Technically speaking, area codes are simply a part of your phone number that identifies where you’re calling from. With the prevalence of cell phones and numbers you can take with you anywhere, area codes don’t necessarily paint an accurate picture anymore unless you’re dealing with a landline. Nevertheless, your area code may hold a certain emotional significance. New Yorkers are famous for attaching particular associations to various area codes.

If you’re trying to track a caller in Arizona, there are only five possible area codes the call could come from, unlike neighboring California which boasts over two dozen. Many of these cover expansive areas, making it more difficult to track down your caller. While the 602 code covers just a small area surrounding Phoenix, 928 includes northern, western, and eastern Arizona, including part of the Grand Canyon and Navajo Nation. Just when you think you have found your caller, you’ll run into a problem like the diagonal split through Glendale, which leaves many next-door neighbors with different area codes.

As you check them, you’ll find that Arizona’s area codes can be both baffling and fascinating. Intermingling as they do, area codes in this state don’t carry as much prestige as those in other parts of the country. You may not find an Arizona area code on a list of the most popular digits in the country, but there’s still plenty to interest you in the fun facts behind these numbers.
