10DLC Registration: Brand and Campaign Requirements Explained

Registering for 10DLC should be simple. You fill out a form, tell the carriers who you are, and start texting. In practice, a lot of businesses submit their registration, wait a week, and get back a rejection with a vague error code and no clear idea what went wrong.

Most of those rejections come down to the same handful of issues, and nearly all of them are avoidable if you know what reviewers are looking for. This post walks through the full 10DLC registration process, what information you need for your brand and each campaign, how long it takes, and the mistakes that send applications back to the start.

If you are new to the topic, start with What Is 10DLC? A Plain-English Guide to A2P 10DLC, which covers what 10DLC is and why carriers require it. Here, we are getting into the practical details.

How 10DLC Registration Works

10DLC registration happens in two stages, both submitted to The Campaign Registry (TCR), usually through your texting provider:

1. Brand registration establishes who your business is.
2. Campaign registration describes what you will be texting, to whom, and how they agreed to receive it.

You register your brand once. You register a separate campaign for each distinct messaging use case. After a campaign is approved, your phone numbers are linked to it, and your messages are delivered as verified business traffic.

Most businesses never interact with TCR directly. Your texting platform or CRM collects the information and submits it on your behalf, which is convenient, but it also means your provider’s form is only as good as the details you put into it.

10DLC Brand Registration Requirements

Brand registration is essentially an identity check. Carriers want to confirm that your business is real and that the details you submit match public records. Expect to provide:

• Legal business name, exactly as it appears on your IRS records, not your “doing business as” name or a shortened version.
• EIN or tax ID number, which must match the legal name.
• Business type, such as private company, public company, nonprofit, or government entity.
• Business address and contact information, including an email and phone number for someone who can answer questions.
• Website, which should be live, working, and clearly connected to your business.
• Industry or vertical, which helps carriers apply the right rules to your traffic.
• Stock symbol and exchange, if your company is publicly traded.

Standard Brands vs Sole Proprietors

Businesses without an EIN can usually register through a simplified sole proprietor path. It asks for personal identification details instead of business tax records, but it comes with real limits: typically one phone number, one campaign, and lower daily sending caps. It works well for a solo practitioner sending modest volumes. If you expect to grow, getting an EIN and registering as a standard brand is usually worth it.

Brand Vetting and Trust Scores

After registration, your brand receives a trust score, which carriers use to set your throughput, meaning how many messages you can send per minute or per day. Many providers offer an optional secondary vetting step, a more thorough third-party review of your business, which can raise your score and increase your limits. For businesses planning to send at higher volumes, it is often worth the modest fee.

10DLC Campaign Registration Requirements

Campaign registration is where most applications succeed or fail. This is where you explain what you are sending and prove that recipients asked for it. A complete campaign submission typically includes:

Use Case

You choose a category that matches your messaging, such as customer care, account notifications, delivery notifications, two-factor authentication, or marketing. There is also a “mixed” option for businesses sending a combination of message types. Pick the category that honestly reflects your traffic. Carriers compare what you actually send against what you registered, and a mismatch can get an approved campaign suspended later.

Campaign Description

This is a written explanation of who you are texting and why. Vague descriptions like “customer updates” or “notifications” are one of the most common reasons for rejection. A good description is specific: “We send appointment reminders and rescheduling confirmations to patients who book through our online scheduler.”

Sample Messages

You will provide examples of the actual texts you plan to send. Each sample should include your business name, reflect your registered use case, and include opt-out language like “Reply STOP to unsubscribe.” Reviewers also tend to flag public link shorteners, since spammers use them to disguise destinations.

Opt-In Method (Message Flow)

This is the heart of the review. You need to explain exactly how people consent to receive your texts, whether that is a website form, a checkout checkbox, a keyword they text to your number, or a paper form. Reviewers want details: where the opt-in happens, what the disclosure language says, and proof that consent is collected before any messages are sent. If your opt-in lives on a website, make sure the page is live and publicly viewable.

Strong opt-in language usually names your business, describes the kind of messages people will get, mentions that message frequency varies, that message and data rates may apply, and explains how to opt out. A checkbox, if you use one, should never be pre-checked.

Opt-Out and Help Keywords

Your campaign needs to handle standard keywords like STOP (to unsubscribe) and HELP (to get support information). You will usually provide the automatic replies people receive when they text those words. Your HELP response should include a way to actually reach your business, like a phone number or email.

Privacy Policy and Terms

This requirement has gotten stricter. Your privacy policy needs to be publicly accessible and should state that mobile phone numbers and consent information are not shared with third parties or affiliates for marketing purposes. Twilio’s documentation on privacy policy rejections lists the most common reasons a policy fails review, including missing that statement or linking to conflicting policies. Many providers now also require a link to your terms and conditions as part of every new campaign submission.

Content Attributes

You will also be asked yes-or-no questions about your messages, such as whether they include links, phone numbers, or age-restricted content. Answer honestly. Saying “no links” and then sending links is an easy way to get flagged.

How Long Does 10DLC Registration Take?

Timelines vary by provider and carrier workload, but a rough guide:

• Brand registration: often a few business days, sometimes faster.
• Campaign review: anywhere from a couple of days to a few weeks.

The biggest factor is whether your submission is clean on the first try. Each rejection sends you back into the review queue, so an incomplete application can easily turn a few days into a month. If you have a launch date for a texting program, start registration well before it.

Common Reasons 10DLC Registrations Get Rejected

After reading through provider documentation and support guides, the same problems come up over and over:

• Business details don’t match public records. The legal name and EIN must line up exactly.
• The website is broken, under construction, or unrelated to the business being registered.
• The campaign description is too vague to tell what the messages are actually for.
• The opt-in explanation is unclear, or the opt-in page can’t be viewed.
• Sample messages are missing the business name or opt-out language.
• The privacy policy is missing, hard to find, or allows sharing mobile information with third parties.
• The phone numbers came from a purchased or shared list. Carriers expect consent to be collected directly by your business.
• The content falls into a restricted category. Certain industries and message types face extra scrutiny or aren’t allowed at all.

Bandwidth’s help center has a practical guide to 10DLC campaign vetting tips that is worth reading before you submit, even if you use a different provider, since the underlying carrier expectations are the same.

Registration Isn’t a One-Time Task

Getting approved is not the finish line. Carriers monitor traffic after approval and compare it against your registered campaign. If you start sending promotions under a campaign registered for appointment reminders, or your opt-out and complaint rates spike, your campaign can be filtered or suspended.

A few habits help keep you in good standing:

• Register a new campaign when you add a genuinely new type of messaging.
• Keep your opt-in pages, privacy policy, and terms live and up to date.
• Honor opt-outs immediately.
• Review your registration whenever your business name, website, or messaging program changes.

Does 10DLC Registration Apply to RCS?

If you are exploring RCS for richer, branded messages, you will go through a separate brand verification process for that channel. But RCS doesn’t replace your 10DLC registration. When a customer’s phone can’t receive RCS, messages usually fall back to SMS, and that fallback traffic still needs to be registered. I cover how the two channels compare in RCS vs. SMS: What Businesses Need to Know.

A Quick 10DLC Registration Checklist

Before you hit submit, confirm that you have:

• Your exact legal business name and matching EIN
• A live website that clearly represents your business
• A specific, plain-language campaign description
• Sample messages that include your business name and opt-out instructions
• A clear, viewable opt-in process with proper disclosure language
• STOP and HELP responses, with real contact details in the HELP reply
• A public privacy policy that says mobile information isn’t shared for marketing
• A link to your terms and conditions

The Bottom Line

10DLC registration is less about paperwork and more about proof. Carriers want to know that your business is real, that your messages match what you told them, and that every person you text actually asked to hear from you. If you can show all three clearly, approval is usually straightforward. If any piece is vague or missing, expect a rejection.

Take the extra hour to get your submission right the first time. It is far faster than waiting in the review queue twice.
