GREAT LAKES CREDIT UNION

About GREAT LAKES CREDIT UNION

GREAT LAKES CREDIT UNION is a member-owned credit union headquartered in NORTH CHGO, Illinois. As a not-for-profit financial cooperative, it returns earnings to its members in the form of lower loan rates, higher savings yields, and reduced fees rather than distributing profits to outside shareholders. Like all federally insured credit unions, deposits are insured up to $250,000 per share owner by the National Credit Union Share Insurance Fund (NCUSIF), administered by the National Credit Union Administration (NCUA).

The institution participates in the Federal Reserve's FedACH network, which is how routing number 271975951 identifies it for electronic transactions. Members use this number for direct deposit of paychecks and tax refunds, automatic bill pay, ACH transfers between accounts, and most domestic wire transfers. The same number prints on the bottom-left of every check issued by the credit union and appears in member-facing online banking dashboards.

How to use this routing number

For direct deposit of your paycheck, give your employer the routing number above along with your account number. Your employer's payroll provider will then send funds directly into your account on payday — usually one or two days faster than waiting for a paper check to clear.

For tax refunds, enter the routing number and your account number on IRS Form 1040 (line 35b for routing, 35d for account number). The IRS will deposit your refund electronically, typically within 21 days of accepting your return.

For ACH transfers between your GREAT LAKES CREDIT UNION account and accounts at other banks (such as funding a brokerage or savings account), provide the same routing number and account number to the receiving institution. Most ACH transfers settle within 1–3 business days.

For domestic wire transfers, the sending bank uses this routing number to direct funds to GREAT LAKES CREDIT UNION. Some institutions use a separate routing number specifically for wires — if your wire is rejected, contact the credit union to confirm whether a different number applies.
