A2P (Application-to-Person) Campaigns allow you to register and manage SMS messaging campaigns in the DIDWW User Panel. These campaigns are used to send messages such as alerts, notifications, and customer service responses to users.
Each campaign includes sender ID details, business identity verification, and SMS trunk configuration to ensure compliant and reliable message delivery.
Choose an option below to get started:
Create A2P Campaign
Start a campaign by verifying, setting the sender ID, and choosing an SMS trunk.
Before creating an A2P SMS Campaign, ensure the following requirements are met:
Business Identity and Address – Required for A2P Campaign registration, based on your destination country’s regulations. You can create a business identity in the Identities section.
Outbound SMS Trunk – Required to send SMS messages but optional during campaign creation. For the campaign to function correctly, you’ll need to assign a trunk either during setup or after creation. If you haven’t configured one yet, see the setup guide for your desired trunk type: HTTP OUT Trunk, SMPP ESME Trunk, or SMPP SMSC Trunk.
Note
You can use a DID number with A2P SMS service for campaigns in countries that support Long-Code or Toll-Free Sender IDs. To check availability or purchase an A2P SMS number, visit the Coverage page .
In the create A2P Campaign form, the first step is to complete the campaign details section:
Campaign Name – Provide a descriptive name to help identify your campaign.
Campaign Target Country – Select the country where SMS messages will be delivered.
Sender ID Type – Choose one of the following options:
Long-Code – Used for two-way messaging. Requires a DID number enabled for A2P SMS (e.g., 14155552671).
Toll-Free – Ideal for customer support. Requires a toll-free DID number with A2P SMS capability (e.g., 18001234567).
Alphanumeric – Suitable for branded one-way messaging. Supports letters and digits (e.g., MyBrand).
Review the requirements, verification time, and pricing specific to the selected target country and Sender ID type. This information will help you prepare the necessary details for the next step.
Click Next to proceed to the verification details step.
In the verification details step, provide brand identity information and submit a completed SMS campaign form:
Select your registered Business Identity and corresponding Address.
Note
If you don’t have a business identity or address yet, click Create New. Make sure the provided information matches the requirements displayed on the right side, which are based on the selected target country and Sender ID type.
Download the SMS Campaign Form and complete all required fields.
Upload the completed form by clicking the Select Files button.
In this step, provide the Sender ID information based on the type selected in Step 1: Campaign Details. Depending on the selected option, either choose a DID Number with A2P SMS service enabled (for Long-Code or Toll-Free) or enter an Alphanumeric Sender ID to be used for sending SMS messages.
Select the DID numbers that will be used for this campaign.
Note
Active DID numbers with A2P SMS service will be displayed in the available source numbers section.
If a DID is already assigned to an existing A2P Campaign, it cannot be used for another campaign.
Only DIDs associated with the selected identity will appear as available source numbers.
Move the selected DIDs to the Selected source numbers list using the left and right arrow buttons to include them in the campaign.
In the Remove Sender IDs section, you can remove Sender IDs that have been assigned for A2P messaging. To delete one or more Sender IDs, follow these steps:
This feature is only available for active A2P campaigns using an HTTP OUT Trunk. If the SMS trunk is configured as an SMPP ESME Trunk or SMPP SMSC Trunk, the Send SMS option will not be available.
To send an individual SMS message directly from the A2P Campaigns page, typically for testing purposes, follow the steps below:
