Message Content Assistance

The CTIA and U.S. wireless carriers have created these content requirements for business-to-consumer messaging so that their customers, the mobile users, have a consistent user experience with a clear understanding of all aspects of the service to which they have subscribed. A consistent experience and clear support information reduces the number of customer service calls and complaints to wireless carriers. The message components described in the following articles are required for both recurring and one-time message programs.*

Short Code Message Content

All components shown in the templates within the sections below are necessary for full compliance. The following bulleted list is a key which will assist you in reading the template and the example shown below.

  • Items in [brackets] are those which will be replaced based on your specific use-case, as shown in the example.
  • Items in “normal” font outside of the brackets should appear in your texts exactly as they appear in the template.
  • The Additional Outbound Message is a second outbound message sent in a one-time program if all desired time-of-opt-in outbound message content cannot fit within the 160-character limits of the Opt-in message alongside all of the required components depicted below. The Additional outbound message will be charged your outbound message rate.

Please note that compliance requirements have recently changed - while the Sponsor & Program Name is still required within the body of the message, it is no longer strictly required at the beginning of the message followed by a colon (though we do recommend this format as best-practice and for saving character space).

One-Time Message Flow

Also referred to as a “query,” “transactional” or “non-recurring” service, the one-time message program is one in which the end-user texts in a keyword or submits a web prompt to receive the desired response instantly. The end-user will not receive any future messages from the service unless they text in or otherwise engage the service again.

OTP/2FA Message Flow

For One-Time Password or Two-Factor Authentication campaigns, the end-user has most likely signed up for a web service. In order to log into this web service or–for example–change a forgotten password, the site may forward them a one-time password that they may use to log in and change their password information.

Please note that while it may seem silly to provide HELP and STOP functionality for what is not only a one-time message but a flow that is not in and of itself a mobile-based campaign, it is a carrier-best-practice requirement that these keywords be understood by all end-users and be live and available with appropriate and applicable responses.

Recurring Message Flow

End-users who opt into a recurring or “subscription-based” mobile program elect to receive messages at regular or event-triggered intervals over a given or indefinite period of time. Unlike one-time message programs, these programs require a Subscription Renewal Reminder Outbound which you will see in the template.

Short Code Campaign Requirements

Initial / Opt-In Message

Acceptable opt-in methods for a U.S. Short Code Campaign are:

  • Handset
  • Web Form
  • Mobile App
  • IVR

Initial / Opt-in MT

  • Sponsor/Program Name
  • Product Description
  • Message Frequency/“Recurring” Statement*
  • Msg&Data Disclaimer
  • Help Instructions
  • Stop Instructions
  • Customer Support Info

*If your program is recurring, you are required to state as much explicitly within your Opt-In MT.

Double Opt-In Webpage & PIN or “Reply Yes” MT

Please note that while double opt-ins are no longer required for U.S. web-based opt-in mechanisms, they are still required in Canada.

Double opt-ins are only required for standard-rate campaigns when opting in via the web. When the end-user opts in online, it will trigger a handset verification message which will be sent to the user’s device for confirmation (see Double Opt-In Confirmation MT).

  • Sponsor/Program Name
  • Product Description
  • Message Frequency
  • Msg&Data Disclaimer
  • Help Instructions
  • Action Request*

*An “Action Request” can take the form of a pin code or the request of a response (reply “YES” to confirm).

Double Opt-In Confirmation MT

  • Sponsor/Program Name
  • Message Frequency
  • Msg&Data Disclaimer
  • Help Instructions

Primary Content Message

Contains a program’s primary content such as account alerts, promotions, sports updates, information about the subject, etc.

In a Recurring Message Flow the Primary Content Message may appear at any time, including immediately following the Opt-in Message, provided that it does not exceed the message frequency.

It requires only:

  • Sponsor/Program Name
  • Msg&Data Disclaimer

In a One Time Message Flow the Primary Content Message:

  • Is an optional 2nd message that immediately follows the first message.
  • May use all 160 characters/spaces freely*

A one-time message program’s application should place a short delay on the Primary Content Message so that it is not delivered to the end-user’s mobile device prior to the first message containing the required compliance language. Messages sent out of order will confuse the end-user and risk audit failure through major carriers who require that a message containing all compliant content be delivered to the handset first.

*The first of the two one-time messages must contain all compliant language required of an “initial” (opt-in) message.

Help/“Customer Care” Message

End-users must always be able to send “HELP” and receive what is referred to as “customer care” information. Furthermore, short codes are now required to send “Customer Care” messages at regular intervals (once a month being the minimum) with “customer care” contact information included. We recommend just using your HELP message for this, and sending its contents out once monthly.

Help/“Customer Care” MT

  • Sponsor/Program Name
  • Message Frequency
  • Msg&Data Disclaimer
  • Stop Instructions
  • Customer Support Info

STOP Message

Stop MT

  • Sponsor/Program Name
  • “You have been unsubscribed”
  • “You will no longer receive messages”
  • Customer Support Info

Existing Program Code Change Notification Message

If you are switching the code you use for your campaign, whether it is from long code to short code, or one short code to another, you must notify existing subscribers of the change.

This notice must:

  • Come from the code to which the end-user originally opted in
  • Include opt-out instructions
  • Be the last message sent to the end-user from the program on the old short code

Code Change Notification MT:

Sponsor & Program Name: Future content will be sent from #####. Reply STOP to cancel.

Short Code Verbiage

Now that you’ve seen the components required in your message flow(s), you may be looking to understand better the logic behind them and the acceptable incarnations of each piece in its spelling and punctuation.

This is the name of the company or brand providing the mobile service. It should be the first word in each SMS.

Note: Sponsor and Program Name must lead every message in the entire program

*NuTech Latest: Get the top tech stories of the week! 1msg/week. Msg&DataRatesMayAply. Reply HELP for help, STOP to cancel. 18001234567.*

In the example above, Nutech is the sponsor name.

Why is this a carrier requirement?
Mobile users receive a wide variety of business-to-consumer messages: credit card balance, retail offers, school notices, appointment reminders, transportation statuses, threshold alerts, employee notifications. Having a standard format for identifying the program and its source at the beginning of the message provides a better user experience

Program Name

This is the name of your service, and is also referred to as the “product disclosure.” It should appear following the sponsor name in your texts.

NuTech Latest: Get the top tech stories of the week! 1msg/week. Msg&DataRatesMayAply. Reply HELP for help, STOP to cancel. 18001234567.

While the full program name is actually “NuTech Latest” in this example, that is only acceptable because “NuTech” is also the sponsor name. “Latest” tells us what type of service is being provided. While “News” is a common program name, carriers are looking for something more intuitive. “Latest” gives the end-user an idea of what they’re receiving–the buzz about tech.

Why is this a carrier requirement?
Mobile users receive a wide variety of business-to-consumer messages: credit card balance, retail offers, school notices, appointment reminders, transportation statuses, threshold alerts, employee notifications. Having a standard format for identifying the program and its source at the beginning of the message provides a better user experience

Additionally, many sponsors have multiple programs. Including both sponsor and program name clarifies the program from which the message has been sent.

Product Description

In many occasions, simply giving the program name is not enough of a description for the end-user to understand fully what sort of messages they are receiving. Because of this, a product description should be added. This can be a short sentence, or even just a couple of words.

NuTech Latest: Get the top tech stories of the week! 1msg/week. Msg&DataRatesMayAply. Reply HELP for help, STOP to cancel. 18001234567.

In this example, this sentence makes it clear to the user what they will accomplish by receiving these messages.

Why is this a carrier requirement?
The product description helps set proper user expectations for the types and purposes of the messages they will be receiving.

Message Frequency

For One-Time Programs, this will manifest as the number of messages given out to the end-user in response to each message they send to the service.

For many applications, the message frequency cannot be precisely predetermined by the content provider. In this case, the frequency included in the message content should relate to the expected message frequency under normal circumstances.

CTIA audit standards accept “1 msg/query” and “Msg frequency varies by user” (the word “frequency” cannot be abbreviated).

NuTech Latest: Get the top tech stories of the week! 1msg/week. Msg&DataRatesMayAply. Reply HELP for help, STOP to cancel. 18001234567.

For subscription programs, the “2msg/query” would be replaced by the number of messages given periodically over time by the program without prompt, such as “3msg/week.”

Why is this a carrier requirement?
The message frequency lets mobile subscribers know how often they should expect messages from the program to which they’ve subscribed.

Msg&Data Disclaimer

Commonly abbreviated to “Msg&Data rates may apply” or “Msg&DataRatesMayAply,” this phrase notifies the customer that text message correspondence with your mobile program is not free, and instead costs the same amount of money as correspondence with, say, another consumer. Remember that the phrase “standard rates may apply” is no longer accepted. The most common wording is shown below in the example.

NuTech Latest: Get the top tech stories of the week! 1msg/week. Msg&DataRatesMayAply. Reply HELP for help, STOP to cancel. 18001234567.

The replacement of the ampersand with the word “and” spelled out in full, and the removal of one p from the word “apply” are also accepted.

Why is this a carrier requirement?
End-users must be aware that they may be charged by the carrier to receive and send messages associated with the program.

HELP/STOP Instructions

HELP and STOP keywords must work in the native language of the program as well as English. These pieces can appear in one sentence, or separated.

NuTech Latest: Get the top tech stories of the week! 1msg/week. Msg&DataRatesMayAply. Reply HELP for help, STOP to cancel. 18001234567.

Please note that the replacement of “for” and “to” with “4” and “2” is not accepted.

Why is this a carrier requirement?
The mobile end-user must be able to receive support for their mobile program, or stop their mobile program at any time.

Customer Support Info (Support Email or Toll-Free#)

This piece required in the Initial/Opt-in MT as well as the final Opt-out MT. Although the HELP menu itself provides additional customer support information, the quick contact info is outside of the HELP menu.

NuTech Latest: Get the top tech stories of the week! 1msg/week. Msg&DataRatesMayAply. Reply HELP for help, STOP to cancel. 18001234567.

The Customer Support Info can appear as either a toll-free number or a support e-mail address. Typically, two of the three are accepted in a given message, while the third is not. For example, you need either a URL or a toll-free number in your initial opt-in response, but either an e-mail or toll-free number in your opt-out as due to recent changes, the URL is no longer accepted. However, regardless of which two are accepted, only one is required in any given message–you need not include both.

If you are using an Aerialink leased toll-free number (versus a BYON toll-free number) in your Short Code HELP auto-response, the number must have active voice service for Customer Care and requires an additional step for setup. The inbound voice service for TFNs included in the SC help messages must be forwarded to:

  1. An active number for the brand’s customer care service in domestic US or Canada. You can enter the forwarding number in your Aerialink Platform Portal account on the codes details page.
  2. or a voice recording (provided by you and we load that on to our SoftSwitch) associated each dedicated brand number. This function does not allow user to leave a voice mail. Hence, it should identify the brand, the program and instruct user how to contact the brand for customer care. Please submit the request through our support channel and our provisioning team will load it on our SoftSwitch for inbound forwarding to a recorded message. The recording should identify the brand and instruct end user how to contact the business for customer care. The recording may be saved in .wav format.

Why is this a carrier requirement?
The quick contact info provides a means for the user to understand the terms and conditions of the program or receive direct, live support if needed.

Character-Saving Recommendations

Required compliance verbiage can take up a large number of your available 160 characters. To help make the most of the characters at your disposal, read below for tips on keeping messages short and for acceptable abbreviations to words and terms found in your needed compliance language.

Msg & Data Rates May Apply

It is perfectly compliant to leave out the spaces between words in this required component, but be sure to capitalize the beginning leter of each word so that it is conspicuous and legible, like so:

  • Msg&DataRatesMayAply

Removing the spaces will save you five characters!

Reply HELP for help, STOP to cancel

While the presence of these two items is looked at individually as-needed, if both are required in a message, combine the sentence as you see here.

Abbreviated Program Name

Your sponsor and program name are required in all of your messages—don’t have them any longer than they need to be. Always look for the shortest possible manifestation of this tag. For example, instead of “Company Alerts,” it says “Company Alrt.”

Simplified Phone Number Format

Ex: 18001234567 Leave the punctuation out of your phone numbers. Smart phones will still be able to click to dial, and you won’t eat up extra characters. Depending on your use-case, you may even want to leave off the country code.

Cut Some Punctuation

Leaving off the last period in your text doesn’t hurt your end-user’s understanding of the sentence. Look through your messages for erroneous commas and periods.

In-Message Abbreviations

Compliant Abbreviations for Required Language

  • And -> &
  • Apply -> Aply
