CTIA Short Code Monitoring Handbook

COMPLIANCE FRAMEWORK

This section offers direction regarding compliance of short code programs, including guidelines and requirements. Nonetheless, following this handbook is no guarantee that a short code program is compliant. Short code programs might also need to comply with individual carrier requirements.

UNIVERSAL COMPLIANCE PRINCIPLES

CTIA requires all short code programs to comply with a basic code of conduct that promotes the best possible user experience. As new uses for short codes emerge, the guiding principles in section A.1 should be considered when defining applicable rules. Short code programs that comply technically with the letter of a specific rule but violate the letter or spirit these principles might be subject to enforcement action.

 

A.1  GUIDING PRINCIPLES

Four principles provide the baseline for all requirements listed below:

  1. Display clear calls-to-action. All programs must display a clear call-to-action. Customers must be made aware of what exactly they are signing up to receive.
  2. Offer clear opt-in mechanisms. Customers must consent clearly to opt into all recurring-messages programs. Requiring a customer to enter a mobile phone number does not constitute a compliant opt-in. Instead, customers must understand they will receive messages and consent to receive them.
  3. Send opt-in confirmation messages. A confirmation message must be sent to customers always. For recurring-messages programs, confirmation messages must include clear opt-out instructions.
  4. Acknowledge opt-out requests. Short code service providers must acknowledge and act on all opt-out requests. Monitoring procedures confirm successful opt-out.

 

A.2  CHOICE AND CONSENT

Short code programs are expected to deliver sufficient value so consumers elect to participate with full transparency into the delivery conditions.

 

A.2.01  UNSOLICITED MESSAGES

Unsolicited messages may not be transmitted using short codes. Unsolicited messages are defined as follows:

  • Messages delivered without prior express consent from the user or account holder, and
  • Messages sent after a user has opted out. Sending the user a single opt-out message acknowledging the opt-out request is the only exception to this rule.

 

A.2.02  MARKETING CONTEXT

No component of program advertising or messaging may be deceptive about the underlying program’s functionality, features, or content. All disclosures present in pre-purchase calls-to-action, advertisements, terms and conditions, and messages must remain clear and consistent throughout the user experience.

 

A.2.03  OPT-IN

Messages must be delivered to a consumer’s mobile device only after the user has opted in to receive them. A user might indicate interest in a program in several ways. For example, a user might

  • Enter a phone number online,
  • Click a button on a mobile webpage,
  • Send an MO message containing an advertising keyword,
  • Sign up at a point-of-sale location, or
  • Opt in over the phone using interactive voice response (IVR) technology.

Calls-to-action must be clear and accurate; consent must not be obtained through deceptive means. For example, opt-in details cannot be displayed obscurely in terms and conditions related to other services. Enrolling a user in multiple short code programs based on a single opt-in is prohibited, even when all programs operate on the same short code.

Recurring-messages short code programs should send a single opt-in confirmation message that displays information verifying the customer's enrollment in the identified program. The opt-in confirmation message must be delivered immediately after the customer opts into the program. Additionally, opt-in messages must contain the program (brand) name or product description, customer care contact information, opt-out instructions, product quantity or recurring-messages program disclosure, and the “ message and data rates may apply” disclosure.

The opt-in for all short code programs must comply with all legal and regulatory requirements, including the Telephone Consumer Protection Act, 47 U.S.C. § 227, and the Federal Communication Commission’s rules under 47 C.F.R. § 64.1200. For example, the express written consent obtained for any program that is “telemarketing” [as defined by 47 C.F.R. § 64.1200(f)(14)] must, unless exempt from the requirement, include the elements of “prior express written consent” set forth in 47 C.F.R. § 64.1200(f)(8). That rule requires a clear and conspicuous disclosure informing the user that:

  • By opting in, the user authorizes the seller to deliver or cause to be delivered to the user marketing messages using an automatic telephone dialing system; and
  • The user is not required to opt in (directly or indirectly) as a condition of purchasing any property, goods, or services.

Legacy double opt-in (i.e., mobile device confirmation) methods remain acceptable options to obtain express consumer consent.

 

A.2.04  OPT-OUT

Functioning opt-out mechanisms are crucial for all text messaging programs. Programs must always acknowledge and respect customers’ requests to opt out of programs. However, depending on the use case, some short code programs are not required to advertise opt-out instructions. Short code programs must respond to, at a minimum, the universal keywords STOP, END, CANCEL, UNSUBSCRIBE, and QUIT by sending an opt-out message and, if the user is subscribed, by opting the user out of the program. Subsequent text, punctuation, capitalization, or some combination thereof must not interfere with opt-out keyword functionality.

Recurring-messages programs must also display opt-out instructions at program opt-in and at regular intervals in content or service messages, at least once per month. Opt-out information must be displayed in bold type on the advertisement. A program may deliver one final message to confirm a user has opted out successfully, but no additional messages may be sent after the user indicates a desire to cancel a short code program.

 

A.3  CUSTOMER CARE

Customer care contact information must be clear and readily available to help users understand program details as well as their status with the program. Customer care information should result in users’ receiving help. Programs must always respond to customer care requests, regardless of whether the requestor is subscribed to the program. At a minimum, the HELP keyword must return the program name and further information about how to contact service providers. Short code programs should promote customer care contact instructions at program opt-in and at regular intervals in content or service messages, at least once per month.

 

A.4  PROGRAM CONTENT

All content associated with short code programs must promote a positive user experience. Carriers regulate certain types of content, including those listed in this section.

 

A.4.01  UNAPPROVED OR ILLICIT CONTENT

No programs associated with carrier brands or operating on the carrier networks may promote unapproved or illicit content, including the following:

  • Depictions or endorsements of violence,
  • Adult or otherwise inappropriate content,
  • Profanity or hate speech, and
  • Endorsement of illegal or illicit drugs.

Programs must operate according to all applicable federal and state laws and regulations. All content must be appropriate for the intended audience. Additional legal and ethical obligations apply when marketing to children under age 13, and such programs might be subject to additional review by carriers.

 

A.4.02  CONTROLLED SUBSTANCES

Promotions of controlled substances might be subject to additional review by carriers. Service providers must receive explicit carrier approval before launching these program types. Marketing of hard alcohol and tobacco brands must either include robust age verification (e.g., electronic confirmation of age and identity) at opt-in or restrict promotions to age-verified locations (e.g., points of sales in bars). Mobile programs must not promote the use of controlled substances directly. Reference to the abuse of controlled substances is prohibited.

 

A.4.03  SWEEPSTAKES AND CONTESTS

Sweepstakes and contests might be subject to additional review by carriers. Service providers must receive explicit approval from carriers before launching these program types. All sweepstakes must support a no-cost entry method. Service providers operating sweepstakes should seek legal guidance.

 

A.4.04  CONTENT DELIVERY

Users should be informed of the next steps to download and store new content immediately after opt-in. Content must be delivered correctly and must function as advertised.

 

A.5  PRIVACY POLICY AND TERMS AND CONDITIONS

Service providers are responsible for protecting the privacy of user information and must comply with applicable privacy law. Service providers should maintain a privacy policy for all programs and make it accessible from the initial call-to-action. When a privacy policy link is displayed, it should be labeled clearly.

Use cases might require different disclosures in the full terms and conditions. In all cases, terms and conditions and privacy policy disclosures must provide up-to-date, accurate information about program details and functionality.

 

A.6  PROGRAM NAME AND PRODUCT DESCRIPTION

Consistent program names and product descriptions in advertisements and messages help consumers connect all parts of the short code experience. All short code programs are required to disclose program names, product description, or both in service messages, on the call-to-action, and in the terms and conditions. The program name is the sponsor of the short code program, often the brand name or company name associated with the short code. The product description describes the product advertised by the program.

 

A.7  PROGRAM RECORDS AND FUNCTIONALITY

Service providers assume responsibility for maintaining accurate records in carrier systems and the Common Short Code Administration (CSCA) registry. Service providers wishing to modify a program must submit changes to the carriers for review and must update relevant carrier records. Programs promoted in the market must match the programs approved.

 

A.7.01  CUSTOMER RECORDS

All opt-in and opt-out requests should be retained from the time a user initiates opt-in until a minimum of six months after the user has opted out of a program. Service providers assume responsibility for managing information about deactivated and recycled mobile phone numbers and must process this information within three business days of receipt. After porting a mobile phone number between carriers, the user must opt in again to desired programs.

Service providers must track opt-in information by individual user. Selling mobile opt-in lists is prohibited.

 

A.7.02  MO MESSAGE PROCESSING

All mandatory keywords must be processed correctly, regardless of MO message format (e.g., keywords must function whether sent by MMS or SMS). Service providers must scan MO message logs regularly to identify opt- out attempts and must terminate those subscriptions, regardless of whether the subscribers used the correct opt- out keywords or methods.

 

USE CASES

Because short code programs vary greatly, depending on their intended purpose, Handbook v1.5.0 was designed with different use cases in mind. All short code programs based on the displayed use cases must comply with the Universal Compliance Principles in addition to the specific guidelines described in this section.

 

A.8  SINGLE-MESSAGE PROGRAMS

Single-message programs, or “one-off” programs, deliver a one-time message in response to user opt-in requests. Examples of single-message programs include but are not limited to the following:

  • Informational alert,
  • Purchase receipt,
  • Delivery notification, and
  • Two-factor authentication.

  • Content or informational alert subscriptions (e.g., horoscopes, news, weather),
  • Flight status notifications (multiple messages), and
  • Marketing and loyalty promotions.

 

Exhibit 2: RECURRING-MESSAGES PROGRAM USE CASE QUICK REFERENCE GUIDE

A.10  MACHINE-TO-MACHINE PROGRAMS

Machine-to-machine (M2M) short code programs, which should never interact with consumers, only need keep an updated program brief on file with the CSCA and the carriers.

 

A.11  PREMIUM RATE POLITICAL DONATION PROGRAMS

Premium rate short code programs that solicit political donations are subject to additional regulations, available at http://www.ctia.org/policy-initiatives/voluntary-guidelines/federal-political-campaign-contributions-wireless-carrier-bill. Premium political donation programs also must conform to the premium SMS guidelines and audit standards in the Handbook v1.3.

 

A.12  PREMIUM RATE CHARITABLE DONATION PROGRAMS

Premium rate short code programs that solicit charitable donations are subject to additional regulations, available at http://www.ctia.org/policy-initiatives/voluntary-guidelines/mobile-giving-via-wireless-carrier%27s-bill. In addition, premium charitable donation programs must to conform to the premium SMS guidelines and audit standards in Handbook v1.3.

 

A.13  FREE-TO-END-USER PROGRAMS

FTEU programs are subject to almost all of the same requirements as SMS short code programs. FTEU programs must display a clear call-to-action, capture consumers’ affirmative opt-in, send an opt-in confirmation message, and abide by customers’ requests to opt-out. However, all FTEU programs are exempt from displaying “message and data rates may apply” in advertisements, terms and conditions, and messages.

 

A.14  MMS PROGRAMS

MMS programs are subject to the same requirements per use case as SMS short code programs. All mandatory keywords must be processed correctly, regardless of MO format (e.g., keywords must function whether sent by MMS or SMS). Service providers must scan MO logs regularly to identify opt-out attempts and must terminate associated subscriptions, regardless of whether the subscribers used the correct opt-out keywords or methods.

Additional best practices specific to MMS will be released in an upcoming version of the Handbook.

 

CARRIER ONBOARDING

CTIA is most concerned with short code programs as they interact with consumers through advertising and service messaging. However, several facets of SMS programs happen behind the scenes. Recommended best practices for onboarding new programs follow.

Carriers may maintain individual playbooks tailored to their customers’ needs and must sometimes respond to emerging risks that fall outside the Handbook. Refer to carriers’ playbooks for onboarding information regarding

  • Program certification and migration processes,
  • Program brief details,
  • Advertising of controlled substances,
  • Sweepstakes approval processes, and
  • Marketing to children.

IN-MARKET MONITORING GUIDE

In this section, in-market monitoring, including details about audit notices, communication, retests, and appeals, is explained.

COMPLIANCE AUDITS

The CTIA Compliance Assurance Solution employs data gathered via in-market monitoring. When programs are deployed in market, the live programs are captured and audited. This method is more effective than program brief review or routine keyword testing because compliance audits reflect the user experience that actual consumers encounter when they interact with short code programs in market.

CTIA issues compliance audits weekly for standard rate short codes leased with the CSCA. Compliance audits performed by CTIA are available to all major U.S. carriers, and CTIA compliance metrics can be incorporated into individual carrier compliance policies.

 

A.15 AUDIT NOTICES

CTIA distributes Audit Notices each week. Each audit notice displays a unique audit number, short code, service provider, aggregator or aggregators, notice date, and cure date at the top. Individual violations are classified as Severity 0, Severity 1, or Severity 2, based on their potential for consumer harm, with Severity 0 representing the most extreme violations. Violations are based on the compliance guidelines outlined in the Compliance Framework section of the Handbook. Taking the severity level of the gravest violation cited, a failed audit must be resolved in the appropriate timeframe (i.e., before or on the cure date).

 

A.16 SCHEDULE

CTIA compiles and generates audit notices each Monday for audits performed the previous week, and audits are published Tuesday at 2:00 A.M. EST. Although audits might be available for review earlier, the official notice date from which the cure date is calculated is 12:00 P.M. EST each Tuesday.

 

A.17 SEVERITY LEVELS

All audit notices are assigned severity levels based on the extent to which the associated findings might harm consumers. Cure dates and penalties vary based on severity, as detailed in Exhibit 3.

 

EXHIBIT 3: AUDIT NOTICE SEVERITIES DESCRIPTION

    Definition  Cure Date  Penalties
Severity 0 Extreme consumer harm Immediate

CTIA: Immediate registry suspension harm

Carriers: Vary by case; immediate suspension or termination possible

Severity 1 Serious consumer 5 business days

CTIA: Unresolved audits; possible registry harm suspension

Carriers: Vary by case

Severity 2 Moderate Consumer Harm 5 business days

CTIA: Vary by case consumer harm

Carriers: Vary by case

 

A.18 CTIA COMPLIANCE CARE TEAM COMMUNICATION

On receiving an audit notice, service providers may communicate with the CTIA compliance care team by leaving a comment on the audit notice or contacting us.support@wmcglobal.com. The CTIA Compliance Care Team (Care Team) responds promptly to all messages. Although Care Team specialists are unable to preapprove compliant designs, they assist service providers as much as possible with understanding how to resolve violations and close their audits.

 

A.19 RETESTS

Within the prescribed period following issuance of an audit notice, the responsible aggregator or service provider must confirm on the audit notice that it has made changes to or has removed from market the offending advertisement or message flow. Should the CTIA Compliance Care Team fail to receive confirmation or should the service provider fail to take the actions required, the short code is subject to further action.

In the case of TV and print advertisements with longer run cycles, aggregators and service providers may submit a retest request for a rerelease date. Retest requests must be made in good faith, with a clear explanation of the changes implemented. Audits at this status are categorized as Pending Retest.

 

A.20 APPEALS

Aggregators and service providers that believe they have a valid claim may challenge an audit by contacting us.support@wmcglobal.com before the cure date noted on the audit notice. The email message should explain why the service provider deems the audit incorrect. Appeals must pertain to the application of violations cited on the specific audit in question.

 

A.21 SUSPECTED PROGRAM NONCOMPLIANCE

To report possible noncompliant programs that you have observed in market, you may contact the CTIA Compliance Care Team at us.support@wmcglobal.com. Be sure to include the location of the call-to-action and the short code in your email message. Should CTIA decide to escalate the matter, the reporter’s information would be kept confidential.


AUDIT STANDARDS GUIDE

The following pages display tables of audit standards by use case. Advertising audit standards apply to all advertisements hosting calls-to-action for short code programs; message flow audit standards apply to required service messages. Message categories for which specific standards apply are marked with an “x” in the tables. Refer to the glossary below for help with unfamiliar terms.

Opt-In Confirmation Short code programs should send a single opt-in confirmation message displaying information verifying the customer’s enrollment in the identified program and describing how to opt out. The opt-in confirmation message must be delivered immediately after the customer opts into the short code program. Additionally, opt-in messages must contain the program (brand) name or product description, customer care contact information, product quantity or recurring-messages program disclosure, and the “message and data rates may apply” disclosure.
 HELP Message service providers send after customers text the HELP keyword. Short codes should reply with additional contact information to customer requests for help.
 Opt-Out Message service providers send after customers text the STOP keyword. The opt-out message confirms that the customer has been opted out of the program.
 Violation Specific breach of the Universal Compliance Principles. Auditors check program advertisements and service messages against lists of violations to identify noncompliance.
 Severity Number representing the customer impact associated with a violation. Severity 0 violations impact customers most. Severity 2 violations are least customer impacting.
 Action Required  Action or actions the responsible service provider must take to correct the associated violation.

AUDIT STANDARDS

The audit standards listed below distill the principles listed in the narrative portion of the Handbook into test scripts for monitoring. Advertising audit standards apply to media displaying short code calls-to-action. Message flow audit standards apply to required service messages.
