City population is shown in full. The share of each city inside 203 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.

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 203 Area Code

Who called me from a 203 number?

A 203 number is assigned to Bridgeport, Connecticut, so a call may come from there. But caller ID is easy to fake, and scammers often spoof a local 203 code to look nearby, so a 203 number doesn't prove the caller is local. Recently, 1,199 unwanted-call complaints were reported to the FTC for numbers showing the 203 code (62% flagged as robocalls). If you don't recognize the number, let it go to voicemail; a real caller will leave a message.

Is 203 a scam area code?

No area code is a scam on its own. 203 is a normal, officially assigned code for Bridgeport, Connecticut. Spam callers spoof local codes to raise the odds you answer, so 203 on your caller ID says nothing about who is really calling. Recently, 1,199 unwanted-call complaints were reported to the FTC for numbers showing the 203 code (62% flagged as robocalls). Judge the call itself, not the area code.

Why do I keep getting calls from the 203 area code?

Repeated calls from different 203 numbers are usually spoofing: a robocaller rotates through 203 numbers so each call looks local and slips past simple blocks. Recently, 1,199 unwanted-call complaints were reported to the FTC for numbers showing the 203 code (62% 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 203 number?

If you aren't expecting a 203 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 203 area code?

Block a single 203 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 203 code also stops legitimate local calls, so use it only as a last resort.
