Just like an artist chooses a stage name, criminals have long used aliases to instill fear and avoid capture. These pseudonyms often embody part of the essence of the individual behind the mask, or are related in some way or another to their past.

Let's delve into the stories behind these 10 infamous criminal aliases and the individuals who wielded them.

Al Capone, dubbed "Scarface" for the distinctive scar on his face, was one of America's most notorious gangsters during the Prohibition era. He earned the scar during his time in the Five Points Gang of New York. Capone insulted a woman while working in a gang-operated dance hall, only to be viciously attacked by her brother, who slashed his face with a knife. In time, his hair-raising alias became synonymous with organized crime in Chicago, where he ran speakeasies and engaged in bootlegging.

Frank Abagnale, an American con artist famous for his many frauds against individuals and small businesses during the ‘60s, earned the alias "The Skyway Man" for his audacious scheme of impersonating a Pan Am pilot and using his status to cash fraudulent checks without suspicion everywhere in the world. His life was later portrayed in the acclaimed Steven Spielberg film "Catch Me If You Can."

John Dillinger was a notorious bank robber during the Great Depression, known for his brazen heists and daring escapes from the police. His dangerous exploits earned him the nickname "Jackrabbit" due to his graceful movements during heists, such as leaping over the counter - something he allegedly copied from the movies. The FBI also dubbed him "Public Enemy Number One," and his larger-than-life figure epitomized the glamorization of outlaws in American folklore.

The Zodiac Killer, an unidentified serial killer active in California during the late 1960s and early 1970s, earned his alias for his taunting letters sent to newspapers and police, filled with cryptic ciphers and threats and signed under the "Zodiac" pseudonym. Though the police identified a series of potential suspects, the killer behind the letters was never positively identified, leaving behind an enduring mystery surrounding his identity and motives.

Blackbeard was the nickname of Edward Teach, a notorious English pirate who roamed the Caribbean during the early 18th century. He earned his alias for his fearsome appearance and ruthless tactics. The pirate was described as a tall man with a thick black beard, often braided into pigtails. During battles, he often stuck lighted slow matches under his hat to scare his enemies. However, despite his appearance and reputation, most historians believe that Blackbeard never murdered or harmed those he held captive.

John Gotti, a powerful Mafia boss in New York City during the 80s, earned the alias "The Teflon Don" for his ability to evade conviction despite numerous charges against him. His apparent legal invincibility was achieved by intimidating witnesses and buying jury members with the help of the Gambino crime family. However, he was eventually convicted by the FBI after a lengthy investigation, receiving life in prison without parole.

Griselda Blanco, a Colombian drug lord known for her ruthlessness, earned the alias "The Black Widow" for reportedly ordering the killing of each of her husbands. Also known as the "Godmother", she rose to prominence in the underworld of Miami during the 1970s and was known for her penchant for eliminating rivals who dared cross her path.

Meyer Lansky was a key figure in organized crime during the Prohibition era, as he earned his alias "The Mob's Accountant" for his financial prowess in managing illicit enterprises. Lansky’s alias reflected his strategic role in introducing money laundering and offshore banking in 1932 to the American criminal underworld. However, until his death in 1983, he was never found guilty of anything more than illegal gambling.

Ted Kaczynski, an American domestic terrorist and mathematician, gained notoriety as "The Unabomber" for his targeting of universities and airlines with homemade bombs. But before his real identity was known, the FBI internally used the name UNABOM (meaning University and Airline Bomber) to refer to his case. The media soon picked up the FBI identifier and creatively transformed it into the "Unabomber."

Charles "Pretty Boy" Floyd, a Depression-era bank robber and folk hero, earned his alias for his youthful appearance and charm. His exploits and story contributed to the romanticized image of the outlaw as a Robin Hood figure, as he was believed to burn mortgage documents during robberies, in theory freeing many people from life-long debts.

Decoding

Being a "treasured guest" is not a compliment. This is the hidden meaning

Have you ever heard "Code Adam" while shopping for groceries at Walmart? Or maybe you’ve heard how "Dr. Firestone" was being paged during a routine hospital visit. They sound like harmless announcements. But behind these ordinary words are secret codes staff use to signal emergencies without causing panic. From hospitals and supermarkets to airports and Disney Parks, these phrases quietly warn employees that something is happening. You hope you never hear them, but if you do, it helps to know exactly what they mean.

We all love getting special attention at airports or hotel desks, but if you hear the clerk call you a "treasured guest," don’t feel so flattered. You may not be as VIP as one could think.

In the hospitality industry, "treasured guest" has become a humorous bit of industry folklore to describe someone causing trouble. Maybe a customer yelling at staff over expired coupons, demanding impossible accommodations, or throwing a full-blown tantrum at the front desk. Whatever it is, the phrase has become the staff’s secret way to warn co-workers without escalating the situation in front of the customers. Most guests don’t realize the meaning, but once you know it, you may start hearing it more often. We just hope it’s not about you.

Imagine you’re pushing a shopping cart through Walmart when suddenly the overhead speaker announces, "Code Adam." You can easily assume it’s some kind of employee meeting or cleanup request. But when you see them start locking the exits and moving around, you know something’s wrong.

This code was created in 1994 by Walmart in collaboration with the National Center for Missing & Exploited Children (NCMEC), in memory of the tragic case of 6-year-old Adam Walsh. Adam was abducted from a Sears department store in 1981 while shopping with his mother. His father, John Walsh, later became famous for hosting the TV program America’s Most Wanted and advocating for missing children. Even if Adam’s story ended in tragedy, Walmart created the emergency system in Adam’s memory, and other retailers soon adopted it nationwide, intending to have a quick response to missing or abducted children.

You’re sitting in a hospital waiting room during a routine check-up when you suddenly hear "Code Blue, Room 214." Most people immediately know it sounds serious, even if they are not entirely sure why.

The phrase "Code Blue" is used at hospitals to draw the necessary staff and equipment to perform a resuscitation. It was created in the early 1960s at Beathany Medical Center by Dr. Hughes Day. Before then, hospital resuscitations were often chaotic and poorly coordinated. In 1961, Dr. Day received a grant to build one of America’s first cardiac care centers, and he developed both the Code Blue alert system and the modern crash cart to improve survival rates during cardiac emergencies. Today, the system is used in hospitals across the country, sometimes with specialized versions like "Code Blue Pediatric" or "Code Blue Neonate."

Imagine visiting a loved one in the hospital when the intercom calmly announces, "Paging Dr. Firectone to the third floor." Your head surely goes, "Dr. Firestone’s probably having a busy day up there." He is, but it’s not what you think.

The phrase is actually a discreet fire alert used to warn staff about smoke, flames, or overheating equipment without frightening patients and visitors. Hospitals adopted these coded announcements after realizing that openly yelling "fire" over loudspeakers could create panic, especially among patients who aren’t able to move quickly. "Code Red" is an alternative used by many health centers today, but it also hints at the situation while keeping hallways calm.

You’re standing at a checkout counter when the cashier picks up the phone and quietly says, "I need a Code 10 authorization." If you think that’s just another way to get a supervisor’s approval or technical issue, think again. In reality, the cashier may suspect the credit card is stolen or fraudulent.

Code 10 was developed through a cooperative effort between major credit card companies like Visa and Mastercard, along with international standard organizations. As credit cards became more common in the 1960s and 1970s, stores needed a discreet way to alert banks about suspicious activity without directly accusing customers and potentially putting employees at danger. When a cashier requests a Code 10, the bank’s operator begins asking yes-or-no questions to assess the situation and guide the employee on what to do next.

You’ve probably experienced those long airport security lines. The wait is usually uneventful. But sometimes, you can hear "Code Bravo" over the speakers. Maybe it’s a delay, or maybe it’s an issue with luggage. Within seconds, people stop moving, the security line freezes, and exits may even close. It’s something bigger.

Code Bravo is the emergency phrase used by airport security and the Transportation Security Administration to signal a serious security threat, such as an unattended bag, a breach at a checkpoint, or someone slipping into a restricted area. The term comes from the international phonetic alphabet used in aviation and military communications, where "Bravo" represents the letter B. When this is called, security staff immediately lock down affected areas, stop screening lines, and search for the source of the threat. To passengers, it’s sudden and confusing, but to security, it’s a carefully rehearsed response.

You are heading back to your cabin on a cruise ship when the speakers announce, "Code Alpha, Deck 7." You may think Alpha is related to the captain, but that’s not the case. It means someone on board is suffering a medical emergency.

The phrase comes from the NATO phonetic alphabet, where "Alpha" represents the letter A. In maritime emergency jargon, it became shorthand for a Priority A medical situation requiring immediate response. Cruise lines such as Royal Caribbean and Disney Cruise Line commonly use the term, though some ships use variations like repeating "Alpha" three times. Once the code is announced, onboard medical teams rush toward the specified deck or cabin. If necessary, stretcher crews are mobilized, and in severe cases, the ship may even divert course toward the nearest port for emergency evacuation. Passengers are enjoying the views, but the staff is running to save a life.

Anyone who remembers the CB radio craze of the 1970s probably smiles when they hear "10-4." Movies, truckers, and radio fans turned those number codes into a part of American culture. So if you overhear "10-33" on a police scanner, you might assume it’s just another routine message. But it’s not as simple as it sounds.

The 10-code system was first created in 1937 by Illinois State Police communications director Charles Hopper and later standardized by the Association of Public Safety Communications Officials, better known as APCO. Officers needed short phrases they could understand clearly over crackling radio signals. The 10-33 code commonly means an officer needs emergency assistance. In some departments, it also signals radio silence so dispatchers can focus on the crisis unfolding in real time.

Disney World is amazing, the parks offer something for everyone, and there are things to see wherever you look. But that’s exactly the kind of place where a child can easily disappear into a sea of strollers, balloons, characters, and crowds. For that reason, Disney has developed the "Signal 70," which alerts cast members and security that a child has become separated from their family.

The number comes from older police and emergency radio systems, where "70" was commonly associated with missing persons. Disney adopted the phrase because it allows employees to communicate discreetly without frightening or alarming nearby guests. If a member finds the child, they gently -and magically- escort them to Baby Care Center, where they coordinate the reunion.

Cruises are great to relax, enjoying a good book under the sun with a nice drink by the side. Until you hear "Echo, echo, echo" on the speakers. If you do, something is happening somewhere else on the ship.

The code is used among cruise employees to signal that dangerous winds or a navigational hazard are affecting the ship. It comes from the international maritime phonetic alphabet, where "Echo" stands for the letter E. In maritime signalling, the letter traditionally means "I am altering my course to starboard." And, in time, the phrase became associated with urgent ship maneuvers and weather-related warnings. However urgent, the repetition of the word by three doesn’t represent life-threatening situations. It alerts the crew of a certain hazard to prepare while avoiding panic among passengers.
