When you’re dealing with calls in and around the Denver International Airport and the wider metro area, you’re primarily going to encounter three main Denver area codes : 303 , 720 , and the newer 984 . Yes, guys, there isn’t one single, exclusive area code just for DIA itself. Instead, the airport, being a part of the Denver metropolitan statistical area, falls under the umbrella of these regional codes. Think of it like this: just as a specific neighborhood shares an area code with the broader city, DIA shares its codes with Denver. Historically, 303 was the original and sole area code for the Denver metropolitan area and much of northern Colorado. It’s the classic, the OG, if you will. As Denver grew and more phone numbers were needed (hello, everyone getting a cell phone!), the 720 area code was introduced as an overlay . What does an overlay mean? It means that new numbers in the same geographic region started getting assigned the 720 prefix, rather than 303. This is why you’ll find businesses and individuals with both 303 and 720 numbers right next door to each other. You don’t get to choose; it’s simply what’s available when a new line is activated. More recently, the 984 area code was approved as another overlay for the Denver metro area, further expanding the available numbers. This is a common practice in densely populated regions to prevent numbers from running out. So, when you’re making a call, whether you’re trying to reach an airline, a car rental agency at DIA, a hotel downtown, or even a local friend, you’ll need to dial the full 10-digit number (area code + 7-digit number), even if it’s a “local” call within Denver. This 10-digit dialing requirement is a direct result of the overlay system. Before overlays, you could often dial just the 7-digit number if it was within the same area code. Not anymore, folks! Always dial the full ten digits to ensure your call goes through without a hitch. This is crucial for anyone using their phone in the region, especially if you’re calling a specific service or contact related to your Denver International Airport travel plans. So, remember: 303 , 720 , and 984 are your key players here. Don’t be surprised to see numbers with any of these prefixes. Whether you’re hailing a ride, calling a restaurant, or contacting airport services, you’re likely to encounter numbers beginning with one of these essential Denver area codes . Keep this in mind, and your communication will be smooth sailing during your Mile High City adventure! Being informed about these nuances not only makes dialing easier but also helps avoid those frustrating
