Star One Credit Union Routing Number: Silicon Valley Banking Guide

What is the Star One Credit Union routing number?

Star One Credit Union uses routing number 321177968 for ACH transfers, direct deposits, and electronic payments. This routing number identifies Star One within the Federal Reserve system and is the same for all members regardless of account type.

Star One Credit Union is headquartered in Sunnyvale, California, and primarily serves employees and contractors of major Silicon Valley technology companies, including Apple and Lockheed Martin. With over $10 billion in assets, it is one of the largest credit unions in Northern California.

How to find your Star One routing number

The easiest way to find your Star One routing number is through the credit union's mobile app or online banking portal. Navigate to your account details and the routing number will be displayed alongside your account number.

You can also find the routing number printed on the bottom-left corner of any Star One check. If you do not have checks, member services can provide the number over the phone or at any branch location.

Star One direct deposit and payroll

To enroll in direct deposit at Star One, share routing number 321177968 and your account number with your employer or payroll provider. Many Silicon Valley employers already have Star One in their payroll systems, simplifying the setup process.

Star One also supports split deposits, allowing you to route a portion of your paycheck into savings or a secondary account automatically each pay period.

Star One wire transfers and international payments

Star One processes domestic wire transfers through the Fedwire system. Outgoing domestic wires initiated before the daily cutoff are typically received the same business day. Contact Star One for the specific wire routing number, as it may differ from the ACH routing number.

For international wires, Star One uses correspondent banking relationships to facilitate transfers. International wire fees and exchange rates vary, so members should confirm costs with the credit union before sending funds abroad.
