If you're sending business text messages in the US, you'll need A2P 10DLC registration. It's a carrier requirement — not optional. dialnote walks you through the whole process right from your Settings panel, so you won't need to deal with Twilio directly.

The registration has two parts: first you register your brand (your business identity), then you register one or more campaigns (what you're actually sending). Let's break it down.

Brand Registration#

Your brand registration tells carriers who you are. Head to Settings → Compliance and click Start Registration to begin the 3-step wizard.

Step 1 — Business Info:

• Pick your business type: Sole Proprietor (individual or single-member LLC) or Standard (LLC, Corporation, Partnership)
• Enter your legal business name — this must match your IRS records exactly
• Add your EIN (format: XX-XXXXXXX) if you picked Standard. Sole proprietors can skip this
• Provide a contact email — you'll get a verification email during submission

Step 2 — Compliance Links:

• Your website URL — must be publicly accessible, not behind a login
• Your privacy policy URL — carriers check that it states you don't sell personal data to third parties

Step 3 — Review & Submit:

• Double-check everything and hit Submit. Your brand moves to Pending status while Twilio and the carriers review it.

Brand statuses you'll see:

Campaign Registration#

Once your brand is approved, you can register campaigns. Each campaign describes a specific type of messaging you'll do. Click Add Campaign on the Compliance dashboard to start the 4-step wizard.

Step 1 — Use Case: Pick the category that best fits your messaging. Options include:

• Customer Care — support messages, appointment reminders, follow-ups
• Account Notification — billing alerts, service updates
• Marketing — promotional messages (requires explicit opt-in consent)
• Two-Factor Auth — verification codes and login alerts
• Security Alert — password resets, suspicious activity warnings
• Mixed — multiple use cases combined

Then write a campaign description (at least 40 characters) explaining what you'll send and why.

Step 2 — Sample Messages: Add 2–5 sample messages that represent what you'll actually send. A few rules:

• At least one message must include your business name
• All messages must include opt-out instructions (like "Reply STOP to unsubscribe")
• Each message needs to be 20–1,024 characters
• You can use placeholders like {name}, {date}, {company}, and {order_id}

Step 3 — Consent Configuration:

• Describe how users opt in to your messages (at least 40 characters) — for example, "Checkbox on website contact form"
• Set your opt-out instructions (defaults to "Reply STOP at any time")
• Set your help instructions (defaults to "Reply HELP for support")

Step 4 — Review & Submit: Check everything over. Once submitted, your campaign goes through carrier vetting.

Throughput Limits#

After your campaign is approved, carriers assign throughput limits based on your business type and trust score:

These limits are set by the carrier network and can increase over time as your trust score improves.

Key Requirements#

A few things to keep in mind before you start:

• One brand per organization — you can only have one brand registration per dialnote workspace
• Brand must be approved first — you can't submit campaigns until your brand passes review
• STOP and HELP keywords — dialnote automatically handles these. When someone replies STOP, they're opted out. HELP sends your configured support message
• Keep your privacy policy current — carriers can suspend registrations if your privacy policy doesn't meet their standards
• EIN accuracy matters — for Standard registrations, your EIN must match IRS records exactly, or the registration will be rejected
