What is 10DLC and do dog groomers need it?

Yes — if you send appointment reminders or confirmations by text from a US business number, those messages fall under 10DLC, the carrier registration system for application-to-person SMS. Without it, business texts get filtered or blocked. GroomBoard handles 10DLC registration and compliant sending on your behalf, so your reminders actually reach clients.

10DLC stands for "10-digit long code" — the standard local phone number format — and it refers to the registration US carriers require for businesses sending automated or bulk SMS from those numbers. Since mid-2023, unregistered business texting is subject to heavy carrier filtering, which means reminders can silently fail to deliver.

For a dog groomer, this matters because appointment reminders are exactly the kind of application-to-person messaging 10DLC governs. If you were texting clients from a raw, unregistered number or tool, you would risk undelivered reminders and carrier-violation errors.

GroomBoard manages the 10DLC brand and campaign registration and sends reminders through a compliant, registered number, including STOP/START opt-out handling. You do not have to file paperwork with carriers yourself — the deliverability and compliance are handled as part of the service. See how reminders work below.

Do I have to register for 10DLC myself?
Not with GroomBoard — registration and compliant sending are handled for you. If you text clients from your own raw carrier number outside a registered platform, you would need to register yourself.
What happens without 10DLC registration?
US carriers filter or block unregistered business SMS, so reminders may not be delivered and you can see carrier-violation errors. Registration is what keeps reminders reliably landing.
Does 10DLC handle opt-outs?
Compliant 10DLC sending includes STOP/START opt-out handling. GroomBoard processes opt-outs automatically to keep your texting compliant.
