There is a severely mentally ill individual that has been working in the Idaho Falls USPS location on 4th street the past few years. Whoever they are is somebody that knew me in high school and attended Idaho Falls High School with me in the early 1990’s. They are guilty of federal crimes in relation to my mail. They have crossed my name out and put my first name on my mail instead of my middle name that the letter was sent to. They have returned much of my mail that I had to have delivered at other locations. They have had junk mail sent in the name of one of my girlfriends in high school. This individual will be in their mid to late 40’s and would have attended Idaho Falls High school. They are exceedingly deranged but may fit in and be hiding their illness well. If anybody you know that fit this description be wary of them as they have a serious derangement of heart and mind. They are sociopaths and close to a state of psychopathy. Watch them as they have no conscience and are not fearful of committing federal felonies and misdemeanors.


Idaho Falls 4th Street Post Office 8340I know you're stretched thinner in athe Bonnbooming economy. You've been here every day for Stonehaven area by Hillcrest. I received the postcard about mail in voting and a check list. Greatly appreciated! ps: please help me forward this to my local PO. thank you


ABOUT 10:30 a.m. I started to check the delivery schedule today ACCORDING to the delivery log, my package was delivered to my porch step at 11:04 a.m. this morning. It wasn"t there. I waited for my regular mailman as of nine oclock this evening he hasn't come by. (I sent an e-mail to the company who shipped it and it must of been closed too, as I have heard nothing. I live at 1481 S Woodruff Ave. Can you assist me with this matter ? 208-244-1914.


I had a certified letter sent to myself and I wasent home to receive it is there anyway I could com to the post office and collect it please david pierson


Wanting to know if mail has been delivered to 550 West 21st Idaho falls, Idaho 83402


Why are these mail people required to work till 7/8 o’clock at night to deliver the mail each day? It’s freezing cold outside and snowing and these poor deliverers come Trudging down the street! Do you need to hire more mail deliverers?? Looks like cruel and usual punishment to me!


Please explain why a postal carrier is not obligate to pick up post when delivering mail to a mailbox? Twice in the last three days mail was left but mail was not picked up. Not what I would call stellar service.


The Post Office located at 605 4th Street DOES NOT accept General Delivery. The Post Office located at 875 N. Captial DOES accept General Delivery. Please update your website....


I like to know why I did not get my check in the mail ????? The is the second time has happened to me . I get it in the mail every 2 weeks!!!!!


I had mailed my taxes in a neighborhood mailbox two days ago. A very kind neighbor just delivered my State Tax envelope to me. Said he found it in the street gutter by his house. I should be able to trust that the items that I mail will arrive safely not end up in a gutter
