Site Security
These security features apply to all websites hosted by Citi. We will let you know when you are leaving a Citi site.
How We Protect Our Site
To ensure secure transactions for our cardmembers, Citi® uses Secure Sockets Layer (SSL). SSL encrypts, or scrambles, your user name and password before they leave your computer and then unscrambles them at the receiving end--our corporate Internet server.
Check your browser to be sure it has the added security of 128-Bit Encryption.
Secure Firewalls
We protect our secure computer servers with numerous firewalls and specialized hardware and software that control all external communications with our computer network. We constantly monitor these firewalls to prevent security breaches.
Email Safety -- Phishing and SMishing Schemes
Phishing is a kind of credit and debit card fraud. By pretending to email from a bank or similar site, scammers "fish" for account numbers, passwords, Social Security numbers, etc. They trick consumers into divulging sensitive information so that unlawful charges can be made on the consumers' accounts. “SMishing”, named for SMS (Short Message Service) the technology used for cell phone text messages, is a similar kind of fraud. It uses text messages to deliver the “bait” to get clients to divulge personal financial information.
A number of fraudulent email and text messages that claim to be from Citi Cards, Citibank, or Citigroup have been forwarded to us by our cardmembers. These schemes change frequently and often have links or attachments with links. Users who click on the links are taken to look-alike or "spoofed" sites where they are asked to enter personal data. Text message verbiage varies, but may direct users to a web site or phone number, and usually contains something that claims to require immediate attention.
Examples of Phishing Emails:
Your Citibank account was temporarily suspended

Security Questions Within Account Online
Citi is serious about account safety. That's why we're requiring all Account Online users to create security questions. We may periodically ask you to answer those questions in Account Online as a quick identity check. That way, when you drop in to do business, we'll know it's you.
Check Email for Security
The best way to verify a Citi email is to look for the Email Security Zone header at the top of the email. Every Citi Cards email includes your first name, last name, and the last 4 digits of your card number.
Please note that Citi will never ask you for your PIN number, and will never include your full account number, password or social security number in an email--only the last four digits. If you receive an email claiming to be from Citi that includes or asks for your full account number, password or social security number, do not respond to it. Instead, forward it to spoof@citicorp.com.
Report Email and Text Message Fraud
If you suspect that an email or text message appearing to be from Citi is fraudulent, forward it immediately to spoof@citicorp.com. An Internet Security Specialist will investigate. If you have replied to an email or text message with personal information, and now believe the communication to have been fraudulent, call us at the toll-free number on the back of your card. We will issue a replacement.
Sign On Securely
Your security is important to us.
You can safely access your account from Cardmember Sign On because the new Citicards.com uses a secure "https" address to ensure that your personal information is protected.
When you sign on, your User ID and Password are immediately encrypted using Secure Sockets Layer (SSL), and sent to Citi Cards. No one but Citi can then access that information.
If you are directed from an email to any other Citicards.com web page that requires entering personal information and want to know if the page is valid and secure:
- Locate your browser's padlock or key icon.
- Double-click the icon to open the SSL Certificate.
- Click on the Details tab.
- Click on Subject.
- Look for "O = Citigroup".
