Mail Services & Deliveries

Standard mail delivery is handled daily through the central U.S. Postal Service (opens in new window) mailroom located on the ground floor of One Main Street and 101 Main Street.  A United States Postal employee sorts the mail into each tenant’s locked mailbox.  Keys to these mailboxes will be distributed by the Property Management Office.

Packages for pick-up may not be left at the front desk of the building.  The building will not be responsible for any package left unattended.  Security cannot, under any circumstances, sign for packages or deliveries. 

Guidelines in Regards to U.S. Mail

Please note that the Property Management Office does not have access to the U.S. Postal Service mailroom areas. 

The following guidelines apply:

  1. Excess Tenant mail that will not fit into the Tenant’s mail slot will be separated into a U.S. mail container for pick-up.  We encourage Tenants not leave mail in these containers overnight.  The building is not responsible for lost or undelivered mail.
  2. Mail delivery and pick-up is made daily from the mailroom between 4:00 P.M. and
    5:00 P.M. There is no U.S. postal service on weekends or federal holidays.
  3. United Parcel Service and FedEx drop boxes are located near the mail area of each building.  Please contact the Property Management Office for exact locations.
  4. If you wish to pick up your mail at the post office, arrangements can be made at the Cambridge Post Office in Central Square.  Their telephone number is 617-876-0620.  Please note that mail addressed to a specific person will be undeliverable without a company name present.
