Kudos to all those who stand behind the counter at the Los Alamitos Post Office and deal with the the public 7 days a week. In this very clean and orderly place the assistants are always friendly, helpful and fast! I appreciate having a post office like this handle all my mailing needs. Thank you. E.P.


I would like to praise the Los Alamitos post office for our mailman in Rossmoor by the name of Miller. He is focused, efficient, dependable and has a good sense of customer service. No mistakes made ever. Please pass this on to the right people at the post office in Los Alamitos.


I just received a card from the mail man stating to keep my dog inside. She never gets out. She is a 6 inch tall terrier that barks alot. No we wont ask for mail when she is around. But unless the Carrier wants to tell me exactly what time he is coming I am not putting her in a locked room. She is inside anyway. She is not near the mail box. I do not understand what prompt him to leave this card.


I had sold some items online this past weekend and purchased labels with tracking. I weighed the packages and rounded up to the next ounce. A few were pre printed labels for 8 ounces and the actual weight of the package was 2 ounces. I printed out the labels and securely taped them to the padded envelopes, not covering any of the bar code. I dropped them off on Monday 4/13/2020 and I still have not seen any scans of these packages days later. Now I stand to lose all of my money and the sewing elastic that I had shipped out.


Vacation hold has been perfect until the last two times. I was supposed to receive my mail today but have not again!


The Los Alamitos post office provides the worst customer service ever! They have a drive thru to drop off your mail, but every mail box in the drive thru has duct tape on it saying "OUT OF ORDER". How can a mail box be out of order?? Just unbelievable!!


I have given Los Alamitos post office several opportunities to deliver my parcels correctly as to not leave them in an unsecured area at my residence if no one is home yet they continue to leave them there and they keep getting stolen! I've placed several notices on my door stating please do not leave packages at my front door for they are being stolen yet the postal carriers continuously disregard said notices, I went to the post office personally to leave notice for the carrier's not to leave packages at my door yet my requests have been ignored!
