Support Hub

Interactive Brokers provides multiple support channels including phone support at +1-203-618-5800, live chat available through Client Portal during market hours, the secure message center for account-specific inquiries, a searchable knowledge base with articles and tutorials, video guides covering platform features and trading concepts, and regional phone numbers for clients outside the United States. Phone support is available during extended US market hours with regional offices providing coverage across North American, European, and Asia-Pacific time zones. The secure message center within Client Portal is the recommended channel for inquiries requiring account verification, as messages are encrypted and associated with your authenticated account session. Interactive Brokers also maintains active support through the IBot virtual assistant integrated into TWS, Client Portal, and the mobile app, which can answer questions about platform features, retrieve account information, and provide market data on demand.

The Interactive Brokers knowledge base is accessible through the Client Portal after logging into your IBKR account. It contains thousands of articles covering account management, trading platform operation, order types, margin calculations, API programming, regulatory topics, and troubleshooting guides. The knowledge base search function supports natural language queries and provides ranked results based on relevance. Many articles include step-by-step instructions with screenshots, and video tutorials are embedded where visual demonstration adds value. Interactive Brokers continuously updates the knowledge base with new content reflecting platform changes, new features, and common client inquiries. The knowledge base is also accessible through the IBot assistant in TWS and mobile — simply type or speak your question and IBot retrieves relevant articles. For clients who prefer offline reference, many knowledge base articles can be printed or saved as PDF documents from within Client Portal, making them accessible even without an active internet connection after download.

Interactive Brokers phone support operates during extended market hours designed to cover trading sessions across major global time zones. US-based phone support at +1-203-618-5800 is generally available Monday through Friday from approximately 8:00 AM to 8:00 PM Eastern Time, covering the full US market session plus pre-market and after-hours trading periods. European support centers operate during Central European Time business hours and London market hours. Asia-Pacific support is available during Hong Kong, Singapore, and Tokyo market hours. Exact hours may vary by department and region. For the most current schedule, check the contact information within Client Portal. Phone support handles account inquiries, trading assistance, platform technical support, and general questions. For complex issues requiring documentation review, the secure message center may be a more effective channel as it allows support staff to attach reference materials and maintain a written record of the resolution process that both the client and Interactive Brokers can reference in future interactions.

The secure message center is an encrypted messaging system integrated into the Interactive Brokers Client Portal. After logging in, navigate to the message center to compose new inquiries, view responses from IBKR support teams, and track the status of open tickets. Messages sent through this system are transmitted over the same TLS-encrypted connection used for all Client Portal traffic and are associated with your authenticated account, eliminating the need for separate identity verification. The message center supports file attachments for submitting documents such as account applications, tax forms, and wire instructions. When you create a new inquiry, you select the relevant department — account services, trading support, technical assistance, funding, or compliance — to ensure routing to the appropriate team. Interactive Brokers typically responds to secure messages within one business day, with priority handling for time-sensitive trading issues. The message center maintains a complete history of your support interactions, accessible at any time through Client Portal.

For common platform issues, Interactive Brokers recommends a structured troubleshooting approach. First, check your internet connection and verify that Interactive Brokers services are operational — the System Status page within Client Portal displays real-time platform availability. If Trader Workstation fails to launch, try restarting the application and ensuring your operating system meets the minimum requirements. For login problems, verify that your IB Key is properly configured and that the time on your mobile device is synchronized correctly, as time drift can cause authentication failures. If market data is delayed or unavailable, confirm your market data subscriptions are active in Account Management. For persistent issues, clear the browser cache if using Client Portal, or reset TWS settings to default if the desktop platform behaves unexpectedly. The knowledge base contains detailed troubleshooting articles for specific error codes and symptoms. If self-help steps do not resolve the issue, contact Interactive Brokers support through the secure message center with details about your platform version, operating system, and the specific error encountered. For urgent trading issues during market hours, phone support can provide immediate assistance. The National Institute of Standards and Technology at nist.gov provides general guidance on computer security practices that may help secure your trading environment.
