Time zone

Area code 959 lies in the Eastern Time Zone.


It was created in 2014. Currently serves as an overlay to 860. Area code 860 was created on August 28, 1995, as a result of area code 203 split. While area code 203 was the originally based area code in NANP to serve Connecticut.

With the passage of time, telecommunication needs also increased in the area. Therefore, creating the demand of new area code to fulfill the needs.

As of above scenario, The Public Utilities Regulatory Authority proposed an area code overlay in August 1999, for numbering plan area (NPA) 860 thereby adding the new area code 959. This proposal did not implemented at that time and postponed instead for nearly a decade due to following reasons.

  • The overlay plan proposed within two years. Activation date for 959 had not announced as of August 30, 2011.
  • In March 2009, the activation date for both overlay plans announced.
  • On December 12, 2009 the 203/475 overlay would be activated, while the 860/959 overlay would be activated by 2011.

On August 27, 2013, the NANPA dispensed the information that the area code 959 would go into effect on August 30, 2014. Whereas, the first phone numbers distributed in December 2015. The Public Utilities Regulatory Authority announced the new area code, introduced in the calling region served by the area code 860. In short, the existing 860 area code exhausted because the demand for more phone numbers created.
