Proseries will not accept the BOA routing #. How do I fix it?

I tested it on a dummy file and it worked

are you sure you didn't key it in incorrectly - maybe add an extra zero?

Isn't it now called BOM, "Bank of Mexico?"

I tried it and it did not work.  Maybe double check with your client?  I googled routing numbers for BOA and that was not an option.  

Savings account vs checking account?

Or did the routing number come from a deposit slip instead of a check?

I've found there can be differences...

BOA took over another bank and client never got new checks - Tell client to get the new routing number

State-Specific or Legacy Routing Numbers

Although Truist leans on a single routing number (061000104) for most activities, some accounts still use older codes from BB&T. These codes vary based on the state where the account originated. For instance:

• Florida: 263191387

• North Carolina: 053101121

• Virginia: 051404260

It’s a good idea to confirm your exact routing number if your account dates back to BB&T. You can contact Truist support or refer to account documentation if you suspect a state-specific number still applies.

This danged keyboard has the capital O way too close to the zero.
