We have not had mail delivery for two days on Saville Street in Cambridge, MA. We are worried about our mail person, Harj. Please see that he is alright. We presume that the postal service is short staffed, like everyone else. Let us know. Thank you. Angela Pendleton


Hi staff at USPS in Cambridge! How would I schedule a fingerprinting appointment? Thank you! -Victoria Yellman


J'ai adressé un colis à mon fils le 11 décembre dernier. Il habite 40, Plymouth Street à CAMBRIDGE et n'a pas reçu le colis. Le n° du colis est EK226923144FR. Le CBP pour les douanes américaines m'a informé que le paquet n'avait pas été traité par eux. Ils estiment que le traçage, l'envoi et la livraison du colis est de la responsabilités d'USPS. Merci de m'informer du résultat des recherches que vous voudrez bien effectuer.


I just received a phone call from a mailwoman who contacted me about a package that had the wrong address. Her name is Dawn Lordan. She was fabulous & really went the extra mile. Thank you so much for having employees like her. Kathy Favro Fine Ingredients 730 Harding St Westfield NJ 07090 998-518-1650


Hello mrs and mr I appreciate information to send a 2kg shipimg order, from Cambridge post Office, to Republic of Cape Verde. Thanks for the info


Hi I live in North Cambridge in the Rindge Towers. For some reason, several tenants, including myself stop receiving our mail. We don't even get the junk mail anymore. Is mail not being delivered to our building?


I need your help locating package sent abroad. According to tracking history, the item is being held. Addressee has not been notified and we don`t know where to go to collect the item. Thanks for your response.


Good Morning, Tracking # 9114902307224564. Marg Chernosky called to hold package for son Luke. 1 Washington Court. I called several times and cant get through to anyone.
