How to contact FNBO credit card support
FNBO (First National Bank of Omaha) credit card customer service is available by phone, mail, and online through your account portal. The main customer service number for FNBO credit card holders is 1-800-555-5555. This line handles billing questions, fraud reports, payment issues, and account changes. You can also reach support through the FNBO website by logging into your card account and using the find message feature.
Phone support is typically available Monday through Friday during standard business hours, with limited weekend availability depending on your issue type. If you have an urgent matter like fraud or a lost card, FNBO maintains a separate 24/7 line — check the back of your card for the emergency number specific to your account.
For non-urgent matters, mailing a letter to FNBO's customer service department works, though responses take longer. The mailing address appears on your monthly statement and on the FNBO website under "Contact Us."

What information to have ready before calling
When you call FNBO customer service, have your credit card number or the phone number on file with your account. The representative will use one of these to pull up your account. If you are calling about a specific transaction, have the date and amount ready so the agent can locate it quickly.
If your issue involves fraud or a disputed charge, gather any documentation you have — receipts, emails, or screenshots of unauthorized transactions. For billing or payment questions, know your current balance and the date you made your last payment. This speeds up the call and reduces the chance you will need to call back.
If you are calling from a different phone number than the one on your account, have a form of identification ready. FNBO may ask security questions to verify your identity before discussing your account.
Using the online portal for account management
The FNBO website lets you handle many issues without calling. Log into your account at fnbo.com and select "Credit Cards" from the main menu. From there you can view your balance, recent transactions, and payment history. You can also set up automatic payments, update your contact information, and read statements.
The find message feature in your online account is useful for questions that do not require an when ready answer. Send a message describing your issue, and a customer service representative will respond within one to two business days. This avoids hold times and creates a written record of your request.
If you forget your online password, use the "Forgot Password" link on the login page. FNBO will send a reset link to the email address on file. If you no longer have access to that email, call customer service to update it.
Reporting fraud or a lost card
If your FNBO credit card is lost or stolen, call the emergency number on the back of your card when ready — this line is staffed 24 hours a day, 7 days a week. The representative will deactivate your card right away to prevent unauthorized charges. Have your card number ready if you can, but the agent can also look up your account using your Social Security number and date of birth.
For fraudulent charges that appear on your statement, call the main customer service line during business hours or use the find message feature in your online account. Describe each unauthorized transaction with the date and amount. FNBO will investigate and typically respond within 10 business days. While the investigation is underway, you are not responsible for the disputed amount.
Keep records of all communications about fraud — note the date you called, the representative's name, and what was discussed. If you follow up by mail, send a letter to the address on your statement marked "Dispute of Billing Error" and include copies of your documentation.
Payment and billing questions
To make a payment on your FNBO credit card, log into your online account and select "Make a Payment." You can pay from a checking or savings account linked to FNBO, or from an account at another bank. Payments made online typically post within one business day. You can also set up automatic monthly payments so you never miss a due date.
If you are unsure about a charge on your statement, call customer service with the transaction date and amount. The representative can tell you the merchant name and what the charge was for. If you still believe it is an error, they can start a dispute investigation at that time.
For questions about your interest rate, credit limit, or fees, customer service can explain what you are being charged and why. If you have been a customer in good standing, you can ask about a rate reduction or fee waiver — the representative cannot always grant one, but they can note your request and pass it to the account review team.
Mailing address and written correspondence
If you prefer to write to FNBO, the mailing address for credit card customer service appears on your monthly statement under "Questions?" or "Contact Us." Mail your letter to that address, and include your account number, name, and a clear description of your issue.
For billing disputes, write "Dispute of Billing Error" at the top of your letter. Include the transaction date, amount, and merchant name. Send the letter by regular mail or certified mail if you want proof of delivery. FNBO must respond to written disputes within 30 days.
Written correspondence takes longer than a phone call — typically 7 to 10 business days for a response. Use this method for issues you have already discussed by phone and want documented in writing, or for formal disputes that require a paper trail.
