It is important to have your name and new address written on each box, especially for long distance moves. It might be difficult to do given huge number of boxes you might have. But in case one of your boxes is lost in the process it would be much easier for the moving company to find and mail it to your new address.
When packing use red marker to indicate FRAGILE on delicates, and THIS END UP where appropriate. Make sure those notes are clearly visible and written on each side of the box. More information on packing and shipping here.
When packing make a master list of all household items and your belongings. You can also number the boxes, but make sure you don’t confuse those numbers with the numbers of rooms already written on your boxes.
When everything is packed and ready to load, make sure the items you need least are loaded first.
