Area codes serving Newark
Newark sits in New Jersey, part of the Northeast region and the Eastern Time zone. Its numbers are spread across an overlay of 2 codes that all cover the same ground: 862, 973.
The original code is 973 (in service since 1997). As the area ran low on numbers, regulators added overlay codes on top instead of splitting the city, so longtime residents kept their numbers while new lines received a newer code.

How to pick an area code for a new number
When you activate a new line in Newark, the carrier assigns whichever code has numbers available — you usually can't choose. If a specific code matters to you (for example the prestige of 973), ask the carrier whether any blocks remain, or request a number transfer. All codes here dial identically and cost the same.
