Provide your account information to the companies/organizations that currently make any automated deposits or withdrawals to your account.  Examples could include payroll, Social Security, health club membership, insurance premiums or IRS refunds/payments.  Review your recent Jeffco statements to assist in identifying your automated transactions.  All current automated transactions will continue as scheduled; but, it is important to make these changes to avoid any interruption of automated transactions in the future.  Any future automated transactions should be set up using your new account number and the Westerra routing number. 

Jeffco Public Schools Payroll and PERA Benefits – There is no need to re-establish direct deposits and pre-authorized withdrawals with Jeffco Public Schools or PERA at this time.  We are currently working with both organizations to attempt to have all your new account information updated automatically. We will provide updates in the future should you need to make any changes.
