Frequently asked questions

What is the process for obtaining a virtual phone number in Illinois, and does it allow me to choose area codes specific to cities like Chicago or Springfield?

Obtaining a virtual phone number in Illinois is straightforward with FlyNumber. You can choose from various area codes specific to cities within the state, such as 312 for Chicago or 217 for Springfield. This feature allows you to maintain a local presence, which can be beneficial for business and personal communications, reflecting a local identity that resonates with Illinoisans' strong sense of community and local pride.

Can I use my Illinois virtual phone number to send and receive SMS, and will it work for services that require 2FA verification?

Yes — all US FlyNumbers, including those from Illinois, can receive SMS, and incoming messages are forwarded to the email on file for a small per-segment fee. 2FA / short-code verification texts aren't guaranteed due to compatibility issues, which is worth keeping in mind especially in tech-savvy areas like the Chicago metro. 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).

How quickly can I activate a new virtual phone number in Illinois, and are there any specific requirements?

Activating a new virtual phone number in Illinois is nearly instantaneous. There are no special requirements to get started, making it easy for anyone, whether you’re setting up a new business in the bustling streets of Chicago or managing personal matters from the quieter parts of central Illinois.

I'm interested in setting up a voicemail system for my Illinois number. What options does FlyNumber offer?

FlyNumber provides a versatile cloud phone system where you can set up voicemail, call menus, and more. This system is particularly beneficial for Illinois users, allowing them to manage communication effectively, whether it’s for coordinating community events in Urbana-Champaign or handling customer inquiries in Peoria.

If I have a business with multiple locations across Illinois, can I manage several numbers through one account?

Absolutely, FlyNumber allows you to purchase and manage multiple phone numbers through a single account. This is perfect for businesses operating in multiple Illinois locations, from the historic sites of Springfield to the innovative hubs of Chicago, ensuring you can keep all your communications streamlined across different areas.

How does the call forwarding feature work with Illinois virtual numbers, and what are the costs?

FlyNumber allows you to forward your Illinois virtual number to any other number worldwide at a low per-minute rate. This feature is invaluable for Illinois residents and businesses who want to stay connected whether they’re dealing with clients from across the Mississippi River or partners in overseas markets.

Can I use FlyNumber to route calls based on the time of day or caller ID in Illinois?

Yes, our cloud phone system enables you to route calls based on the time of day or caller ID, which can be particularly useful for businesses in Illinois that cater to a diverse clientele across different time zones. This flexibility ensures that you’re providing timely responses, essential for maintaining good customer relations in fast-paced cities like Chicago or for ensuring peace of mind during off-hours in quieter, rural areas.

Some background on Illinois and its area codes

Illinois is served by multiple area codes, with 312 being one of the most notable, covering downtown Chicago. Introduced in 1947, 312 was among the original area codes established by AT&T's North American Numbering Plan. As Chicago and its suburbs expanded, additional area codes were introduced to accommodate the growing demand.

By the late 20th century, the Chicago metropolitan area required more area codes, leading to the introduction of 773 in 1996 for the city's outer regions. Other prominent area codes include 847 for the northern suburbs, 630 for the western suburbs, and 708 for the southern suburbs. These changes reflect population growth and increased telecommunications needs.

Illinois' area code system has continued to evolve with overlay plans, such as 872, introduced in 2009, overlaying 312 and 773. This allows for more phone numbers without geographic restrictions. The state's numbering plan adapts to modern telecommunications demands while maintaining historical significance in America's telephonic landscape.
