How to insert postal barcode in return address?

Does anyone know how to do this? I am only able to include the postal
barcode in the delivery address via Tools, Envelopes & Labels, Options.

Why would you want to do that?
The USPS mail automation system doesn't need or want you to display a Zip+4
barcode on the from address.
AFAIK, what you want to do cannot be done (and should not be done).
