The 862 area code is Northern New Jersey’s overlay of 973 — the same Newark, Paterson, Clifton, Wayne, and Morristown territory across Essex, Passaic, Morris, and Sussex counties, served by a second set of digits since December 29, 2001. An 862 number and a 973 number are interchangeable in coverage and cost.
An 862 popping up cold is usually nothing more exotic than a newer North Jersey line — the code has served as the region’s fresh-number pool since 2001. What three digits can never establish is who is actually dialing.
The 862 cheat sheet
| 862 | Verified detail |
|---|---|
| Serving since | December 29, 2001 |
| Origin | An all-services second code over 973’s full footprint — not one number changed |
| Parent lineage | 973, cut from 201 in 1997; 201 was New Jersey’s original 1947 code |
| Major cities | Newark, Paterson, Clifton, Morristown, Newton |

| Projected exhaust | Q3 2052 (NANPA, April 2026) |
Is 862 a legitimate New Jersey area code?
It is — and the doubt it attracts is mostly a function of its age. NANPA assigned 862 on April 2, 2001 as an all-services overlay of 973, and it has covered the same four-county stretch of Northern New Jersey ever since. Anyone whose contacts were saved in the 973 era can go months without seeing the younger code, then meet it three times in a week when a school office, a pharmacy, and a plumber all happen to hold newer lines.
What no area code can vouch for is the person dialing. Spoofing smuggles any three digits onto a display, 862 included, and a ported 862 mobile may answer from anywhere in the country. Verify the caller rather than the code: an institution that genuinely holds the number will also pick up its published one.
Ordered in March, dialing by December
The paper trail runs unusually tight for a numbering project. On March 19, 2001, the New Jersey Board of Public Utilities ordered all-services overlays onto 201, 973, and 732 in a single stroke; NANPA’s database logs 862’s assignment two weeks later, on April 2; and Planning Letter PL-277, dated May 8, 2001, published the pairings — 551 over 201, 862 over 973, 848 over 732.
The dialing plan then moved faster than the code itself. Permissive dialing opened July 1, 2001, when seven, ten, or 1-plus-ten digits all completed a local call, and at 12:01 a.m. on December 1, 2001, ten digits became the rule across all three parent codes. By the time 862 entered service on December 29, the region had already spent four weeks dialing as though it existed. Overlays run in that order on purpose — our area code explainer covers why the dialing change has to land before the second code can.
Carriers had their own homework. PL-277 directed every domestic and international carrier to have the new codes activated throughout their networks before November 15, 2001 — the day recorded test announcements opened, 862’s on 862-321-8378, whose last four digits spell TEST on a keypad. The line stayed up through July 1, 2002.
The footprint under two codes
The map attached to PL-277 draws one shape for both codes, spanning Essex, Passaic, Morris, and Sussex counties. Newark and the Oranges hold down the southeast corner, Paterson, Clifton, and Passaic line the river, Wayne and West Milford climb into the highlands, Morristown, Madison, and Dover cross the office belt, and Newton, Sparta, and Montague run the ridge country to the New York line.
The edges misbehave the way area code edges always do — a handful of towns beyond the four counties answer on the pair’s exchanges, because code boundaries follow rate centers rather than county lines, and the parent code’s guide walks those oddities town by town.
Newark gives the pair its center of gravity: New Jersey’s largest city and the port-and-airport engine of the state’s north. The deeper economic biography of this territory lives in the 973 guide, which had a four-year head start on collecting it.
Dialing from the 862/973 pair today
Inside the footprint the rule is ten digits, full stop — NANPA’s dialing-plan record makes calls within the 862/973 pair 10D whether local or toll, with carriers free to accept the 1-plus-ten form as well. Cross into any other code, next-door 201 included, and the call takes 1 plus ten digits.
The 2001 conversion also excused North Jersey from the 988 scramble. Planning Letter PL-556 — January 8, 2021, PL-544’s successor in the series — catalogued the 82 area codes that still allowed seven-digit dialing while hosting a 988 prefix and had to convert before the crisis line opened nationwide in 2022. New Jersey’s two entries were 856 and 908. The 862/973 pair, ten-digit for two decades by then, had nothing to change.
The last New Jersey pool to empty
NANPA’s April 2026 exhaust analysis, drawn from NRUF and central-office code data as of March 1, gives 862/973 until the third quarter of 2052 — seven quarters more runway than the October 2025 study allowed, a push the report’s notes credit to softer demand, past and forecast. A correction sheet dated July 6, 2026 revised four Texas entries, nothing more, so the New Jersey date stands.
Stand the state’s codes in exhaust order and the overlay pair finishes last: 856 empties first, in early 2035, then 908 in 2039, 609 with its 640 overlay in 2046, the 201/551 pair in 2048, and 732/848 in 2051 before 862/973 closes the line in 2052. The database carries no jeopardy flag for the pair, NANPA’s relief-status report lists no New Jersey project, and our NPA-NXX guide shows how prefix counts turn into dates like these.
Working a North Jersey number
Sales and service teams calling into Essex, Passaic, Morris, or Sussex county get the same reception from either code — recipients read both as home. The measurable lift a hometown display earns is documented in our local presence dialing research; which of the two codes delivers it is a matter of rate-center inventory on order day.
SIPNEX carries direct FCC authorization — a licensed carrier, not a reseller — and stocks DID numbers across North Jersey rate centers in both 862 and 973 as inventory allows. Numbers land on your PBX or dialer over SIP trunking, outbound calls go out under A-level attestation from SIPNEX’s own STIR/SHAKEN certificate, and toll-free service runs on the company’s RespOrg registration.
862 numbers, explained
When did the 862 area code go into service?
December 29, 2001 — the same day as 551 and 848, New Jersey’s other two original overlays. The state’s Board of Public Utilities ordered relief for 201, 973, and 732 on March 19, 2001, NANPA published the assignments in Planning Letter PL-277 that May, and mandatory ten-digit dialing arrived December 1 — four weeks before the first 862 number could be issued.
Which North Jersey towns share the 862 area code?
Every town 973 serves — the two codes are one footprint. Newark, Paterson, Clifton, Passaic, Wayne, Morristown, Dover, Madison, Newton, and Sparta all sit inside it, across Essex, Passaic, Morris, and Sussex counties, plus a few edge towns beyond the county lines. An 862 caller is as thoroughly local as a 973 one.
Why did my new number come up 862 instead of 973?
Because your carrier drew it from the younger of the two North Jersey pools. Fresh 973 stock varies by rate center after nearly three decades of assignments, and where a block isn’t on hand, new numbers open under 862 — same territory, same rates, no practical difference beyond the digits themselves.
Are ten digits required to dial 862 numbers?
Yes — every call within the 862/973 footprint takes all ten digits, and calls to any other area code take 1 plus ten. It has been that way since December 1, 2001, which is why Planning Letter PL-556, the 988-driven conversion list of 2021, names 856 and 908 as New Jersey’s only entries: this region was twenty years ahead of it. Carriers may also accept the 1-plus-ten form on calls within the pair.
How long will 862 numbers stay available?
Decades — NANPA’s April 2026 forecast runs the 862/973 prefix pool into the third quarter of 2052, the latest date in New Jersey. The July 2026 revision cycle touched Texas entries only, no jeopardy declaration or relief docket exists, and North Jersey DID inventory in both codes can be provisioned now.
Either set of digits buys the same North Jersey welcome. SIPNEX issues 862 and 973 DIDs under direct FCC carrier authority, terminates them on whatever PBX or dialer you already run, and puts A-level attestation on every call it sends from its own STIR/SHAKEN certificate — contact SIPNEX, review current rates, or call (833) 665-2220.
