My postal box is located off premises and I am disabled. A key was in my box labeled with the letter P. My driver looked and did not locate a box with this letter. Did he over look it or could this mean that I have mail requiring a signature or identification at my local post office. 571 S. Union St. #202 Gary, IN 46403. Thank you. Karen Champion


I have received NO mail since last Thursday. I am concerned that mail that NEEDS to get to me is NOT being delivered. Please advise!


I'm still here on Saturday at 10:47. My post office is out here because I used to work out here. And it's still closed! No signs no nothing. This is ridiculous I'm supposed to be picking up packages


It is now 8:17 am on Saturday and the Post ofc isn't open. I have had an occasion to need to stop at Post ofc. often at 8 am recently and never open at 8. Some times as late as 30 minutes late. Why???


How long is it for the mailman to come on my block
