In an effort to protect the SMS communication channel and prevent spam, robo-texts, and malicious content, the U.S. mobile carriers are requiring all Application-to-Person (A2P) text campaigns to be registered in the Campaign Registry to verified and vetted senders. Unregistered SMS traffic will be severely limited by throughput, deliverability, and cost.


10 Digit Long Code (10DLC) is the new standard for A2P text messaging campaigns utilizing a traditional 10 digit phone number. Although similar to the existing long code, 10DLC is a reliable messaging channel with throughput levels suitable for SMS campaigns and is sanctioned by the mobile operators for A2P messaging. 

The Campaign Registry (TCR™)

The Campaign Registry is the central hub for registering A2P 10DLC messaging campaigns.

TCR works with North American mobile operators and companies that are in the messaging business to register A2P text messaging campaigns. The registry supports a sanctioned A2P 10 Digit Long Code (10DLC) text messaging campaign ecosystem and provides visibility into the messaging source and content, allowing mobile carriers to provide a more reliable and simple messaging service for Campaign Service Providers (CSPs) and Brands.

Colligso, a CSP

Colligso is a registered Campaign Service Provider (CSP) of The Campaign Registry. Colligso provides a platform to Brands to create and launch their messaging campaigns. Colligso is a multi-tenant hyperlocal customer engagement software as a service (SaaS).


Businesses can register their brand and campaigns with the Campaign Registry using Colligso. Colligso provisions a 10DLC phone number to each registered brand and associates it with each registered campaign.

When should you register brand and campaigns?

  1. If you are seeking reliable messaging channel with high delivery rates, high throughput (messages/second) and content that is sanctioned by the mobile operators for A2P messaging.
  2. To use highly effective picture messaging (MMS) with content sanctioned by the mobile operators for A2P messaging.
  3. If you are in Canada, even to use Toll-Free number for text messaging requires business verification. That process is manual and takes weeks and months. 

TCR requires businesses to register their brand using their business tax identification information. You can do this right from your Colligso account.


Please refer to TCR Fees for each brand and campaign registration as of 2023. All fees are passed to the business by Colligso and are non-refundable.
