Description: The purpose of this article is to provide an overview of the process for linking 3rd party messaging applications with the 2600Hz platform.


To enable SMS/MMS services on 2600Hz, there are several steps to follow:

  1. Register your brand and campaign for texting.
  2. Assign phone numbers to the campaign.
  3. Enable SMS/MMS for those numbers.
  4. Finish setup by connecting 2600Hz with your texting application.

Let’s explore each of these steps in detail.

Step 1. Register your brand and campaign with your carrier

To use SMS/MMS, you must have a registered 10DLC campaign. These campaigns have extensive requirements and can take time.

10DLC (10-Digit Long Code) Campaigns are carrier-approved messaging registrations that describe how a business uses US 10-digit phone numbers to send A2P (application-to-person) SMS or MMS messages. Each campaign defines the sending brand, messaging purpose, sample content, and opt-in/opt-out practices. Carrier approval is required to prevent spam, ensure compliance, and maintain reliable message delivery.

If you already have an account with The Campaign Registry, you can register your texting campaigns through that platform. For more information, please consult Brand Registry resources.

Otherwise, contact your carrier directly (including Trunking.io, Ooma Carrier Services provider), as most carriers provide tools for registering brands and campaigns as a pre-requisite for texting. You can check a carrier for each number using Free Carrier Lookup portal.

Due to the surge in campaign submissions, vetting may take up to 12-15 business days.

You can refer to this article on registration best practices to help prepare all required documentation in line with campaign registration requirements.

Step 2. Assign phone numbers to the campaign

Once the campaign is approved, the phone numbers you want to use for texting must be added to the campaign. To do this, contact your carrier or use the tools they provide for this task. This includes Trunking.io, Ooma Carrier Services provider.
