Why SIUE CREDIT UNION May Have Multiple Routing Numbers in IL

Large US banks like SIUE CREDIT UNION historically assigned routing numbers by Federal Reserve processing centre rather than purely by state. As a result, SIUE CREDIT UNION may have different routing numbers for different cities or regions within IL. Your routing number depends on which Federal Reserve office processed accounts when your branch was established — not necessarily your current ZIP code. This is why selecting your specific city is important when looking up the correct SIUE CREDIT UNION routing number in IL.

When You Need the SIUE CREDIT UNION IL Routing Number

Direct Deposit Setup

When setting up payroll direct deposit, IRS tax refunds, Social Security benefits, or any government payment to your SIUE CREDIT UNION account in IL, you provide the routing number alongside your account number. Use the city-specific routing number from BankZop — the one assigned to the location where your SIUE CREDIT UNION account was originally opened.

ACH Transfers and Bill Payments

ACH is the primary mechanism for electronic payments in the US — covering recurring bill payments, subscription debits, online banking transfers, and same-day payments. The NACHA network uses the routing number to route credits and debits to the correct financial institution. Standard ACH settles in 1–2 business days; Same Day ACH settles same-day for eligible transactions submitted before the cut-off.

Domestic Wire Transfers

Domestic wires settle in real time through the Federal Reserve's Fedwire system on the same business day. Important: SIUE CREDIT UNION may use a different routing number for wires than for ACH. Always confirm the correct wire routing number with SIUE CREDIT UNION's wire department before initiating a wire transfer from a IL account. For international wires, a SWIFT/BIC code is required — not the routing number. Find it at BankZop's SWIFT Code Lookup.
