A2P - Standard Brand Registration for 10DLC
To comply with carrier requirements for Application-to-Person (A2P) messaging in the U.S., all businesses using 10-digit long code (10DLC) messaging must register their brand. This article explains the process of registering as a Standard Brand, which is required for most U.S. based businesses with a valid EIN (Employer Identification Number).
What is A2P Standard Brand Registration?
A2P messaging refers to any message sent from an application to a person — for example, automated marketing texts or appointment reminders. To send A2P messages in the U.S., you must register your brand and campaign(s) with The Campaign Registry (TCR) through your messaging provider.
A Standard Brand is designed for businesses registered with an EIN. It allows greater messaging throughput and access to a wider variety of campaign use cases than Sole Proprietor brands.
Note: If your business does not have an EIN and only has one employee per company, please contact support@clinicmonk.com.
Key Benefits of Registering as a Standard Brand
- Higher message throughput compared to Sole Proprietor Brands.
- Required for LLCs, corporations, and most U.S. and Canadian businesses.
- Improved trust score potential through EIN and BN9 verification.
- Enables access to broader campaign use cases.
- Lower chance of carrier filtering or message rejection.
What Are the Requirements for Standard Brand Registration?
Before registering, ensure you have the following:
- Business Legal Name (must exactly match IRS records)
- Valid EIN (Employer Identification Number) – U.S. or Canada BN9 (Business Number)
- Business Type: LLC, Corporation, etc.
- Business Industry
- Official Business Website
- Business Address
- Business Contact Information
- Authorized Representative's Name, Title, Email, and Phone Number
How to Register for A2P as a Standard Brand
Follow these steps carefully to complete your Standard Brand registration:
Step 1: Navigate to Trust Center
- Click on Settings from your sub-account.

- Select Phone System under Business Services.
- Click on the Trust Center tab.

Step 2: Determine Profile Needs
- Click on the Start Registration button under A2P Messaging (SMS) tab.
- Select United States or Canada from the "In which country is your business entity registered?" dropdown.
- Select 'Yes, the business I'm registering has a tax ID' option from the "Does the business you're registering have a tax ID (Ex. US EIN, Canada BN9, etc)?" section.
- Click on Continue.

Step 3: Add Business Details
These details are important for your A2P Approvals: ClinicMonk will submit this information to The Campaign Registry (TCR) during the registration. Based on this information, TCR will approve or reject the registrations, so please make sure all the details exactly match those in your US EIN listing (or your country Tax ID form). If there are any differences - for example, in the business name, number or address - your application would be rejected. DUNS for USA and CCN for Canada are not accepted for A2P Registration.
- Enter Legal Business Name as registered with the Government and mentioned in your tax documents (W2, W9 or CP 575). E.g. ClinicMonk LLC rather than ClinicMonk.
- Enter your Business Type from the list.
- Choose your Business Registration ID Type from the list.
- Enter your Business Registration Number as per your country.
- Select your Business Industry from the list of available industries.
- Enter your Business Email.
- Add your Website URL.
- Select your Business Region of Operations from the list.
- Click on Continue.
Important: A2P Brand registrations using newly generated US EINs (registered in the last 15 days), may be rejected by TCR.
Step 4: Add Business Address
- Select your Country.
- Select your State/Province/Region. (The address provided here should match the address mentioned in the cp575 form (US Only))
- Add Street Address. (Must be a valid address linked to your business. Please don't add a P.O box in the Street Address)
- Add your City. (The address provided here should match the address mentioned in the cp575 form (US Only))
- Enter your Postal/Zip code. (The address provided here should match the address mentioned in the cp575 form (US Only))
- Click on Continue.
Step 5: Add Contact Information of Authorized Representatives
This can be any person that can answer questions about this brand, if needed. Please note that you cannot reuse contact information between brands. Each brand you create must have unique contact information.
- Add Authorized Representative's First and Last Name.
- Add Email Address.
- Add Phone Number.
- Select your Job Position from the list of designations or select Other and type in your designation.
- Click on Continue.
IMPORTANT: Once you click "Continue" or submit your contact details, you may have to validate this through an OTP sent to your email address. It validates each email address by sending a unique 6-digit one-time password to ensure the sender's identity is genuine. This new step strengthens the integrity of brand registrations and helps protect the platform from misuse without disrupting the experience for legitimate users. For more, refer to Email OTP Verification for Secure A2P Brand Registration.
Step 6: Choose Your Business Use Case
The Business Brand Type will be automatically set to "Low Volume Standard" based on the responses provided under Profile Needs.
