Introduction
The 708 area code identifies calls across Chicago's south and west suburbs, and it has covered this stretch of Cook County since the metro's original numbering plan split in 1989.
Anyone doing business or living in these suburban communities has almost certainly dialed or received a call under this prefix.
This guide explains where the 708 area code reaches, how it narrowed to its current footprint after a later 1996 split, and how to tell a genuine local call from a spoofed one.
It also covers the practical details: which time zone governs the region and what it actually takes to set up a working business line under this prefix, whether you already live here or are simply setting up a new presence in the market.
Stick around, because the story behind these three digits explains how Chicago's suburbs keep issuing fresh phone numbers today.
- The 708 area code split away from Chicago's original 312 code in 1989, then narrowed further when 847 split off the northern suburbs in 1996.
- It now shares its territory with 464, an overlay added once demand for new numbers grew.
- Every community under this area code operates on Central time, same as the rest of the Chicago metro.
- Knowing what area code is 708 helps residents and business owners recognize genuine suburban Chicago calls.
The Suburbs That Answer to 708
The 708 area code covers Cook County's south and west suburbs, stretching from Oak Park and Cicero out through Chicago Heights and Orland Park. It sits alongside 773 and 312 inside the city proper, while 847 handles the suburbs to the north.
That layout makes the Chicago area one of the more layered numbering regions in the entire country.
Communities Sharing This Prefix
- Oak Park and Cicero, anchoring the inner-ring suburbs just west of the city
- Chicago Heights and Harvey, covering the south suburban corridor
- Orland Park and Tinley Park, serving the fast-growing southwest suburbs
- Berwyn and Forest Park, filling out the metro's western edge
Because the 708 area code stretches across so many distinct suburban communities instead of one compact town, it ends up serving a mix of industrial corridors, inner-ring bedroom communities, and fast-growing outer suburbs all under the same three digits. A caller from Oak Park and a caller from Orland Park share the exact same prefix despite living nearly 30 miles apart. That geographic spread is part of why understanding the boundaries of this area code matters more here than it might in a smaller, denser suburb.
From One Suburban Code to a Split, Then an Overlay
Area code 708 first appeared in 1989 when regulators split it away from Chicago's original 312 code, giving the entire suburban ring around the city its own numbering plan for the first time.
Rapid growth throughout the following decade meant even that dedicated suburban code needed more room within just a few years.
Planners eventually concluded that the 708 area code alone could no longer support both the northern and southern suburbs under one shared numbering plan.
Why 847 Took the Northern Suburbs
Regulators split 708 again in 1996, carving out area code 847 for the northern and northwestern suburbs while 708 kept the south and west. That geographic split meant residents in places like Evanston had to switch to new digits, while those in Cicero or Oak Park kept theirs. A later overlay, 464, was added on top of the remaining 708 territory once that split itself began running low on numbers, a smaller adjustment than the disruptive 1996 split had been.
What Time Zone Applies to a 708 Call
Every community inside the 708 area code operates on Central time, observing daylight saving right alongside downtown Chicago.
That shared time zone keeps scheduling simple for businesses, since a call placed at 9 a.m. in Cicero lands at 9 a.m. in Orland Park without any conversion.
Companies coordinating deliveries, appointments, or support calls across the south and west suburbs never have to double-check a client's local hour.

Red Flags Behind a Fake 708 Caller ID
The 708 area code itself is entirely legitimate, used daily by real suburban Chicago residents, hospitals, and small businesses across Cook County.
Scammers know that reputation, which is why they spoof 708 caller IDs to make fraudulent calls look local and trustworthy.
The digits on the screen never tell the full story; the behavior of the caller does, and that distinction matters just as much in a small suburb as it does downtown.
Common Patterns Behind Fraudulent Calls
- Urgent demands to pay a bill immediately or face disconnection
- Requests for gift cards, wire transfers, or cryptocurrency payment
- Callers claiming to be law enforcement or a utility company demanding personal details
- One-ring calls designed to trigger a costly callback
Habits That Keep You a Step Ahead
Treat any unexpected call under the 708 area code with the same caution you would use anywhere else in the state. According to the Federal Communications Commission, scammers routinely fake caller ID information to disguise their real location, so the area code alone never confirms who is calling. Hang up and dial the official number on a bill or website instead, especially whenever the request involves money or personal information, and let unfamiliar numbers go to voicemail until you can verify them. A legitimate business calling under this area code will never pressure a customer into paying instantly or sharing a one-time verification code over the phone.
“This is not a random three-digit prefix — it is Chicago's south and west suburbs' own calling identity, split away from 312 to keep local numbers flowing.”
Why Local Suburban Businesses Keep a 708 Phone Number
Businesses that serve Cicero, Oak Park, or the rest of the south and west suburbs gain something real by matching their number to the area code locals already recognize.
Callers answer faster, trust faster, and refer their neighbors faster once they see this area code on the screen instead of an unfamiliar toll-free line.
What area code is 708 signals to a customer here is simple: this business understands suburban Chicago and is easy to reach, whether the call comes from an inner-ring suburb or a fast-growing outer one.
Local Digits Versus a National Toll-Free Line
A toll-free number still makes sense for national brands chasing recognition everywhere at once. A 708 phone number instead tells a caller in Chicago Heights or Berwyn that the company on the other end is part of their own community, not a distant call center somewhere else. For local service businesses especially, that distinction often decides whether the phone gets answered at all, and it can quietly shape how quickly a first-time caller becomes a repeat customer. A cloud-based platform makes claiming that identity simple, even for a team that has never set foot in suburban Chicago.

The 708 area code is more than a random string of digits; it is the shared calling identity of Chicago's south and west suburbs.
It split away from 312 in 1989 and narrowed further in 1996 when 847 took over the northern suburbs, giving this stretch of Cook County its own dedicated numbering plan.
