If You Text Customers, This Registration Is Non-Negotiable
If you send business texts from a regular 10-digit number and you haven’t done A2P 10DLC registration, your messages are getting filtered — and you might not even know it.
Here’s the reality of texting in the US: carriers decided they’d had enough of spam, so now every business sending from a standard local number has to register who they are and what they’ll send. It’s called A2P 10DLC, and skipping it doesn’t mean a warning — it means your texts quietly stop landing. Let’s make it make sense.
Two pieces: a Brand and a Campaign
Registration is built on two things. Your Brand is your verified business identity — it proves a real, legitimate business is behind the messages. Your Campaign describes what you’ll actually send: appointment reminders, account alerts, marketing. Carriers want both approved before they’ll fully trust texts from your number, because together they answer “who are you” and “what are you going to send my customers.”
Skipping A2P doesn’t get you a warning. It gets your texts quietly filtered into nowhere.
Pick the right Brand type the first time
Most businesses register one of two ways. If you have an EIN — an LLC, corporation, any formally registered entity — you’re a Standard Brand. If you’re not a separate legal entity, you register as a Sole Proprietor Brand. Choosing the wrong path is a common cause of delays and rejections, so match it to how your business is actually set up before you submit.
What carriers are really checking
When they review your Campaign, carriers are matching your stated purpose against your opt-in language and sample messages. Your consent flow needs to be real and clear, your HELP and STOP handling needs to work, and your content can’t fall into the forbidden categories. Get those aligned and approval is straightforward; fudge them and you get rejected. One bit of relief: if you are rejected, there’s no extra fee to fix and resubmit.
A quick legal note: this is general information, not legal advice — the messaging rules that apply to your business are yours to confirm with counsel.
The takeaway
If you text leads or customers from a local number, treat registration as step zero, not a someday task. Figure out whether you’re a Standard or Sole Proprietor Brand, get your opt-in language honest and documented, and submit your Brand and Campaign. You submit through the platform, but the carriers make the call — so accuracy up front is what gets you approved and keeps your texts landing.
