Tuesday morning you sent an appointment reminder. Nobody showed. You called at noon and the customer said she never got a text from you, not that one and not the two before it. Your screen says all three went out. So now you are guessing. Is something wrong with your phone? Did she block you? How many other people did this happen to this week? The answer is almost never your phone, and it is a different problem from the one that puts a spam label on your calls. It also decides whether your reminder texts ever land. By the end you will know what 10DLC registration is, whether you have to do it, what it costs, how long it takes, and the opt-out rules that decide if you get approved.
Your texts are being dropped because the carriers do not know who is sending them. 10DLC registration is how you tell them. Carriers filter unregistered business texts, so skipping it means your messages quietly go nowhere.
- 10DLC just means a normal 10 digit phone number used by a business instead of a person.
- You register two things: your business, called a brand, and each reason you text, called a campaign.
- You do this through your texting platform. You do not sign up with the registry yourself.
- It is cheap. The registry charges a few dollars to file your business and about ten dollars a month per campaign.
Why this holds: The Campaign Registry, the hub the carriers built for this, says in its April 2026 guide that any business texting customers or employees on a 10 digit number "is required to register." That covers shops sending one message at a time, not only mass texting.
Key takeaways
- Registration is not a marketing rule. One appointment reminder counts.
- You never sign up with the registry. Your texting platform files for you.
- Money is not the obstacle. Filing costs a few dollars, a campaign about ten a month.
- Time is. Review runs one to four weeks, so start before your busy season.
- Registering as a sole proprietor caps you hard. Get an EIN first.
What is 10DLC, in plain English
10DLC stands for 10 digit long code, which is the ordinary ten digit phone number you already have. The "A2P" next to it stands for application to person, the industry's way of saying software sent the message instead of a person typing it.
For years businesses texted from regular numbers and nobody checked. Then the junk got bad enough that the phone companies built a shared system. Now a business number sending automated texts is filed in one place with a name attached, so a carrier can see who is sending and why before it delivers.
That place is The Campaign Registry, and everyone in the chain calls it TCR. Here is the part that trips people up: you are not TCR's customer. If you are a business that wants to text customers, its guide says "registration directly with TCR is not the correct path for you," and points you at your messaging provider instead.
So if you have been hunting for a login, stop looking and ask your texting platform. The next question is whether you even have to.
Do I need to register if I only text a few customers a day?
Yes, and this is the single biggest thing owners get wrong.
Most articles frame 10DLC as a marketing rule, so a shop that never sends a blast assumes it is exempt. TCR's own words say otherwise. Registration covers "businesses that do mass texting or marketing, as well as businesses that send individual messages, even if it is not for marketing purposes."
Read that again. A one line text saying your tech is twenty minutes out is business messaging. So is a payment reminder, a review request, and a "we are here" note from the driveway. If software sent it, it counts.
There is one narrow gap. If a customer texts you first and a person on your end types a reply, that is a conversation, and the industry guide from CTIA, the wireless trade association, treats it that way. The moment anything automatic goes out you are back in scope, and most shops crossed that line the day they turned on reminders.
That same guide splits your texts three ways, and the split decides what consent you need. A conversation the customer started needs nothing extra. A reminder is informational, meaning they gave you the number and asked to hear from you. Anything with a promotion in it, even a coupon code on a reminder, needs them to agree in writing first.
What does 10DLC registration cost?
Less than almost everyone expects. TCR publishes its price list in its July 2026 provider guide, so these are the registry's own numbers rather than a vendor's guess.
| What you pay for | Registry price |
|---|---|
| Filing your business, with an EIN | $4.50, one time |
| Filing your business, sole proprietor | $4.00, one time |
| Most campaigns, including marketing and mixed use | $10.00 a month |
| Low volume campaign | $1.50 a month |
| Sole proprietor campaign | $2.00 a month |
| Standard vetting, to raise your sending limits | $41.50 per vet |
| Enhanced vetting | $101.50 per vet |
Two things before you budget. Every campaign carries a three month minimum billed monthly, then renews month to month. And your texting platform may add a fee on top, so ask what the all in number is.
The money is not what stops people. The calendar is.
How long does it take, and why campaigns get rejected
Filing your business is quick. Getting a campaign approved is not. TCR says review "can range from 1-4 weeks," so plan around that if you want texts working before a promotion you already booked ads for.
The other thing worth knowing is who says no. TCR "does not review, approve, or reject campaigns." Providers and carriers further down the chain do, so arguing with the registry gets you nowhere.
Here is the trap that bites shops which switched vendors. Carriers can suspend at the level of your EIN, not just your listing. Every listing under that tax ID then stops qualifying, including ones filed through a different platform. Two texting tools on one EIN means one bad campaign takes down both.
5 things to fix before you register
Most rejections come down to paperwork that does not match, not to anything wrong with the business. Get these right and you usually clear on the first try.
- Match your legal name to your tax paperwork exactly. Not the name on the truck, the name on your IRS letter. A missing "LLC" fails an identity check.
- Get an EIN if you do not have one. Sole proprietor filing exists for people without one, and it costs you dearly in sending limits.
- Have a real website with your business name and phone on it. Reviewers open it, and a parked domain reads as thin.
- Write down how people agree to your texts. A screenshot of the checkbox on your booking form, the wording beside it, and where that form lives. This is the most common gap.
- Put your opt-out and help wording in the messages. Reviewers check it against the samples you submit.
Number two costs real money, so it gets its own section.
How many texts can I send once I am approved?
Approval is not one size. Each carrier puts you in a lane, and the lane depends on how well you were verified.
The numbers in that July 2026 guide are stark. File as a sole proprietor and AT&T allows 15 texts a minute while T-Mobile caps you at 1,000 a day. File with an EIN and pass standard vetting, and the same guide puts a well scored business at 2,400 to 4,500 a minute on AT&T, with a T-Mobile daily cap of 40,000 and up.
For a two truck shop 1,000 a day sounds like plenty, right up to the morning your office fires reminders, review requests and an estimate follow up in the same hour. That $41.50 vet is the cheapest thing on this list and it moves you the most.
The opt-out rules in effect right now
This is where campaigns get rejected, and where a shop can land in real trouble later.
Federal rule 47 CFR 64.1200(a)(10) has been in force since April 11, 2025. Three parts of it matter to you.
First, "stop" is not the only word that counts. The rule lists seven that always work: stop, quit, end, revoke, opt out, cancel, and unsubscribe. Other words count too, if a reasonable person would read them as "quit texting me."
Second, you cannot make one method the only method. The rule says a sender "may not designate an exclusive means" to opt out, so "reply STOP, this is the only way to unsubscribe" is not allowed.
Third, you have a clock. Every opt-out has to be honored "within a reasonable time not to exceed ten business days."
One piece is on hold, and plenty of write ups get it the wrong way round. The part of the rule that would make an opt-out from one kind of message stop all your other unrelated messages is waived. The Federal Communications Commission extended that waiver in an order released January 6, 2026, and it now runs to January 31, 2027. Waived means not yet in force, not dropped. Build your list now so one "stop" is easy to apply everywhere in your automations, and January will not cost you a rebuild.
One more useful detail. A single confirmation text after someone opts out is allowed, so long as it only confirms and carries no marketing. Send it inside five minutes and it is presumed fine.
That covers the rules. What is left is getting your own filing through.
FAQ
Does 10DLC registration also fix my calls being labeled as spam?
No. Call labeling is graded by separate firms on how you dial, while text delivery turns on whether you registered. You can pass one and fail the other on the same number, on the same day.
What happens to texts I send while my campaign is still under review?
Assume they do not arrive. Carriers filter unregistered business traffic and the failure is quiet, so your screen still shows sent. Call or email anything that has to land.
Do I need a separate campaign for reminders and for promotions?
Usually yes, because the use case is what you are registering. Reminders and a discount blast are different reasons to text with different consent rules, so they are normally filed separately.
Can I use my main business line for texting?
Often yes, since a 10DLC number carries voice on the same line. Check with your provider first, because a landline has to be enabled for texting before it can be filed.
I registered two years ago. Do I need to do anything?
Look at it. Requirements have tightened since 2023, and older filings with thin descriptions or vague consent wording get flagged on later review. Check what was submitted still describes what you send today.
