Postal Letter

What is the latest that USPS will deliver a package?

Like, I know that the mail comes at the same time everyday.. But is there a certain time that USPS stops delivering for the night, or is it separate? It's 6 pm my time.. Is there a chance the package could still come today, or no? Thanks for the help!

1. 4 PM usually. Your package probably isn't going to arrive today.

3. Most letter carriers are back at their stations before 4 o'clock. Usually the only time they're out very late is during the week of Christmas.
