Pay Online Pay with an Electronic Check
         
Another convenient way to pay your Ameren bill online is to pay by electronic check. (Requires log in with UserID and Password.)
  
Paying with an electronic check is similar to a paper check transaction but without the paper. You pay directly from your checking account, and it's processed through the system banks use for electronic deposits and payments. It's safe, easy and free!
  
              
 
Please note: Be sure to have your Ameren bill, checking account and routing number.
