Freemasons are members of a fraternal society that has been around for hundreds of years. Masons, as they are commonly called, meet in Masonic lodges to discuss business matters, plan events and socialize. Because many Masonic lodges are active in the community or sponsor charity events, there are many circumstances under which one might want to address a letter to a Masonic lodge. Freemasons respect formality and etiquette, so it's important to follow proper form in letters to them.

Prepare correspondence on quality stationery; business letters should be on letterhead. Write informal letters carefully in good penmanship. Thank-you notes, invitations and letters from children should be handwritten and do not need to be written like business letters.

Use proper titles when writing to an individual Mason. If you are unsure of the title, address the letter to "The Honorable (Name)." This can be abbreviated "Hon. (Name)." The leaders of Masonic lodges frequently take the title, "Most Worshipful."

Write the name of the lodge on the envelope. Lodge names are usually formatted "Lodge Name, Lodge Number." If the lodge is the head lodge for a state, address it to "Grand Lodge of Free and Accepted Masons of the State of (State Name)." Follow this style when formatting a business letter; business and informal letters alike should use the format in the greeting.
