Use the "Find BC" feature to avoid having to type in the whole 18 digit 1Z. You have to be in the stop to use this feature. Simply hit the scan button, hit Find BC, and then type in the last 4 digits on the 1Z either off the pkg or off the PAL, which may be easier as the font on the last 4 is bigger and easier to read. You may have two or more to choose from so you will have to double-check the label to make sure you select the correct 1Z. It may sound confusing but is much easier after you do it for awhile and it is much quicker than typing in the the whole 1Z. If the pkg has not been through EDD then you will have to type in the whole 1Z.
There has been a lot of information and disinformation given regarding sheeting ASD's that do not have the shipper number. The correct way is to use the first six letters of the shipper name (company) or, if that is not available, use the first six letters of the last name of the person sending the pkg. Of course, if there is a BIN #, use that--it is much longer than a shipper number and stands for Billing Identification Number and is used for those shippers that do not have a shipper number. If there is absolutely nothing in the shipper field, use "ASDASD" and then fill in the weight, L for letter and a number for a numerical weight. This is also the place to do weight corrections as shippers are billed off of the data entered by the driver if there is a conflict between the billing copy and the data entered at delivery (ASD says L while the actual weight is 5, you would enter 5 and a billing adjustment would be made internally.
