The demand for 860 phone numbers is so high that they are expected to run out by the end of the year.
Later this year, the 959 area code will be available for your dialing needs, according to the state Public Utilities Regulatory Authority.
It will be available in the region that now uses 860.
If you already have an 860 number, you will not need to change it because existing numbers will not change.
The new area code goes into effect on August 30. After that date, customers asking for new service or an additional line will get a 959 number.
You will still have to dial the area code, then the telephone number for local calls and 1, followed by the area code and telephone number for long distance calls.
Local calling areas will remain the same and prices for calls and coverage areas will not change because of the so-called overlay number.
This will not affect three-digit service numbers, including 911, 211, 411 and 811.
If you have questions about the area code addition, call your carrier or check PURA's website for updates.
According to the North American Numbering Plan Administration, the 959 area code was reserved for Connecticut in 1999 but wasn't needed until now.
