Newark ZIP codes: US ZIP code list for Newark, New Jersey (NJ)

Quick answer

Newark, New Jersey has 9 US ZIP codes, running 07102 to 07114 inside Essex County. Each carries the same 6.625% combined sales tax rate. ZIP boundaries are postal delivery routes, not tax boundaries — a code that crosses a city or district line can hold more than one rate, so destination-based sellers should validate by full street address.

Newark ZIP code footprint

How Newark's ZIP footprint compares with national norms.

9 ZIP codes are listed for Newark, covering a population of 305,344. They span 13 numbers, 07102 through 07114. The median covered metro on this site lists 12 codes; Newark ranks 69 of 94 by count. Large metros carry more codes because USPS splits a delivery area once carrier volume outgrows one route cluster, not because the city is geographically bigger.

All 9 codes share the 071 prefix. That first trio is the sectional center facility — the USPS plant that sorts mail for the region — so every piece addressed to Newark passes through one facility. The range runs 07102 to 07114.

ZIP boundaries are carrier routes, not city limits. USPS redraws them when delivery volume shifts; New Jersey redraws tax and municipal lines on a different schedule entirely. A Newark mailing address does not prove an address sits inside Newark city limits, and a single code can straddle the boundary.

Why ZIP-based rate lookup is unreliable

USPS redraws ZIP codes when carrier routes change. Tax jurisdictions move with annexations, county lines and voter-approved districts. The two never line up. In New Jersey, even without local add-ons, remote sellers should validate the full delivery address against the New Jersey Division of Taxation lookup at the time of sale.
