Every time I go here there is a huge line and only one or two people working who are usually rude. I asked if there were more priority leg boxes and employee stated I don't know! I think she forgot she works there no wonder people rather use alternative options for mailing. Customer service is horrible!!!!!!!!!!


Impossible to reach the Boulder Post Office by phone!!!! Called 303-938-3704 12 times during working hours. No answer!!!!!!!!!!!!!!!!!


We have a new postal carrier serving the 400 and 500 blocks of Marine Street. We really like her and we all would like her to be permanently stationed so she can continue to serve our neighborhood. Please put her on permanent appointment.


i have to apply for my son passport his father passed away and I don't have the death certificate since we are not maried. I ask his mom for the death certificate but I don't know if she will give it to me or not.


They haven't answered this phone number, I've called many many times in the last 2 weeks.
