You Can Have My PIN Number #funfacts #finance #cybersecurity #data #lifehacks PIN numbers are four-digit codes most of us use without much thought, but they reveal fascinating patterns in human behavior. With only 10,000 possible combinations, you'd think PINs would be equally distributed—but they're not. The most common PIN, by far, is 1234. In fact, it’s so popular that nearly 11% of people use it. Other frequent choices include simple patterns like 1111 or 0000, which are easy to remember but also easy for a thief to guess. Birthdays are another go-to option. Dates like 1984 or 0704 (July 4th) appear frequently because they’re meaningful to us. What’s surprising is how even the keypad layout influences choices. For example, 2580, which runs straight down the middle of a phone keypad, is disproportionately common—possibly because it feels intuitive or visually satisfying. At the other end of the spectrum, the least popular PINs are random-looking combinations like 8068 or 8093. They’re rarely chosen because they lack memorable patterns or personal significance.
