708 area code — La Grange, IL geographic
Area code 708 is a geographic code serving La Grange, Illinois in the Central time zone. It has been in service since November 11, 1989. The same territory is also served by its overlay code (464/708 complex). Keep in mind the code identifies where the number was registered; the person calling may be elsewhere.
The code currently holds 783 working prefixes, held by 27 different carriers. Of these, 549 are pooled prefixes shared by multiple carriers. Numbers are anchored to 37 rate centers — billing localities that fix where each prefix belongs.
The code was carved out of 312 (1989). As demand grew it in turn gave rise to 847 (1996), 630 (1996), 464 (2022).
The current NANPA exhaust forecast for the 464/708 complex is 2Q 2053.
Local calls inside 708 are dialed 1+10D.
Practical takeaway: the 708 label narrows geography to Illinois, the prefix narrows it to a locality, and neither authenticates a caller. Verification means calling back through a number you found yourself.

FAQ
Is 708 a toll-free number?
No. 708 is a geographic code; calls are billed like any other domestic call. Toll-free codes are 800, 833, 844, 855, 866, 877 and 888.
Why do 464 and 708 cover the same place?
They are overlays: when a code runs low on numbers, a new code is added over the same territory instead of splitting it. The 464/708 complex shares one service area, and local calls are dialed with 10 digits.
Will 708 run out of numbers?
NANPA's current forecast projects exhaust in 2Q 2053 — decades of capacity remain.
Why am I getting spam calls from 708 numbers?
Scammers spoof recognizable area codes so calls look local or familiar. A displayed 708 number does not prove the call originated there — see our guide to spotting spoofed calls.
Where is a 708 number from?
708 is assigned to La Grange and surrounding areas of Illinois in the Central time zone. The three digits after the area code (the prefix) narrow it down to a rate center.
