City population is shown in full. The share of each city inside 309 is measured from Census tract centroids, not estimated from a rate-center match – so a city split between two codes appears on both, at the fraction each one actually holds. The “% of listed-city population” column uses the full populations of the cities listed here.

Frequently Asked Questions about the 309 Area Code
Who called me from a 309 number?
A 309 number is assigned to Peoria, Illinois, so a call may come from there. But caller ID is easy to fake, and scammers often spoof a local 309 code to look nearby, so a 309 number doesn't prove the caller is local. Recently, 2,383 unwanted-call complaints were reported to the FTC for numbers showing the 309 code (81% flagged as robocalls). If you don't recognize the number, let it go to voicemail; a real caller will leave a message.
Is 309 a scam area code?
No area code is a scam on its own. 309 is a normal, officially assigned code for Peoria, Illinois. Spam callers spoof local codes to raise the odds you answer, so 309 on your caller ID says nothing about who is really calling. Recently, 2,383 unwanted-call complaints were reported to the FTC for numbers showing the 309 code (81% flagged as robocalls). Judge the call itself, not the area code.
Why do I keep getting calls from the 309 area code?
Repeated calls from different 309 numbers are usually spoofing: a robocaller rotates through 309 numbers so each call looks local and slips past simple blocks. Recently, 2,383 unwanted-call complaints were reported to the FTC for numbers showing the 309 code (81% flagged as robocalls). Blocking one number rarely helps; voicemail screening, your carrier spam filter, and the Do Not Call Registry work better.
Should I answer an unknown 309 number?
If you aren't expecting a 309 call, let it ring to voicemail. Legitimate callers leave a message, most robocallers hang up when no one picks up, and answering can mark your number as active and bring more calls.
How do I block calls from the 309 area code?
Block a single 309 number from your recent-calls list (iPhone: tap the number, then Block this Caller; Android: tap the number, then Block or report spam). To cut the volume, turn on Silence Unknown Callers on iPhone or spam protection on Android, enable spam filtering from your carrier, and register at DoNotCall.gov. Blocking the entire 309 code also stops legitimate local calls, so use it only as a last resort.
