Why your practice needs its own A2P registration to text patients
If you are planning to text patients, there is a piece of plumbing nobody mentions in the sales call. It is called A2P 10DLC, and it decides whether your messages arrive at all.
Here is the short version. US carriers no longer let businesses send bulk texts from ordinary phone numbers without saying who they are first. You register a brand, you register a campaign describing what you will send and how people opted in, and the carriers approve or reject it. Unregistered traffic gets filtered, throttled, or silently dropped.
The part that catches practices out
The registration is tied to a brand, and the brand has to match the website where people opted in.
That sounds obvious until you look at how most vendors operate. A marketing agency signs you up, texts go out through the agency’s registered brand, and the opt-in lives on a form branded for your practice. Carriers notice. Twilio returns error 30927 when the campaign and the opt-in do not line up, and the fix is not a support ticket. It is a new registration.
We ran into exactly this ourselves. RecallCrew texts need RecallCrew’s own brand and campaign, registered against our own opt-in page, even though the parent company already had an approved registration for its other work. Editing the approved campaign would not have fixed it. You cannot borrow someone else’s trust.
What this means for your practice
Your practice needs its own registration to text your patients. Not your agency’s. Not ours. Yours.
That is not a sales position, it is how the system works. The consent your patients give is consent to hear from your practice, on your intake forms, about their appointments. A vendor’s registration does not cover it, and a vendor who tells you otherwise is either mistaken or hoping you do not ask.
Practically, you will need:
- Your practice’s exact legal name as it appears on IRS records
- Your EIN
- Your website
- A description of how patients opt in, matching what your forms actually say
- Sample messages that look like the ones you will really send
How long it takes, and why that matters
Approval is not instant. It is usually days, sometimes longer if something in the submission does not match. That delay sits inside whatever onboarding timeline you have been promised.
This is worth asking about directly. If someone tells you they will have your recall campaign texting patients within two weeks, ask when your A2P registration gets filed and what happens if it is still pending. An honest answer is that the first wave leads with phone calls and mail, which need no registration, while the texting approval works its way through.
That is what we do, and it is one of the reasons the postcard is not a gimmick. Mail does not wait on a carrier.
A quick checklist before you sign anything
- Who is the registered brand for texts sent to my patients? If the answer is not your practice, stop and ask why.
- Who files the registration, and when?
- What goes out during the gap before approval?
- If I leave, do the phone numbers and the registration come with me?
That last one matters more than it sounds. We think you should own both, and we say so on the homepage.
Not legal advice
This is a practical summary of how carrier registration works, written by someone who has been through it, not a lawyer. The rules around business texting also involve consent requirements under the TCPA, which is a separate topic and a real one. Talk to counsel before you start texting patients at scale.
If you want the recall work handled without you becoming an expert in any of this, that is the job. And if you just want to know what your lapsed list is worth first, the report takes two minutes.
