What is A2P 10DLC?

A2P 10DLC stands for Application-to-Person 10-Digit Long Code. It’s a U.S. messaging system that allows businesses to send SMS/MMS from standard 10-digit phone numbers, similar to normal local numbers, but with higher throughput and better deliverability than traditional long codes.

Why register 10DLC?

Businesses are required to register for A2P 10DLC because U.S. mobile carriers want to verify who is sending messages and what type of content they’re sending. This verification helps prevent spam and fraud, protects consumers, and ensures that only legitimate businesses use the messaging system. Registration also allows carriers to assign the proper message throughput and trust levels, which improves deliverability and reduces the chances of messages being blocked. Without registration, carriers treat the traffic as unverified and potentially harmful, so they heavily filter or even stop those messages from going through.

Who needs to register?

Who needs to register will depend on how you’d like to use Ringo:

• For calling and sending SMS/MMS messages - yes you need to do carrier registration

• For WhatsApp only use - no, you don’t need to register with 10DLC, however you need to do your WhatsApp Setup to be able to send message templates.

How long does it take?

The total registration timeline can differ from one case to another. Many applications are approved within 5–7 business days, while some may stay in a pending state for up to 30 days. In uncommon situations where important details cannot be confirmed quickly, the process may extend beyond 30 days. During this waiting period, you will not be able to send messages to U.S. numbers, but you can receive messages and calls.

Register with Ringo

Who can manage?

Only the account owner and admins can do US carrier registration, members do not have access to it.

How to access?

Option 1: During the Ringo onboarding process, after choosing your phone number and setting up your AI assistant, you can register directly by selecting “10DLC Registration”

Option 2: You can also register at any time by going to Settings and scrolling down to “US Carrier registration.”

Registration approval

Once you go through the process and your carrier has approved your registration we will send you a notification.

If your registration is rejected

You may need to revise your details and resubmit. Carriers treat each submission as a new review, so additional fees may apply.

Verification is performed by an external company, so we do not influence the outcome of your application. The details we receive about the decision are limited. However, you can view the rejection reason directly on the Ringo app. Use that information to make any necessary updates and submit your application again for approval.

Registration Process with Tax ID Number

To register with 10DLC the first step is knowing if you have a business with a Tax ID or not. If you do have a business with either EIN, SSN or any tax identification number please follow the steps below. If you don't have a Tax ID please check Registration with no Tax ID here.

Step 1 - Intro

Path 1: Businesses With an EIN

Choose this option if your business has an EIN, SSN, or any official U.S. tax identification number.

To complete registration, you will need:

• A valid business address that matches your tax registration

• A company website or publicly searchable business listing

• Standard business details (name, industry, type, description, and contact information)

This path is recommended for LLCs, corporations, partnerships, and any registered business entity with federal or state recognition.

Path 2: Without an EIN (Sole Proprietorship)

Choose this option if you do not have an EIN.

If you are unsure what an EIN is, you likely do not have one and should take this path.

Requirements:

• A U.S. or Canadian residential address

• A working mobile phone number that is not your Ringo number

• Personal contact details rather than business registration information

This path is designed for individuals operating as sole proprietors without formal business registration.

Step 2 – Business Information

To verify your identity, carriers require detailed information about your business. You will need to enter:

• Legal business name

• Business type and company type

• Industry

• A short description of what your business does

• A valid contact information

• Primary point of contact details (name, email, phone)

Ensure all information matches your official business registration documents.

Step 3 – Business Address

International businesses must provide a valid mailing address.

You will need to enter:

• Country of residence

• Street address

• City

• Postal code

This must match your registered business information in your home country.

Step 4 – Campaign Information

1. Campaign description

This is where you provide a clear summary of your campaign’s purpose and messaging goals. Carriers use this description to understand why you are sending messages, who receives them, and what types of content you deliver.

Tips for a strong campaign description:

• Be specific about your messaging purpose and goals

• Describe your target audience and who will receive the messages

• Mention message frequency and timing (daily, weekly, event-based, etc.)

• Include the types of messages you plan to send (alerts, reminders, updates, marketing, etc.)

• Reference your business type and industry for additional context

• Aim for 100–200 characters. Minimum 40 characters required for approval

Good examples:

• Customer Service:

  “We send customer service notifications to existing customers who have opted in. Messages include order updates, appointment reminders, and support responses. We send 2–5 messages per week per customer.”

• Delivery Updates:

  “We provide real-time delivery status updates to customers who place orders on our e-commerce platform. Messages include order confirmation, shipping updates, and delivery completion. Customers receive 2–4 messages per order.”

• Account Alerts:

  “We send account security alerts and transaction notifications to banking customers. Messages include login alerts, payment confirmations, and fraud prevention notices. Messages are sent only when account activity requires it.”

Common mistakes to avoid:

• Too vague:

  “We send messages to customers.”

  → Does not explain purpose, message types, or frequency.

• Too brief:

  “Marketing messages for sales.”

  → Under 40 characters and missing details about audience and timing.

• Missing context:

  “Notifications.”

  → No information about business type, audience, or what the notifications contain.

2. Message Flow

This is where you will describe how your end-users can opt-in to receive messages.

  Example: “I agree to receive SMS messages from X Business.”

• Message and data rates disclosure – Inform users that standard carrier messaging and data rates may apply for SMS communications.

• Reply keywords to opt out – Provide clear unsubscribe instructions.

  Example: “Reply STOP to opt out at any time.”

• Link to privacy policy – Include a clickable link to your privacy policy explaining how user data is collected, stored, and used.

Where to Include

Businesses must present these consent elements at every point where users provide their phone numbers. The opt-in should be clear, unambiguous, and placed before the user submits their information. Common places to include the required consent language are:

• Website sign-up forms – Include the consent checkbox, opt-out instructions, and privacy policy link directly beneath the phone number field.

• Checkout or registration pages – If you collect phone numbers during customer account creation or purchase flows, consent must appear at the same point.

• Lead capture forms and landing pages – Any form requesting a phone number for marketing, alerts, or support must include the full consent wording.

• Mobile app onboarding – If your app collects phone numbers, show the consent checkbox and notices on the same screen where the user enters their number.

• In-person or verbal opt-in scenarios – You must provide a digital or written version of the consent language, and users must actively agree before receiving SMS.

• After-hours or chat support widgets – If the widget collects a phone number for follow-up SMS communication, include the consent text above the “Submit” button.

Including the consent requirements at the exact moment of phone number collection ensures compliance with carrier regulations and reduces the risk of campaign rejection.
