If you have received a text message from the 6-digit number 778273, it is a legitimate and urgent security notification. The 778273 short code is classified as a shared short code, which means it is used by several major technology and financial platforms to deliver One-Time Passcodes (OTPs) for Two-Factor Authentication (2FA).
The message itself is designed to protect your account. However, the reason you received it may be a cause for immediate concern, as it often signals that someone else is attempting to access your online account.
This guide identifies the common senders, explains why you should never block this number, and outlines the critical steps to take if the code was unexpected.

CRITICAL ACTION: If You Receive an Unsolicited Code
If you received a verification code from 778273 but you were not attempting to log in, reset a password, or make an account change, this is a major security alert.
It means that a hacker or scammer has successfully guessed or stolen your password and is currently trying to log into your account using your phone number to get past the 2FA.
Immediate Security Steps:
- DO NOT SHARE THE CODE: Never read the code to anyone who calls or texts you asking for it, even if they claim to be security or support staff. Legitimate companies will never ask you for this code.
- Change Your Password: Immediately log in to the service mentioned in the text (or all your major accounts, including email and social media) and change your password to a strong, unique one.
- Upgrade 2FA: If available, switch your Two-Factor Authentication method from SMS (text codes) to a dedicated authenticator app (like Google Authenticator or Authy), which is far more secure against text-based scams.
Low Concern: Wrong Number Scenario
If the text mentions a service you do not use (e.g., you get a code for a bank you are not a customer of), it most likely means someone else mistyped their phone number during their setup process. You can safely ignore and delete the message.

Managing the 778273 Short Code
Is the 778273 Short Code a Scam?
No. The number itself is legitimate. It is an official security tool. The scam risk lies in the action you take when receiving the text.
Can You Stop Texts from 778273?
Blocking this number is highly discouraged.
- Why it doesn’t work: Transactional codes are sent on-demand by the network. Replying STOP is generally ineffective for security codes.
- The Risk: If you block 778273, you will be unable to receive the necessary verification code when you lock yourself out of your account or get a new device. This could lead to a lengthy process to regain access to your own accounts.
The only way to prevent these texts is to stop using your phone number for 2FA on every single account and switch entirely to an authenticator app.
Frequently Asked Questions (FAQ)
What does it mean if the text came from a number in the 778-273-XXXX range?
If the text came from a 10-digit number that contains the 778-273 prefix (like 778-273-5555), it is not the short code. It is a standard phone number from the 778 area code (British Columbia, Canada). While this is a common North American area code, it should be treated with suspicion if the text is unexpected.
How can I make my 2FA more secure than SMS texts?
The safest way to secure your accounts is to use a dedicated authenticator app (like Google Authenticator, Microsoft Authenticator, or Authy). These apps generate codes that do not travel over the vulnerable cellular network, making them immune to text-based interception scams.
How long does the code last?
The passcodes sent from 778273 are time-sensitive, usually expiring after only 5 to 10 minutes. This short lifespan is a key security feature designed to prevent hackers from successfully using a delayed or intercepted code.
