City population is shown in full. The share of each city inside 603 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 603 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 603 Area Code
Who called me from a 603 number?
A 603 number is assigned to Manchester, New Hampshire, so a call may come from there. But caller ID is easy to fake, and scammers often spoof a local 603 code to look nearby, so a 603 number doesn't prove the caller is local. Recently, 878 unwanted-call complaints were reported to the FTC for numbers showing the 603 code (57% flagged as robocalls). If you don't recognize the number, let it go to voicemail; a real caller will leave a message.
Is 603 a scam area code?
No area code is a scam on its own. 603 is a normal, officially assigned code for Manchester, New Hampshire. Spam callers spoof local codes to raise the odds you answer, so 603 on your caller ID says nothing about who is really calling. Recently, 878 unwanted-call complaints were reported to the FTC for numbers showing the 603 code (57% flagged as robocalls). Judge the call itself, not the area code.
Why do I keep getting calls from the 603 area code?
Repeated calls from different 603 numbers are usually spoofing: a robocaller rotates through 603 numbers so each call looks local and slips past simple blocks. Recently, 878 unwanted-call complaints were reported to the FTC for numbers showing the 603 code (57% 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 603 number?
If you aren't expecting a 603 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 603 area code?
Block a single 603 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 603 code also stops legitimate local calls, so use it only as a last resort.
Where is area code 603?
Area code 603 covers Manchester and the surrounding area in New Hampshire, spanning 97 cities with about 1,377,529 residents. No other code overlays this region, so 603 alone identifies the area.
When did area code 603 go into service?
Area code 603 went into service on January 1, 1947.
Is 603 a real area code?
Yes. 603 is an active code in the North American Numbering Plan, assigned by NANPA and in service for Manchester, New Hampshire. A real code can still show up on spoofed spam calls, so treat unknown 603 calls with normal caution.
What timezone is the 603 area code in?
The 603 area code is in the Eastern Time (ET). Because a number can be kept when someone moves or switches to VoIP, a specific 603 caller may not be in that zone.
How do I call a 603 number from abroad?
From outside the US, dial your country's exit code, then 1 (the US country code), then 603 and the seven-digit number. From a mobile phone you can usually just enter +1 603 followed by the number and let the phone add the exit code for you.
