In airline reservation systems, a record locator is an alphanumeric or alpha code used to access a specific record. They are typically 6 characters in length though Easyjet currently uses record locators which are either 6 or 7 characters.. When a passenger, travel agent or airline employee refers to a record locator they typically mean a pointer to a specific reservation which is known as a Passenger Name Record or PNR. However, a record locator can point at records containing other forms of data. Record locators are unique within a given system at a specific point in time. Because the number of character combinations in 6 characters is finite albeit very large, record locators get reused once the data to which it refers has been purged from the system. Because 1, I and L can be confused
