A smiling, anthropomorphized phone give a thumbs up!



On Saturday–Monday, November 2–4, Coast Central will upgrade our core computer system to create more efficiency to serve you better and faster. Please read the important information below to help you plan ahead for Upgrade Weekend.

Closure Information

For our System Upgrade, we will close Friday, 11/1, at 6 pm until Tuesday, 11/5, at 9:30 am (10 am for Bayshore).

  • All 11 Member Services Branches, as well as our Member Support Center (our main phone line team), will be CLOSED.
       Note: This means an early close on 11/1 at 6 pm for our Bayshore Mall and McKinleyville locations.
  • Online and Mobile Banking, including bill pay and transfers, and Telephone Banking will be UNAVAILABLE. Note: scheduled and recurring transfers will still occur, but may be delayed.
  • ATMs will function normally for cash withdrawals, but balance inquiries will be UNAVAILABLE.

For Spanish speaking members, consulte nuestra información de actualización del sistema en español.

For more information on our normal hours and holiday closure dates, please visit our Locations & ATMs page.

Why is the upgrade necessary?

Like the software on your computer or cell phone, our computer system has periodically needed updates. After years of updates, the time had come to take advantage of significant improvements in technology and perform a complete upgrade. The new system will allow us to keep pace with your financial needs now and in the future.

What’s NOT changing with the upgrade?

  • Security of your personal and financial information
  • Transaction history access on all channels
  • Member number *
  • Debit and credit cards (and PINs). There should be minimal interruption in usage at ATMs and merchants
  • Checks. You will not need to order a new supply, and they will clear as normal.
  • Direct Deposit/ACH/Payroll Deduction
  • Pre-authorized transactions
  • Wire transfers

Will Online and Mobile Banking access be affected?

Yes, positively. You’ll be able to view all of your accounts through one login and have real-time information updates. After the upgrade, many members, including those who are Primary on joint accounts, will not have to re-enroll. You will only need to re-authenticate (have a one-time security code sent to your mobile device or email) when prompted.

Are my Joint account holders affected?

Yes, all Joint members will need to re-enroll in Online and Mobile Banking, using a different user name than the Primary.

* Will there be any change to my account or loan types?

Yes, though your member number will not change, account type suffixes will have a new format. For example:

  • Membership Savings account 12345 S1 will change to 12345 0100
  • A personal loan 678910 L10 will change to 678910 1000
  • For a full list, please see our Account Type Information sheet.

Mortgage Members

Your mortgage information will now be included with your month-end comprehensive statement that includes your other CCCU deposit and loan account information. Also, you’ll be able to set these up as secure e-statements through Online Banking, saving time and paper.


Be Prepared

  • NOW: make sure we have your current contact info and that of your joint account holders
  • 1 week prior: get some cash, have a couple of payment options, and ensure your online payments and transfers are scheduled
  • 1 day prior: Review your balances. Track your weekend spending to avoid overdrafts
  • After Tuesday, 11/5: Confirm that your online payments and transfers occurred, and Online Banking joint members must re-enroll


If you have questions, please call our Member Support Center at (707) 445-8801 or stop by one of our convenient locations.

  We thank you for your patience and cooperation during this necessary and beneficial transition.
