What is 10DLC - A2P?

10DLC, not to be confused with describing a 10 digit phone number, is a

system that American cellular service carriers have established to deliver A2P

(Application to Person/Business to person) text messages.

10DLC operates using the same pool of phone numbers Entrance customers

are already accustomed to

10DLC exists to ensure deliverability of business texting by separating the

usage type from person to person and unregistered traffic altogether.

As you may have noticed, carriers have recently begun increased message

filtering. This is due to the new 10DLC system.

At this time, all traffic and campaigns on Entrance are sent via unregistered 10

digit phone numbers, a product and practice that has been available and

standard for decades. Due to regulations and significant upticks

in foreign malicious activity via SMS scams, all American senders will be

required to register themselves and their campaigns/brands with the 10DLC


Once registered, you will experience uninterrupted service.
