If you need help with an IBC Bank checking or savings account, debit card, unauthorized transaction, online banking, mortgage, credit card, deposit, transfer or branch problem, use the support route for your IBC market and account type. IBC Bank does not currently publish one nationwide general customer-service number; customers are directed to regional main offices and issue-specific support lines.

IBC Bank is part of International Bancshares Corporation, a Laredo, Texas-based financial holding company serving communities in Texas and Oklahoma. IBC provides personal, business, international and mortgage banking services and is a Member FDIC.

IBC Bank Fraud and Account Security

Never give an unexpected caller or text sender your online banking password, debit-card PIN, complete card number, Social Security number or Secure Access Code. Do not follow a banking-login link from an unsolicited email or text.

If you notice unauthorized debit-card activity, call 1-866-902-5860, Option 4, immediately. The separate 1-800-894-6076 fraud hotline is for suspected bank fraud and ethics or conduct violations; IBC specifically says it is not a normal customer-service or complaint line.

IBC Bank Main Office Phone Numbers by City

IBC Bank routes many routine account questions through the main office serving the customer’s geographic market.

Use IBC’s current branch locator for individual branch numbers and hours. Branch schedules vary, and many IBC locations offer extended or weekend banking hours.

IBC Bank Lost or Stolen Debit Cards

Report a lost or stolen debit or ATM card immediately. IBC currently publishes different numbers depending on the type of card.

If you still have the card but notice an unauthorized debit-card transaction, call the personal debit-card number and select Option 4.

Review recent account activity and identify every transaction you do not recognize. Keep dates, amounts, merchant descriptions and any prior communication with the merchant.

IBC Bank Unauthorized Transactions and Identity Theft

If you believe someone gained unauthorized access to your account, contact IBC promptly rather than waiting to see whether additional transactions appear.

IBC’s current fraud-prevention guidance tells victims of identity theft or account fraud to contact their IBC customer-service representative immediately. The bank says it will work with customers regarding unauthorized transactions and incorrect information that may have been reported to credit bureaus.

Depending on the situation, consider:

  1. Reporting the compromised debit card.
  2. Changing online banking credentials through an official IBC channel.
  3. Reviewing recent statements and transactions.
  4. Documenting every unauthorized transaction.
  5. Asking IBC for the claim or case information.
  6. Following any written dispute instructions supplied by the bank.

Do not publish fraud-claim documents or transaction details containing account numbers in the CSN review section.

IBC Bank Fraud Hotline

IBC maintains an anonymous fraud and Code of Ethics and Business Conduct hotline at 1-800-894-6076.

This hotline is intended to report possible bank fraud, misconduct and violations of banking-related ethics or regulations. IBC specifically states that this number is not a normal customer-service or complaint line.

Ordinary issues involving a fee, deposit, debit-card dispute, online banking problem or branch complaint should begin with the appropriate IBC customer-service representative or branch.

IBC Bank Online and Mobile Banking Support

For online or mobile banking problems, IBC’s current Personal FAQ publishes 210-841-3000.

Current support hours are:

  • Monday-Friday: 8:30 a.m.-5:30 p.m.
  • Saturday: 8:30 a.m.-1:00 p.m.
  • Sunday and holidays: Closed

Online Banking Support can help with issues involving:

  • User ID or password problems
  • Locked online banking access
  • Secure Access Codes
  • Outdated telephone or contact information
  • Mobile banking access
  • Device registration

IBC Bank Online itself is generally available 24 hours a day, seven days a week, except for maintenance periods and outages.

IBC Secure Access Code Problems

IBC uses Secure Access Codes as part of its online banking authentication process.

If the telephone number or other contact information displayed for your Secure Access Code is no longer correct, IBC says you may be unable to complete the login process. Call Online Banking Support at 210-841-3000 so the bank can verify your identity and assist.

Never provide a Secure Access Code to someone who unexpectedly calls, texts or emails claiming to be from the bank.

IBC Voice Telephone Banking

IBC Voice is the bank’s automated telephone banking system. It provides 24-hour access to certain account information using an IBC Voice PIN.

IBC uses different Voice numbers by city, so use the current IBC Contact Us page to find the number for your market.

IBC’s online banking terms also direct customers seeking certain Online Banking Customer Service functions to call their local IBC Voice number and select Option 7.

IBC Bank Credit Card Customer Service

For an existing IBC credit card, the safest route is the telephone number printed on the back of the card because servicing information can vary by card and issue date.

IBC’s current lost/stolen-card information lists:

Credit cards issued after June 2017: 1-800-444-6938

Report a lost or stolen credit card immediately. Do not wait for an unauthorized transaction to appear.

IBC Mortgage Customer Service

IBC Mortgage publishes a separate support number for home-loan questions:

IBC warns that ordinary email is not secure and should not be used to send passwords, account numbers, Social Security numbers or other sensitive information.

For existing mortgage servicing, IBC currently publishes:

IBC Bank Routing Numbers

IBC does not use one routing number for every market. The routing number depends on the banking charter and location.

Current examples published by IBC include:

  • Laredo: 114902528
  • Commerce Bank – Laredo: 114909903
  • Zapata: 114912709
  • Eagle Pass: 114902612
  • San Antonio: 114013284
  • Houston: 113000861
  • Port Lavaca: 113105025
  • Austin: 114902528
  • Brownsville: 114911580
  • Corpus Christi: 114912275
  • McAllen: 114917623
  • IBC Oklahoma: 303072793

Verify the routing number through IBC before initiating an important ACH or wire transaction. Do not rely on a routing number from another IBC market simply because the bank name is the same.

IBC Bank Branch Complaints

For a problem involving a specific teller, deposit, account opening, branch transaction or local service issue, start with that branch and ask for a manager when necessary.

Document:

  • Branch location
  • Date and approximate time
  • Transaction or service requested
  • Representative or manager contacted
  • Explanation provided by the bank
  • Specific resolution requested

Some matters involving fraud, card disputes, account restrictions or compliance decisions may need to be handled by another IBC department rather than the local branch.

How to Escalate an Unresolved IBC Bank Complaint

  1. Contact the branch or department responsible for the problem.
  2. Clearly explain the transaction, fee, account restriction, fraud claim or other issue.
  3. State the resolution you are requesting.
  4. Ask for a case, claim or reference number when available.
  5. Keep statements, receipts, letters and secure messages.
  6. Request review by a branch manager or appropriate supervisor if the first contact does not resolve the problem.
  7. Ask for important decisions or explanations in writing.
  8. If a Texas banking complaint remains unresolved, review the applicable Texas Department of Banking complaint process.

IBC’s own regulatory-disclosure page states that International Bank of Commerce is a Texas state-chartered bank subject to regulatory oversight by the Texas Department of Banking.

The Texas Department of Banking currently accepts complaints involving supervised Texas state-chartered banks and publishes:

Contact IBC first when possible and keep copies rather than originals of supporting records. Regulatory complaint procedures are not a substitute for reporting a lost card or active fraud immediately.
