Connecticut Area Codes Pieces of Information
The state of Connecticut is located in the northeastern United States and is bordered by Rhode Island to the east, Massachusetts to the north, and New York to the west. The capital of Connecticut is Hartford and its largest city is Bridgeport. The state has a population of over 3 million people.
The 203 area code is the original area code for the entire state of Connecticut. It was put into place in 1947. The 203 area code covers southwestern Connecticut, including the cities of Stamford, New Haven, and Greenwich.
The 860 area code is the second-oldest area code in Connecticut. It was created in 1995 as a split from the 203 area code. The 860 area code covers the rest of the state, including the cities of Hartford, Waterbury, and New Britain.
The format for writing telephone numbers in Connecticut is: (area code) xxx-xxxx. The first three digits of the phone number are known as the exchange code, and the last four digits are known as the subscriber number or line number. The exchange code is used to route calls to the correct telephone exchange, and the subscriber number is used to route the call to the specific line of that customer.
Area codes are assigned to specific geographic areas, so the area code you have will depend on what part of Connecticut you live in. If you need to find out what your area code is, you can use an online area code lookup tool or look it up in the phone book.
When dialing a phone number in Connecticut, you must always include the area code, even if it is the same as the one you are calling from. If you are making an international call from Connecticut, you will need to dial 011 + the country code + the phone number.
If you are making a long-distance call within the United States from Connecticut, you will need to dial 1 + the area code + the phone number.
To make a long-distance call to Connecticut from another country, you will need to dial 011 + 1 + the area code + the phone number.
Connecticut is part of the North American Numbering Plan (NANP), which means that its area codes are compatible with those in other parts of the United States and Canada. When calling from one NANP country to another, you do not need to dial an exit code. Just dial 1 + the area code + the phone number, as you would for any other long-distance call within the NANP.
