The "The account number specified does not have the correct number structure" error means the bank account number entered is not formatted correctly — it likely has the wrong number of digits or fails a check digit validation.
How to Fix It
Have the tenant double-check their bank account number and re-enter it carefully. Common mistakes include:
Entering the routing number instead of the account number
Missing or extra digits
Copying from a check incorrectly (account number is the second set of numbers on a check, after the routing number)
