If you are sending SMS or MMS messages to U.S. numbers from local U.S. or Canadian numbers using Aircall, you must complete the A2P 10DLC registration process. Even if your business is based outside the US, you will still need to register A2P 10DLC details to send outbound SMS to US numbers. This ensures compliance with U.S. carrier requirements and prevents your messages from being blocked or filtered.
What is A2P 10DLC
A2P 10DLC (Application-to-Person 10 Digit Long Code) is a regulatory framework that requires companies using long code numbers to send SMS to US consumers to complete a registration process. This helps ensure transparency, accountability, and compliance with US messaging regulations.
In addition, toll-free numbers in the US and Canada must also be registered separately before they can be used to send SMS messages. You can read more about it in the article Messaging Compliance for Toll-Free US/Canada Numbers.
Submit your A2P 10DLC registration
Important: A2P 10DLC registration is required for sending SMS messages to U.S. recipients from local US and Canadian numbers. Outbound SMS on unregistered numbers will be blocked and fail delivery.
Steps:
- In the Aircall Dashboard > Numbers section > click on A2P Registration (US) button
- If you do this for the first time, click on the “Create campaign” button or “View registration process” link.
- Fill in the registration form with the required business and campaign information.
- Submit the form to begin the review process.
- Once submitted, an automated support ticket will be created. You will receive updates there as your registration is processed. If we need more information, our Customer Support team will request it within the ticket.

Messaging use cases
This is the second step of the A2P 10DLC registration process - Campaign Registration.
By completing these fields, you register the type of messages you plan to send, the purpose behind them, and the content they will include.
Your campaign description must align with all other information you provide (including details in the Call to Action and Sample Messages sections). It’s essential to be as detailed as possible, as the reviewers do not have any prior context about your organization or why you are sending SMS/MMS messages to mobile phones.
Use case
| Do's | Don'ts | Comments |
|---|---|---|
| Select the use case matching your SMS activity. | Choose a use case unrelated to your SMS content | For low volume/conversational use, choose “Mixed” or “Low volume” |
Note: If Mixed Use case, Sub-use case (1 to 3): Select the sub-use cases that match your SMS activity. The most common sub-use cases are Customer Care, Account Notification, Delivery Notification, and Marketing.
Check the A2P 10DLC Registration statuses to find the list of use cases and their definition.
Use case description
| Do's | Don'ts | Comments |
|---|---|---|
| Provide a detailed description (min. 40 characters). Example: “We use text and SMS for general customer care interactions.” | Be vague (e.g., "text my clients") | Describe precisely how your business will use text messaging. • It must include your message frequency disclosure (for example: "Messaging frequency varies"). • Avoid vague phrases like "This is to text my clients for commercial purposes," as such descriptions will cause your campaign to be rejected by TCR. |
Sample messages (1-3)
You will need to provide at least three sample messages. The sample messages should be a good example of what you might send outbound and must match your use case. Provide realistic sample messages (min. 20 characters each). You must provide sample messages that:
- Match the registered use case(s).
- Identify the brand.
- Include at least one example with opt-out language.
- Include embedded links or phone numbers if these attributes are marked "Yes".
An example of a good sample message would be something like:
“Hi there, this is Aircall. We have received your support inquiry and are reviewing the information. We’ll get back to you as soon as we can. Reply STOP to opt out."
Tip: If your campaign has multiple use cases, provide one sample message for each use case.
Embedded links
- Select YES if you’ll be sending any links or URLs, select NO if you won’t be sending any links or URLs.
- Must include a link in at least one sample message.
Embedded Number
Select YES if you will include any phone numbers in your outbound messages, select NO if you will not be sending any phone numbers in your outbound messages
Age-gated content
- Select yes if your messages will include age-gated content.
- Age-gated content in business text messaging refers to messages that are restricted to recipients who must meet a minimum age requirement, such as for alcohol and tobacco.
Subscriber opt-in
Subscriber opt-in is mandatory. You must collect consent before sending messages. The opt-in disclaimer must include:
- Brand name
- Types of messages (customer support, informational, promotional, etc.)
- Message frequency disclosure
- “Message and data rates may apply” disclosure
- HELP information
- STOP information
- Link to privacy policy and terms
Example opt-in disclaimer:
I have read and agree to the privacy policy and terms. By submitting this form and signing up for texts, you consent to receive customer support and informational text messages from [Brand Name] at the number provided, including messages sent by autodialer. Consent is not a condition of purchase. Msg & data rates may apply. Msg frequency varies. Unsubscribe at any time by replying STOP. Reply HELP for help. Privacy Policy [link] & Terms [link].
Example opt-in confirmation message:
Thank you for opting in to receive recurring messages from [Company Name]. Msg frequency varies. Msg & data rates may apply. Reply HELP for help. Reply STOP to cancel.
Subscriber help
This message is sent when a recipient responds with a “HELP” message. Help keywords must trigger a help message that includes:
- Brand name
- Contact details (email address, phone number, or website link)
- Opt out instructions
Example help message:
Thank you for reaching out to [Brand Name]. Please call us at [phone number] or email us at [email address] for support. Reply STOP to opt-out.
Subscriber opt-out
You must provide opt-out keywords and a confirmation message. The opt-out message must include:
- Brand name
- Confirmation that the consumer will no longer receive messages
- min. 20 characters
Example opt-out message:
You have successfully opted out of messages from [Brand Name]. You will receive no further messages.
Message flow
You will need to explain how consumers opt-in to receive messages. Providing vague or inaccurate call-to-action information will result in a rejection and delay your registration process.
The call-to-action must:
- Minimum 40 characters required.
- Clearly describe how consent is obtained.
- Include all available opt-in methods (web forms, verbal scripts, keywords, IVR, etc.).
- Provide supporting materials (scripts, forms, screenshots, or links).
All opt-in methods must disclose:
- Brand name
- Types of messages
- Message frequency disclosure
- “Message and data rates may apply” disclosure
- HELP information
- STOP information
- Link to the Privacy Policy
- Link to the Terms & Conditions
Important: If a messaging campaign includes marketing alongside other use cases, the opt-in for marketing messages must be collected separately from other types of messaging.
For example, if a business plans to send both customer support and marketing text messages, customers must provide distinct consent for each, such as two separate checkboxes: one specifically for marketing and another for non-marketing communications.
