How to Implement a Successful Common Short Code (CSC)
Mobile marketing has become a key channel for businesses looking to communicate with consumers directly and effectively. It offers unprecedented reach with much easier access to end users. Common Short Codes (CSCs) represent a fast-growing channel that offers direct communication with consumers, anytime and anywhere through a common medium – Short Message Service (SMS) commonly referred to as just “texting.” This paper provides a primer on CSCs for the marketer looking to use this fast-growing phenomenon to reach customers. This paper will:
- Review the CSC life cycle
- Describe the CSC value chain
- Discuss CSC applications and challenges
- Outline important ways organizations can reliably monitor the use of the CSC channel.
1. How to Implement a Successful Common Short Code
Mobile phones are the preferred mode of digital communication. There are more than 3.3 billion mobile phone subscribers in the world, more than the number of landline subscribers. Over the past decade, the mobile phone has morphed from a simple communication device into a potent marketing tool. “Mobile marketing” has become a new discipline consisting of a unique and complex mix of technologies, business skills, and marketing expertise. This burgeoning market is driven by consumer receptiveness, carrier openness, and technological advances.
Today, more than 92.5 million consumers actively text message in the United States, providing a fairly accurate estimate of potential audience size for a given messaging campaign. – M:Metrics, “Common Short Code: Cracking the Mobile Code
Mobile marketing makes use of multimedia messaging (MMS), text messaging (SMS), and its related cousin Common Short Codes, to deliver advertisements and downloadable content (games, videos, podcasts, ringtones, wallpapers) to the mobile phone. The MMS, SMS, and CSC alphabet soup provides marketers with a way to pull eyeballs to the mobile Web to connect brands with consumers.
Arguable, SMS, with more than 350 billion text messages exchanged across the world’s mobile networks every month, is the most dominant marketing tool. According to the Yankee Group, more than 15% of these messages are classified as commercial or marketing messages.
Common Short Codes, also known as just short codes, are SMS messages that are exchanged between a person and an application. CSCs are the preferred channel in the United States for brands to connect with mobile users. For any brand or enterprise, a CSC translates into one common address, one call-to-action that reaches more than 235 million mobile customersiSee.
CSCs are easy to obtain and use and are becoming more and more popular in advertisements, in TV shows, and on consumer goods.
CSCs have many advantages:
- Easily reaching millions of prospects and customers;
- Ensuring higher response due to the ease of responding;
- Riding the phenomenal popularity of text messaging;
- Leveraging a popular and ubiquitous platform for new technologies and applications;
- Enabling new marketing messages (e.g., ringtones, wallpapers, etc.); and
- Utilizing a channel where the cost of communications is already bundled into the monthly phone service contract.
Given their ease of use, CSC-based campaigns increase consumer response to advertising and marketing promotions significantly. CSCs simplify the data entry process and the ability to participate in campaigns. For example, GQ magazine realized the power of the mobile platform by using short codes to reach its readership. According to GQ, 100% of their readership owns cell phones and 93% use their phones for text messaging. One campaign GQ launched was a text-to-win promotion using its short code 47624 (which translated to GQMAG, a vanity CSC), which consumers could use for a chance to win a Kid Rock CD. According to Scott Carlis, GQ’s executive marketing director, 64% of contestants entered within the first day of the campaign launchiiIDC, “Common Short Codes: The Time Is Now for Mobile Marketing and Outreach,” January, 2007.
CSCs have also be used for voting or polling, “text2win” sweepstakes, coupon redemption, gaming, and more recently for commerce and banking – some of these applications, though by no means all, are time sensitive. Dropped messages or delivery delays can cause major problems for the provider in addition to inconveniencing consumers. Continuous monitoring is the most important stage in the CSC life cycle. Slow delivery or low availability impacts revenue across the entire ecosystem. All parties in the ecosystem need to proactively monitor their services to stay alive in this competitive business.
2. Opportunities with Common Short Codes
In early 2006, a leading convenience store ran a successful in-store promotion using SMS. The retailer, which owns and operates approximately 500 convenience stores in the greater mid-Atlantic area of the United States, is known as a concept leader and technology innovator. After running the program for six months in control stores, the retailer realized a 3% increase in sales as a direct result of the campaign—even during a period of rapidly escalating gas prices, which caused sales to decline in non control stores. Only 4.8% of recipients opted out of the program after opting in, and the company realized a 30% overall redemption rate on all SMS mobile coupons. While not all CSC campaigns may be as successful, the potential for CSC is huge.

CSCs are useful in a number of ways. The table below lists a few of the application categories that are enabled through CSCs. New applications are being created every day.
3.1 Wireless Service Providers or Carriers
Wireless service providers, or mobile carriers, as they are commonly referred to, own the infrastructure that receives and delivers messages from and to the subscriber. Since SMSs are not free, carriers also serve as collection agents for the entire value change. Usually they are not visible in the campaign except for the charges that show up on subscriber's monthly bills. Practically every campaign traverses multiple wireless services providers or carriers.
The CSC channel is not free. Most subscribers pay a fee per SMS or for an SMS bundle, such as 500 per month. CSC messages are no exception. For normal SMSs, these charges range from 5 to 10 cents per message (some service plans may offer cheaper rates). However, premium-rate short code services can charge as high as a few dollars per short code message. This amount shows up on the subscriber’s monthly bill and is collected by the service provider (i.e., the mobile carrier). The service provider keeps its share of the revenues and distributes the remaining between the aggregator and content and application providers.
4. CSC Lifecycle
Implementing a CSC campaign is a multistep process. We’ve outlined these steps here, though of course there is more to say about each, and we encourage serious marketers to explore the subject further.
5. Measuring Quality of Service
The use of CSCs, the number of CSC applications, and the number of subscribers using CSCs are all increasing with each day. According to the wireless industry association CTIA, there were more than 2,000 CSC programs in process in March 2007ivSee. . America’s favorite TV program, American Idol, was getting more than 40 million CSC votes a week toward the end of the 2007 season. For every successful CSC promotion, campaign, or service, it is important to ensure a satisfactory end-user experience. The two dimensions of user satisfaction are performance and availability. At a minimum, each CSC message needs to successfully complete the round trip between the user and application within a “reasonable” amount of time. And application requirements vary, so QoS must always be calibrated according to the object of the specific application or service.
Performance is measured as the end-to-end elapsed time for the round-trip delivery of the CSC message between the user and application.
Availability is a percentage measure of the number of successful round-trip deliveries of the CSC message between the user and application. Unsuccessful messages include incorrect messages, messages that were never sent, and messages that are not acknowledged within a predefined time window.
5.3 Application Requirements
Each application has different requirements for performance and availability. For example, a commerce application needs to guarantee a response to every sender, while a banking application needs to ensure a quick response.
The table below describes the importance of these requirements for various applications.
5.4 Quality of Service VariesPerformance and availability vary significantly across carriers, aggregators, times of day, application and content providers, and campaigns. For example, the two graphs below show performance and availability for the same short code campaign across five different aggregators on the same North American wireless service provider.
The performance chart below shows significant variation in performance among all five aggregators as measured in seconds. Aggregator E consistently fairs the worst. The second chart below it measures availability in percent (with 100% being the desired outcome) and shows an early dip for aggregator C and then multiple dips for Aggregator D, indicating problems that would affect campaign performance.
As a marketer, you are trying to show maximum return for your campaign. Poor CSC performance and availability can sink your campaign. You have to work with your mobile operations team to pick an aggregator that has a consistently good track record.
6. Poor Performance and Availability Implications: The Need for Monitoring
Given the variability in performance and availability, every marketer should track campaign performance and availability. Poor performance and poor availability can have severe business implications, ranging from loss of revenue and impact on brand image to threats of litigation – especially where commerce is involved. Given the complex nature of the value chain, it can be hard to locate the root cause of the problem. Even though there are service-level agreements (SLAs) governing each section of the value chain, just having an SLA is not enough to guarantee performance.
Coca-Cola runs promotions where consumers redeem cap codes from 20-oz. bottles via SMS-enabled mobile phones. They simply use their phones to dial the CSC 2653 (which spells out COKE), then visit a Web site to enter in contests for prizes. Even if 1% of these messages were lost (a conservative number based on some of the research conducted by Keynote) – Coca-Cola’s image would be severely impactedvSee.6.1 Revenue Loss
Given the huge reach of the CSC channel (potentially any mobile phone subscriber), all parties are susceptible to significant litigation risk. Cell phone complaint sites are full of messages from irate customers who sent a short code to end a paid service that was not stopped even after multiple messages.viiiFor example, see http://classactionconnect.com/cell_phone_issues/2007/08/30/thumbplayinc48000710736607540443/# comment2781
In addition, the FCC is considering laws to manage CSC usage and support by carriers. In certain cases, wireless providers have barred certain campaigns or organizations on their channels. In certain other cases, carriers selectively deprioritize some traffic – leading to poor availability and poor performance.6.4 Identifying the Bottlenecks
CSC delivery involves multiple carriers since campaigns are rarely carrier or geography specific. However, as the chart in the last section shows, performance across aggregators on the same carrier varies significantly. The reasons for these variations range from the performance guarantees or revenue sharing agreements or even the hardware that the aggregator is using.
While the possibility of hardware failure exists at every connection point, it is more likely that a service provider may experience a large traffic burst, or an aggregator may be prioritizing higher-value traffic over lower priority messages. It is hard to pinpoint where the choke points occur without detailed monitoring across the entire value chain.
The diagram below indicates a three day outage for the short code which resulted in drop in availability across all 4 carrier networks.
in the CSC value chain signs an SLA guaranteeing 99.99% uptime, there is a strong need for independent monitoring to ensure that the SLAs are being met and performance is not slipping at the interfaces between the various players.
The plot below tracks the performance of a short code that was monitored by Keynote SystemsixSee http://www.keynote.com. During an outage marked with the red cluster, most messages were not being delivered within the three minute SLA given to the customer; thus breaking the SLA and effecting the end user.
The potential for revenue loss, negative impact on brand image, and the threat of litigation combined with the need to monitor a complex value chain for enforcing SLAs all point to the need for independent monitoring from an unbiased, trusted entity that can quickly identify a problem, pinpoint its exact origin, and provide guidance on how to fix it.7. Best Practices for Monitoring
Clearly, there is a strong need to monitor CSC campaigns from an end-user perspective. This section lists the best practices for thorough and useful monitoring.Conclusion
CSCs represent a new marketing channel that is fast gaining traction because of its simplicity and reach. American Idol alone in 2007 was receiving over 40 million short code messages per week. Delivery of a CSC campaign involves multiple players – wireless service providers, aggregators, content providers, and application providers. It is fairly straightforward to sign up for a short code program. However, given the complex nature of the value chain, CSC campaigns run the risks of lost revenue and poor brand experience, and are exposed to the threat of litigation due to poor performance. All of these risks require real-time monitoring of SLA agreements and visibility into real-time performance across the delivery chain to identify the actual failure points. An independent monitoring solution ensures that the campaign is meeting availability and performance goals and provides insight into every player’s performance, thus allowing marketers to choose the right partners.Appendix: Getting Help Selecting Your CSC Partner
