My father worked at this post office for 35 years and he loved it. Maby some of you guys know him. His name is Paul Crago. When my kids were little they used to play in the back and on the loading dock. Everyone was so nice there.


As a none resident of Raritan I always go out of my way to buy my stamps and ship my several priority packages twice a month. It's clean, professional, yet small town feeling all at the same time keeps me coming back. Thanks




The Raritan NJ Post Office is the Post Office from Hell. The my regular carrier supposedly went out on sick leave and his replacement regularly places the mail in the wrong mailboxes. I did not recieve utility bills, credit card bills, Government tax information (NJ W-3 and Annual Report for my company) and missing 1099. Two checks mailed to me totalling $18,500 were delivered to my neighbor's house! This post office is ridiculous!!!! I am ready to call the police! Avoid this post office at all costs!!!


I had a small amount of those problems back then also. I did some research and found out the regular Post Master at the time was on assignment. So, I'm guessing the interim PM was just that - interim. The post master that's there now is the one who does a good job keeping us Raritan dwellers happy. I've seen her actually carrying mail in the rain last week. Then to come back and run the PO is pretty cool.
