Introduction to A2P 10DLC Registration for SMS Marketing

Text messaging is an extremely effective channel for customer engagement and sales. But recent regulations around A2P 10DLC compliance aim to cut down on spam texts and require clear consumer consent.

As a brand using SMS marketing, it's crucial you understand and comply with A2P 10DLC registration to continue messaging customers legally.

If you've been experiencing deliverability issues with your SMS messages, you're not alone. Many businesses face this challenge, but the good news is, you've landed in the right place to find a solution. Let's explore how to navigate these waters and ensure your messages reach their intended recipients, every time.

At Chatform, we are experts in guiding brands through A2P 10DLC registration. By partnering with us, we handle compliance on your behalf and ensure your SMS program stays up and running.

This comprehensive guide will explain everything brands need to know about A2P 10DLC, including:

What is A2P 10DLC?

A2P stands for “Application to Person” and refers to automated texts sent from a business platform to customers’ mobile phones.

10DLC means 10-digit long codes - these are standard 10-digit local phone numbers used for business purposes like sales, marketing, notifications, alerts and more.

A2P 10DLC registration is required by US law for any business utilizing a 10DLC number to send automated texts to consumers.

Without proper registration, texts may be blocked by major carriers like Verizon, AT&T, T-Mobile, and others.

Why A2P 10DLC Registration Matters

Compliance with A2P 10DLC is not optional - it is mandatory for any brand using text messaging. Here are some key reasons it's crucial to register:

  • Legal compliance - All companies sending automated texts must complete A2P 10DLC registration to comply with the law. Violations can lead to lawsuits and blocking.
  • Protects consumer privacy - Registration verifies you have obtained consumer consent properly and helps cut down on spam texts.
  • Maintain open engagement channels - With 98% open rates, texting is essential for engaging customers. Registration keeps this channel available.
  • Avoid blocking - Carriers are filtering more unregistered traffic which could block your texts to customers!

Essentially, A2P 10DLC compliance allows brands to keep texting customers legally, ensure deliverability and maintain this highly effective engagement channel.

The A2P 10DLC Registration Process

Registering for A2P 10DLC requires working with a trusted messaging partner to complete the process across four key steps:

1. Business Identity Verification

This involves submitting official business documents and info like:

  • Tax ID
  • Website URL
  • Physical address
  • Industry/type of business

This verifies to regulators that you are a valid, registered business entity.

Note that If you do not have a Tax ID there is still hope. You can submit specified information that is required for brands that do not have a Tax ID.

2. Secure Brand Approval

Your compliance partner will submit your business info to the appropriate telecom regulators and request brand approval.

This step essentially verifies that you are a legitimate, operating business. Brand approval is required to move forward.

3. Define Messaging Use Cases

Here you will outline your specific use cases for text messaging customers. For example:

  • Promotions and sales
  • Alerts and reminders
  • Event updates
  • Appointment confirmations
  • Shipping notifications
  • Customer support

Be as accurate as possible in defining use cases, as exceeding them later can warrant re-approval.

You'll also need to provide example text scripts for approval to illustrate your use cases.

4. Confirm Opt-In Consent Process

An essential part of the application is detailing how customers consent to receive your texts.

Regulators will specifically look for proof of opt-in consent before approving a campaign. More on this below.

Once submitted, the average A2P 10DLC approval timeline is currently 1-2 months due to backlogs (as the regulations go in to effect, every brand is rushing to register). So it's best to start the registration process right away.

Defining Messaging Use Cases

One of the most important parts of securing A2P 10DLC approval is outlining your intended use cases for texting customers.

Regulators want to know exactly how you plan to message subscribers to prevent misuse and spam.

Here are some tips for defining compliant use cases:

  • Be specific - Explain precisely how you will text customers whether for promotions, updates, reminders, alerts etc. Don't overreach what you will actually do.
  • Start narrow - It's recommended to start with a narrower initial use case, like alerts only. Once approved, you can expand to more use cases.
  • Provide examples - Supply regulators sample text scripts that match your use cases. This further illustrates legitimate messaging.
  • Be consistent - Only text customers in the ways outlined in your approved use cases. Straying from approved use cases risks non-compliance.
  • Get re-approved for new campaigns - If you want to add new text messaging campaigns later beyond your initial approved use cases, you'll need to get re-approved by regulators.

Following these best practices ensures your defined use cases comply with A2P 10DLC regulations.

Gaining Opt-In Consent

The other critical component regulators look for is proof of consumer opt-in consent.

Obtaining clear opt-in consent is mandatory before sending customers automated texts.

Here are some tips for securing compliant opt-in consent:

Have Opt-In Language on Website Forms

Any web form where customers provide their phone number should include clear opt-in language, like:

  • "By submitting this form, I consent to receive text messages from [Company] at the number provided."
  • "I agree to receive recurring automated text messages from [Company] on updates, promotions, and alerts."

Regulators will check your website and forms to verify clear opt-in language is present before approving A2P registration.

Allow Instant Opt-Out

Include clear opt-out instructions in all texts sent so customers can instantly opt out if they change their mind. For example:

  • "Reply STOP to opt out."

Honor and document all opt-out requests immediately.

When using a platform like Chatform all these requirements to stay compliant are already adhered to.

Pick an A2P Compliance Partner

While A2P 10DLC registration is mandatory for SMS marketing, the process can be complex for brands to handle on their own.
