10DLC Registration, Step by Step

Registering for 10DLC isn’t hard, but it is unforgiving of sloppiness: most delays come from submissions that don’t match official records or describe campaigns too vaguely for a reviewer to approve. Here’s the process as we run it for customers, with the failure points marked.

Step 1: Brand registration — proving who you are

Your brand is your business identity in the carrier registry. The submission includes your legal business name, EIN, business address, website, and vertical.

Where it goes wrong: the legal name must match your IRS/state records exactly — “Main Street Bakery” fails if the EIN is registered to “MSB Enterprises LLC.” Same for the address. Before submitting, pull your IRS documentation (a CP 575 letter or a recent filing) and copy from it character for character.

Sole proprietors without an EIN can register in a limited category with lower messaging limits — workable for light texting, worth upgrading past if texting becomes a real channel.

Step 2: Campaign registration — declaring what you send

A campaign describes the messages your brand will send: the use case (customer care, appointment reminders, delivery notifications, marketing…), sample messages, and how people opt in and out.

Where it goes wrong:

• Vague descriptions. “General business messages” gets rejected. “Appointment confirmations and reminders for a dental practice; patients opt in at booking” gets approved.
• Sample messages that don’t match the use case. If you register customer-care and your samples read like promotions, expect rejection.
• Missing opt-in/opt-out language. Reviewers want to see how consent is collected and that STOP handling exists. Say it explicitly.
• Mixed use cases crammed into one campaign. Reminders and marketing are different campaigns. Register what you actually do.

Step 3: Carrier vetting

Submissions route through the carrier ecosystem’s vetting process, which assigns your traffic a trust level — affecting how many messages per day you can send and how carriers treat them. Clean, specific, consistent submissions score better. This step is out of your hands, which is exactly why steps 1 and 2 deserve care.

Well-prepared submissions typically clear in days — ours usually in about 72 hours. Sloppy ones bounce back and forth for weeks.

Step 4: Go live — and stay compliant

Once approved, your number sends registered traffic with proper deliverability. Two ongoing obligations:

• Send what you registered. A customer-care campaign that starts blasting promotions invites filtering and re-review.
• Keep consent airtight — the SMS compliance checklist covers opt-in, STOP handling, and message hygiene.

The shortcut

Every Vox Tandem Business SMS setup includes the full registration, done by us: we gather the business details, write the campaign description and samples the way reviewers want them, file everything, and text-enable the number you already own. You get a working, registered texting line without ever learning what a CSP is — though now you know anyway.
