STCU Routing Number in Washington

STCU has one routing number registered in Washington. When setting up direct deposit, bill pay, or wire transfers, make sure to use the routing number assigned to your specific branch or account — using the wrong one can delay or reject your transaction.

Your routing number appears on the bottom-left of any STCU check, in the STCU mobile app under account details, or by calling STCU at 800-858-3750. For ACH transfers like direct deposits and bill payments, use your state-specific routing number. For domestic wire transfers, STCU may use a different number — always confirm with the bank before sending a wire.
