Where to find the Citibank business login page
The Citibank business credit card login is located at citibank.com under the business banking section. You will not find a separate login portal for business cards — all Citibank business accounts, including credit cards, route through the main Citibank website.
Once you land on citibank.com, look for a "Login" button, usually in the top right corner. Select "Business" from the account type options that appear. This takes you to the business login page where you enter your username and password.
If you have never logged in before, you will need to enroll first. New cardholders receive enrollment instructions in the welcome materials that arrive with the physical card, or you can call the number on the back of your card to set up online access by phone.
Key Takeaways
- Citibank business credit card login happens at citibank.com under the Business section, not at a separate URL.
- You must enroll in online access before your first login, either through the welcome materials or by calling the number on your card.
- If you forget your username or password, use the "Forgot username or password?" link on the login page to reset it.
- Two-factor authentication is required for all Citibank business logins and will send a code to your registered phone number or email.
Steps to log in for the first time
When you receive your Citibank business credit card, the welcome packet includes a temporary username and instructions for setting up your permanent password. Open citibank.com, select Business, and enter the temporary username provided in those materials.
You will be prompted to create a new password on your first login. Citibank requires passwords to be at least 8 characters and include uppercase letters, lowercase letters, numbers, and a special character. Write this password down in a find location — you will need it every time you log in.
After you set your password, Citibank will send a verification code to the phone number or email address on file for your account. Enter this code on the screen that appears. This two-factor authentication step happens on every login, not just the first one.
What to do if you cannot remember your login details
If you forget your username, go to citibank.com, select Business, and click "Forgot username or password?" on the login page. You will be asked to enter the card number associated with your account and answer security questions you set up during enrollment. Citibank will then display your username or send you a password reset link.
If you do not remember the answers to your security questions, or if you cannot access the email or phone number you registered, call the customer service number on the back of your business credit card. A representative can verify your identity using other information and reset your access.
Password resets typically take effect within a few minutes. If you still cannot log in after resetting, wait 15 minutes and try again — sometimes the system needs time to update across Citibank's servers.
Two-factor authentication and security codes
Every time you log into your Citibank business account, the system sends a one-time code to your registered phone number (via text) or email address. You must enter this code on the screen after you type your password. This second step is mandatory and cannot be skipped.
If you do not receive the code within two minutes, click "Resend code" on the login page. If you still do not receive it, check that your phone number and email address are current in your account settings. You can update these details by calling the number on your card.
If you are logging in from a new device or location, Citibank may ask additional security questions before sending the code. This is normal and is designed to protect your account from unauthorized access.
Troubleshooting common login problems
If you see a message that your account is locked, it usually means you entered an incorrect password too many times. Citibank locks accounts temporarily for security. Wait 30 minutes and try again, or use the "Forgot username or password?" link to reset your password when ready.
If the website will not load or shows an error message, clear your browser's cache and cookies, then try again. If the problem persists, try a different web browser or device. Citibank's website works best on current versions of Chrome, Firefox, Safari, and Edge.
If you see a message that your account is not found, double-check that you are on citibank.com and that you selected "Business" as your account type. Some users accidentally try to log in through the personal banking section, which will not recognize a business card account.
What you can do once you are logged in
After you log in, you can view your current balance, recent transactions, and statement history. You can also read statements as PDF files, set up automatic payments, and change your password or contact information.
Most Citibank business credit cards allow you to pay your bill online through the same login portal. You can make a one-time payment or set up recurring automatic payments on a date you choose each month. Payments typically post within one business day.
If you manage multiple business credit cards or accounts, you can add them to your login after enrollment. This lets you switch between accounts without logging out and logging back in each time.
Frequently Asked Questions
Is there a mobile app for Citibank business credit card login?
Yes. Citibank offers a mobile app called Citi Mobile for business users. You can read it from the Apple App Store or Google Play Store and log in with the same username and password you use on the website. The app includes the same two-factor authentication requirement.
Can I log in if I am outside the United States?
Yes, but Citibank may flag your login as unusual if you are in a different country than your registered address. You may be asked additional security questions or sent a verification code to confirm it is really you. This is a normal security measure and does not prevent you from logging in.
What should I do if I think someone else logged into my account?
Call the number on the back of your business credit card when ready. A representative can review your recent login activity and lock your account if needed. You can also change your password right away through the "Forgot username or password?" link, which will log out all other sessions.
How do I enroll a second user on my business credit card account?
If your business has multiple cardholders, each person needs their own login. Contact Citibank at the number on your card to add authorized users. Each new user will receive their own enrollment materials and can set up their own username and password.
Can I use the same password for my personal and business Citibank accounts?
Technically yes, but Citibank recommends using different passwords for security. If someone gains access to one account, they would not automatically have access to the other. Personal and business accounts are separate in Citibank's system, so changing one password does not affect the other.
