Why Do Fake Phone Numbers Start With 555?

As soon as an actor in a movie or TV show starts rattling off a phone number, every viewer knows what the first three digits will be: 5-5-5. How did “555” become the convention for fake phone numbers, and are there any real 555 numbers? Let’s dial up some answers.

Why do TV and movies need the fake 555 numbers? Just ask anyone who had the misfortune of having the number 867-5309 how their life changed after Tommy Tutone's 15 minutes of fame. Apparently some tiny fraction of the population—we’re guessing a fraction that largely consists of adolescent boys—thinks it’s hilarious to call any number they see on the screen. To curb these nuisance calls, movies and shows have been using the fake 555 numbers since as far back as the 1950s. (In keeping with the old exchange-naming convention, back then it was “KLondike 5” or “KLamath 5.”)

It’s hard to pin down exactly how 555 became the go-to fake prefix for phone numbers. In the book Easy as Pi: The Countless Ways We Use Numbers Every Day, author Jamie Buchan speculates that the repeated digit may have made the combination memorable, which helped it gain traction. Buchan adds that since no major place names in the United States began with a combination of the letters J, K, and L (the letters assigned to the 5 key on a phone), the KLondike/KLamath prefix wasn’t exactly a coveted commodity.

Since the early 1970s there’s been at least one 555 number callers can dial and get an answer—555-1212 is a standard number that rings directory assistance. The rest of the 555 numbers have largely gained fame as fake numbers in movies and on TV. (The number 555-2368 has risen to particularly rarefied air, possibly because of the “2368” combo’s use in old phone ads. Dialing 555-2368 will get you the Ghostbusters, the hotel room from Memento, Jim Rockford of The Rockford Files, and Jaime Sommers from The Bionic Woman, among others.)

Real Fake Numbers

What you may not know, though, is that there are many more “real” 555 phone numbers. Since 1994, 555 numbers have actually been available for personal or business use. That’s when the North American Numbering Plan Administration started taking applications from people and businesses who wanted their own 555 numbers. Theoretically, these numbers would have worked from anywhere in the continent; dialers would be able to dial 555-XXXX and always end up with the same number regardless of area code. The hope was that if you needed, say, a taxi anywhere in the country, you could just remember one number that would always work.

Things didn’t work out quite so smoothly. People and businesses snapped up the 555 numbers —except for 555-0100 through 555-0199, which were held back for fictional use—but they soon learned that owning a phone number isn’t all that useful if you don’t also own a phone company that can connect the number. Phone companies protested that setting up these services would be wildly expensive; in 2003 Verizon told The New York Times that adding the nationwide 555 service to its systems would cost the company $108 million. (Verizon did offer to hook up the 555 numbers for owners, but the same Times story noted that the service usually required a $2,500 set-up fee per area code.)

Skeptics claimed that the phone companies were just dragging their feet so the 555 numbers didn’t sap cash away from 800 numbers. There may be some truth to that theory, but the 555 system still isn’t up and running in any meaningful way. The list of people and entities that own the numbers is a pretty amusing read, though. It’s mostly newspapers, hospitals, random people, and the state of Nevada.

What's the Difference Between Memorial Day and Veterans Day?

It may not be easy for some people to admit, but certain national holidays often get a little muddled—namely, Memorial Day and Veterans Day. In fact, the U.S. Department of Veterans Affairs sees the confusion often enough that they spelled out the distinction on their website. The two days are held six months apart: Veterans Day is celebrated every November 11, and Memorial Day takes place on the last Monday of May as part of a three-day weekend with parades and plenty of retail sales promotions. You probably realize both are intended to acknowledge the contributions of those who have served in the United States military, but you may not recall the important distinction between the two. So what's the difference?

Veterans Day was originally known as Armistice Day. It was first observed on November 11, 1919, the one-year anniversary of the end of World War I. Congress passed a resolution making it an annual observance in 1926. It became a national holiday in 1938. In 1954, President Dwight D. Eisenhower changed the name from Armistice Day to Veterans Day to recognize veterans of the two world wars. The intention is to celebrate all military veterans, living or dead, who have served the country, with an emphasis on thanking those in our lives who have spent time in uniform.

We also celebrate military veterans on Memorial Day, but the mood is more somber. The occasion is reserved for those who died while serving their country. The day was first observed in the wake of the Civil War, where local communities organized tributes around the gravesites of fallen soldiers. The observation was originally called Decoration Day because the graves were adorned with flowers. It was held May 30 because that date wasn't the anniversary for any battle in particular and all soldiers could be honored. (The date was recognized by northern states, with southern states choosing different days.) After World War I, the day shifted from remembering the fallen in the Civil War to those who had perished in all of America's conflicts. It gradually became known as Memorial Day and was declared a federal holiday and moved to the last Monday in May to organize a three-day weekend beginning in 1971.

The easiest way to think of the two holidays is to consider Veterans Day a time to shake the hand of a veteran who stood up for our freedoms. Memorial Day is a time to remember and honor those who are no longer around to receive your gratitude personally.

What Is the Kitchen Like on the International Space Station?

Clayton C. Anderson:

The International Space Station (ISS) does not really have a "kitchen" as many of us here on Earth might relate to. But, there is an area called the "galley" which serves the purpose of allowing for food preparation and consumption. I believe the term "galley" comes from the military, and it was used specifically in the space shuttle program. I guess it carried over to the ISS.

The Russian segment had the ONLY galley when I flew in 2007. There was a table for three, and the galley consisted of a water system—allowing us to hydrate our food packages (as needed) with warm (tepid) or hot (extremely) water—and a food warmer. The food warmer designed by the Russians was strictly used for their cans of food (about the size of a can of cat food in America). The U.S. developed a second food warmer (shaped like a briefcase) that we could use to heat the more "flexibly packaged" foodstuffs (packets) sent from America.

Later in the ISS lifetime, a second galley area was provided in the U.S. segment. It is positioned in Node 1 (Unity) and a table is also available there for the astronauts' dining pleasures. Apparently, it was added because of the increasing crew size experienced these days (6), to have more options. During my brief visit to ISS in 2010 (12 days or so) as a Discovery crewmember, I found the mealtimes to be much more segregated than when I spent five months on board. The Russians ate in the Russian segment. The shuttle astronauts ate in the shuttle. The U.S. ISS astronauts ate in Node 1, but often at totally different times. While we did have a combined dinner in Node 1 during STS-131 (with the Expedition 23 crew), this is one of the perceived negatives of the "multiple-galley" scenario. My long duration stint on ISS was highlighted by the fact that Fyodor Yurchikhin, Oleg Kotov, and I had every single meal together. The fellowship we—or at least I—experienced during those meals is something I will never, ever forget. We laughed, we argued, we celebrated, we mourned …, all around our zero-gravity "dinner table." Awesome stuff!
