An explanation of messaging and common issues with carriers.
Whistle provides an Application to Person (A2P) messaging platform, which differs greatly from day-to-day Peer to Peer (P2P) messaging. “A2P 10DLC” refers to a system in the United States that allows businesses to send A2P type messages via standard 10-digit long code (10DLC) phone numbers. Carriers in the US consider all Whistle traffic to be A2P.
These are instances of carriers (most commonly AT&T and T‑Mobile) occasionally blocking messages from being delivered in the A2P setting. Certain carriers have very strict Spam filters, and this results in messages getting caught in these filters temporarily. If you’ve ever seen a ‘Carrier Violation’, then you’ve had your messages declined to send to your recipient.
The good news is that most of the major carriers are working on rolling out a new A2P 10DLC ‘highway’, which will allow you to register your business and prevent filtering moving forward. The anticipated launch date, starting with AT&T, is expected to be soon. Once launched, Whistle will find out all of the requirements in order to participate and include your organization as well.
What Do I Need to Do?
Nothing right now — hang tight! We are still awaiting finalized requirements and procedures from our partners.
Will There Be an Added Cost?
Most likely, yes. While this hasn’t been finalized by the carriers, and is subject to change, there will most likely be a fee associated with registering your company.
