Texting registration (A2P)

Business texting in the US requires registration with the carriers. It is called A2P 10DLC, it is not optional, and unregistered messages get filtered or blocked without telling you.

Why this exists

Carriers got tired of spam sent from ordinary ten-digit numbers. So they built a registry: businesses declare who they are and what they will send, and registered traffic gets delivered. Unregistered traffic gets throttled, filtered, or silently dropped.

Silently is the problem. You will not get an error. Your messages will simply not arrive, and you will spend a week blaming the product.

What you register

Two things, in order:

Your brand. Who your business legally is. Legal name, EIN, address, website, a contact person. This must match what the IRS has, character for character. A mismatch here is the single most common rejection.

Your campaign. What you will actually send. For LeadBind that is customer care and appointment messaging: confirmations, reminders, and replies to people who contacted you.

What you need before you start

Have these in front of you:

• Legal business name, exactly as registered
• EIN
• Business address
• A website that describes what you do
• A contact name, email, and phone
• Sample messages you will send
• The opt-in language from your own lead form

That last one matters more than people expect. Carriers want to see how people agreed to hear from you. If your form has no consent language, add it before you apply. See Consent and opt-outs.

How long it takes

Brand registration is usually quick. Campaign approval commonly takes several business days and can take longer if anything is rejected.

Apply before you need it. Do not launch a campaign on Monday and discover on Tuesday that texting has not been approved.

Common rejections and the fix

Rejection	Fix
Business name does not match	Use the exact legal name on your EIN paperwork, not your DBA
No opt-in evidence	Add clear consent language to your lead form and reference it
Website does not explain the business	Carriers actually look. A parked page fails
Sample messages look like marketing	Describe what you really send: confirmations and replies
Missing opt-out language	Include how people stop, in the samples

Until you are registered

Calling still works. Voice is not part of A2P, so your AI receptionist answers and dials normally.

Texting is what waits. That means:

• No automated confirmations or reminders by text
• No text follow-up sequences
• No two-way inbox

Everything else runs. You are not blocked from using LeadBind, you are blocked from one channel.

Tip: Appointment confirmations can go out by email instead, with a calendar invite attached, while your texting registration is pending. That covers most of what you lose.

After approval

Turn texting on and check the first few sends actually land. Then:

• Reminders and confirmations to cut no-shows
• Follow-up sequences for leads who did not answer

Everything in Consent and opt-outs applies to all of it. Registration lets you send; it does not decide who you may send to.
