If you're looking for the Chase routing number and account number in Illinois, here's the direct answer: Chase Bank uses different routing numbers depending on when and where you opened your account, but the most common Chase routing number for Illinois is 071000013. Your specific account number is unique to your account and can be found on your checks, in your Chase online banking profile, or on your bank statements.
Understanding Chase routing and account numbers
The routing number is a nine-digit code that identifies your bank and region, while your account number is unique to your personal or business account. Chase, one of the largest banks in the United States, assigns routing numbers based on geographic regions, including Illinois. As of 2025, JPMorgan Chase reported serving over 66 million U.S. households, making routing accuracy essential for millions of daily transactions.
Your account number is tied directly to your individual account and is used for deposits, withdrawals, and transfers. Unlike routing numbers, which are shared by many customers in a region, account numbers are strictly unique and confidential. According to banking security data from 2024, over 78% of fraud cases involved compromised account numbers rather than routing numbers, highlighting the importance of keeping this information secure.
Chase routing numbers for Illinois
Chase assigns routing numbers based on the state where your account was opened, not necessarily where you currently live. Illinois customers typically use one primary routing number, but exceptions can occur depending on account type or legacy bank mergers.
| State | Primary Routing Number | Transaction Type | Notes |
|---|---|---|---|
| Illinois (IL) | 071000013 | ACH transfers, direct deposits | Most common for personal accounts |
| Illinois (IL) | 021000021 | Wire transfers (domestic) | Used for incoming wires |
| Illinois (IL) | CHASUS33 | International wires (SWIFT code) | Required for overseas transfers |
This routing number table reflects the most commonly used identifiers as of early 2026. Always verify your routing number before initiating large transfers, especially for wire transactions where errors can cause delays or fees.
Where to find your Chase account number
Your account number location depends on how you access your banking information. Chase provides several convenient ways to retrieve it securely without contacting customer service.
- On a paper check: The account number appears between the routing number and check number at the bottom.
- Chase mobile app: Log in and select your account to view details.
- Online banking: Navigate to "Account Details" after logging in.
- Monthly statements: Printed or PDF statements display your full account number.
- Customer support: Available 24/7 for verification assistance.
This account retrieval method ensures that customers can access their banking details securely without exposing sensitive data unnecessarily.
How to read a Chase check
Understanding how to read your check helps prevent errors when setting up payments or direct deposits. Chase checks follow a standard U.S. banking format established by the American Bankers Association.
- The first nine digits represent the routing number.
- The next series of digits is your account number.
- The final digits indicate the specific check number.
This check format structure has remained largely unchanged since the 1960s, ensuring consistency across all U.S. financial institutions.
Why routing numbers matter for Illinois customers
The Illinois banking system relies heavily on routing numbers to process millions of transactions daily. According to Federal Reserve data from 2025, ACH payments alone accounted for over 31 billion transactions annually, with regional routing numbers ensuring funds reach the correct financial institution efficiently.
Routing numbers are essential for:
- Direct deposits from employers or government benefits
- Automatic bill payments
- Wire transfers and international transactions
- Peer-to-peer payment setups
This transaction processing role makes routing numbers a foundational element of modern banking infrastructure.
Security considerations for account and routing numbers
While routing numbers are publicly accessible, your account number security should be treated with caution. Financial institutions like Chase have implemented multi-factor authentication and encryption protocols, especially after a 2023 report showed a 15% increase in digital banking fraud attempts.
"Customers should never share full account details over unsecured channels," said a Chase spokesperson in a March 2025 consumer advisory. "Even partial exposure can increase fraud risk."
This security advisory guidance reinforces the importance of safeguarding sensitive banking information.
Differences between ACH and wire routing numbers
Chase uses different routing numbers depending on the transaction type. This distinction is crucial for avoiding failed transfers or delays.
- ACH routing number: Used for direct deposits, payroll, and recurring payments.
- Wire routing number: Used for same-day domestic transfers.
- SWIFT code: Used for international wire transfers.
This routing type distinction helps ensure that funds are processed through the correct financial network.
Common mistakes to avoid
Many users encounter issues due to simple errors when entering banking details. Avoiding these mistakes can save time and prevent transaction failures.
- Using the wrong routing number for wire transfers
- Confusing account number with check number
- Entering outdated routing numbers after moving states
- Sharing sensitive details over unsecured email or messaging platforms
This error prevention strategy is especially important for first-time users setting up direct deposit or online payments.
