Comparing the advantages of long code vs. short code messages? We’ve got you covered with this explainer, which breaks down the pros and cons of each SMS medium.
What are short and long codes for texting?
Shortcodes, long codes, and toll-free numbers (TFN) are delivery vehicles for text messages.
A shortcode is a five-digit number assigned by carriers that allow for high SMS throughput. Shortcodes can be customized, are a little pricey, and can take some time to set up. They’re really great for customer service, non-collection account information, or reminders. Shortcodes can be great conduits for mass notifications. They do also support two-way messaging.
But there are some use-case-specific caveats to consider with shortcodes. For example, for collections or account recovery, shortcodes may not be the ideal delivery method depending on whether you’re a first or third-party entity. This is because carriers, who distribute shortcodes, very closely monitor the types of communications occurring over their networks and reserve the right to intercept at their discretion. To ensure your messages are landing you might want to consider a different vehicle if accounts recovery is your intended SMS application.
TFN texting is good for both one-way or two-way messaging. The throughput isn’t as high as a shortcode or a toll-free number, however. Essentially, a TFN is a 1-800 number that allows the text message to ride the same network as a phone call would.
Right now shortcode regulations don’t apply to TFNs, making them an excellent choice for a third-party collections use case.
Turning to long codes, these numbers are typically local numbers and are not super leveraged for business texting. They’re designed for person-to-person messaging and are the mobile numbers that you text your friends and family from. Their throughput is minimal at around one message per second.
The nitty gritty on shortcode texting
There are two different types of SMS shortcodes. The first type of SMS shortcode is called a “Dedicated Short Code”, which means that it will only be used by one business. For example, big organizations like Pizza Hut and Domino’s have dedicated SMS shortcode numbers that they text your delivery updates from. This means that no other business can operate on Pizza Hut or Domino’s SMS shortcode number because it’s dedicated to their specific business. When it comes to SMS marketing, most large businesses have a dedicated SMS shortcode.
The second type of SMS shortcode is called a “Shared Short Code”, which means that it’s used by many different businesses. In the case of shared shortcodes, each business shares the shortcode and is assigned a unique SMS keyword that enables the carriers to determine which organization a message belongs to.
CTIA guidelines for short codes
To protect consumers against bad actors, wireless carriers set up a group called the CTIA to enforce best practices on their networks that favor the interests of the consumer. To do this, the CTIA carries out audits on SMS programs based on the rules outlined in their CTIA Short Code Compliance Handbook. If a text messaging campaign is found to be in violation of any of the guidelines in the handbook, the CTIA grants the wireless carriers the right to deactivate that campaign.
Advantages and uses of short codes
Sending marketing texts
You’re probably familiar with seeing short codes when you receive a marketing text message from a brand, and that’s certainly their most prevalent use case. SMS short codes are great for blasting out concise sales-related messages like promotions, coupon codes and survey questions quickly.
One of the biggest upsides of short codes is they’re just that: short. They’re easy to memorize, making them ideal for when you want customers to message you, like when they’re required to text to enter a contest or opt into your subscriber list.
Reaching a large customer base
Short code messages have the distinct advantage of being able to be sent to a large volume of recipients in a matter of seconds. This makes them the text blast option of choice for enterprise companies and large agencies.
Offering two-factor authentication
The security of customer data is a paramount concern for companies, both to preserve your brand’s reputation and to avoid legal woes. Short codes are a great tool for conducting two-factor authentication, giving you another channel by which to verify the customer is who they say they are. For example, when a customer attempts to log into your bill-pay platform with an unrecognized device, you might send a shortcode text to the phone number you have on file with a verification code.
Resisting spam filters
Short code messages may have higher deliverability rates than their long code counterparts. Because the content sent via five- and six-digit short code text messages are approved during setup, the messages are less likely to get flagged as spam.
Sending non-sales content
The mass-messaging nature of short code texts makes them perfect for distributing non-sales content like emergency alerts, security notifications, weather updates. They’re a favorable messaging medium for not-for-profit organizations like local municipalities and school districts.
How to get a short code number?
There are a few ways to get a short code number for your business. The most common is to lease a short code from a third party vendor. This will give you access to all the features and capabilities of that particular provider.
Another way to get a short code number is to go through the process of applying for and obtaining one from the Wireless Telecommunications Bureau (WTB) of the Federal Communications Commission (FCC). This is a more involved process and generally takes 4-6 months to complete.
Which is better? There is no definitive answer as to which is better. It really depends on your particular needs and objectives. If you need a short code number quickly and don’t mind paying a monthly fee, then leasing from a third party vendor is probably the best option. If you have the time and resources to go through the process of applying for and obtaining your own short code number from the FCC, then that may be the better option for you.
No matter which route you decide to go, make sure you do your research and due diligence to ensure you are getting the best possible short code number for your business.
Advantages and uses of long codes
Communicating directly with customers
SMS long code texts are ideal for person-specific messages that don’t necessarily need to be blasted out ultra-fast, like order tracking info and appointment reminders. They’re set up for two-way communications, which allow the personalization of a back-and-forth conversation between a company and its customer. Learn more about the advantages of personalized conversations in our two-way SMS marketing guide.
Providing customer service
Because of their two-way capabilities, long code texts work well for situations that necessitate multiple messages between parties, like product support and troubleshooting. The continuous thread is just like a regular person-to-person text message, which is helpful if customers need to refer back to it later on.
Adding a human touch
Because a long code message is formatted like the familiar 10-digit phone number of a friend or family member, it can feel more human than a shortcode message, which is only sent by brands.
Long code numbers are less expensive than dedicated short codes, making them a cost-effective option for smaller companies or those that only wish to send a limited number of texts.
Maintaining consistency between channels
Long codes have the advantage of being able to be used for multiple purposes. They can send both SMS and MMS messages as well as make and receive voice calls and even send faxes. This helps you maintain consistency across all channels of communication.
Is one better than the others?
To make a long story short, it all depends on what your use case is—meaning what kinds of messages are you going to be sending?
Shortcodes and TFNs enable you to send rapid-fire SMS at tens of messages per second because their throughput, or the measure of data transfer per second, is high; while a long code can send around 1 message per second. So, shortcodes are great for sending SMS messages to lots of people at once in a time-sensitive manner but they’re highly monitored and subject to carrier interference. Examples of use cases that are best suited to a shortcode are:
- Marketing communications
- Broadcast messaging (large- volume texts)
- One-way notifications like updates to company policies
Another benefit of using a shortcode is that since they’re distributed and vetted by carriers themselves, they are not subject to carrier filtering or suspension for heavy traffic because they’ve been reviewed and issued by the carrier already.
Long codes are meant for person-to-person communications and fire at a far slower rate.
TFNs, or toll-free numbers, are the newest texting option for businesses. They’re 10-digit numbers and are approved by carriers for commercial use but aren’t yet as stringently controlled. Like shortcodes, they’re compatible with keyword configuration and automation. However, they afford the added bonus of blended communication. That is, you can take calls on your TFN and enjoy the legitimacy that comes from having your text code resemble an actual number.
Why Text in the first place?
Asynchronous channels like SMS and webchat have dramatically grown in popularity for business communications. This year alone, the number of people texting globally will rise to 3.5 billion. By 2025 the number of texters will double to 6 billion.
SMS messaging is a great way to get instant visibility with your customers. What’s more, going beyond one-way mass texting campaigns presents an even greater opportunity to grow your business and delight customers. Bidirectional or two-way SMS interactions provide more opportunities to get to know customer preferences, build loyalty, and even attract new business.
With the potential to 5X your reach, adding SMS to your communications stack should be an easy decision.
Deciding exactly what kind of texting you’d like to deploy requires a bit more thought. Hopefully, this outline of the basic vehicles for SMS has helped inform your options.
