Area code 959 — Northern and eastern Connecticut
First announced in August 1999 and then shelved for fifteen years, because the 860 pool drained far more slowly than anyone had forecast. It finally went into service in 2014 over exactly the same territory, which makes a 959 number as local to Hartford as an 860 one — simply newer.
New numbers available in 959Area code 959 covers northern and eastern Connecticut, sharing every street with 860. It is the newer of the two and the more available.
Its unusual history is worth knowing if you are comparing the pair: it existed as an approved plan for longer than most area codes have existed at all.

How 959 came about
An overlay announced, deferred, deferred again, and eventually switched on a decade and a half later.
- August 28, 1995The territory is createdConnecticut splits. 860 takes the northern and eastern half of the state, leaving 203 with the southwest. The ground 959 would eventually cover is defined here.
- August 1999An overlay is announcedThe Department of Public Utility Control, the predecessor to today’s PURA, announces 959 as an overlay on 860. Forecasts at the time suggest the older code is close to exhaustion.
- 1999–2014Fifteen years on paperThe forecasts prove wrong. 860 depletes far more slowly than projected, and implementation is deferred over and over. The code remains approved but unused for a decade and a half.
- November 14, 2009Ten-digit dialling anywayTen-digit dialling is made mandatory across the 860 territory in preparation for an overlay that will not arrive for another five years — the practical cost of a plan that kept being postponed.
- August 30, 2014Finally in service959 goes live under a PURA order, covering exactly the same geography as 860. Existing customers keep their numbers unchanged; new lines and transferred service can receive either code.
Which code should you choose?
The two Hartford-area codes are the same place. The choice is between familiarity and supply.
| Code | Since | What it gives you |
|---|---|---|
| 860 | 1995 | The code people picture for Hartford; long established |
| 959 | 2014 | Same territory, newer, with more numbers to choose from |
| 203 | 1947 | Wrong half of the state — southwestern Connecticut |
| 475 | 2009 | Also southwestern; the overlay on 203 |
Either Hartford code is equally local. 959 is the one to ask for if you want a say in the last four digits.
What people get wrong about 959
Is 959 used for spam calls?
959 is spoofed alongside 860, and the reported patterns are the same because the two codes are the same place: impersonation of Eversource threatening imminent disconnection, and health-insurance phishing that leans on Hartford’s insurance identity. Being the newer and less familiar of the pair gives 959 slightly less disguise value, which is a comment on fraudster incentives rather than any protection. Caller ID is a display field, not proof of origin — call any organisation back on a number you looked up yourself.
Area code 959 FAQ
What area code is 959?
959 covers northern and eastern Connecticut, including Hartford and its suburbs. It is an overlay on 860 and covers exactly the same territory.
Is 959 the same area as 860?
Yes, precisely the same. An overlay adds capacity to a territory rather than taking a piece of it, so a 959 number is as local to Hartford as an 860 one.
When did the 959 area code start?
It went into service on 30 August 2014, though it had been announced as far back as August 1999. The fifteen-year gap is because 860 depleted much more slowly than forecast, so implementation was repeatedly deferred.
Why does Connecticut need four area codes?
Two pairs cover two halves of the state: 860 and 959 in the north and east, 203 and 475 in the southwest. Each pair is a geographic code plus an overlay added when the original ran short.
Can I get a 959 number with a memorable ending?
Your odds are better than on 860. Having issued numbers only since 2014, 959 holds the larger pool of unassigned numbers in the Hartford area, so patterned endings are more likely to be free.
Do I need a Connecticut address to hold a 959 number?
No. Numbers are assigned by area code rather than billing address, so a business anywhere can hold one and route calls to wherever its team actually works.
What time zone is the 959 area code in?
Eastern, identical to 860 since it is the same territory. UTC−5, or UTC−4 in summer.
Is 959 a legitimate Connecticut area code?
Yes. It has been in service since August 2014 as an overlay on 860, covering exactly the same territory. It is unfamiliar mainly because it is newer and less widely issued.
How do I get a 959 number?
Search 959 inventory — the newer of the two Hartford codes and the one with room — then set routing before the number is printed anywhere.
Which counties does 959 cover?
The same six as 860: Hartford, Litchfield, Middlesex, New London, Tolland and Windham. An overlay shares its territory exactly rather than taking a piece of it.
