Can you put church flyers on a Mailbox?

Answer 1

In the United States...you can't put anything in or on a mailbox. Think of it like US. Government Property. They will come after you whether you are a church, or Boy Scouts. "no part of a mail receptacle may be used to deliver any matter not bearing postage, including items or matter placed upon, supported by, attached to, hung from, or inserted into a mail receptacle." http://pe.usps.gov/archive/html/dmmarchive0810/d041.htm

Answer 2

It is generally not allowed to place flyers on or inside mailboxes as they are considered federal property. It is recommended to check with local authorities or use other advertising methods to promote your church event.
