10DLC Compliance Explained: What Dealerships Actually Need (and What They Don’t)

Douglas Karr January 29, 2026

A fast response is the difference between a closed deal and a lost lead in today’s car buyer’s journey. Text messaging (SMS) has become the gold standard for reaching customers, but behind the scenes, the rules of the road for texting have changed.

If you’ve heard the term 10DLC and felt a headache coming on, you aren’t alone. Here is everything you need to know about why it matters and how Overfuel makes it simpler than any other platform.

What is 10DLC?

10DLC stands for 10-Digit Long Code. In plain English, it’s a system required by major cell phone carriers (like Verizon and AT&T) to verify that the businesses sending texts are legitimate.

Think of it like a digital license plate for your dealership’s phone number. Without it, your messages are more likely to be flagged as spam, blocked by carriers, or never delivered.

Why It Matters to Your Business

  • Deliverability: Proper registration ensures your appointment reminders and “car is ready” texts actually hit the customer’s pocket.
  • Brand Trust: Customers feel safer engaging with a dealership that follows transparent privacy and consent rules.
  • Legal Safety: Staying compliant protects you from heavy carrier fines and keeps your communication lines open.

Fact Over Fiction: What You Actually Need for 10DLC Compliance

Many platforms leave the complex compliance work to the dealer, often following outdated or overly cautious advice. It’s common to see large CRM companies propose lengthy disclosure blocks comprising five or six paragraphs and three or four separate checkboxes. This approach is not only wholly unnecessary for carrier approval but also detrimental to your conversion rates. Nothing scares off a high-intent lead faster than a wall of “legalese” before they can even ask a question.
