10DLC Registration for Contractors: The Step-by-Step Walkthrough

You signed up for a texting tool, turned on the automation, and your texts vanished. Not bounced — vanished. The dashboard said "sent." Nobody received anything. You didn't do anything wrong except skip one step: registering your business with the carriers before you text. That step is 10DLC, it takes about 20 minutes of your time plus a few days of waiting, and this post walks you through it.

This is part of Pillar A: Capture Every Lead — the compliance companion to the complete missed-call text-back setup guide. Do this before you turn on any texting automation.

What 10DLC actually is (plain English)

10DLC = "10-digit long code" — it's the system US carriers use to register businesses that send texts from regular 10-digit phone numbers. A2P = "application-to-person" — the carriers' term for any text sent by software (your automation) rather than thumbs (your phone). Put together: before your software can text customers from your business number, the carriers want to know who you are and what you'll text about. That's the registration. It's spam prevention, and it's mandatory — unregistered business texts get filtered.

Two things get registered:

• The Brand — your business. Legal name, address, tax ID/EIN, business type (sole proprietor, LLC, etc.), website.
• The Campaign — what you're texting about. The use case (appointment reminders, service updates, marketing), sample messages, and how people opt in.

One brand, one campaign covers all your texting in most small-shop setups — you don't register separately for reminders vs. follow-ups unless your tool tells you to.

Before you start: the 10-minute prep checklist

Have these ready before you open the registration form. Gathering them mid-form is how 20 minutes becomes two hours:

• Legal business name — exactly as it appears on your tax documents, not your DBA. (If you're a sole proprietor, that's your personal legal name.)
• EIN or SSN — the tax ID matching the legal name. Sole proprietors without an EIN use their SSN; the form handles this.
• Business address — the real one, matching your tax documents.
• Business website — with a published privacy policy and terms page. This is the #1 rejection reason we see: carriers increasingly require public privacy and terms pages before approving a brand. If your site doesn't have them, publish them first — most website builders have templates.
• Sample messages — 2–3 examples of texts you'll actually send (your missed-call text-back script, an appointment reminder). Write them the way you'll really send them, opt-out language included.
• How customers opt in — "customers provide their number when booking service" or "website contact form with consent checkbox." Be truthful; this is what the carriers check.

The step-by-step (inside your texting tool)

Every tool (GoHighLevel, CallRail, and the rest) has its own screens, but the flow is the same. Here's the generic version that maps to all of them:

1. Find the compliance section. Look for "10DLC," "A2P," "Compliance," or "Phone Numbers" in your tool's settings. It's usually near where you manage phone numbers.
2. Register the Brand. Enter your legal business name, tax ID, address, business type, and website. Double-check the legal name against your tax return — a mismatch here is rejection reason #2.
3. Register the Campaign. Select your use case. For most contractors: "customer care" or "account notifications" covers appointment reminders, service updates, and follow-ups. If you also send promotions, you may need a "marketing" campaign too — your tool will guide you.
4. Paste your sample messages. Use your real scripts, including "Reply STOP to opt out." Carriers want to see what you'll actually send.
5. Describe opt-in. One or two honest sentences about how people give you their number.
6. Submit and pay. The carrier/campaign fees run ~$15–$20 one-time (varies by tool and carrier). This is not your tool's subscription — it's the carriers' fee, passed through.
7. Wait. Do not text yet. Approval takes 1–7 days. You'll get an email or dashboard notification. Do not turn on automations until you see "approved."
8. Verify with a test. Once approved, text your own cell from the automation. Confirm it arrives, from your business number, with the opt-out language intact.

The three mistakes that get contractors rejected

• No privacy policy / terms on the website. The #1 rejection reason. Fix: publish both pages before registering. They don't need to be fancy — they need to exist and be public.
• Legal name mismatch. Registering as "Mike's Plumbing" when your tax documents say "Michael Smith" gets rejected. Use the legal name; your DBA/brand name goes in the campaign's display fields.
• Sample messages without opt-out language. If your samples don't include "Reply STOP to opt out," the campaign gets flagged. Include it in every sample, even the appointment reminder.

What 10DLC doesn't do (setting expectations)

• It doesn't make you TCPA (federal telemarketing law)-compliant by itself. Registration is the carriers' requirement; the TCPA (the federal law on texting) is separate. You still need consent, opt-out handling, and quiet-hour observance. See the TCPA quiet hours guide.
• It doesn't guarantee delivery. It removes the #1 cause of non-delivery. Content filtering, number reputation, and carrier quirks still apply — see the deliverability troubleshooting guide.
• It's not a one-time-and-forget-forever thing. If you change your business name, add new use cases (like starting marketing texts), or switch tools, you may need to update the registration. Check your tool's docs when things change.

Timeline and cost summary

• Your time: ~20 minutes with the prep checklist done.
• Approval wait: 1–7 days. Budget a full week in your project plan.
• Cost: ~$15–$20 one-time in carrier/campaign fees (varies). Some tools add a small monthly campaign fee — check your tool's pricing page.
• When to do it: the day you create your texting-tool account, before you build a single automation.

Compliance note

This post is general information about carrier registration requirements, not legal advice. 10DLC rules evolve — your texting tool's compliance docs are the current source of truth, and they update as carriers change requirements.
