A2P verification, specifically A2P 10DLC (10-Digit Long Code) verification, is a process required for businesses using 10-digit phone numbers to send SMS/MMS messages to the US from an application. It ensures that these messages are sent from legitimate businesses and helps reduce spam. The verification process involves registering the business, its messaging campaigns, and the associated phone numbers with mobile carriers. 

Here’s a breakdown:

What is A2P?

“Application-to-Person” (A2P) refers to the practice of sending text messages from an application (like a business platform) to a user’s mobile phone. 

Why A2P 10DLC?

Carriers like Verizon introduced A2P 10DLC to standardize and secure A2P messaging using regular-looking 10-digit phone numbers. This helps differentiate legitimate businesses from spammers and ensures better message deliverability. 

Who needs to register?

Any business sending SMS/MMS messages via a 10DLC number to the US from an application must register. This includes individuals and hobbyists using platforms like Twilio. 

Registration process:

The process typically involves registering a business profile, a US A2P brand, and specific messaging campaigns. This often includes providing business details, campaign descriptions, and phone number information. 

Benefits of verification:

Verified businesses experience improved message deliverability, increased trust from users, and can potentially avoid carrier filtering or penalties. 

A2P calling:

A2P also extends to voice calls, enabling businesses to send automated voice messages. 

In essence, A2P 10DLC verification is a system for carriers to vet businesses using 10-digit phone numbers for SMS/MMS to ensure legitimate and trustworthy communication. 

Cost:

Monthly Campaign Fees: Recurring monthly charges are applied to each active campaign based on its use case. These fees can range up to $12 per month, in accordance with TCR rules.
