A2P 10DLC Registration

How to register for A2P 10DLC for United Stated SMS messaging.

Updated over a week ago

IMPORTANT: We are experiencing delays while vetting A2P 10DLC brands and campaigns. Our third party is reviewing campaigns manually, and due to the high volume of requests, a queue has built up. Campaign reviews are expected to take longer. Call Loop is working with the provider to help expedite this process. New details will be shared in Twilio's (our provider) incident report as soon they become available.

Are you a Call Loop customer looking to send important business messages to your customers? Well, we've got some great news for you!

Our A2P 10DLC Verification process helps ensure your messages get delivered and seen by your customers. As long as you follow the rules and regulations (including Call Loop's Messaging policy), you can expect to experience fewer message filters on 10DLC traffic to major US and Canadian networks.

And to make things even better, we've created a comprehensive overview to help guide you through the 10DLC registration process.

To start your A2P 10DLC registration, you first must complete the Business Profile. to get here go to Settings > Company > Compliance.

Step 1: Choose Your Company Type

In order to get approved for 10DLC, you MUST have United States EIN number to verify your business. There is no way around this.

If you do not have an EIN, then the only option for you would be to get a toll-free phone number.

Step 2: Use Case

Use Case

Select the use case that best fits the description of how you will use Call Loop.

Use Case Description

Please describe the use case and how you plan on using SMS.

✅ Approved Example

⛔ Rejected Example

Sending promotions to opted-in customers about deals and discounts.

Alerting opted-in contacts about open roles and job opportunities.

Step 3: Opt-in Method

How will contacts give consent to receiving text messages from your company?




Using Call Loop's Keywords feature, people will opt-in by sending a keyword to your Call Loop number. (e.g. Text LOOP to 555-555-5555)

Web Widget

Using a tool like Intercom to capture a phone number and connect with a contact.,


Using Call Loop's webforms, people will fill out that form and get added to your Call Loop list.

Incoming SMS

People text your phone number and opt-in that way.

Incoming Call

People text your phone number and opt-in that way.


Integrating Call Loop with your CRM, people will get messages from your system.

For informational campaigns that use a text-to-join, QR code, or other mechanism that is excessively prohibitive to illustrate via a hosted image file, describing the opt-in workflow in detail is acceptable.

In as much detail, provide how a consumer/subscriber opts into this submission. The opt-in submitted should be what the mobile user sees when providing their phone number:

  • Online/app (URL, screenshot/webpage)

  • See in store (Keyword, signage)

  • Hears (IVR script/verbiage)

Please note this should be the description only, any links should be included.

✅ Approved Example

⛔ Rejected Example

Keyword Coffee. The keyword is found on a sign at the register of John’s Coffee Shop where customers can see the keyword and text in to the local number. Once the customer texts the keyword, they are provided a double opt in where they are asked to Reply Y to confirm they would like to receive promotional SMS

Keyword/Text to join. Online. Point of Sale.

The more detail about the opt in process, the better. The information provided for review should be clear to the Verification Ops team what specifically the customer does to opt in/sign up to receive SMS from the end-user business.

The examples of opt in are just a starting point. There needs to be details explaining exactly what the customer does.




  • What is the keyword?

  • Where does the customer find the keyword?

  • What happens after the end-user/mobile handset texts the keyword to the local number?


  • What is the direct URL to the opt in/sign up page?

  • Screenshots of the opt-in/sign up page are acceptable.

  • This should be the SMS opt in/sign up, not emails.

Point of Sale

  • What is the process?

  • Where does the customer give the consent?

  • Provide a screenshot/picture/url and language the customer is agreeing.

Opt-in Images

Consent is one of the cornerstones of A2P messaging.

Opt-In workflow description should briefly describe how the handset gives consent to the business to receive messaging. Opt-in images can contain screenshots of the opt-in clearly displayed on the end-user’s website, an image of where opt-in is collected, or an image of relevant opt-in practice.

Provide images of the opt-in process and what a subscriber is agreeing to. This should be where the customer’s phone number was entered by the customer agreeing to receive the SMS.




  • Provide the link to the direct opt in page or a screenshot of the website opt-in page.

  • Only the phone number opt in page should be included; An opt-in for an email address is not acceptable for SMS TFV opt-in.

  • This must be a full, valid, working URL that is publicly accessible in order for the team reviewing to access the required information.

Text to Join

  • What is the keyword?

  • Where does the consumer/subscriber find the keyword?

  • Screenshots/pictures/urls are best.

Point of Sale

  • Provide a screenshot/picture/url of the opt-in from the POS, language the customer is subscribing to.

IMPORTANT: Only including “online”, “text to join”, “point of sale”, “web” is not enough for the opt in requirement for 10DLC approval.

Seeing directly how the customer opts in/signs up for SMS helps the Verification team understand exactly what the customer sees and signs up for.

✅ Approved Example

⛔ Rejected Example

Direct URL to the opt in sign up page or hosted image of the opt in URL or Screenshot of the SMS opt in page.

URLs that don’t direct to the exact sign up, URLs that are behind a login/password screen, URLs that don’t resolve. The 10DLC approval team needs the direct link to the opt-in/sign up.

Note: Seeing directly how the customer opts in/signs up for SMS helps the Verification team understand exactly what the customer sees and signs up for.

Note: Please test all included URLs if possible to ensure they work properly, check for typos, etc. Verification may fail due to a misspelled or inaccessible URL.

Step 4: Samples Messages

The carriers want to see sample messages of what you plan on sending using this use case. Please provide two samples of the messages you'd likely send.
