10-digit long code registration and validation is sweeping business SMS, creating a safer, less spammy playing field for texting. But the process can be complicated (and a little annoying). So, we’re here to break it down.

What is 10DLC?

10DLC refers to the 10-digit long code phone numbers your business uses to text or call customers.

Recently, the national mobile carriers (think Verizon, AT&T and T-Mobile) started a program to regulate business texting from these 10-digit phone numbers. The idea is to provide greater transparency into the use of Application to Person texting from businesses to their subscribers (your customers). The program is also meant to offer up better protections for both businesses and customers and eliminate spam.

This is an industry-wide requirement for business texting. Any business that texts from a standard phone number must register, regardless of the texting platform. Shortcodes and Toll-Free numbers are not regulated by the 10DLC standards.

Why are carriers implementing 10DLC registration regulations?

The mobile carriers want to prevent spammers from taking advantage of businesses and their customers.

Simply put, mobile carriers are trying their hardest to avoid following in email’s footsteps.

How many emails do you have in your inbox at this minute? 10? 100? 10,000? And how many of those emails are you actually reading and engaging with each day? Chances are you’re skimming or skipping a huge majority of them.

Texting sheds the excess weight of your corpulent, pernicious inbox. And mobile carriers in the US want to keep it that way.

To register you’ll need to provide details about your business and brand. Then, it’ll require Campaign Use Cases, which break down how you intend to use your business texting. And finally, you’ll need to provide a few sample messages your brand would send customers using your 10DLC number.

What will I need to register a 10DLC number?

Registering your brand is a one-time setup. You’ll need to provide information that matches precisely to your tax documentation. Please make sure this info is absolutely accurate and free of any misspellings.

Here’s a list of the information you’ll need to register your line:

  • Your legal business name
    • Make sure this matches exactly to your tax documents. If you miss including “LLC” or change your capitalization or have other inconsistencies, your registration may not be accepted and you’ll have to resubmit.
  • The name your company is doing business as
  • Your business address
  • Your company’s tax number/ID/EIN
    • If you are a SOLE-PROP using your social security number for tax purposes: we recommend you go through the process to obtain an EIN and then resubmit your 10DLC Registration. It is very easy to get a EIN and only takes a few moments. You can do so here: https://irs.ein-tax-id-number.com/application/
  • Your business industry and type (private, publicly traded or nonprofit)
  • Your Stock Symbol if applicable
  • Your company’s website
  • Your primary contact’s details

You’ll also need to provide descriptions of your use cases and sample messages for each type of campaign you run.

The vast majority of Textel clients typically fall into one (or more) of four campaign use case types. Those are:

  • Sole Proprietors. This campaign type is available for customers who don’t have an EIN/tax number. These customers are limited in their throughput.
  • Customer Care. These texts include customer interactions, including account management and customer support.
  • Marketing. This type of campaign use case includes marketing or promotional content. That might be sales notifications, discount codes, and the like.
  • Higher Education. This is messaging on behalf of colleges or universities, but also includes school districts and any educational institution. This use case is not for the “free to the consumer” messaging model.

If you select more than one of these use cases, your campaign choice will be registered as “Mixed.”

Other standard use cases may include:

  • Two-Factor Authentication
  • Account Notifications
  • Delivery Notifications
  • Fraud Alert Messaging
  • Low Volume Mixed
  • Mixed
  • Polling and Voting
  • Public Service Announcements
  • Security Alerts

What Happens When My Registration is Submitted?

While your submission might sound a little overwhelming, don’t freak out – we’re here to help!

Once you’ve submitted your registration to us, we’ll work with our carrier partners to complete the registration process for you with The Campaign Registry. TCR will locate and confirm the existence of the company you submitted by checking against several databases and using best-practice, third-party verification vendors. The following information must be verified in order for your brand to obtain a “verified” status:

  • EIN/ Tax ID
  • Legal Company Name
  • Legal Company Address

The check will also look to see:

  • If your brand is a tax-exempt organization if the “non-profit” entity type is selected
  • If your brand is part of the Russell 3000 list.

It can take up to five days for verification, depending on volume and approval times. It’s important to note that accuracy matters. Any typos or outdated information can significantly affect your verified status.

If your brand fails the vetting process, you’ll need to resubmit your data, correcting any inaccuracies or inconsistencies.

If you choose not to register, your text message traffic will be subject to filtering and may be blocked or rejected.
