BNL Mail Operations

The mailroom is responsible for affixing postage to official mail only and may inspect any mail represented as official business. Outgoing personal mail having postage affixed should be deposited in the U.S. Post Office.

All employees are requested to have personal mail addressed to them at their homes and not at the Laboratory. The Laboratory reserves the right to refuse to accept either advertising matter or personal mail addressed to employees at the Laboratory unless they reside on-site. The Laboratory address is the home address for on-site residents only. The U.S. Post Office in Building 179 has Post Office Boxes for rent to individuals and contractors desiring to receive mail at the Upton Post Office.

BNL Official Mail

Any International Mail must go through the Warehouse. A shipping memo request must be submitted and reviewed by Export Control. (This does not include personal mail)

All official Laboratory mail must show the name and office with the building # to all incoming and outgoing mail. Failure to do so may necessitate opening mail when some question arises on class of mail or when a reference number is required for the postage. The Senior Communications Clerk has authority to open and inspect any mail represented as official business to determine consistency with Laboratory procedure. The mail, which does not conform to Laboratory procedure, may be discarded if the receiver is not identified.

Official Laboratory U.S. mail will be forwarded by the least expensive appropriate class of mail unless designated otherwise by the sender. Postage of $15 or more on a single piece or $50 for volume mailing of multiple pieces.
