In this formulation, language variation can be divided into two categories: dialect, for variation according to user, and diatype for variation according to use (e.g. the specialised language of an academic journal). This definition of diatype is very similar to those of register.
North American area code 602 is a state of Arizona telephone area code that covers most of the city of Phoenix.It was one of the original area codes established in October 1947 and had originally covered the entire state of Arizona until 1995, when area code 520 was created as the state's second area code.he area code divider between 602 and 623 was drawn in such a way that in some neighborhoods, homes only a few hundred feet away from each other may have different area codes.
The 602 area code covers the majority of Phoenix residents. Originally established back in 1947, the 602 area code initially covered the entire state of Arizona. Due to massive increases in population, a split was necessary and other area codes were created in 1995 and 1999 to cover the rest of Arizona.Happily, most of Phoenix was able to retain the coveted 602 area code.he 602 area code is divided up into different urban villages. Some of these villages are traditionally important to the area, while others are relatively new and still developing.
