US A2P 10DLC

A2P (Application to Person) 10DLC (10 digit long code) is the standard that United States carriers have put in place to ensure that SMS traffic to US end-users through 10-digit long codes is verified and consensual.

What is A2P?

Application to Person (A2P) messaging is any SMS traffic in which a person is receiving messages from an application rather than another individual. US carriers consider any messages sent from a Notificare number (or any other messaging provider) to be application to person. Traffic sent from an individual person to another person is called Person to Person (P2P) traffic.

What is 10DLC?

10DLC stands for 10-digit long code. A 10DLC phone number contains 10 digits, and is also called a local phone number. When you are buying a US phone number from Notificare, you will most likely see them labeled as Local. Additionally, you can also use Toll-Free numbers and Short Codes to send messages from Notificare to people in the United States.

Why A2P 10DLC was created?

10-digit long codes in the US were originally designed for person to person (P2P) communication. These routes were unregulated, and in recent years have started seeing abuse. Due to the increase in SPAM, many consumers have lost trust in SMS as a form of communication. US A2P 10DLC is the standard that carriers have implemented in the US to regulate this communication pathway. A2P 10DLC improves the end-user experience by making sure that people can opt in and out of messaging and also know who is sending them messages. It also benefits businesses, offering them higher messaging throughput, brand awareness, and accountability.

Who needs to register for US A2P 10DLC?

Anyone sending text messages with a 10DLC number from an application to the US must register for A2P 10DLC. Carriers consider all SMS traffic from Notificare to be sent from an application, so anyone using a 10DLC number with Notificare to send SMS messages to the US will need to register.

Registering for A2P 10DLC results in lower message filtering and higher messaging throughput. Additionally, customers who send messages from a Notificare's 10DLC number but do not register will receive additional carrier fees for sending unregistered traffic.
