What Are Short Codes?
An SMS short code is a unique 5-6 digit phone number that can send and receive SMS and MMS messages at high volumes in a short period. These numbers are shorter than the usual 10 digit phone number we’re all so used to for our personal cellphones.
An SMS short code service is the best choice for companies large and small looking to brand their mobile messaging campaigns to all their customers and leads. Watch our video to learn more about what an SMS short code is.
Short Code BenefitsWhen Should I Use Short Codes?
The best time to use a short code is when you want to send mass SMS to a large audience quickly. You should also use them when sending text messages containing promotional content. This way they won't get flagged or marked as spam like they normally would with Long Codes. Overall, short codes are perfect for:
- Emergency Notifications
- Appointment Reminders
- Two-Way Texting
- Two Factor Authentication
- SMS Marketing
- Autoresponders
Shared vs. Dedicated Short Codes
Due to such high detections of spam with shared SMS short codes, many companies (including CDYNE), have stopped offering them as a product.
Shared Short Codes
A shared short code, also known as a common short code is a 5 or 6-digit phone number that's used by multiple organizations to send text messages, hence its name shared.
One of the main reasons organizations use this type of number when sending texts is because they're less expensive than their counterpart, dedicated short codes. Shared SMS short codes can range anywhere from $500 - $1,000 per month and are a great match for anyone looking for an affordable shortcode service.
Dedicated Short Codes
Dedicated short codes are 5 or 6-digit phone numbers that are used by only one organization to send their text messages.
They're the perfect solution for established companies looking to brand their text messaging campaigns with unique mobile keywords that capture customers' attention and boost conversion rates. There are two types of dedicated SMS short codes: vanity codes and random codes. The differences between the two of these dedicated SMS short code types are outlined below.
The Different Types of SMS Short Codes
Random Short Codes
Random short codes, also known as non-vanity short codes, are random 5 or 6-digit phone numbers that are assigned to organizations by the phone carriers after they've completed the entire short code provisioning process.
Remember, you have no control over what number you receive once your applications been approved. Most organizations use this type of short code in today's market because they're a lot less expensive than their counterpart, vanity codes.
Vanity Short Codes
Vanity short codes are 5-6 digit phone numbers that you can customize. This means you have the power to choose what number your customers see when they open your text messages if they aren't already taken by another organization.
Vanity SMS short codes are much more beneficial in the sense that they're more memorable than random SMS short codes, and they give you the best chance at branding your organization/business. For example, let's say you owned a company called 123 Real Estate. A cool custom vanity code for this fake company would be 123-123 for branding purposes.
Short Code Service Benefits
Unlimited Mobile Keywords
Mobile keywords boost customer engagement, conversions, sales, and revenue. With dedicated short codes there's no limit to how many keywords you can have for your SMS campaigns.
Branded Phone Number
Dedicated short codes give you the power to customize your SMS campaign's 5 or 6-digit phone numbers. This is extremely useful and can boost your organizations' sales and branding.
Text Messaging Control
Dedicated short codes give you the power to build optimized SMS campaigns without all the spam violations and brand confusion of shared short codes.
Quality Network Throughput
It doesn't matter whether it's inbound or outbound text messages your organization is sending or receiving. Dedicated short codes have what it takes to scale to all your business's texting needs.
MMS & SMS Short Codes for Texting
Short codes have the capability to send mass SMS messages and multimedia messages (MMS). It's important to remember when dealing with SMS short codes is that they can send and receive SMS and MMS messages at very high volumes, and the messages being sent can contain promotional content. Keep in mind, before your SMS short code can ever send a multimedia text message, the content must first be preapproved by the phone carriers during the short code provisioning process.
Short Codes, Toll-Free, and 10DLC
There are a few differences between short codes and the other numbers types you can choose between as an alternative. Short codes are 5-6 digits long, whereas the other options (toll-free and 10DLC) are 10 digits long and send messages at lower speeds per second.
Short codes (vanity & random) are also more expensive than 10 digit numbers (toll-free and 10DLC). It can also take anywhere from 6-8 weeks to get a short code number approved, whereas l0 digit numbers, AKA SMS long code numbers, take 1-2 days. Also, it’s essential to keep in mind that 10 digit phone numbers are subject to carrier spam/content filters, where short codes typically aren't.
SHORT CODE | 10DLC | TOLL-FREE |
---|---|---|
5-6 Digits | 10 Digits | 10 Digits |
$1,000-1,500 per month | $4-10 per month | FREE |
600+ messages per second | 50+ messages per second | Maximum Throughput Available |
Approval Process Required | Approval Process Required | Approval Process Required |
6 to 8 Week Approval Time | 1-3 Day Approval Time | 1-7 Day Approval Time |
Opting In & Out of Short Codes
Opting out of short code messages is simple and easy for all recipients. They have to respond with “STOP, UNSUBSCRIBE, etc.” and the short code API will remove them from your SMS campaign. When recipients opt into your messaging campaign, they’ll also be welcomed with a confirmation SMS to let them know they will receive your messages whenever you send them out.
