AT&T is expected to throttle messages for unregistered traffic and T-Mobile is expected to block unregistered traffic. To continue to send A2P 10DLC sms and mms messages, you must register immediately to avoid any 10DLC-related service impacts and fines come October 1.

What do I need to know?

10DLC is the industry's way of self-regulating messaging by finding out who's sending messages, why they're sending them, and confirming that the end-user has opted in to receive the messages. In order to self-regulate, brands and campaigns have to be registered with The Campaign Registry (TCR), either directly or through Ytel.

You may be wondering about short code and toll-free (TFN) A2P traffic and how it will be impacted by these impending rate limits. It won't be. Short code has an established briefing process and Toll-free A2P traffic is exempt from this requirement of 10DLC, but TFN A2P numbers have a similar whitelisting process for optimal delivery. At this time A2P/10DLC is specific to long code phone numbers only.

What do I need to do?

Ytel is here to help. Pull up a virtual chair and let's talk! If you haven’t already registered your 10DLC numbers, and been approved, it is important to start now. The process can take a few weeks to complete, so please begin now. Our Account Management and Operations teams can assist with the process of 10DLC registration or TFN whitelisting to support your use case.

  • Campaign Service Activation Fees ($50)

  • Campaign Service Migration Fees ($50)

  • NNID Registration and Setup ($2000)

  • Noncompliance Fees (excluding Grey Route Noncompliance Fee)

    • Text Enablement - if Company or a Message Sender text-enables a 10-digit NANP telephone number and sends Messages prior to verification of Message Sender ownership. ($10,000)

    • 10DLC Messaging Program Evasion - for each unique instance of a violation: Snowshoe sending, dynamic routing, spam filter evasion, unapproved campaign service ($1,000)

For clarity, T-Mobile will not be charging the Special Business Review Request fees or the Grey Route Noncompliance Fee at this time. T-Mobile will provide a 30-day notice before beginning to charge these fees.
