Most fans know that Fez was a nickname given to the character by his friends after he told them his real name, which was quite long, and they said they would never remember it. After that they started calling him Fez, which was formed from the words "Foreign Exchange Student." Much like how the show never revealed where the character was from, Fez's real name was also never revealed to the audience. It was teased multiple times throughout the show, but something always happened to keep viewers from hearing it. In one instance, a school bell rang while he said it. The most we learned during the show's run was that "the first five Ks are silent" in his last name.
However, the character does have a real name. In an interview with ABC celebrating the 10th anniversary of the comedy's series finale in 2016, Valderrama revealed that he had decided on Fez's real name himself, and that it was made up of the first name of each of the other characters on the show. "I said that is what Fez's real name is, because that is what he is," he said. "He is a little bit of all the characters on That '70s Show."
