Decoding 10DLC Use Cases: Maximize Approval Rates

When navigating The Campaign Registry (TCR) portal—or submitting via your SMS provider like Twilio, Vonage, or Sinch—you will encounter a drop-down menu asking you to define your "Campaign Use Case." To the uninitiated, this seems like a simple administrative categorization, a mere label for filing purposes. In reality, this single drop-down selection is one of the most critical decisions in the entire A2P 10DLC registration framework. The Use Case you select dictates the level of manual scrutiny your campaign will endure, the base cost of your monthly campaign registration, the per-message surcharges you will pay to carriers, and most importantly, the maximum messaging throughput (TPS/TPD) your campaign will be allowed to achieve.

Fundamentally, carriers classify use cases to understand the exact nature of the traffic traversing their networks. This allows them to allocate bandwidth, predict spam risks, and protect consumers. There are over a dozen standard use cases, ranging from "2FA" (Two-Factor Authentication) and "Account Notifications" to "Customer Care" and "Marketing." From a carrier's perspective, not all traffic is created equal. A "Customer Care" campaign—where consumers are texting in for support and an agent is replying—is considered low-risk, solicited, and highly valuable. Conversely, a "Marketing" campaign blasting out promotional coupons is considered high-risk and is heavily policed for CTIA violations and S.H.A.F.T. (Sex, Hate, Alcohol, Firearms, Tobacco) content.

The Danger of the "Mixed" Use Case

When faced with the list of options, many businesses and agencies panic. They think, "Well, we send appointment reminders, but sometimes we also send a coupon code, and occasionally our support team replies to questions. We do a little bit of everything!" Consequently, they select the "Mixed" or "Low Volume Mixed" use case. This is frequently a massive strategic error.

Carriers inherently dislike ambiguity. When you select "Mixed," you are essentially telling the carrier firewall, "I could be sending anything at any time." Because this represents a higher spam risk, carriers often penalize Mixed campaigns. For example, T-Mobile generally assigns lower daily throughput limits to Mixed campaigns compared to specific use cases within the same Trust Score tier. Furthermore, the monthly campaign registration fees are often higher. From a vetting standpoint, Direct Connect Aggregators (DCAs) scrutinize Mixed campaign submissions much more harshly because they have to verify that your opt-in flow covers every possible type of message you might send. If your primary objective is marketing, register a Marketing campaign. If it is 2FA, register 2FA. Specificity breeds deliverability.

Navigating "Special" Use Cases

Beyond standard selections, TCR designates certain categories as "Special" Use Cases. These include Political Campaigns, 501(c)(3) Charities, Emergency Services, and K-12 Education. These use cases are highly regulated but come with significant benefits, such as vastly increased throughput limits and heavily discounted (or waived) per-message carrier surcharges.

However, you cannot simply claim to be a charity or a political entity to get cheaper messaging. Special use cases require secondary, external validation. For example, Political campaigns must obtain a "Campaign Verify" token—a cryptographic proof that they are a registered political entity with the FEC or state election boards. Charities must prove their 501(c)(3) status. If you select a Special Use Case but fail to provide the exact, required documentation, your campaign will be rejected, and your brand may be flagged for attempting to circumvent standard routing protocols.

The Rule of Absolute Congruency

The most common reason for a Use Case rejection is a lack of congruency between the drop-down selection and the rest of the application. TCR reviewers are trained to look for logical alignment.

If you select the "Account Notifications" use case, but the sample messages you provide to the reviewer say, "Flash Sale! Use code SAVE20 for 20% off all inventory today!" your campaign will be instantly rejected for a "Use Case Mismatch." If you select "Customer Care," but your opt-in website explicitly states, "Sign up for our marketing newsletter," you will be rejected.

To ensure a first-time approval, your application must tell a single, coherent story. The Use Case you select must directly mirror the content of your Sample Messages. Those sample messages must logically flow from the Call to Action (CTA) and opt-in disclosures on your website. Finally, your Privacy Policy must support the collection of data for that specific purpose. By treating your Use Case selection not as a minor admin task, but as the architectural foundation of your entire 10DLC compliance strategy, you will avoid rejections, lower your costs, and maximize your SMS deliverability.
