I ordered a ph from eBay it’s showing that it here so can I pick up it because I need it urgently

Generally, you must wait until the day AFTER your local mail carrier has made an attempt before you can pick it up at your post office.

Unfortunately you cannot, this is just a sort facility. No customer service here like at a regular Post Office.

Go to your post office and inquire within or call up first.

Generally no. You have to wait for delivery. You might call 1-800-ask usps to explore any possibilities
