I always got exceptional large amount of mail and Rainier oregon always keeps courteous impolite respectful what I've noticed since moving from Portland oregon.


This Post office is under employed and will not deliver packages just saying "attempted delivery" when delivery was NOT even attempted. Mail box is usually big enough to hold packages and when not able they don't even attempt to drop it off at the house. Phones are almost never working, and a worker told me that they don't even answer the phones because there's so many people calling. THIS IS REDICULUS!


I don't know what to make of this post office. Sometimes I go 2 days with no mail at all, even though I have packages that the USPS says will be delivered during those days. I call the Rainier phone number and nobody will answer the phone. I have a mailbox in town at my house and the delivery person is very nice and seems proficient at her job. I think the problem is at the post office. This post office needs fixed, it is currently broken.


We had a problem with the mail lady giving us some important mail. So we simplified things by ending our po box and just using our mail box which we have had for years. Now instead of finally recieving the article of mail we were expecting..we have had o mail for the last week. Take what we give you and dont complain or you get nothing . This post office needs some cleaning out I believe


Something weird is going on in this office. I send my parents packages from Amazon and they keep disappearing once they've been delivered to this office. I won't trust my packages being delivered here, going to find a UPS store from now on.
