We have always enjoyed excellent service at the Noroton Heights P.O. We are now senior citizens who are unable to walk to our mailbox. I there any way our mail carrier could deliver our mail to our front door? Thank you.


There is a serious problem at this location. I have mailed letters here that have never arrived. I have mailed letters that arrived a month later, costing me money in fees. Add to that, they are closed from 11 to noon.... when most of us have time to go to the post office. Avoid this location at all cost.
