Alcohol

Last updated: April 2025

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 channelAllowed 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 a 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.

Authentication (2FA/OTP/MFA)

Last updated: April 2025

Authentication programs, such as two-factor authentication, one time passcode, and multi-factor authentication are used over SMS to assist in the authentication of a user account for security purposes.

Messaging channelAllowed requirements
All senders

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
  • HELP and STOP are still required to function on a 2FA/MFA/OTP program
  • 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.

Sources to reference
  • CTIA Short Code Monitoring Handbook Exhibit 3.9.1 Single Message Programs
  • 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.

The compliance guidelines for cannabis messaging are the same across all sender types in the US.

  • As a standard, any promotion of cannabis is strictly prohibited
  • Some use cases related to cannabis advocacy may be approved on a case-by-case basis

Cryptocurrency

Last updated: April 2025

Messaging programs related to cryptocurrency.

Messaging channelAllowed requirements
All senders

  • Certain use cases that support Cryptocurrency brands may be considered on a case-by-case basis (2FA, account notifications)
  • No messaging related to the marketing promotion or transactions is permitted
Sources to reference

This guidance comes directly from feedback from Tier 1 operators in the US and, while not documented, is known to be disallowed based on prior RFIs, rejections, and conversations. This stems from the lack of security around such messaging and the high probability of fraud.

Last updated: April 2025

Messaging channelAllowed requirements

  • 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.

Marketing (promotional marketing)

Last updated: April 2025

Any communication that includes marketing and/or promotional content. Promotional messaging is when a message contains a sales or marketing promotion.

Messaging channelAllowed 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.

  • This guidance comes directly from 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 ensuring promotional marketing messages have proper consent. It is also a poor customer experience and leads to high volumes of SPAM for customers to have marketing messages combined with other services like delivery notifications, account alerts, and so on.

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.

  1. Verify with our Compliance team that your current campaign and brand are eligible for a number pool upgrade. Submit the completed 10DLC Number Pooling Request Form (opens in a new tab) to sms_compliance_operations@infobip.com.
  2. Compliance approval: The Compliance team reviews your request and confirms whether the campaign is suitable for a number pool upgrade.
  3. Developer integration: Additional development work is necessary to implement number pooling for your campaign.
  4. 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.

Pharmaceutical marketing

Last updated: April 2025

Marketing messages related to medications that require a prescription. This is not related to pharmacy notifications for refill reminders, pick up details, and so on.

Messaging channelAllowed requirements
All senders

The compliance guidelines for pharmaceutical programs are the same across all sender types in the US.

  • Should not be directly promotional
  • Preference would be to not directly name the medication unless the messages are targeted directly to those with confirmed prescriptions
  • Example: 15% off weight loss prescriptions versus 15% off compound semaglutide
  • Example: Come in for our latest medspa injectable versus Come in and get a botox injection

This guidance comes directly from 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 ensuring that content is legal in all 50 states and the marketing of medications is not sent to those without a prescription.

Viral messaging (short code only)

Last updated: April 2025

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 channelAllowed 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.
