10DLC sole proprietor registration: limits, costs and when to upgrade

If you're a freelancer, a solo contractor or a one-person shop with no EIN, the carriers' standard 10DLC brand path isn't open to you. Standard registration checks your business against a tax ID. Without one, there's nothing to check. The industry's answer is the sole proprietor brand type. It's a cut-down registration tied to a person rather than a company, and it comes with hard limits that catch people off guard a few months in.

This post covers how the sole proprietor path works, where it caps out and what it roughly costs. It also covers the point where a standard brand stops being overkill and becomes the cheaper headache. One thing up front, because it changes your options: Ready registers businesses with an EIN only. We do not offer sole proprietor registration. If you have no EIN and don't want one, you'll register sole proprietor somewhere else. Twilio and some other providers support it. We'll say where that's the right call.

What the sole proprietor brand type actually is

A sole proprietor brand is a 10DLC registration for an individual with no EIN, filed in the US or Canada. You register under your own name rather than a company's. Identity is verified by a one-time code sent to a real mobile number, not by matching a tax ID against government records.

The verification details matter:

• The verification number must be a real mobile number. VoIP and virtual numbers (Google Voice and similar) are commonly refused for the code. If your only business line is VoIP, read why Google Voice and VoIP numbers run into 10DLC trouble.
• Each mobile number can verify only a small number of sole proprietor brands. You can't spin up several of them to get around the caps below.
• No vetting score. Standard brands get a trust score that sets their daily cap. Sole proprietor brands sit in a fixed, low bucket. Paying for brand vetting doesn't change that.

You still need the parts every 10DLC registration needs. That means a clear opt-in path, sample messages that match what you send, and a website or other public presence that shows how people sign up. Our 10DLC website, privacy policy and terms guide covers what reviewers look for. Those requirements are the same at either brand level.

The limits: one number, one campaign, a small daily cap

Most people outgrow the sole proprietor path because of its limits, not its price. Carriers don't publish an official rate card, so treat these as the round figures providers commonly publish:

• One campaign per brand. You pick one use case. Appointment reminders and promos can't run as separate campaigns.
• One phone number per campaign. You can't use local presence across area codes or add a second line for a second service area.
• A low daily cap on T-Mobile, commonly cited at around 1,000 segments a day.
• Very low per-second and per-minute throughput. AT&T in particular throttles sole proprietor traffic hard. A send to a few hundred people goes out over minutes, not seconds.

Remember that caps count segments, not messages. A 160-character plain-text message is one segment. Add one emoji and the limit drops to 70 characters per segment, so the same 140-character text becomes 3 segments. Under a cap of roughly 1,000 segments a day, a friendly emoji in a 140-character text cuts your real capacity from about 1,000 texts to about 333.

Sole proprietor vs a standard brand, side by side

The row people miss is the first one. "Sole proprietor" describes the registration type, not your legal structure. A sole proprietor who has an EIN can register a standard brand. The EIN is what unlocks the standard path, not incorporating.

What each path costs

Sole proprietor fees are set by whichever provider you register through. Usually that means a small one-time brand fee and a low monthly campaign fee. We won't quote another provider's number here, so check the pricing page of the one you're considering. The fixed cost is lower than a standard brand's. That's the main appeal.

On Ready, standard registration has no setup fee. The charge when you submit is the first month, $25. After that the monthly cost is:

• Brand: $10/mo
• Campaign: $20/mo
• Each number: $2/mo

For one brand, one campaign and one number, that's $27/mo in fixed cost before any texts. Our 10DLC cost breakdown itemizes every fee.

A worked example

Here's a solo dog groomer, used as an example. Assume 300 one-segment reminder texts a month on Ready's Standard rate, plus 150 one-segment replies:

• Sent and received segments: 300 + 150 = 450 (replies are billed like a sent text)
• Per-segment rate: 450 × $0.0075 = $3.38
• Carrier fee: 450 × $0.0045
• Fixed registration: $27/mo
• Monthly total: $30.38 plus 450 × $0.0045 in carrier fees

That total is the all-in figure. It excludes the compliance surcharge. TCPA/DNC scrubbing and landline validation each add $0.003 per segment if you switch them on, and both are off by default.

At this volume, most of that total is the fixed $27. That's the honest case for the sole proprietor path. If you will never send more than a few hundred texts a month and you have no EIN, a cheaper sole proprietor registration elsewhere can be a sensible choice. We'd rather say that than sell you a standard brand you don't need.

When a standard brand starts to make sense

The fee gap is small in absolute dollars. The limits are what push people over. Switch to a standard brand when any of these is true:

1. You need a second use case. You send reminders and want to run an occasional promo, so you need two campaigns. The sole proprietor path allows one. Registering the wrong use case to cover both is a common way to get throttled. Our use-case picking guide explains why.
2. You need more than one number, for a second area code, a teammate or a separate line for a second service.
3. A single send would exceed the daily cap. If you have 1,200 opted-in customers and want to reach all of them the same day, the sole proprietor cap won't allow it.
4. You're hiring or adding software. CRMs and booking tools generally expect a standard brand. Moving later means re-registering and going through review again.
5. You'll want vetting later. Brand vetting ($79 Standard / $179 Enhanced, one-time) raises the trust score and can move your daily cap up a tier. It doesn't apply to sole proprietor brands. Our post on whether vetting is worth $79 walks through when that pays off.

If you expect to hit any of these within a year, start on a standard brand. Re-registering means a new review, and most approvals take 2 to 7 days, during which your sending is disrupted.

Getting an EIN is usually the easy part

In the US, a sole proprietor can apply for an EIN directly from the IRS online, at no cost. Once you have it, you can register a standard brand under your business name and EIN. The legal name on the registration has to match the IRS record exactly. Most standard-brand rejections we see come from mismatches, not from content.

What you can do on Ready before you register

If you have an EIN, or you're getting one, here's how Ready handles the period before your registration is approved:

• The first 20 texts are free. They're one-to-one sends; a campaign is paid from its first text. The free texts end as soon as you pay for a registration, so use them before you register.
• You can send up to 500 texts a month before registering, at the normal per-text rate. After that, you have to register.
• If you buy a number before you register, it sends on Ready's shared registration at the same per-text rate while your own registration is in review.
• To send, you add a card and get a number, which is $2 a month with the first month charged when you get it.

Registration itself happens in-app. You submit brand and campaign together, and we handle the carrier side. Once you're registered, STOP and opt-out handling, quiet-hours holds and the per-send consent attestation log all apply automatically. That reduces risk, but compliance is still your responsibility as the sender.

A note on the blue line

A Ready blue line sends as iMessage and needs no 10DLC registration, so it can start as soon as the line is set up. It costs $99/mo per line plus 6 cents a segment, and each line can start up to 50 new conversations a day. It isn't a full workaround. Texts to Android phones go from your regular number at the regular price if you already had a number; if the blue line came with its green number, your account's texts bill at 6 cents a segment once you register, and campaigns send from regular numbers. For a solo business on a tight budget, it usually costs more than a registration. See the blue line guide for details.

The practical takeaway

• No EIN and very low volume: a sole proprietor registration elsewhere is fine. Keep messages plain text so the segment cap goes further, and plan to re-register if you grow.
• No EIN yet, but you expect to grow: get a free EIN from the IRS and register a standard brand from the start. One review beats two.
• You have an EIN: you already qualify for a standard brand. There's no reason to accept the sole proprietor limits.

If you're in the second or third group, you can create an account, send your 20 free one-to-one texts, and submit registration when you're ready. The quickstart guide covers the first steps, and the pricing page shows the per-segment card.
