For businesses seeking a more efficient and effective way to connect with customers, SMS short codes offer a powerful solution. These 6-digit numbers simplify communication, making it easier to send messages that capture attention and drive action.
Unlike traditional 10-digit phone numbers, short codes are easy to recognize, quick to use, and perfect for high-volume messaging. Customers can effortlessly opt-in to receive promotions, updates, and alerts without the hassle of entering long phone numbers.
While there is a cost associated with leasing a short code, the return on investment is often significant, with higher engagement and conversion rates. In this blog, we’ll explore how 6-digit short codes work, why they’re so effective, and how they can enhance your customer communications.
What are 6-digit phone numbers?
Short codes, introduced by wireless carriers in 2003, were designed to meet the growing demand for efficient mass messaging. They are 6-digit numbers specifically built for high-throughput, application-to-person (A2P) messaging, making them ideal for sending critical, time-sensitive updates like authentication codes, alerts, and promotional notifications. Unlike traditional 10-digit long codes, short codes offer:
- Faster delivery: Thousands of messages can be sent per second.
- Better prioritization: Carriers prioritize short codes, ensuring high deliverability for important updates.
- Simplified user experience: Their shorter format makes them easier to recognize and remember.
How are 6-digit numbers used?
The versatility of short codes extends across multiple industries. Here are some key applications:
Retail and E-commerce:
Businesses use short codes to announce flash sales, send discount codes, and share product updates.
Examples:
“Text DEAL20 to 123456 to get 20% off your purchase today!”
“FLASH SALE! Text SALE to 654321 for exclusive early access to our 50% off deals.”
“Sign up for SMS alerts by texting VIP to 456789 and receive free shipping on your next order.”
Healthcare:
Appointment reminders, public health notifications, and patient engagement campaigns are made seamless with short codes. Enhance patient experiences and rapport by improving healthcare communication, reducing appointment no-shows with SMS alerts, delivering time-critical emergency health services, and optimizing public health campaigns.
Examples:
- “Your appointment with Dr. Smith is scheduled for tomorrow at 3:00 PM. Reply YES to confirm or RESCHEDULE to change.”
- “Public Health Alert: Flu vaccine clinics now open. Text VACCINE to 789123 for locations near you.”
- “Reminder: Please fast for 12 hours before your blood test tomorrow at 8:00 AM. Questions? Text HELP to 987654.”
Finance and security:
Banks and financial institutions rely on short codes for two-factor authentication (2FA) and account activity alerts.
Examples:
- “Your account balance is $1,234.56. For more details, text INFO to 123123.”
- “Your one-time verification code is 876543. It will expire in 5 minutes.”
- “Alert: A transaction of $500 was made on your credit card ending in 1234. Text FRAUD to 456123 if this wasn’t you.”
Logistics and transportation:
Ridesharing services and courier companies use short codes for real-time updates, such as delivery status and driver notifications.
Examples:
“Your package will arrive today between 1 PM and 3 PM. Track it here: [link].”
“Driver Alex is 5 minutes away in a blue Toyota Camry. Text SUPPORT to 654987 if you need help.”
“Your ride to JFK Airport is confirmed. Driver John will arrive at 6:15 PM. Reply CANCEL to cancel.”
What are the advantages of 6-digit numbers?
Short codes offer many distinct advantages over traditional communication methods, revolutionizing how businesses connect with their audience. Their efficiency, reliability, and user-friendly nature make them a preferred choice for high-volume messaging campaigns. Here's a detailed breakdown of their unique benefits:
High throughput:
Short codes support the dispatch of many messages per second, a critical feature for businesses managing large-scale campaigns. Plivo’s SMS API takes this further by providing a throughput of 100 messages per second for short codes with room for scalability.
Improved deliverability:
Messages sent via short codes are prioritized by carriers, reducing the likelihood of being filtered as spam. This ensures critical notifications, such as system outages or payment confirmations, are received promptly.
Memorability and branding:
Vanity short codes (e.g., “PLIVO” or 75486) reinforce brand recognition while simplifying the user experience. Plivo’s API supports vanity short codes, ensuring seamless integration with your branding strategy.
Compliance:
Short codes are inherently TCPA-compliant when used correctly. Plivo’s opt-out handling and real-time redaction tools simplify adherence to regulations, protecting your brand from legal pitfalls.
Compliance and opt-in requirements
Navigating the regulatory landscape is crucial for any business utilizing short codes. Under the Telephone Consumer Protection Act (TCPA), explicit customer consent is required before sending promotional messages. This is typically achieved through keyword opt-ins, such as:
- A customer texting “SUBSCRIBE” to your short code.
- The customer’s agreement to your terms of communication.
Plivo’s compliance features:
- Built-in opt-out management, ensuring recipient requests like “STOP” or “UNSUBSCRIBE” are processed automatically.
- Detailed documentation and support to guide businesses through TCPA and CTIA compliance requirements.
Types of short codes
When choosing a short code, businesses must decide between two options:
Random short codes:
Carriers assign these codes sequences of numbers provided by wireless carriers, offering businesses a cost-effective option for high-volume messaging. These codes are chosen at random, without input from the business, which makes them less personalized compared to vanity short codes.
However, their functionality remains identical, making them an excellent choice for businesses where branding isn’t the primary focus, but reliable and efficient messaging is. For example, a logistics company sending delivery notifications or a healthcare provider sharing appointment reminders may prioritize the affordability and utility of a random short code over the memorability of a vanity code.
Random short codes deliver the same performance benefits, such as high throughput and carrier prioritization, without the added expense of customization.
Vanity short codes
Vanity short codes are fully customizable 6-digit numbers that allow businesses to align their messaging strategy with their brand identity. These codes are typically chosen to spell out a word or phrase associated with the business, like “PLIVO” (75486), making them highly memorable for customers. The customization not only aids in recall but also builds trust and credibility by reinforcing the brand every time the code is used.
While vanity short codes are more expensive than random ones, their value lies in their ability to create a cohesive and recognizable brand experience. For instance, a retailer running nationwide loyalty programs or a media company promoting a recurring event might find the investment worthwhile to maintain a strong brand presence in every interaction.
Since the industry-wide discontinuation of shared short codes due to security concerns, dedicated short codes—whether random or vanity—have become the norm. These provide businesses with exclusive use of their short code, ensuring messages are not only delivered but also free from the risks of being flagged or associated with other entities.
How to lease and acquire a 6-digit phone number?
Leasing a short code involves navigating carrier requirements and compliance approvals. The process includes:
- Selecting a random or vanity short code based on your goals and budget.
- Completing carrier documentation, including details on message types and compliance measures.
- Testing and launching your campaigns.
