A2P 10DLC Compliance Checker

Nine quick yes/no questions about your texting setup. Get a readiness score and a clear fix-it list for every gap. No signup needed.

1. Are you texting from a regular 10-digit local number (10DLC), not a toll-free or short code?
2. Have you registered your Brand with The Campaign Registry (usually done through your provider, e.g. Twilio)?
3. Have you registered a Campaign (use-case) under that Brand?
4. Is your business registered with an EIN (not a sole proprietorship)?
5. Do you collect and keep documented opt-in before texting a customer?
6. Does your opt-in language name your business, state message frequency, mention 'msg & data rates may apply', and explain STOP/HELP?
7. Do you honor STOP instantly (no further texts) and respond to HELP?
8. Do you avoid prohibited content (cannabis, firearms, gambling, adult content, debt collection, and other SHAFT/high-risk categories)?
9. Do you monitor your trust score / throughput limits with your provider?

How it works

  • Answer questions about your Brand and Campaign registration, opt-in practices, and content rules
  • The checker scores your answers
  • Every "no" or "not sure" gets a plain-English explanation of why it matters and what to do

Why it matters

Carriers actively filter and block unregistered texts. That means your appointment reminders, review requests, and follow-up texts can silently fail to arrive. A few minutes of registration up front stops that from happening.

Frequently asked questions

What is A2P 10DLC?

It stands for Application-to-Person messaging on 10-digit long code numbers. US carriers require it for businesses texting from regular local numbers. It means registering a Brand and a Campaign with The Campaign Registry.

What happens if I text without registering?

Carriers now heavily filter or block unregistered texts. Your messages can silently fail to deliver, and providers like Twilio increasingly require registration before you can send at all.

Can a sole proprietorship register for 10DLC?

Yes. But sole-proprietor registration comes with lower throughput limits and more restricted use cases than a business registered with an EIN. If you text a lot, registering as a proper business pays off.

What opt-in language do I actually need?

Your consent flow needs to: name your business, state roughly how often you'll text, include "message and data rates may apply," and explain how to reply STOP or HELP. Missing any of these is a common reason campaigns get rejected.

How long does registration take?

Brand registration is often near-instant to a few business days. Campaign approval varies — plan for anywhere from same-day to a couple of weeks, especially for higher-risk categories.

Is this checker legal advice?

No — it's educational information to help you self-assess common gaps. 10DLC requirements evolve regularly; always confirm current rules with your messaging provider (e.g. Twilio) before registering.
