10DLC (10-Digit Long Code) messaging is the most efficient way for businesses in the U.S. to connect with customers using trusted local numbers for transactional and promotional messages.

This guide walks you through everything needed to guarantee campaign approvals on the first go — from Brand registration to website compliance — regardless of your industry. Let’s dive in!

Before creating a campaign, you must first register your Brand (i.e., your business entity) with The Campaign Registry (TCR). This is quick and straightforward.

• Legal business name

• EIN or Tax ID (from W9, W2, or IRS)

• Business address

• Estimated number of employees

• Website URL

👉 Brand Verification Guide

Once your brand is approved, the next step is creating a 10DLC messaging campaign.

• Campaign Type: Choose one that matches your message use case. (e.g., 2FA, Marketing, Customer Care)

  🔗 Use Case Guide

• Campaign Description: Describe what kind of messages you’ll send.

  E.g.: “Outreach to clients about new insurance programs, answering policy questions, and renewal alerts.”

• Call to Action (CTA): Clearly explain how the user opts in.

  Example: “User submits info via our website demo form and checks a box agreeing to receive texts.”

• Sample Messages: Add real examples, including STOP/HELP instructions.

  “Welcome to ABC Insurance. Reply STOP to opt out. Msg & data rates may apply.”

• Multi-Media Attachments: If you send MMS (images, PDFs, videos), register them as samples.

• Campaign Attributes:

  • Opt-in Keywords: START, SUBSCRIBE

  • Opt-out Keywords: STOP, UNSUBSCRIBE

  • Help Keywords: HELP

  • Embedded links? Phone numbers? Age-gated? Mark them as needed.

If your CTA includes a website form, carriers will review your website for compliance.

• Business identity

• Explicit opt-in language

• Link to Privacy Policy

• Statement about STOP/HELP and data rates

Examples:

“By submitting this form, you agree to receive SMS from Signal House. Reply STOP to opt out. Msg & data rates may apply. See our Privacy Policy.”

This is the most critical part of review — T-Mobile and CTIA are strict about it.

1. How users opt-in/opt-out of messaging

2. That you do not share data with third parties for marketing or promotional purposes

   If you must share data for legal reasons:“SMS opt-in data is not shared or sold to third parties for marketing or promotional purposes. SMS opt-in data is excluded from any data shared.”

💡 Copy this exactly to avoid rejections.

Before your campaign can move forward for approval, we require a quick KYC (Know Your Customer) call, a brief 15-minute conversation where our team gets to know your business better and understands the kind of traffic you'll be sending out. This helps us verify your account and move your campaign along smoothly.

As soon as you create your account on the Signal House portal, you'll see a banner prompting you to book your KYC call to get verified, just click through and pick a time that works for you.

Internal rejections are completely free (compared to a $15 fee for DCA rejections). If your campaign doesn't pass the first time, we'll give you clear rejection reasons and help you resubmit, our job is to make sure you get approved the first time. 💪

Heads up: lead generation and affiliate marketing are banned use cases on Signal House. Campaigns tied to these use cases won't be approved, so it's worth double-checking your use case before submitting.
