When that number is a short, five or six-digit code, it adds another layer of mystery. If the 97539 short code has recently appeared in your message inbox, you’re not alone.

What Exactly Is a Short Code?
Before diving into the specifics of the 97539 short code, it’s important to understand the technology behind it. A short code is a five- or six-digit number used by businesses, organizations, and brands to send and receive text messages in high volumes. Unlike a standard 10-digit phone number, short codes are designed for mass communication and are often used for marketing campaigns, alerts, and, most commonly, security authentications.
These codes are leased from a national registry and are regulated by the Cellular Telecommunications Industry Association (CTIA). There are two main types of short codes:
- Dedicated Short Codes: These are used by a single company for all their messaging needs. This offers a more branded and exclusive communication channel.
- Shared Short Codes: As the name suggests, these are used by multiple companies. To differentiate their campaigns, each business uses specific keywords. For example, you might text “DEALS” to a shared short code for one company’s promotions and “APPT” to the same number for another company’s appointment reminders.
Understanding the distinction between dedicated and shared short codes is key to deciphering the origin of a message from a number like the 97539 short code.
Decoding Messages from the 97539 Short Code
The 97539 short code appears to be a shared short code utilized by various companies for a critical function in today’s digital world: two-factor authentication (2FA). Two-factor authentication is a security measure that adds a second layer of protection to your online accounts beyond just a password. When you log in to a service that has 2FA enabled, you’ll be prompted to enter a temporary code sent to your phone to verify your identity.
Numerous online reports from users across the United States indicate that they have received messages from the 97539 short code containing verification codes for a range of popular services. Some of the most frequently mentioned companies associated with this short code include:
- Airbnb: The vacation rental platform often uses the 97539 short code to send verification codes when you log in from a new device or make changes to your account.
- Tinder: The popular dating app has also been reported to use this short code for account verification and login purposes.
It’s highly probable that other companies also use the 97539 short code for similar security and verification purposes. Therefore, if you receive a text from this number, it’s likely a legitimate two-factor authentication code for a service you use.
Why Did I Receive a Text from the 97539 Short Code?
There are several reasons why a message from the 97539 short code might land in your inbox:
- You Initiated a Login or Account Action: The most common reason is that you, or someone with your password, attempted to log in to an account that has two-factor authentication enabled. The service then sends a verification code from the 97539 short code to the phone number associated with your account.
- Someone Mistyped Their Phone Number: It’s possible that another user of a service that utilizes the 97539 short code accidentally entered your phone number when signing up or changing their contact information. In this case, you would receive their verification code in error.
- A Potential Security Concern: In some instances, receiving an unsolicited verification code could indicate that someone is trying to gain unauthorized access to your account. They may have your password and are now being thwarted by the two-factor authentication step.

What to Do if You Receive a Message from the 97539 Short Code
Your course of action will depend on whether you were expecting the message or not.
If You Were Expecting the Code:
If you were in the process of logging into an account or performing an action that requires verification, simply use the code provided in the text message to complete the process. This is a standard and secure procedure.
If You Were Not Expecting the Code:
Receiving an unexpected verification code from the 97539 short code should prompt you to take immediate action to secure your online accounts.
- Do Not Share the Code: The code is a key to your account. Never share it with anyone.
- Change Your Password Immediately: If you receive an unsolicited code, it’s a strong indicator that the password for the associated account may be compromised. Log in to the service mentioned in the text (or the service you suspect it is from) and change your password to a new, strong, and unique one.
- Review Your Account Security: Take this as an opportunity to review the security settings on your online accounts. Ensure that two-factor authentication is enabled wherever possible.
- Ignore and Delete the Message: Once you have secured your account, you can safely ignore and delete the text message. Do not reply to the message unless you intend to opt-out of all communications from that short code.
How to Stop Unwanted Messages from a Short Code
If you are receiving messages from the 97539 short code that are not relevant to you, or if you simply wish to stop them, you have a couple of options. The Telephone Consumer Protection Act (TCPA) provides consumers with the right to opt-out of receiving text messages from short codes.
- Reply “STOP”: The most effective way to opt-out is to reply to the message with the word “STOP”. You should receive a confirmation message indicating that you have been unsubscribed. It’s important to note that because the 97539 short code is a shared code, replying “STOP” may unsubscribe you from receiving messages from all companies that use this code. This could include legitimate verification codes you may need in the future.
- Block the Number: If you continue to receive unwanted messages, you can block the 97539 short code directly on your smartphone. Both Android and iOS devices have built-in features to block specific numbers.
The Broader Context of Short Code Messaging
The use of short codes like the 97539 short code is a well-established and legitimate practice in the United States. It allows for efficient and reliable communication between businesses and consumers. While the potential for receiving unsolicited messages exists, the benefits of enhanced security through two-factor authentication often outweigh this minor inconvenience.
conclusion
By understanding what the 97539 short code is, the services that use it, and how to respond to its messages, you can navigate the world of digital communication with greater confidence and security. Always remain vigilant about your online account security, and treat any unexpected verification code as a prompt to review and strengthen your digital defenses.
