Connecticut Area Codes – 203, 475, 860, 959: What They Mean & How to Trace Any Connecticut Phone Number
Every Connecticut phone number begins with a three-digit Connecticut area code — the part of the number that indicates where the call was originally registered. These 203, 475, 860, and 959 area codes aren’t just random digits; they’re your first clue in identifying the caller’s possible location.
Whether you get a call from Bridgeport in the 203 area code, New Haven in the 475 area code, Hartford in the 860 area code, or Manchester in the 959 area code, knowing the Connecticut area code helps you start your search with confidence.
Connecticut’s Four Active Area Codes
- 203 Area Code – Covers Bridgeport, New Haven, Stamford, Norwalk, Danbury, and other southwestern Connecticut communities. A 203 reverse lookup or 203 phone number lookup can confirm if a call is genuinely from this region using our Bridgeport or New Haven phone number lookup tool.
- 475 Area Code – An overlay for the 203 area code region, serving the same southwestern Connecticut cities such as Bridgeport, Stamford, and Norwalk. A 475 reverse lookup or 475 phone number lookup helps verify if a number is truly local or a spoofed call.
- 860 Area Code – Assigned to Hartford, New Britain, Bristol, Torrington, and many cities in northern, eastern, and central Connecticut. Running an 860 reverse lookup or 860 phone number lookup can match a call to its likely origin.
- 959 Area Code – An overlay for the 860 area code region, covering much of northern and eastern Connecticut including Hartford, Manchester, and New London. A 959 reverse lookup or 959 phone number lookup confirms whether the call is genuine or spoofed.
Why Prefix Numbers Matter
While Connecticut area codes narrow down the region, they don’t always pinpoint the exact location. The prefix numbers — the three digits after the area code — can identify the specific city, town, or local exchange where the phone number was first assigned.
At CTPhoneLookup.com, you can combine Connecticut area codes with Connecticut prefix numbers to trace any Connecticut phone number. Our Connecticut reverse phone lookup tool can reveal the caller’s name, business, address history, linked social media profiles, phone type (mobile, landline, or VoIP), carrier details, and matches from the Connecticut phone directory.
Protecting Against Spoofed Calls
Scammers often spoof numbers to appear local — a 203 area code might look like it’s from Bridgeport, or an 860 area code might seem like it’s from Hartford, when it’s not. Our tools verify whether the number’s location is genuine or fake, helping you avoid scams.
You Can Use CTPhoneLookup.com For:
- Checking a suspicious number with a 203 phone number lookup or 860 phone number lookup.
- Searching the Connecticut phone directory for a name or address.
- Looking up Connecticut prefix numbers for a specific area.
- Using a Bridgeport phone number lookup, Hartford phone number lookup, New Haven phone number lookup, or Stamford phone number lookup to confirm a caller.
With complete coverage of all Connecticut area codes — 203, 475, 860, and 959 — plus every prefix in the state, CTPhoneLookup.com gives you fast, accurate, and private results so you always know exactly who’s trying to reach you.

Connecticut’s Largest Cities – Populations, Area Codes & Common Prefix Numbers
When you’re trying to figure out where a Connecticut phone number originated, the first step is to look at its area code and the next three digits, known as the prefix number. These two parts of the number can reveal a lot about the caller’s possible location — often before you even run a Connecticut reverse phone lookup. By combining area code and prefix data with population information, you can quickly narrow down whether the number is tied to a major metro area like Bridgeport, New Haven, Stamford, Hartford, Waterbury, or Norwalk, or if it’s coming from a smaller city or rural community in Connecticut.
For example, calls from the 203 area code typically originate from Bridgeport, New Haven, Stamford, Norwalk, and Danbury. The 475 area code is an overlay for the 203 region, covering the same southwestern Connecticut cities. The 860 area code covers Hartford, New Britain, Bristol, Torrington, and many cities in northern, eastern, and central Connecticut. The 959 area code is an overlay for the 860 region, serving Hartford, Manchester, New London, and surrounding areas.
Looking at the prefix number — the three digits after the area code — can narrow things down even further. Certain prefixes are unique to specific neighborhoods, towns, or local exchanges. This extra detail is useful if you’re doing a Connecticut cell phone lookup, landline lookup, or trying to verify an unfamiliar caller with a Who Called Me Connecticut search.
Understanding these patterns can help you:
- Verify a caller’s location before you answer the phone.
- Recognize and identify Connecticut numbers you’ve never seen before.
- Investigate suspicious texts, spam calls, robocalls, or telemarketing from Connecticut area codes.
- Use the Connecticut phone directory or a Connecticut reverse phone search tool to uncover the name, address, carrier, and public records linked to the number.
In the next section, you’ll find a detailed reference for Connecticut’s largest cities, their assigned area codes, and the most common prefix numbers in each location. This guide is designed to help you perform accurate Connecticut phone number lookups, verify Connecticut area codes, and determine whether a call is genuinely local or potentially spoofed.

🔍 How to Trace the Owner of a Connecticut Phone Number for Free: Step-by-Step Guide
Got an unfamiliar Connecticut phone number calling or texting you? Whether it’s a free 203 reverse lookup for a New Haven landline, a free 959 phone number search for a Hartford caller, or a free 475 area code check from Bridgeport, understanding how Connecticut phone numbers are structured can give you valuable clues before you even run a full search.
By breaking down the area code, prefix number (central office code), and subscriber number, you can often narrow a call’s origin to a specific city — and sometimes even the neighborhood. This free Connecticut phone lookup guide will show you how to read a phone number using the North American Numbering Plan (NANP) and combine it with a free Connecticut reverse phone lookup tool for the most accurate results.
🌎 Country Code
All U.S. phone numbers, including those from Connecticut, begin with the country code +1 when dialed from abroad. This instantly confirms the call is U.S.-based, helping you filter out international spam for free before wasting time on it.
Example: +1-203-XXX-XXXX. The +1 shows it’s a U.S. number. In this case, the 203 area code covers New Haven, Stamford, and Bridgeport, making a free New Haven phone number lookup the logical next step.
📍 Area Code (NPA – Numbering Plan Area)
The first three digits after the country code are the area code, which identifies the general region of the call. Connecticut has three primary area codes:
- 203 Area Code – New Haven, Bridgeport, Stamford, southwestern Connecticut
- 475 Area Code – Overlay for the 203 region
- 959 Area Code – Overlay for the 860 region, including Hartford, Norwich, and Willimantic
- 860 Area Code – Hartford, New London, Torrington, and much of central and eastern Connecticut
Example: 860-555-XXXX. The 860 area code points to Hartford and surrounding areas, making a free Hartford phone lookup the best move to confirm the caller’s identity.
🔢 Prefix Number (NXX – Central Office Code)
The next three digits after the area code are the prefix number, which is assigned to a specific city, neighborhood, or phone carrier within that area code. When paired with the area code, this can help you pinpoint the number’s likely origin for free before running a full search.
Example: 203-865-XXXX. Prefix 865 is associated with New Haven, so using a free New Haven reverse phone search could confirm who’s calling.
Pro tip: Suspect a spoofed call? Compare the prefix against legitimate Connecticut exchanges using a free Connecticut phone prefix directory to see if it matches the claimed location.
🔐 Subscriber Number
The last four digits of a phone number are called the subscriber number. These digits identify the specific phone line assigned to a person or business.
On their own, subscriber numbers don’t reveal a location — but when combined with the area code and prefix number, they make up a complete phone number that can be searched to return exact results.
Example: 475-201-8427.
- 475 = Area Code (Bridgeport/New Haven overlay).
- 201 = Prefix Number (specific to part of Bridgeport).
- 8427 = Subscriber Number (unique to this line).
Together, this full number can be entered into a free Connecticut reverse phone lookup to find the caller’s name, carrier, and public records.
