Before you steam ahead in submitting your A2P Brand or Campaign registration, here's some good-to-know information that will ensure you understand what A2P registration is, and whether it is required based on your needs.
Some countries require legal documentation before a number can be activated. These are industry regulations, not something Ivorey
controls, and are handled via third-party review.
If you want to register phone services in the United States or Canada through Ivorey
, then A2P 10DLC registration is a legal requirement. A2P means "Application-to-Person" and 10DLC is your 10-Digit Long Code (your standard business phone number).
You'll need to purchase and complete A2P registration, which verifies your business as a legitimate sender for SMS and helps you to stay compliant and avoid being flagged as spam.
After you register, your brand gets a Trust Score. It tells carriers how trustworthy your brand is. Higher scores = higher message throughput (faster and more reliable sending).
Your Trust Score is based on:
Whether your info matches across your website, brand name, and messages
How transparent you are about opt-in and opt-out
Your messaging history
This guide is perfect if you're looking to:
Complete your A2P Registration so you can make phone calls and/or send SMS's in the USA or Canada
Make sure you have the following items ready:
Registration fee of $15 USD (passed onto third party provider)
Business Legal Name (must exactly match IRS records)
Valid EIN (Employer Identification 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
The most common reason A2P applications get rejected isn't missing information, it's inconsistencies between your opt-in form, your campaign description, and your website. Read through the recommendations below carefully before submitting.
Your opt-in form must include two separate consent checkboxes with very clear wording to explain what they are agreeing to. Here is the recommended wording:
Marketing opt-in:
"I consent to receive marketing text messages, about special offers, discounts, and service updates, from [Business Name] at the phone number provided. Message frequency may vary. Message & data rates may apply. Text HELP for assistance, reply STOP to opt out."
Non-marketing opt-in:
"I consent to receive non-marketing text messages from [Business Name] about [description of use case, e.g. appointment reminders and booking confirmations]. Message frequency may vary. Message & data rates may apply. Text HELP for assistance, reply STOP to opt out."
Both checkboxes must be:
Optional - the form must be submittable even if neither box is checked
Not pre-checked - the contact must actively choose to opt in
Acting on selection - you must only send the communication type a contact has consented to (marketing or non-marketing)
Note: The [Business Name] used in your checkboxes must exactly match the name on your CP 575/147C document.
Note for DBAs: If you operate under a different brand name to your registered business name, add the following to your Campaign Use Case Description: "We are doing DBA as [Brand Name]." Make sure your DBA relationship is clearly stated on your website - typically in your Terms & Conditions. If it can’t be found, your application may be rejected.
Campaign Specifics
Your campaign description must directly align with the language in your consent checkboxes, and must make sense for your type of business.
If your campaign includes appointment reminders or service notifications, your non-marketing checkbox must reference those specific message types - not just say "non-marketing messages"
If your campaign includes special offers or discounts, your marketing checkbox must reference those - not just say "marketing messages"
Your campaign use case must match your business model. For example, using an "appointment reminder" use case for a business that doesn't take appointments will be flagged
Privacy Policy
Your Privacy Policy must be linked in the footer of your opt-in form, and must include a non-sharing clause. Here is the recommended wording:
"No mobile information will be shared with third parties/affiliates for marketing/promotional purposes. Information sharing to subcontractors in support services, such as customer service, is permitted. All other use case categories exclude text messaging originator opt-in data and consent; this information will not be shared with any third parties."
Note: Your Privacy Policy must never reference the selling, buying, or sharing of leads.
Terms of Service
Your Terms of Service must include the following terms, customised for your business:
Your Business Name
Brief description of the kinds of messages users can expect to receive when they opt in. For example:
You can cancel the SMS service at any time. Just text "STOP" to [Phone Number]. After you send the SMS message "STOP" to us, we will send you an SMS message to confirm that you have been unsubscribed. After this, you will no longer receive SMS messages from us. If you want to join again, just sign up as you did the first time and we will start sending SMS messages to you again.
If you are experiencing issues with the messaging program you can reply with the “HELP” for more assistance, or you can get help directly at [support email address or toll-free number].
Carriers are not liable for delayed or undelivered messages.
Message and data rates may apply for any messages sent to you from us and to us from you. You will receive [message frequency]. If you have any questions about your text plan or data plan, it is best to contact your wireless provider.
If you have any questions regarding privacy, please read our privacy policy: [link to privacy policy]
The approval process can be tricky. Please make sure all your information is accurate and consistent. Incorrect or inconsistent details are the #1 reason applications get rejected. New EINs (issued in the last 45 days) are also often rejected. Consider waiting or submitting supporting documents in this case.
From the Ivorey main menu, go to [Settings] > [Phone Services] > [Trust Center] > and under A2P Messaging, click the [Start Registration] button
If your business has a Tax Number (EIN for the US, CCN for Canada, etc.), please select [Yes, the business I’m registering has a US EIN] (Standard Low Volume Brand Registration)
If your business does not have a Tax Number but operates from a valid Business Address in the US/Canada, please select [No, the business I’m registering does not have a US EIN] (Sole Prop Brand Registration)
If your business does not have a Tax Number and the business address is not in US/Canada, unfortunately you cannot proceed with A2P Brand Registration. In this case, the best alternative would be to use Toll-Free numbers

Click [Proceed] to submit your application, without addressing the issues outlined in the compliance review
Click the X or [Back] button, to address the issues and proceed
Note: While this compliance review is designed to reduce common causes of rejection, the feedback and suggestions provided do not guarantee carrier approval.
When you're ready, click [Submit]
After you hit Submit on your A2P Brand registration application:
Your application goes for third party approval. This process can take up to 2 weeks, but is usually quicker. Please note that Ivorey
has zero control over this process and we cannot do anything to speed it up.
If denied, you'll need to address any errors and resubmit. Review the rejection reason carefully and refer back to the How to Avoid Rejection section above to identify what needs to be corrected before resubmitting.
Once your Brand registration is successfully approved as part of the A2P 10DLC setup, the next essential step is to register a Campaign associated with that Brand. This step is mandatory to begin sending A2P messages through 10DLC phone numbers. It’s very important to note that Campaign registration is not triggered automatically once your Brand gets approved.
You will need to manually submit the Campaign registration yourself, after Brand approval. Until this is done, your A2P 10DLC setup remains incomplete, which means you will not be able to send compliant SMS messages through your 10DLC numbers.
After receiving confirmation that your Brand is approved, you must complete your Campaign registration.
From the Ivorey
main menu, go to [Settings] > [Phone Services] > [Trust Center] > and under A2P Messaging, click the [Create Campaign] button
Follow the prompts to complete the Campaign registration form
Await Campaign approval before using your number for A2P messaging
Sole Proprietor is for individuals without an EIN. Standard Brand is for registered U.S. businesses with an EIN.
Likely reasons for an A2P rejection include EIN mismatch, invalid website, or use of a PO Box address. Ensure the legal business name and EIN number match exactly to what’s shown on the CP 575 form. Do not use the business name found on W2 or W9 forms, as they may differ. If the business name spans multiple lines on your CP 575/147c letter, you must enter all lines above the address line during registration.
Example:
ABC Holding Group Inc.
Division of Regional Services
123 Main Street
New York, NY 10001
The legal name to enter would be: ABC Holding Group Inc. Division of Regional Services
Yes, after your brand and campaign are approved, you can add new numbers which will be automatically registered under the same campaign. There is no resubmission is needed, but it may take several days for registration to complete.
If your A2P 10DLC registration fails multiple times, it may reach the maximum retry limit. When this happens, the A2P section in the Trust Centre appears greyed out and the registration wizard is no longer available.
Once the retry limit is reached, the registration can’t be resubmitted from your end, even if you’re prompted to do so. An internal reset is required before you can return to the Trust Centre and submit the registration again. Please reach out to Support via the live chat widget to request a reset.
Carriers have very strict requirements for how you collect phone numbers. Your registration is likely being rejected because the form is "hidden" (for example, if a user has to pick a calendar date before seeing the form) or because it's missing mandatory legal language. To get approved, ensure your campaign link goes directly to a page where the form is visible immediately, include an unchecked consent box that mentions your business name, and provide clear links to your Privacy Policy and Terms of Service right next to the submit button.
