The 860 area code in the USA is located in the state of Connecticut, covering the vast majority of the state, including the capital city of Hartford and the northern and eastern regions.
This article provides a complete overview of the 860 area code, including its geographic coverage, time zone, major cities, and details about its accompanying overlay code.
Location and Coverage of the 860 Area Code
The 860 area code is designated for the majority of the US state of Connecticut, situated in the northeastern United States (New England region). It operates as an overlay with the 959 area code, meaning that both codes serve the exact same geographic area, and all local calls require 10-digit dialing.
Key Geographic Regions Covered
The 860 area code serves the following six counties (or portions thereof):
- Hartford County
- New London County
- Litchfield County
- Tolland County
- Middlesex County
- Windham County
The only part of Connecticut not covered by the 860/959 complex is the southwestern region (primarily Fairfield and New Haven Counties), which uses the 203/475 area code overlay.
Major Cities in the 860 Area Code
The following major cities and communities are served by the 860 area code:
| Major City | County | Key Industries |

- Daylight Saving Time: Eastern Daylight Time (EDT) or UTC-4
History and Overlay: The 959 Area Code
The 860 area code was established in 1995 as a split from Connecticut’s original sole area code, 203, which had served the entire state since the North American Numbering Plan (NANP) was created in 1947.
Due to the depletion of available phone numbers, the state introduced an overlay area code, 959, in 2014.
What the 860/959 Overlay Means
When an overlay is implemented:
- Shared Territory: Both 860 and 959 cover the identical geographic area.
- Mandatory 10-Digit Dialing: Regardless of whether you are calling a number with an 860 or a 959 prefix, all local calls within this region must include the 3-digit area code plus the 7-digit number (10 digits total).
Is the 860 Area Code Associated with Scams?
The 860 area code itself is a standard, legitimate area code in the USA and is not inherently a scam code (unlike certain international codes like 809 or 268, which are common for one-ring scams).
However, residents in the 860 area code, like those across all domestic US area codes, are frequently targeted by scammers using a technique called Caller ID Spoofing.
Understanding Caller ID Spoofing
- What it is: Scammers intentionally manipulate the Caller ID displayed on your phone to make the incoming call appear to be originating from a local number (in this case, an 860 number) or even a number that resembles your own.
- Why it’s used: This tactic is used because people are far more likely to answer a call from a number they perceive as local or familiar.
- Common Scams: These spoofed 860 calls are often associated with classic scams, such as car warranty expirations, government/IRS impersonation, or package delivery notifications.
Actionable Tip for Safety
Do not answer or return calls from 860 numbers that you do not recognize. If a legitimate contact needs to reach you, they will typically leave a voicemail. If the caller is from a government agency or business, look up their official contact number and call them back directly to confirm their identity.
Frequently Asked Questions (FAQ)
- What is the difference between the 860 and 203 area codes in Connecticut?
The 860 area code covers the northern, eastern, and central parts of Connecticut, including Hartford. The 203 area code (overlaid with 475) covers the southwestern part of Connecticut, including major cities like Bridgeport, New Haven, and Stamford.
- Is 860 a mobile or landline area code?
The 860 area code is assigned to both mobile (wireless) and landline (wireline) phone numbers. In modern telecommunications, area codes no longer distinguish between mobile and fixed lines; they simply indicate the geographical region where the number was first issued.
- Do I need to dial “1” before calling an 860 number?
For most modern cell phones and Voice over IP (VoIP) services, you generally do not need to dial the “1” preceding the area code for long-distance calls within the US. However, since the 860 area code is part of an overlay complex (860/959), you must always dial all 10 digits (860 or 959 plus the 7-digit number) even for local calls within the same area code.
