Frequently asked questions

Can I use a FlyNumber to support my tourism business in Colorado?
Absolutely! A FlyNumber can be an excellent tool for your tourism business, allowing you to have a local presence in Colorado. Whether you’re based in the bustling city of Denver or near the scenic Rocky Mountains, you can use a FlyNumber to make it easier for local clients to reach you. Plus, setting up a call menu can help direct your callers to the right department, enhancing customer service.
How quickly can I get a virtual phone number set up if I'm starting a new business in Boulder?
Activating a new US FlyNumber is nearly instantaneous. Once you choose your number, it can be up and running almost immediately. This is perfect for new businesses in Boulder who want to establish a local presence quickly and start connecting with the vibrant community there.
I run a ski resort in Aspen, how can FlyNumber help me handle high call volumes during the season?
FlyNumber's cloud phone system can be a game-changer for handling the high volume of calls during the ski season in Aspen. You can set up call menus that efficiently direct your guests to reservations, customer service, or emergency contacts. Additionally, the time-based routing feature can manage calls effectively during peak and off-peak hours, ensuring that you never miss a call from a guest.
Will a FlyNumber allow me to maintain my Denver business contacts while I travel out of state?
Yes, with FlyNumber, you can forward your local Denver phone number to any voip solution or regular phone number worldwide. This means you can continue to manage your business calls without interruption, regardless of your location, maintaining your connection with the Denver community and ensuring business continuity.
Can I receive text messages on my FlyNumber if I'm based in Colorado Springs?
All US FlyNumbers, including those for Colorado Springs, can receive SMS — incoming texts are forwarded to the email on file for a small per-segment fee. 2FA / short-code verification texts aren't guaranteed. You can also send personal, person-to-person texts to numbers outside the US — though delivery depends on the receiving carrier accepting texts from US numbers. Texting US numbers is coming soon and will run as A2P, the registered route US carriers require (that's also the path business texting will use).
I manage a gallery in the Art District on Santa Fe, Denver; how can I use a FlyNumber to enhance visitor experience?
A FlyNumber can enhance your gallery visitor's experience by providing them with a direct local contact number where they can inquire about exhibit timings, featured artists, or event bookings. You can also set up a voicemail system through the cloud phone system, ensuring that you capture all inquiries even during times when the gallery is closed or if you're unavailable to answer the phone.
Is it possible to use a FlyNumber for a healthcare clinic in Fort Collins?
Yes, a FlyNumber is ideal for healthcare clinics in Fort Collins or anywhere in Colorado. You can establish a local presence, making it easier for patients to reach out. Additionally, the call menu and voicemail features can help manage appointments and provide information on clinic services, which is crucial for maintaining patient relations and ensuring efficient communication.

Some background on Colorado and its area codes

Colorado's telecommunications landscape began with the introduction of area code 303 in 1947, covering the entire state. As population and demand increased, area code 719 was added in 1988 to serve the southeastern and central regions, including cities like Colorado Springs and Pueblo, thus alleviating the 303 area code's growing burden.

In 1995, area code 970 was created to serve the western and northern portions of Colorado, separating from the 303 area code. This change primarily affected cities such as Fort Collins, Grand Junction, and Aspen. The original 303 area code was further supplemented with area code 720 in 1998, employing an overlay strategy for the Denver metropolitan area.

Further growth led to the introduction of area code 983 in 2022 as an additional overlay to the 303 and 720 area codes, ensuring adequate number availability in the Denver region. This modern approach reflects Colorado's sustained population growth and technological advancement, maintaining communication efficiency across its expanding urban and rural areas.
