USPS Mailing Time Question?

It is almost impossible to have something delivered the same day that you put it into a mail box. Every blue mailbox has (or should have) a sticker on the drop slot that tells you the pickup times. Some boxes are picked up several times a day. Others are picked up only once. At the post office itself, they can tell you - if it is not posted - when mail is collected that you drop into the slot inside the post office itself. However - simply picking it up is only part of the equation. The mail that is collected must be sorted for each destination. If your item is going to a local address, then it will go into the stack of mail for the carrier who delivers on that route. But - that carrier may have _already left_ for their service route. So it makes no difference if your letter gets onto that stack. It will not be delivered that same day. Our mail arrives between 11 am and 2 pm, most days. I don't know when the carrier leaves on their route, but I imagine he is in the truck by 9am. If you were able to drop something into the inside mail drop at my local post office by 8 am, then it is _possible_ but not certain, that I would get it the same day. Otherwise it will come the next day. You could ask at the window what is the latest time you could drop mail at the PO itself for it to get out that same day to a specific address. They are the only ones who might be able to answer that question.
