Frequently Asked Questions

Sound is looking forward to expanding its footprint and serving more members in Snohomish County. This purchase will allow Sound to continue delivering world-class service to its members and build a stronger relationship with the local community. It also provides Sound with more office space to conduct daily business and better serve its northern territory.


Sound is a member-owned financial cooperative that is chartered in the State of Washington and led by a board of directors, elected from the membership. Individuals that live or work in Washington can become members. Members enjoy access to low-cost deposit and loan products, as well as digital services such as online and mobile banking. There is no membership fee to join or remain a member. Individuals become members by maintaining a share account, often referred to as a savings account.

During the account integration (when the First Interstate Lynnwood branch accounts and services transition to Sound), clients that do not already have a savings account will automatically have one opened for them, thereby making former First Interstate depositors’ members of Sound. Look for more information on this as the account integration gets closer.

First Interstate and Sound have applied to the appropriate regulatory agencies for approval. Additionally, both institutions will work together throughout the acquisition. The sale is expected to be finalized in January 2021. Updates will be provided along the way and when the sale is complete.

Once the sale is approved by regulators, an integration date will be finalized. The integration is anticipated to take place by the end of the year. Communication will be sent to First Interstate Lynnwood branch clients throughout the process.

The First Interstate Lynnwood branch team members have been offered positions at Sound. You may see some new faces as we add existing Sound team members to the branch.

At the completion of the sale and account integration, First Interstate Lynnwood branch clients will receive new account numbers for their Sound accounts. You will be notified well in advance of these changes to allow for a smooth transition, and our employees will be available to assist you through this process.

Yes. Sound is insured by the National Credit Union Administration (NCUA) through the National Credit Union Share Insurance Fund (NCUSIF). First Interstate is insured by the Federal Deposit Insurance Corporation (FDIC). Your deposits will continue to be federally insured to the maximum amount available of $250,000 per depositor and backed by the full faith and credit of the United States Government.

Your First Interstate account will become a new account at Sound when the transition occurs, meaning you will have multiple deposit accounts. If you would like to combine the accounts, please contact Sound after the integration is complete. A Sound team member will be happy to assist you with this process.


Yes, some changes will be made to your account. Information will be provided to you prior to account integration, including the changes to your account agreement, terms and conditions, along with rate and fee schedules. Please review and retain these documents for your records.

Until the account integration is completed, you may continue to access your First Interstate account just like you do now. Throughout this process, Sound will send you updated information to help guide you through the integration. Once the integration of accounts is complete, you will have access to your account through Sound’s digital services, contact center, or by visiting a branch.

Yes. Sound serves businesses of various sizes. The credit union serves nearly every industry in Washington and specializes in personalized loan and deposit services.
