Messaging related to alcohol. These programs will be reviewed on a case-by-case basis and are not guaranteed for approval by the US operators on any sender.
Messaging channel
Allowed requirements
All senders
The compliance guidelines for alcohol messaging are the same across all sender types in the US.
As a standard, direct promotion of the sale or consumption of alcohol is not typically allowed
Example: "Use code DRINK15% for 15% off our newest vodka"
Indirect promotion of these items is approved on a case-by-case basis:
Items like cart reminders, shipping notifications, and exclusive coupon codes for the website
Example: "Brand: Hey, did you leave something in your cart? Complete your checkout now by clicking www.website.com(opens in new tab)"
"Brand: Hey, we’ve got an exclusive discount just for you, check out our new products for a discount"
A robust age gate is required, with either:
A user reply over MT with their birthdate (MM/DD/YYYY) or a user to enter their birthdate MM/DD/YYYY on a web form field
Asking a user to "Reply YES/AGREE" to confirm they are over a certain age is not considered to be robust age verification
Having a web form that asks if a user is "over 18/21 YES/NO" is not considered to be robust age verification
For brands that do not directly sell alcohol but sell items related to alcohol (brew kits, wine accessories), or locations that primarily sell alcohol but offer other services (vineyards, breweries with restaurants) while an age gate may not be required if the main content is not legally age restricted it is recommended for campaign registration. Or it is recommended to add a disclaimer in the campaign summary that the campaign will only be to send messaging related to other products or services and no alcohol or age restricted content will be sent.

The compliance guidelines relating to authentication are the same across all senders in the US.
Opt-in requirements for this use case still exist and should follow CTIA Messaging Principles and Best Practices

2FA is not required to be received using SMS and there should be an alternative means to validate accounts for users that do not wish to use SMS, for example, email, verbal, and so on
In many cases, multiple brands may use a single short code for 2FA, as long as all messaging is controlled by the direct owner of the short code and all messaging is templated for 2FA.
RCS
Follows all other US sender types

The requirement for an alternative method besides SMS comes directly from one of the Tier 1 operators in the US and, while not documented, is known to be required based on prior RFIs, rejections, and conversations. This stems from CTIA requirements of Choice and Consent, and if 2FA over SMS is required, there is no choice to consent.

Messaging programs that support, remind, suggest, request, or advertise "giving" or "donation" to a brand.
Messaging channel
Allowed requirements
Short code
Infobip can manage the messaging but cannot handle mobile billing. The customer must have an agreement with a mobile billing provider. If the donation aspect of the campaign does not occur using the short code (for example, donation occurs through a web form using a URL), the following must be adhered to:
Be qualified as tax-exempt under Section 501(c)(3) of the Internal Revenue Code
Be accredited by at least one arm's-length, disinterested nonprofit accreditation organization (such as Better Business Bureau Wise Giving Alliance, Charity Navigator)
Receive separate opt-ins for informational and solicitation messages if both types of messages are provided under the same short code
Do not use the message program for lotteries, sweepstakes, raffles, or recurring donations
Ensure no entities involved in the donation campaign, aside from the charitable organization itself, use any part of the mobile subscriber data collected
For charitable donation programs outside of direct-carrier billing, the dedicated application address must be leased or owned by the charitable organization
Charitable donation programs supported by a DCA must provide the following information to prove tax-exempt status under Section 501(c)(3) of the Internal Revenue Code:
Charitable organizations accepting donations must maintain 501(c)(3) tax-exempt status and should not fall under the classification of 501(c)(4) entities. These organizations must avoid displaying political bias on their websites or in their messaging. If political affiliations or leanings are present, they must adhere to the political messaging requirements (see 'Political Campaigns' section).

Allowed requirements
All senders
The compliance guidelines for marketing programs are the same across all sender types in the US.
Must select marketing use case
Prior express written consent is required
Adding a call-to-action like a coupon code to an informational text may place it in the promotional category. Before a business sends promotional messages, the consumer must agree in writing to receive promotional texts. Businesses that already ask consumers to sign forms or submit contact information can add a field to capture consent.
In the event that a campaign is submitted for multiple use cases, one of which includes promotional marketing, there must be a separate opt-in mechanism for marketing or, marketing must be expressly noted in the verbiage of the call-to-action. For example, by providing your number and consenting to YourBrand SMS in the checkout, you agree to receive recurring text notifications (for your order, including abandoned checkout reminders), text marketing offers, and transactional texts, including requests for reviews from us. Msg and data rates may apply. Reply HELP for help, STOP to opt out. View Terms and Privacy.

A pool of numbers, often identified by a SUBID, assigned to a single campaign where more than 49 numbers are needed.
Number pooling is currently only available on 10DLC.
NET NEW for external customers (CSPs)
When creating a campaign:
Select the Number Pool attribute under Campaign Attributes.
In the Campaign Description section under Campaign Details, provide the following information:
Clearly state: THIS SUBMISSION IS FOR A NUMBER POOL USE-CASE
A clear explanation of the number pool intended use
Number pool upgrade for external customers
This process can be used if a customer has an already live and compliant campaign, but the customer has decided that a number pool use case is a better option:
Compliance approval: The Compliance team reviews your request and confirms whether the campaign is suitable for a number pool upgrade.
Developer integration: Additional development work is necessary to implement number pooling for your campaign.
Number pool activation: Once the development work is complete, the Compliance team confirms that the number pool has been successfully added to your campaign. At this point, you can begin by adding additional sender numbers.
NET NEW for internal customers
When creating a new campaign:
Select the Number Pool attribute under Campaign Attributes.
In the Campaign Summary section under Campaign Information.
Clearly state: THIS SUBMISSION IS FOR A NUMBER POOL USE-CASE
Provide a concise explanation of how the number pool will be used, for example: "Each employee will be assigned a unique number for direct communication with customers"
Number pool upgrade for internal customers

Currently, Infobip does not support P2P in the US. This applies to all sender types, short code, 10DLC, and Toll-Free Number. As these channels are to support A2P messaging, P2P use cases will not be considered. P2P support is not currently planned for support.
There are rare circumstances where other providers are able to provide P2P exceptions where a P2P use case can be approved to run on an A2P 10DLC. Infobip does not currently support this service.
Messaging channel
Allowed requirements
P2P
Means Person-to-Person messaging. It is a decentralized communication model where devices (peers) communicate directly with each other, without relying on a central server.
Some examples of P2P include:
- Number Masking applications that allow individuals to purchase, or be assigned random 10DLC numbers which allow them to text over SMS without use of their personal mobile device
- Manual replies to business inquiries from a phone
- Customer texting into a small business owners personal phone
The main features are
- No central server needed
- Direct device-to-device connection
Typically, P2P is used for consumer-level applications, small-scale communication, or systems needing low infrastructure.
Compliance considerations: Does not typically follow 10DLC registration and compliance guidelines. Subject to high filtering, and low volume
Infobip does support UCaaS, which may, in some circumstances, appear to be person-to-person messaging.
All UCaaS programs will be considered on a case-by-case basis, and any programs submitted that fall into the P2P category are subject to rejection.
UCaaS
Defined by TCR as UCaaS companies that provide cloud-delivered communication services for businesses. Each number assigned to a UCaaS campaign is typically assigned to a different employee of that business, and the use cases are varied. This use case is not for any API/automated-driven communication.
Some examples of UCaaS include:
- A business assigns a single phone number to each employee to communicate using SMS with other employees
- Conversion of intra-office messages via Teams to SMS to individually assigned phone numbers
- Two-way support conversations
The main features are
- Centralized service
- Managed infrastructure
- Fully-managed communication solution
- Messages are sent from applications, not personal phones
Compliance considerations: Must follow 10DLC registration and compliance guidelines – including opt-in and support of HELP and STOP.
Infobip does support UCaaS, which may, in some circumstances, appear to be person-to-person messaging.

Stock alerts are generally considered disallowed content falling under the High Risk Financial Classification. However, some content types are considered allowed within restrictions. Messages which attempt to market specific stocks or products will likely be rejected. Avoid investment advice programs or lead generation and affiliate marketing programs.
The following are examples of disallowed content:
"Sign up here to start trading — limited spots!"
"Join our partners for exclusive stock picks"
"We'll share your info with our investing partners"
Messaging channel
Allowed requirements
All senders

This includes articles, blog posts, newsletters, explainers, and market education where the primary purpose is learning, not trading

Viral messaging is a process in which a consumer receives a message, identifies one or more other consumers as likely to be interested in receiving a similar message, and then initiates a process for the other consumers to receive the message. For example, consumer A may input consumer B's phone number into an app to send a message to consumer B through short code.
Messaging channel
Allowed requirements
Short code
A message sender may send viral messaging through short code. The mechanism for a message sender to send viral messaging requires a consumer to:
Verify that the consumer has obtained each message recipient's consent to send the message.
Individually identify and select each message recipient.
Confirm that each message will be sent on the consumer's behalf.
Additionally, any viral messaging must state why the recipient has received the message, including identifying the consumer sending the message and the purpose of the message.
Message senders must honor all opt-out requests from message recipients by opting the message recipient out of all messages sent through the viral messaging application, software, or program. Additionally, consumers sending viral messaging may not receive anything of value for using the viral messaging application, software, or program. To be consistent with the CTIA Short Code Monitoring Handbook's goals, these requirements honor consumer choice, help prevent abuse of messaging platforms, and facilitate transparency.

As Google only allows four use case label types for RCS, the following table maps those labels to their definitions and examples.
Use case label
Definition and examples
One-Time Password (OTP)
OTP messages are used strictly for authentication, identity verification, or secure transaction confirmation. These messages are short-lived, time-sensitive, and may not include any promotional content.
Examples:
Account login verification: "Your verification code is 482917. It expires in 10 minutes."
Password reset: "Reset code: 903221. Enter this to change your password."
High-risk activity confirmation: "To confirm your wire transfer of $1,200, enter code 551004."
Two-step authentication: "Use code 774022 to verify your identity for account access."
Compliance notes:
OTP messages cannot contain marketing or promotional language.
Content must relate only to authentication or security.
Transactional messaging
Transactional messages provide information related to a customer's existing relationship, purchase, service, or account activity. These messages are informational only.
Examples:
Purchase confirmation: "Thank you for your order! Your receipt #88421 has been emailed to you."
Delivery update: "Your package is out for delivery and will arrive today by 6 PM."
Appointment reminder: "Reminder: Your appointment with Dr. Lee is scheduled for March 20 at 2:00 PM."
Suspicious login alert: "We detected a login attempt from a new device. If this wasn't you, please reset your password."
Billing update: "Your payment of $45.23 was received. Thank you!"
Compliance notes:
Must be directly tied to a customer's existing service or action.
May not include promotional or marketing content.
Promotional messaging
Promotional messages are intended to market, advertise, or increase engagement. These include offers, discounts, product launches, and marketing campaigns.
Examples:
Limited-time offer: "Flash Sale! Take 25% off all items today only."
Product announcement: "Our new spring collection is here! Explore the latest arrivals."
Loyalty rewards: "Enjoy a 15% loyalty discount on your next purchase."
Event invitation: "Join us this weekend for our in-store customer appreciation event."
Compliance notes:
Requires express consent from the customer.
Must include proper opt-in disclosures and STOP instructions.
Multi-use messaging (mixed campaigns)
Multi-use messaging includes a combination of transactional and promotional content within the same customer journey. This is acceptable only when proper promotional-level consent is obtained.
Examples:
Account update + offer: "Your subscription renews on April 1. Upgrade now and save 10% on Premium."
Delivery confirmation + recommendation: "Your order has been delivered. Get 15% off your next purchase with code WELCOME15."
Appointment reminder + promotion: "Your massage appointment is tomorrow at 3 PM. Add another service today and receive 20% off."
Usage notification + upgrade offer: "You've used 90% of your data. Add 5GB for just $5."
Compliance notes:
