If you are getting this error, it means that the shipping address provided contains more characters than what is allowed for the Address Line 1 or Address Line 2 fields. Please reduce the number of characters used and resubmit the order.
Typically, you can either break the address into 2 separate lines using both Address Line 1 and Address Line 2 or shorten some elements (e.g. Building -> Bldg, Apartment -> Apt, etc.).
