New Jamaica area code 658

The Caribbean island country of Jamaica uses the North American Numbering Plan and its area code within the NANP is 876. On September 15, 2016 a new area code was announced by Jamaica’s telecom regulator as a relief method for existing 876 area code. Starting next year in November the new 658 area code will also cover the entire island and, as a result 10 digit dialing will be used for all local calls.

Key dates

  • May 31, 2018 – start of permissive 7/10 digit dialing period (all telephone calls on the island may be dialed using either 7 or 10 digits)

New State of New Jersey area code 640

From 1958 to 1999 the southern part of New Jersey was served by area code 609. In 1999 the Numbering Plan Area 609 was split into two with the new area code 856 covering the south-western portion of NJ. Today, once again, a relief plan is needed for area code 609. The approved relief method is an overlay code which will serve the same south eastern NJ area currently covered by NPA 609. The new area code 640 will enter service next year in September. As a result of the newly created overlay complex 609/640, 10 digit dialing will be mandatory for all calls within its borders.

Key dates

  • January 20, 2018 – permissive 10 digit dialing begins (10 digit dialing is encouraged)
  • August 18, 2018 – mandatory 10 digit dialing begins
  • September 17, 2018 – area code 640 enters service

7 digit calls between 609 and 856 to be eliminated

Since the 1999 split of NPA 609 some calls between area codes 609 and 856 could be dialed using 7 digits. With the above changes these protected NXX codes will also be eliminated and regular 1+10 digit dialing will be required for all calls between the two NPAs.

San Diego county area codes 619 and 858 boundary removal

California area codes 619 and 858 currently cover the southern and northern parts of San Diego respectively, including some of its suburbs.

Key dates

  • November 11, 2017 – permissive 1+10 digit dialing begins (1+10 digit dialing is encouraged for all calls)
