This New Jersey address generator creates a real-looking but fictional New Jersey address with a valid NJ ZIP code. The city is set to Newark and the ZIP is a real code issued in New Jersey, so the address is internally consistent with New Jersey (NJ) even though the street name and house number are invented and belong to no real residence.
It is ideal for testing shipping forms, address validation and region-specific features that need a believable New Jersey address, or for keeping your real address private when a site only needs a plausible one. The phone, name and other fields round out a full, fictional US profile.
Real New Jersey ZIP codes run from 07001–08989, and common NJ area codes include 201, 609, 732, 973. When you need a random New Jersey address whose fields agree with each other, this generator pins the 071xx Newark range — the reference table below lists real example ZIPs to compare against.
All data is fictional. The address points to no real occupant, the ID field is a masked test placeholder, and card numbers are sandbox values valid in format only — keep generated data to testing and privacy, never fraud.
Two metropolitan postal geographies inside one small state.
New Jersey's 723 postal codes sit under 20 three-digit prefixes that split cleanly into two families. The 070 to 079 block covers the northern counties in the New York metropolitan orbit; the 080 to 089 block covers the southern half, which looks to Philadelphia. The largest single prefix is 080 around Cherry Hill — the southern half, not the northern one most people picture when they think of New Jersey.
That split is the reason a New Jersey fixture set has to span both halves rather than sampling "a few New Jersey ZIPs". Two addresses ninety minutes apart can sit in different carrier zones, different sorting facilities and different metropolitan tax and delivery arrangements, in a state small enough that a test author assumes one of everything will do. It is the compact version of the problem Texas has at scale.
The density figure is the other useful one. New Jersey's codes carry 582 distinct USPS place names across 21 counties — about 34 postal codes per county, near the top of the national range, against six or seven in the plains states. Dense place naming means the city line in a New Jersey address is usually a municipality rather than a neighbourhood, which is the opposite of the California case where a place name is often neither.
One thing New Jersey does not do is break the prefix rule: none of its 20 prefixes reaches into another state. That makes it a good control fixture to sit beside the six that do — Connecticut and Washington DC among them — when you are testing whether a validator treats prefix-to-state as a rule or an absolute.
