City population is shown in full. The share of each city inside 353 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.
What counties does area code 353 cover?

Caller ID is easily spoofed, so these figures reflect the number shown on caller ID, not the caller's true location – an area code alone never identifies a caller. The FTC does not verify the facts in these complaints. Source: FTC Do Not Call (DNC) Reported Calls Data, retrieved 2026-08-17.
Frequently Asked Questions about the 353 Area Code
Who called me from a 353 number?
A 353 number is assigned to Madison, Wisconsin, so a call may come from there. But caller ID is easy to fake, and scammers often spoof a local 353 code to look nearby, so a 353 number doesn't prove the caller is local. Recently, 8 unwanted-call complaints were reported to the FTC for numbers showing the 353 code (13% flagged as robocalls). If you don't recognize the number, let it go to voicemail; a real caller will leave a message.
Is 353 a scam area code?
No area code is a scam on its own. 353 is a normal, officially assigned code for Madison, Wisconsin. Spam callers spoof local codes to raise the odds you answer, so 353 on your caller ID says nothing about who is really calling. Recently, 8 unwanted-call complaints were reported to the FTC for numbers showing the 353 code (13% flagged as robocalls). Judge the call itself, not the area code.
Why do I keep getting calls from the 353 area code?
Repeated calls from different 353 numbers are usually spoofing: a robocaller rotates through 353 numbers so each call looks local and slips past simple blocks. Recently, 8 unwanted-call complaints were reported to the FTC for numbers showing the 353 code (13% 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 353 number?
If you aren't expecting a 353 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 353 area code?
Block a single 353 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 353 code also stops legitimate local calls, so use it only as a last resort.
