What is 10DLC and why does your organization need it?

Text messaging is one of the most effective ways to reach supporters, members, and volunteers. Open rates are dramatically higher than email. Response rates are better. People actually read texts.

But before your organization can send SMS campaigns at any real scale, carriers require you to complete a registration process. That process is called 10DLC — and if you've just encountered it for the first time, you're probably wondering why something that sounds so technical is standing between you and sending a text message.

Here's what it is and why it matters.

What 10DLC actually means

10DLC stands for 10-Digit Long Code — which is just a technical way of saying a standard phone number that's been registered and approved for organizational texting.

For a long time, anyone could buy a phone number and immediately start sending mass texts. That was fine until spammers figured out the same thing. To protect consumers from unwanted messages, mobile carriers introduced a registration system that requires organizations to identify themselves, explain how they collect consent from recipients, and describe the types of messages they'll be sending.

The idea is straightforward: carriers want to know who's sending messages and whether those messages are legitimate. Registered organizations get better deliverability. Unregistered senders get filtered out. It's less a bureaucratic hurdle and more a baseline of accountability that benefits everyone — including your supporters who would rather not get spammed.

Why does ActivistCentral require it?

Because the carriers do. This isn't an ActivistCentral policy — it applies to every modern texting platform. Without completing registration, your messages may be filtered, throttled, or blocked by carriers before they ever reach a recipient. Completing the process is what gives your outbound texts the best chance of actually landing.

Why does it feel so complicated?

Because several different organizations are involved behind the scenes, and most people encounter this process without any prior context for how it works.

Depending on your organization type, the approval chain can include your texting provider, The Campaign Registry, individual mobile carriers, and — for many political organizations — a separate body called Campaign Verify. You don't need to become an expert in how all of these systems interact. But understanding that multiple parties are involved helps explain why the process takes time and why a single missing piece of information can create delays.

Political organizations have an extra step. If your organization is involved in electoral campaigns or political advocacy, you'll likely need Campaign Verify approval in addition to standard 10DLC registration. The next article covers this in detail.

The most common reasons applications get delayed

Most delays aren't technical. They're caused by missing or inconsistent information — the kind of thing that's easy to fix once you know what reviewers are looking for. These are the issues we see most often.

No privacy policy on your website. Carriers want to know how your organization collects, uses, and protects personal data. If your website doesn't have a privacy policy, approval will stall. This is the single most common issue.

No SMS consent language on your forms. If you collect phone numbers through a web form, visitors need to understand they may receive text messages. That disclosure needs to be present and visible — not buried in fine print.

No opt-in checkbox. Consent to receive SMS should be explicit and optional. A phone number field alone isn't enough. Reviewers expect a clear, unchecked-by-default checkbox that lets people actively choose to receive texts.

Privacy policy not linked from your form. Having a privacy policy page isn't always sufficient. Reviewers often expect it to be directly accessible from the form where you're collecting consent — not just findable somewhere on the site.

Mismatched information. If your registration says one thing and your website says another — different org name, different contact info, different description of what you do — reviewers will flag it. Consistency across everything you submit matters.

How long does approval take?

It varies, and there's no universal timeline. Standard approvals can move relatively quickly when everything is in order. Political organizations with Campaign Verify requirements often take longer. Any corrections or resubmissions add time.

The most important thing you can do is start early. Organizations that submit with complete, consistent information — privacy policy in place, consent language on their forms, registration details that match their website — generally have the smoothest experience. Organizations that submit and then scramble to fix issues after the fact end up waiting longer.

You don't have to wait to use the platform. While your SMS registration is in progress, you can keep building — import contacts, create lists, configure email, set up campaigns. Approval running in the background doesn't slow down everything else.

Start earlier than you think you need to

If there's one piece of advice that applies to every organization going through this process, it's this: don't wait until the week before a campaign to start your registration. Approvals take time even when everything goes smoothly, and if something needs to be corrected, you want that buffer.

Before you submit, make sure your website has a privacy policy, your forms have proper SMS consent language, and your registration information is consistent with what's on your site. The next article — the Political SMS Compliance Checklist — goes through each of these requirements in detail so you can verify everything before you submit.

Once your registration is complete, you generally won't think about it again. The compliance work happens once so you can spend the rest of your time doing what actually matters: reaching the people who support your mission.
