What is 10DLC?

10DLC, short for 10-Digit Long Code, is a 10-digit phone number format that needs to be registered and approved by a mobile network operator to support high volume SMS Messaging.

10DLC (10-Digit Long Code) is the next step in A2P messaging, created to ensure efficiency and compliance in automated SMS messaging. Adopting 10DLC means aligning with a framework designed to optimize (bulk) A2P messaging with enhanced reach, higher delivery rates, and cost savings.

Want to send out A2P SMS, RCS, or MMS messages as a business in the United States?
Then adopting 10DLC is mandatory.

10DLC registration is required by wireless carriers to ensure that SMS text messaging services are used responsibly and in compliance with all relevant laws and regulations. Why? The main goal of 10DLC is to combat spam and fraud, which are common issues in A2P messaging services. In fact, content that is reviewed as spam can be fined up to $100 per message.

How to Register for 10DLC?

First, a business must register with Campaign Registry, a centralized hub for A2P 10DLC messaging campaigns. Brands and Campaign Service Providers (CSPs) must be verified before sending messages via 10DLC.

Mobile carriers are working with Campaign Registry to enable businesses to verify and register their SMS campaigns. The Campaign Registry uses an algorithm to review specific company criteria to assign you a “Trust Score.” This Trust Score determines your messaging throughput or the speed at which your messages are sent. The higher your Trust Score, the higher your messaging throughput.

A service provider, like CM.com, connects directly with Campaign Registry, so you don’t have to go through a third party to get started. Campaign Registry charges a one-time $4 fee for registration, and a monthly $10 registration fee per campaign.
