How to Build an Approval-Ready 10DLC Submission (And Avoid the Most Common Rejections)
Most 10DLC rejections are preventable. That’s not a minor observation — it’s the single most important thing to understand before you sit down to register your brand and campaign with The Campaign Registry. The businesses that get stuck in approval limbo, dealing with vague rejection codes and repeated resubmissions, almost always share the same root problem: they submitted before they were truly ready.
The gap between a campaign that sails through 10DLC registration and one that comes back with errors is rarely a matter of luck. It’s a matter of preparation. Carriers and The Campaign Registry have defined expectations about what a compliant, trustworthy messaging program looks like — and when your submission matches those expectations across every required element, approvals happen faster, trust scores come in higher, and your program launches without the delays that cost businesses both time and deliverability.
This guide walks through exactly what goes into an approval-ready 10DLC submission: what carriers are looking for, where most businesses fall short, and how to align every component of your registration before you submit.
Why 10DLC Rejections Happen in the First Place
Before getting into the specifics of what a strong submission looks like, it’s worth understanding the structure that governs 10DLC registration — because the reasons for rejection almost always trace back to a mismatch between what a business submits and what that structure requires.
10DLC, or 10-digit long code, is the carrier-backed framework for business-to-person (A2P) SMS messaging in the United States. Every business that wants to send commercial text messages through a standard 10-digit phone number must register their brand and each messaging campaign with The Campaign Registry (TCR), which acts as the central hub connecting messaging providers, carriers, and businesses.
Carriers use TCR data to evaluate the legitimacy and intent of messaging programs before deciding how to route and score them. A rejection doesn’t necessarily mean your business is doing something wrong — it often means that your submission didn’t give the registry and carriers enough of the right information to make a confident assessment. That’s a documentation and preparation problem, and it’s entirely fixable.
Component 1: Brand Registration Details
Your brand registration is the foundation of your 10DLC submission. It establishes your business identity with The Campaign Registry and directly affects the trust score your campaigns receive. Errors or inconsistencies at this stage ripple through everything that follows.
The most important rule for brand registration is consistency. The legal name, EIN (Employer Identification Number), address, and other business details you submit to TCR must exactly match what appears in official business records — IRS filings, state registration documents, and your public-facing business information. Even minor discrepancies, like an abbreviated name or a mismatched address format, can trigger review delays or outright rejections.
Before submitting, verify your EIN documentation, confirm your registered legal name as it appears with the IRS, and double-check that your business address matches across your registration documents and your website. Businesses that take this step seriously before submitting almost always have smoother brand registration outcomes.
It’s also worth noting that the type of business entity you register matters. Sole proprietors, LLCs, corporations, and nonprofits all go through slightly different registration paths, and some entity types have access to higher trust score tiers than others. Understanding where your business fits in that structure before you register helps you set accurate expectations for the trust score you’ll receive — and the daily messaging volume that comes with it.
Component 2: Campaign Use Case Descriptions
If brand registration is the foundation of a 10DLC submission, the campaign use case description is where most businesses lose points — and most rejections originate.
Your use case description tells carriers what your messages are for, who they’re going to, and why those recipients have agreed to receive them. It needs to be specific, accurate, and aligned with one of the approved 10DLC use case categories. Generic descriptions like “marketing messages” or “customer communications” consistently underperform. Carriers are looking for clarity about the actual content and purpose of your campaigns.
A strong use case description answers several questions directly: What type of messages will you be sending? What action or relationship triggers each message? What is the audience — existing customers, leads, loyalty members? What specific call to action or information does each message contain?
The more precisely your description maps to a recognized use case category and the more clearly it conveys that your messaging program serves a real, legitimate business function, the more confidently carriers can approve and score your campaign.
One additional pitfall to avoid: don’t register a use case that doesn’t accurately reflect what you’ll actually be sending. Carriers monitor message content after approval, and a mismatch between your stated use case and your actual messages can result in campaign suspension, filtering, or penalties that are far more disruptive than a pre-submission rejection.
Component 3: Sample Messages
Sample messages are your opportunity to show carriers exactly what your subscribers will receive — and they’re scrutinized closely. Every sample message submitted with your 10DLC campaign registration should reflect what you’ll actually send, include all required compliance elements, and clearly align with your stated use case.
The non-negotiable compliance elements for SMS marketing messages include: clear business identification (your brand name in or near the message), opt-out language (typically “Reply STOP to unsubscribe” or equivalent), and — for promotional content — disclosure that message and data rates may apply.
Beyond compliance language, carriers evaluate whether your sample messages feel like legitimate business communications. Messages that are overly promotional in tone, use spam trigger language, make unrealistic claims, or include shortened URLs from unknown domains are red flags that can trigger rejection or suppress your trust score.
Write your sample messages the way your actual messages will read. If you’re sending appointment reminders, your samples should look like appointment reminders. If you’re sending promotional offers, your samples should reflect the tone and content of those offers — with all required disclosures present. The goal is to leave no ambiguity about what you’re sending and why it’s appropriate.
Component 4: Opt-In Documentation
Opt-in documentation is one of the most commonly overlooked components of 10DLC registration — and one of the most consequential when it’s missing or incomplete.
Carriers require that you document how subscribers are consenting to receive your messages. This means describing your opt-in method (web form, keyword text, point-of-sale enrollment, etc.), and confirming that the opt-in language presented to subscribers clearly discloses that they’re agreeing to receive text messages, identifies your brand, and meets TCPA requirements for prior express written consent.
If your opt-in method is a web form, that form needs to be live, accessible, and compliant at the time of submission. Carriers may review it directly. The opt-in language on the form should not be buried in a privacy policy or presented in a way that could be construed as ambiguous — it needs to be clear, prominent, and specific to SMS consent.
The method you use to collect consent also matters for your trust score assessment. Double opt-in — where subscribers confirm their enrollment by replying to a verification text — provides a stronger, more defensible consent record and is looked upon more favorably by carriers when evaluating campaign submissions. If you’re currently using single opt-in, your documentation needs to be particularly tight to compensate for the reduced verification layer.
Businesses that go into a 10DLC submission without current, compliant opt-in processes in place often face rejection specifically around consent documentation — a problem that requires fixing the underlying process before resubmitting, not just updating the paperwork.
Component 5: Website Compliance
Your website is reviewed as part of the 10DLC vetting process, and there are specific elements carriers and TCR expect to find. Missing any of them is a straightforward path to rejection.
At minimum, your website should include:
A Privacy Policy that addresses how you collect, use, and protect consumer data, including mobile phone numbers. The policy should explicitly address SMS communications and confirm that subscriber information is not sold or shared with third parties for their own marketing purposes.
Terms and Conditions (or Terms of Service) that cover your messaging program, including the nature of the messages sent, frequency expectations, and how subscribers can opt out.
Visible SMS Opt-In Disclosure on any page or form where mobile numbers are collected. This disclosure must clearly state that by submitting their number, the user is consenting to receive text messages from your business — and it must identify your brand by name.
A functioning, professional website that reflects the legitimate business described in your brand registration. Carrier reviewers are evaluating whether your website looks like an actual operating business. Placeholder pages, broken links, missing contact information, or websites that don’t match the registered business name can all raise red flags.
Review your website through the lens of a carrier vetting your program for the first time. Does it clearly establish who you are, what your business does, and how you’re collecting consent from the people you’ll be texting? If the answer to any of those questions requires digging, your website needs work before you submit.
The Cost of Getting It Wrong
The business case for investing in preparation before submission isn’t complicated. Every rejection adds time — often days or weeks — before your campaign can be active. Every resubmission cycle means your messages aren’t reaching customers who opted in to hear from you. And persistent issues with your TCR registration can affect your trust score in ways that cap your daily messaging volume long after your campaign is technically approved.
Beyond the operational delays, there’s a compliance dimension. Businesses that try to work around 10DLC requirements rather than meeting them correctly the first time often end up in a worse position — with suppressed messages, carrier filtering, or flagged accounts that require significant remediation to resolve.
The time investment in building an approval-ready submission is small compared to the cost of doing it wrong.
Get Your 10DLC Registration Right the First Time
10DLC compliance doesn’t have to be complicated — but it does require getting the details right. Brand identity, use case clarity, compliant sample messages, opt-in documentation, and website readiness all need to be aligned before you submit, not patched together after a rejection comes back.
