Application-to-person 10-digit long code numbers (A2P 10DLC) are dedicated routes for US business messaging. They are local numbers with an area code like 415, 212, or 310 for a local messaging experience.
After completing 10DLC registration, brands can send SMS messages with increased throughput and deliverability—capturing the benefits of short codes without the cost or long time to market.
