Government Look-Alike Mail That brown envelope in your mailbox looked so official you thought it was from a government agency. Even the name, return address, and seal looked official. Such mailings can be deceptive and confusing, and are sometimes illegal. They typically contain sweepstakes solicitations or requests for donations to political causes. Such mailings are no longer allowed unless: The entity actually has a government connection, approval, or endorsement. The mail and its envelope bear a notice that disclaims such connection, approval, or endorsement by a government agency. The material is contained in a publication purchased or requested by the addressee. Carefully read the material inside the envelope to determine if it really is from a government agency.
