If it were me, to get the dimension when empty, I would measure the width as you did, the height of the opening which I think is accounted for in the curved top and then the depth of the drawer versus both the depth of the box front to back and the depth from drawer to bottom and come up with some sort of calculation.BoxGuard is a heavy-duty locked box that’s clearly marked so that delivery professionals know where to put products and packages. They could probably come up with a standard max dimension when empty, but if two people put that in before you, getting the pivoting mail drawer may not be able to fully extend if it is already partially full. I would add that part of the issue is what is already in the collection box. (I thought they were pretty standard one size, but who knows.) She guesses that there may be different sizes of blue collection boxes therefore they won't give a size. It can be more than 13oz if using an online postage system rather than stamps. Her specific answer, after speaking with a supervisor, was that if it fits we will take it. You will get what is on the website about 13oz. They either do not have he information or refuse to give it out. posted by enn to Grab Bag (12 answers total) 2 users marked this as a favoriteīest answer: I just got off the phone with the USPS help line (80). I expected this information to be easy to find but I have not had much luck with Google or the USPS web site. I'm aware of the weight limits for stamped packages in drop boxes, but they do not apply to packages with printed labels from services like Endicia, so they are not relevant here. I'm looking for an answer from an authoritative source, not speculation-I can speculate myself.

The maximum width is easy enough to measure and seems to about around 14' but the maximum height and depth are trickier due to the curved top and pivoting mail drawer.īuying one of each of various sizes and trying them is not an option, since the type of boxes I am looking at are generally only sold in bundles of 25 or 50. I am ordering some boxes to use for mailing and although I usually take packages to the post office while it is open, I'd like to order the largest size that will give me the option of using USPS drop boxes after hours.
