The President's Secret ZIP Code, Presidents have their own zip code, and a SECRET ONE for friends and family. Presidents get lots of mail and MANY DEATH THREATS in the mail too. "As the nation’s most visible and powerful leader, the President of the United States receives approximately 60,000-80,000 letters PER WEEK..  This is in addition to the 100,000 e-mails and thousands of phone calls received each day.  Every piece of correspondence sent to the President is processed and the White House Correspondence Office does its best to respond appropriately to all communication.  The Secret Service is often involved in the process as Presidents are frequently threatened and threats must be investigated in order to monitor credible dangers to the President or his family.  George W. Bush received approximately 4,000 threats against his life ANNUALLY; President OBAMA receives about FOUR TIMES as many threats. Because of the sheer amount of mail sent to the White House, it is difficult for the President to get personal mail.  A letter sent to the White House by a personal friend or family member of the President would go through all necessary screenings before possibly being passed on to staff who, at best, might pass the letter on to a Presidential secretary.  It is unlikely that the President would ever see a letter sent through those channels. However, President’s do have personal friends, they do have family members who want to send Christmas cards, they have bill collectors, and they have a need for mail from outside of the bubble of the White House.  As I previously wrote about in “The Blue Goose (and other Presidential Perks)”, the U.S. Postal Service establishes a SECRET PERSONAL ZIP code for the use of the President.  The President’s personal ZIP code is given to people who he would like to receive mail from during his time in the White House – sort of a VIP list for letters.  The President’s ZIP code is unique from any other location and given to people of the President’s choosing.  If the secret ZIP code is somehow leaked, the Postal Services issues a new one.  Each President has a new personal ZIP code created for him upon taking office.  Like every piece of mail or package that enters the White House, the letters to the President’s ZIP code are first examined for NUCLEAR, BIOLOGICAL or CHEMICAL contamination at a military facility near Washington, D.C.  Once they are screened, however, they are delivered directly to the President’s desk – a great feeling of (relatively) unfettered access for the mail sender and a breath of fresh air to Presidents wanting news or information unfiltered by the White House bubble." https://deadpresidents.tumblr.com/post/78147000455/the-presidents-secret-zip-code
