How precisely can a proxy target Illinois?
Illinois has 12.7 million residents (2025 Census estimate); one FiftyStateProxy username reaches all of Illinois, only Chicago, or a single Illinois ZIP code. The four levels:
- All of Illinois:
state-il. - Chicago:
state-il-city-chicago. - One ZIP:
zip-plus an Illinois ZIP from 600–620, 622–629. - One network:
asn-plus an Illinois AS number such as AS6079 RCN (Astound).
How to set up a US proxy shows where the Illinois username goes in each tool; what ZIP code proxy targeting does covers ZIP-level Illinois sessions.
Which Illinois city ids does the gateway accept?
| Illinois city | Username parameter |
|---|---|
| Chicago | city-chicago |
| Aurora | city-aurora |
| Naperville | city-naperville |
| Joliet, Rockford and smaller towns | zip- + a local ZIP |
Availability per Illinois city varies with how many homes are online.
Which home ISPs and ASNs sit behind Illinois residential IPs?
The home networks most often behind Illinois IPs are AS7922 Comcast (Xfinity) and AS7018 AT&T, per public routing registries. BroadbandNow lists Xfinity (Comcast), AT&T Fiber, Astound Broadband (RCN) among Illinois home-internet providers; each Illinois exit IP carries the ASN of its ISP:
- AS7922 Comcast (Xfinity)
- AS7018 AT&T
- AS6079 RCN (Astound)
- AS21928 T-Mobile USA
- AS5650 Frontier
- AS30036 Mediacom
These are registry facts about Illinois networks, not FiftyStateProxy IP counts. -asn- keeps a long Illinois crawl on Astound Broadband (RCN) alone. Mobile networks in Illinois: T-Mobile, AT&T, Verizon; FiftyStateProxy 4G/5G carrier ports are sold US-wide, not per state.
What do teams check from an Illinois IP address?
Teams rent Illinois IPs to load public pages as Illinois households see them:
- Local SEO rank tracking across Chicago neighborhoods and collar-county suburbs
- Monitoring public grain-bid and farm-input price pages across central Illinois
- Ad verification for campaigns bought in the Chicago DMA (Nielsen #3)
An ad audit in an Illinois DMA such as Chicago needs a city id or ZIP inside that market. An Illinois landing page that shows none of the area codes 312, 773, 847, 630, 708, 815, 217, 618 is serving the wrong local number. Chicago rank tracking follows how to track local rankings by ZIP code; Illinois price checks follow which proxies suit price monitoring.
Illinois keeps Central time, so one schedule covers every Illinois city id and ZIP.
What does Illinois proxy traffic cost?
A 1 GB plan for Chicago or any Illinois ZIP costs $1.50, ASN targeting included. At $0.52/GB, 1 TB costs 65% less per GB than the 1 GB plan (October 2026). See how much US residential proxies cost.

Which other East North Central states can I target?

What else do buyers ask about Illinois proxies?
Is Chicago included when I buy Illinois residential proxies?
Yes. Every plan covers all of Illinois, and city-chicago limits a session to Chicago at no extra cost. Aurora and Naperville have city ids on the same plan.
Can I target any ZIP code in Illinois?
Yes: any five-digit ZIP starting with 600–620, 622–629. A sparsely populated Illinois ZIP returns fewer IPs than a dense one in Chicago, so keep city-chicago as a fallback.
Which Illinois ISP should I pick for ASN targeting?
The one your audience uses. Besides Xfinity (Comcast), Illinois homes connect through Astound Broadband (RCN) and T-Mobile Home Internet; their AS numbers are listed above. Test the chosen Illinois network on the 1 GB plan ($1.50) first.
Which TV markets can I audit with Illinois IPs?
The DMAs covering Illinois include Chicago · Champaign–Urbana–Springfield–Decatur · Peoria–Bloomington · Rockford. Use a ZIP inside each Illinois market you compare.
Is a residential proxy legal to use in Illinois?
Generally yes, as long as each Illinois job respects the target site's rules, US computer-crime and anti-spam law, and our acceptable use policy. This is general information, not legal advice.
