What is 10DLC (10-Digit Long Code)?

Skip to table of contents

A 10-digit long code (10DLC) is a 10-digit phone number used for business messaging in the US. It requires a special registration process and must comply with US messaging guidelines.

Also called A2P 10DLC, this type of number was introduced as a substitute for businesses using P2P numbers and unsanctioned shared short codes. 10DLCs are easier and quicker to set up than short codes, have lower setup and monthly costs, and support a growing number of business messaging use cases.
