Loans and Loan Payments

You can place a stop payment on a lost or stolen check that has not yet been presented for payment by phone or at any branch.

  • By phone: Contact the Member Assistance Center

  • Branch: Stop by any branch location

Stop payments placed through the Member Service Center or at a branch are assessed a fee of $25 per request or $35 for a series of checks.

You will need to provide your 13-digit account number which differs from your member number. A 13-digit number is needed for all automatic clearing house (ACH) transactions. You can find this at the bottom of your checks. From left to right you will see our routing number, a separator symbol, then your 13-digit account number.


Automatic Loan Payments allow regular payments on a Mainstreet loan to be transferred from your checking or savings account. To set up automatic payments, call the Member Assistance Center or stop by any branch location.
