Kaiser Permanente-Related Employees

Important Action Needed Before 5 pm Friday, March 20

Single Account Number Required as of Monday, March 23, 2026

 

Single Account Number Required Moving Forward

Some current and former Kaiser Permanente employees are using two different account numbers for a single checking or savings account. Since 2015, when HomeStreet Bank acquired Simplicity Bank some account numbers were never converted, and thus, we have been moving transactions from the unchanged, old Simplicity Bank account numbers to the correct HomeStreet account numbers on behalf of our customers.

As of Monday, March 23, 2026, we will no longer be able to move transactions from the old Simplicity Bank account number to the correct account number on your behalf. A single correct account number will be required.

What you need to do:

  1. Confirm your correct Account Number for going forward
  • Impacted clients were sent a hard-copy letter the week of March 16th to the address we have on file for their checking or savings account. The letter includes detailed instructions and a direct deposit form to use with your human resources department to update your account.
    • If you have questions about which account number you need to use moving forward, please contact us at 800.719.8080 before 5 pm Friday, March 20 to avoid disruption to your direct deposits.

  1. Direct Deposits and Automatic Payments
    • If you have direct deposits, automatic withdrawals, or recurring payments tied to your old Simplicity Bank account number, contact your HR department or login to your HR platform to update those with your correct account number as soon as possible. Your Kaiser HR business partner should be able to help you make these necessary changes.
    • To assist you, here is a downloadable Direct Deposit authorization form (link to form)
    • Until March 23, 2026, items presented using your old Simplicity Bank account number will continue to be redirected to your correct account to help ensure a smooth transition.
  2. Checks and Debit Cards
  • You may continue using your existing checks until your current supply runs out
  • Your HomeStreet ATM, Debit and Credit Cards with the Visa® logo will continue to function without interruption until further notice
  • Some customers will receive a new Mechanics Bank ATM or debit card and will be notified in advance.
  1. Online and Mobile Banking
  • Your online and mobile banking access will be migrated to our new Online Banking Plus platform. More information is available here (link to https://www.mechanicsbank.com/transitionhub/new-personal-online-banking-experience/)

We understand that account changes require careful attention, and we are committed to making this transition as seamless as possible. If you have additional questions, please contact us at 800.719.8080 or stop by your local branch.
