The number 480 can refer to different things depending on context:

• 480 is an area code in Arizona, USA. It serves the Phoenix metropolitan area and some surrounding communities in Maricopa and Pinal counties. It was created in 1999 as an overlay of area code 602 to relieve number exhaustion. Major cities with the 480 area code include Phoenix, Mesa, Chandler, Gilbert, Scottsdale, and Tempe.

• In Germany, Bundesstraße 480 (B 480) is a federal road in eastern North Rhine-Westphalia. It runs from Erndtebrück-Leimstruth through Winterberg and Brilon to Bad Wünnenberg and connects to the A 33 highway. This road dates back to 19th-century routes and was officially designated B 480 in the 1960s.

• The number 480 is also referenced in a bus route in Dortmund, Germany (line 480), connecting locations like Marten, Kirchlinde, Castrop, and Habinghorst, operating mainly on weekdays.

If you specify the context in which "480" is needed (phone area code, German road, bus line, or something else), a more focused explanation can be provided.
