A2P 10DLC in plain English: what local businesses need to know about texting customers

If you send text messages to customers from a business number, the mobile carriers now want to know who you are and what you are sending. That registration process is called A2P 10DLC. It sounds like jargon, and it is, so here is the plain version.

What the terms mean

• A2P means application-to-person: texts sent by a business through software, rather than one human typing to another.
• 10DLC means 10-digit long code: a normal local phone number, as opposed to a short code or toll-free number.

Put together, A2P 10DLC is the system carriers use to register businesses that text customers from a regular phone number.

Why it exists

Spam and scam texting got bad enough that carriers cracked down. Registration lets them verify that a real, identifiable business is behind the messages. Registered senders get better delivery. Unregistered or sloppy senders get filtered or blocked.

For an honest local business, this is good news. It means your legitimate messages are more likely to actually arrive.

What carriers look for

When you register, carriers check that your messaging is consent-based and transparent. In practice that means:

• Clear opt-in. Customers actively agree to receive texts. You do not buy a list and blast it.
• Identified sender. Messages say who they are from.
• Easy opt-out. Every program supports STOP to unsubscribe and HELP for help.
• A real website that explains your business, with a privacy policy and terms that describe how you handle messaging data.

What this means for you

If you work with us, compliance is built in from the start. We set up proper opt-in, we keep the consent records, and we make sure STOP and HELP work the way carriers expect. We do not cut corners here, because the shortcut that feels faster today is the one that gets your number shut off next month.

If you are texting customers and none of this is in place, that is worth fixing before it becomes a problem. Reply STOP should always work. Consent should always be real. Get that right and texting becomes one of the most reliable channels you have.
