of the use case**, then it is considered A2P (Application-to-Person) and you **need** to register. In other words, if you are using SignalWire to send messages to customers, you need to register your brand, campaigns, and phone numbers.

<Warning>
  Registering with the Campaign Registry is mandatory for **all 10DLC traffic to US numbers**.
</Warning>

Brands registering with The Campaign Registry will have their legal company name, legal company address, and EIN/Tax ID checked against multiple databases, resulting in either a **Verified** or **Unverified** status. Any brand marked Unverified can update their details and resubmit to The Campaign Registry. Each submission incurs a `$4` charge.

Given the way that each brand is viewed, every brand that is registered must have a **unique EIN**. This means that no two brands may share the same EIN or you will risk damaging your companies trust score.

## Terms to know

There are four categories of players involved in this ecosystem -

* **MNO** - These are the Mobile Network Operators aka wireless carriers (Verizon, AT\&T, T-Mobile, Sprint, etc.). These are the companies that deliver your messages to the End Users.
* **DCA** (Direct Connect Aggregators) - These companies directly connect to the MNO’s gateways and transmit messages on behalf of its customers, such as SignalWire.
* **CSP** - This Is SignalWire - A Campaign Service Provider provides messaging services to its customers. A CSP works with its customers (aka Brands) to create and launch new and successful messaging campaigns. SignalWire is a fully registered CSP!
* **Brands** - This is the company or entity that will be sending the messages to its End Users.

## Registration best practices

<Steps>
  ### Be transparent and honest

  You do not want to be in a situation where you are flagged for an error in your brand information or other information requested. More information on this is below.

  ### Provide clarity and detail

  We advise you to be clear and detailed, especially for special use cases.
  Your use case is what you are using that campaign for.
  This lets the MNOs know what type of messaging to expect.
  Here’s a list of the use cases that you can select from.
  When reviewing a campaign, carriers will look at the campaign description and see if it matches the content of the messages being sent.

  | Standard Use Case           | Description                                                                                                                                                                                          |

  ### Provide message templates

  To verify that your use case is what you say it is, the registry also asks for messages or message templates that you would be sending. Even if you do not expect to have standard messages, try coming up with a few of your most common scenarios, especially if you are going to use the campaign for some common use cases, to help the registry judge your validity. Opt-out language is a must!
</Steps>

<Info>
  When you create a phone number assignment for a brand new campaign, SignalWire has to send information up to our carriers in order to get it connected on their end. **For a brand new campaign, this process can take up to 24 hours in normal circumstances.** You may see failed or pending for the number assignment order during this time. Rest assured that as soon as it's completed on the carrier end, you will see it reflected in your portal!

## Frequently asked questions

<AccordionGroup>
  <Accordion title="Does the TCR requirement apply only to SignalWire?">
    No! This is an industry-wide program and all messaging service providers will need to abide by and be part of this new ecosystem to help ensure messaging compliance among the industry as a whole. SignalWire strictly adheres to all carrier guidelines and regulations when it comes to registrations. Any platform like SignalWire would be required to go through the 10DLC registration process that occurs through The Campaign Registry.
  </Accordion>

  <Accordion title="Once the Campaign Registry registration is complete, am I clear to send?">
    No, the campaign must be vetted by our DCA and connections must be accepted upstream before you're able to send messages, which  DCA vetting times can vary typically around 24-48hrs. Once your Campaign is fully vetted and we (SignalWire) inform you that your Campaign is connected, you will need to assign any phone numbers and ensure their assignment status is "Complete" before sending (number assignments may take up to 24hrs to complete). See our next question on DCA Election. Phone numbers must also be assigned to a Campaign ID. Once you are informed by SignalWire via Email that your Campaign is connected and your phone number assignment status is "Complete", you will be able to start sending.
  </Accordion>

  <Accordion title="What is a DCA election?">
    Direct Connect Aggregator (DCAs) are the companies that provide direct connectivity to mobile carrier gateways for the purpose of delivering SMS messaging. In short, a DCA is that organization confirming that the campaign in question is registered with the Campaign Registry. *DCA election occurs when our upstream DCA completes their campaign vetting process and the campaign connection request has been accepted.*
  </Accordion>

  <Accordion title="What is Campaign Verify?">
    [Campaign Verify](https://www.campaignverify.org/) is a third-party SMS campaign verification platform that 527 organizations must go through in order to gain access to the Political use case.
  </Accordion>

  <Accordion title="T-Mobile sets a daily SMS limit for each brand. When does that count reset each day?">
    T-Mobile resets their counting towards your daily SMS limit every day at Midnight, US Pacific Time.
  </Accordion>

  <Accordion title="What information is required to register?">
    There are essentially two components to become registered:

    1. **Brands** - First, we need to register your business as a Brand on The Campaign Registry. Once registered, a Brand is given a unique Brand ID that is associated with ALL its campaigns and numbers, and messages. To become a Brand, the registry requires you to provide details about your business such as official company name, website, Tax ID / EIN, company contact name, direct number, and email.
    2. **Campaigns** - We will then need to register each of your unique campaigns. Once registered, each campaign will also be given a unique ID which will be registered directly with the MNOs (carriers). Information required will be your campaign's use cases, opt-in/out process, help process, and message samples.
  </Accordion>

  <Accordion title="How long does the registration process take?">
    Approximately 3-5 business days (can take shorter or longer depending on the information submitted).
  </Accordion>

  <Accordion title="Can I use multiple long code numbers in one campaign?">
    Yes, as long as you have a valid use case for doing so. The maximum is 49 numbers currently; anything more than that will require additional registration for Number Pooling. If this applies to you, open a Support Ticket and we will discuss this in more detail with you!
  </Accordion>

  <Accordion title="What if I don't register?">
    If you do not register, you will not be able to send messages from a local US number to another local US number using our platform. Registration is required!
  </Accordion>

  <Accordion title="Why can't I send or receive messages on my newly purchased 10DLC number?">
    As of December 2025, newly purchased US 10DLC numbers do not have messaging capabilities enabled by default. Messaging is automatically enabled when you assign the number to an approved TCR campaign.

    If you need **inbound-only messaging** (receiving messages without sending), you can contact [Support](https://support.signalwire.com/portal) to request enablement without a full campaign registration.

    For testing purposes, your first purchased number is automatically enabled for Platform Free Trial messaging when paired with a verified mobile number.
  </Accordion>

  <Accordion title="What if my traffic is P2P (person to person)?">
    SignalWire provides non-consumer messaging routes for businesses, and even if your traffic is "conversational" in nature, it will still need to be registered.
  </Accordion>

  <Accordion title="Does this apply to toll-free numbers?">
    No! Toll-Free numbers have to go through a totally unrelated verification process.

  <Accordion title="What factors will affect my maximum approved throughput?">
    For Brands that are not part of the Russell 2000 list, your default throughput to T-Mobile is 2000 segments per day. External vetting may result in a higher daily throughput. For the other carriers, throughput is determined by use case!
  </Accordion>

  <Accordion title="What if my throughput is not high enough for my needs?">
    If the throughput for your campaign does not fit your needs, there are 3rd party vetting partners of the registry that allow for additional vetting.
    There are added costs associated with that process and added vetting does not guarantee a better outcome.
  </Accordion>

  <Accordion title="What exactly is a campaign?">
    The simplest way to describe a campaign is a unique use case. For example, if you send marketing messages and also send alert messages, that would represent two different use cases. However, mixed use case campaigns are possible for lower traffic cases. See the [use case table](/docs/platform/messaging/campaign-registry#registration-best-practices) for more details.
  </Accordion>

  <Accordion title="How many campaigns will I need?">
    You need one campaign per use case as defined above. Some businesses will require only one use case/campaign (ie....I only send marketing messages). Other businesses may require many use cases/campaigns (ie....I send marketing and alert messages). There are mixed use cases available for businesses that aren't worried about throughput.
  </Accordion>

  <Accordion title="Can I go directly to the Campaign Registry to register?">
    SignalWire has been at the forefront and has become a registered CSP (Campaign Service Provider) so that we can handle registration on your behalf and make it easier for you. That said, if you still prefer to directly go to the Campaign Registry on your own, please reach out to your sales representative for further details and read our guide on
    [Campaign Service Providers](/docs/platform/messaging/campaign-registry/campaign-service-providers).
  </Accordion>

  <Accordion title="How will I know when I am fully registered and ready to go?">
    Our dedicated Campaign Registration Specialists will be working closely with you from the time you have submitted your request until all steps have been completed.
  </Accordion>

  <Accordion title="Once I am registered, can I send anything I want?">
    No! As mentioned, registration is not a green-light ticket to send anything. In fact, the system is set up so that the MNOs have a way of knowing who and what they are sending allowing for proper enforcement. ALL messaging industry guidelines set forth by the CTIA as well as the MNOs must still be followed to ensure successful message delivery. Those details can be found in our
    [best practices guide](/docs/platform/messaging/sms-best-practices).
  </Accordion>

  <Accordion title="What if I change my messaging content?">
    If the content change is related to the same use case you used during the initial Campaign registration process, no changes will likely need to be made. However, if the new content you are looking to send is not related to the original use case, you would likely need to have that information changed within the registry. If you are not sure, please contact one of our Campaign Registration Specialists.
  </Accordion>

  <Accordion title="What if I want to add an additional number to my current campaign?">
    As mentioned above, as long as there is a valid reason you are needing to add an additional number to a current and active campaign, you are able to do so from the Messaging Campaigns Space on your Dashboard.
  </Accordion>

  <Accordion title="What if I want to add a new campaign?">
    You can start the process by accessing the "Messaging Campaigns" tab within your SignalWire Space or by using our [API](/docs/apis/relay-rest/campaign-registry/create-campaign)!
  </Accordion>

  <Accordion title="Will there be daily messaging limits?">
    T-Mobile has a daily cap on the number of message segments you can send to their network, per brand.
  </Accordion>

  <Accordion title="What if I send messages to SignalWire at a higher throughput rate than I am approved for?">
    SignalWire has built a queuing system on our end that will queue up your messages and send them out in accordance with the approved throughput limits. This ensures all your messages will be delivered even if you send them at a higher than approved rate.
  </Accordion>

  <Accordion title="My company provides messaging services to multiple companies, how do I go about getting them registered?">
    The Campaign Registry provides for a Reseller persona. In addition, you have the option to register as your own CSP (Campaign Service Provider) directly with the registry. Please reach out to your sales representatives with a support ticket to discuss these options in further detail.
  </Accordion>

  <Accordion title="Do these changes affect my shortcodes?">
    No! SignalWire currently offers dedicated short code services. Dedicated short code services are not affected by TCR.
  </Accordion>

  <Accordion title="What about other mobile networks?">
    Some MNOs are not currently participating in the Campaign Registry. This whole ecosystem is still very new as well as a large industry change. The Campaign Registry is continuing to work with all the MNO's and we expect them all to join in the near future. We will provide those updates accordingly. However, SignalWire will still be requiring registration for all 10DLC A2P traffic (regardless of MNO), in order to prevent future hiccups that will occur when other MNOs do eventually join the Campaign Registry.
  </Accordion>

  <Accordion title="Do these changes apply everywhere or just in the US?">
    If you are sending messaging exclusively outside of the US, you do not need to register with TCR.
  </Accordion>

  <Accordion title="What if I am already registered on the Campaign Registry with another provider, will I need to re-register again when migrating to SignalWire?">
    Yes! Each messaging provider is its own CSP (Campaign Service Provider) and therefore registered uniquely with The Campaign Registry. If you are migrating from another provider, you will need to go through this process again.
  </Accordion>

  <Accordion title="If I am migrating from another provider, will my messages be blocked before I am registered with SignalWire?">
    No! Your registration with your current provider will remain in place until you request campaign deactivation. Until your campaign with SignalWire is fully registered, we suggest using your current provider for messaging in the meantime.
  </Accordion>

  <Accordion title="What if I switch to another provider in the future, will I need to re-register?">
    Yes! As mentioned, each messaging provider is its own unique CSP (Campaign Service Provider). Therefore, you would need to go through the same process with the new provider when switching over.
  </Accordion>

  <Accordion title="Can I have numbers with multiple providers at the same time?">
    Yes! However, you would need to register with each provider accordingly for each set of numbers.
  </Accordion>
</AccordionGroup>
