A2P 10DLC (or sometimes just A2P) is the shorthand telecom providers are using to mean being a "verified" sender of business-related text messages.
Mobile carriers are going to start filtering out text messages from non-verified senders or labeling them as "spam likely," decreasing the chances of those messages reaching the intended recipient. Companies who follow best practices for business texting will be excited to be able to send verified texts.
What does A2P 10DLC actually stand for?
A2P 10DLC stands for Application-to-Person messaging using a 10-Digit Long Code phone number. Translation to layperson terms: it means you’re using software technology to send text messages using a local phone number.
The alternative methods to A2P 10DLC messaging are:
P2P - Person-to-person messaging that happens between two mobile carrier plans.
Short code - A five or six digit number that brands use to push or receive messages. Often they are multi-tenant, with a keyword assigned to each brand. (Example.: “Text REDCROSS to 90999 to donate $10.”)
Toll-free - using an 800 number
OTT - Over-the-Top media service which is direct messaging using the internet (Example: WhatsApp)
A2P 10DLC is a great way for businesses to reach customers because it allows for efficient communications at scale. You use a local, recognizable area code which builds trust as you slide into consumers’ most guarded, urgent inbox.
Mobile Carriers Will Soon Require A2P 10DLC Users To Register
As business-to-consumer texting has increased in popularity, there has been an increase in bad actors who abuse the channel. Because of mounting complaints, the three largest mobile carriers in America (Verizon, AT&T, and T-Mobile) have decided to implement a verification method to improve the customer experience, effective Summer 2021.
Short code and toll-free messaging already require verification, and A2P 10DLC verification is the logical next step to build greater trust between businesses and consumers and provide consumers greater control over their message inboxes.
For all companies hoping to use A2P 10DLC, there will be a registration process that will result in a company/brand verification. The initial company registration (Your business profile) is a one-time event in the Trust Center. After your business brand is verified, you can register to become a verified texter. Each text campaign/use case will need to be identified and approved before they are launched.
