This page is for OpenPhone users who now see the Quo name and need to finish carrier registration, or whose registration was rejected. Quo says every customer who texts US numbers from its local numbers must register, including for personal use. Unregistered numbers cannot text US numbers.

10DLC Site is not affiliated with or endorsed by Quo or OpenPhone. Provider names are used only to describe where information goes. This page describes the flow as documented at the time of writing (Updated September 2026). Screens change, so follow what you see in your account.

Is OpenPhone the same as Quo?

Yes. OpenPhone's help center and blog now use the name Quo and call it "formerly OpenPhone." The registration steps below come from the Quo Resource Center.

Which registration does Quo use, and who submits it?

Quo uses A2P 10DLC for its local numbers. You fill in the registration yourself under Settings, Trust center, Register now. You pick a business registration (with an EIN) or a sole proprietor registration (no EIN). Quo says only paid customers can register, not free trials.

Quo builds part of the campaign for you. After you choose your messaging purposes, Quo says it uses them to generate the message examples required for your registration. Quo's business article also says that if you are rejected despite a compliant website, its support team can ask Twilio for clarification. That suggests the registration runs through Twilio, so our Twilio guide is useful background.

Toll-free numbers need a separate, free registration. Quo says each toll-free number is registered on its own, processing can take 2 to 3 weeks, and a rejected toll-free form must be resubmitted within 7 days or the process restarts. The website checks are much the same: a real business site and a visible consent form.

Where does your website go in Quo's registration?

Quo's form has fewer fields than many platforms. Your website carries most of the weight.

The flow, based on Quo's docs:

1. From web or desktop, open Settings, then Trust center, then Register now.
2. Choose business or sole proprietor.
3. Enter your legal name, business type, EIN, full address, industry and website URL.
4. Add a point of contact: name, email, job title and phone.
5. Choose the kinds of texts you will send.
6. Confirm you will not text about prohibited topics.
7. Confirm the fees and submit. Track status as Pending, Approved or Rejected.

What does Quo check on your website?

Quo lists four website criteria. Reviewers reject the registration if your site does not meet them:

• Publicly accessible. Live, not password protected, and not a "coming soon" page.
• Describes your business. What you do and the products or services you offer.
• Shows contact information. Address, phone number, or email.
• Opt-in consent language near forms. Near the submit button of any form that collects phone numbers, saying what people agree to receive, how to opt out, and linking your privacy policy.

Quo's business article adds that the business name in your privacy policy, terms of service and footer should match your registration. It also says your website's phone number and address should match what you submit.

Why was my Quo carrier registration rejected?

Quo shows the rejection reason in the Trust center and in an email. Here are the common reasons Quo lists, paraphrased, with the page that explains each fix.

Quo says a third party verifies your information, so it receives limited detail and has no control over approval. Fix what the reason says, check everything against your tax documents, and resubmit.

How long does review take, and what does it cost?

Quo's main article says most approvals happen within 24 to 48 hours. Some stay pending up to 20 days, and rare cases take more than 30 days. Its business article says carrier review can take 1 to 3 business days, and its FAQ gives 5 to 7 business days to 30 or more. You cannot text US numbers while pending, and Quo says it cannot expedite.

At the time of writing, Quo lists these fees:

Quo-specific gotchas

• One number for sole proprietors. Only one number can text US numbers, and there may be a daily message cap.
• Your Quo number cannot verify a sole proprietor. You need a separate US or Canadian mobile number, not VoIP.
• Caller ID must match. Quo says your Caller ID name must match your registered business name, or it will be rejected.
• Canceling ends registration. If your subscription stays canceled for more than 30 days, you must register again.
