USPS requires a Mail Stop Code (MSC) in a recipient address to be entered before the Attention and Delivery address lines. To satisfy this requirement, you must enter the Mail Stop number in the Name field in SendPro Online.
12 E Main Ave Suite 209
Kryton TN 38188
Due to the address formatting limitation in SendPro Online, you are limited to just the Company field to address the person and/or business that the mail piece or package is being sent to.
