While it may be possible to remove the second address field and put all the information in address line 1, it is not recommended. The second address field is typically used for apartment numbers, suite numbers, or other additional information. Putting all this information in Address Line 1 can make the address challenging to read and may cause problems when the information is being processed. In addition, some addresses may not fit in the available space if all the information is put in address line 1. For these reasons, leaving the second address field intact is best.
