The 772 area code covers Florida’s Treasure Coast — Port St. Lucie and Fort Pierce in St. Lucie County; Stuart, Jensen Beach, Indiantown, and Hobe Sound in Martin County; Vero Beach and Sebastian in Indian River County; plus a southern sliver of Brevard. Split from area code 561 on February 11, 2002, it has never carried an overlay.
An unfamiliar 772 call is as likely a Port St. Lucie contractor or a Vero Beach clinic as a spoofed display — the three digits record where a number was issued, never who is dialing through it.
772, boiled down
| Fact | Detail |
|---|---|
| First morning | February 11, 2002, at 12:01 a.m. Eastern |
| Split from | 561, itself a 1996 offshoot of 407 |
| Overlay record | None — one code for the whole territory since launch |
| Coastal anchors | Port St. Lucie, Fort Pierce, Stuart, Vero Beach, Sebastian |
| Local habit | Local calls still connect with seven digits |
| Forecast | Third quarter of 2102 (NANPA, April 2026) |
On paper this is one of NANPA’s quietest files: one planning letter created the code, no letter has touched it since, and the dialing plan is unchanged from launch day. The interesting parts hide in the dates — a split that sat approved but frozen for thirteen months, and an exhaust forecast that just leapt sixteen years in a single study, clear into the next century.
Three counties and a sliver of a fourth
The map attached to NANPA Planning Letter PL-311 draws the split line just north of Jupiter. Everything above it went to the new code — the Hobe Sound, Stuart, Indiantown, Jensen Beach, Port St. Lucie, Fort Pierce, Vero Beach, and Sebastian rate centers — while Jupiter and everything south of it stayed with 561.
That works out to Martin, St. Lucie, and Indian River counties end to end, with a small piece of southern Brevard County riding along at the northern tip; the rest of Brevard, the Space Coast, dials 321. PL-311 itself calls the territory what locals call it — the Treasure Coast — and the name has effectively belonged to these three digits ever since.
Approved in 2000, shelved until 2002
The pedigree runs four generations deep. 305 covered all of Florida from 1947; 407 took Orlando and the Atlantic coast north of Broward in April 1988; 561 arrived on May 13, 1996 to carry everything from Boca Raton up past Vero Beach; and six years later the northern half of that stretch became 772 — NANPA’s database still lists 561 as its parent.
The regulatory rhythm was odd, though. The Florida Public Service Commission picked the remedy early — Order No. PSC-00-1937-PAA-TL of October 6, 2000, in Docket No. 990456-TL, specified a two-way geographic split — and then withheld implementation. The plan sat for thirteen months until a procedural order dated November 1, 2001 — Order No. 01-2145-PCO-TL — finally set the dates, and NANPA published PL-311 three weeks later, on November 21, 2001.
The switch flipped at 12:01 a.m. Eastern on February 11, 2002. For nine months a call dialed with either code still landed in the new territory; permissive dialing ended on November 11, 2002, after which misdials reached an intercept recording kept on until at least February 9, 2003. Carriers could verify routing in advance against a test number available no later than January 11, 2002 and retired on February 11, 2003 — (772) 227-2002, its last four digits matching the cutover year.
Why can 772 still dial seven digits?
Because nothing ever forced the change. Splits preserve short dialing — PL-311’s post-split plan kept local calls inside the home code at seven digits, with ten digits for local calls into a neighboring code and 1-plus-ten for toll — and since no overlay has ever been layered on the Treasure Coast, the usual trigger for ten-digit dialing never fired.
The national trigger passed it by as well. When Planning Letter PL-556 (January 8, 2021), the update that retired PL-544, named the 82 area codes that had to abandon seven-digit dialing so 988 could reach the crisis line, Florida’s four entries were 321 in its Brevard-only portion, 352, 561, and 941. 772 stayed off the list because 988 was not in use as a prefix there.
The result is a quiet reversal of seniority. Parent 561 lost seven-digit dialing on October 24, 2021 and has shared Palm Beach County with the 728 overlay since March 10, 2023; the code it spun off still reaches a neighbor with seven digits, and NANPA’s current database — dated mid-August 2026 — records the plan unchanged.
A forecast that reads 2102
NANPA’s NPA Exhaust Analysis for April 2026 — the 2026-1 edition, built on numbering data through March 1 — sends 772’s prefix supply all the way to the third quarter of 2102. That is the latest date in Florida by a distance: the runner-up, Broward’s 754/954 pair, reaches the fourth quarter of 2065, almost thirty-seven years sooner, and the state’s thirteen other forecast complexes all land earlier still.
The date is also brand new. The October 2025 study had said third-quarter 2086; the April revision pushed the forecast out sixty-four quarters — sixteen years, the largest move of any Florida entry in the study — on what NANPA logs as reduced historical and projected demand. The July 6, 2026 correction sheet that followed revised exactly four complexes, all of them in Texas, and left every Florida date standing.
None of the relief machinery exists for 772: no jeopardy declaration, no relief planning, no second code in waiting. If that ever changes, relief would arrive as an overlay on the same map rather than another split — our area-code playbook walks through why the industry switched approaches.
What Treasure Coast digits do for a business
For a sales or service operation the code is a clean unit: one set of digits reads local from Sebastian down to Hobe Sound — every anchor town of three counties at once. A display customers recognize gets answered more often, and the measured difference is the subject of our local presence dialing guide.
The digits alone certify nothing, though. Caller ID spoofing can scrawl 772 on traffic from anywhere on earth, so durable caller trust comes from cryptographic signing at the carrier holding the number, not from the number on the screen.
SIPNEX supplies that layer as an FCC-licensed carrier — direct authorization, not resale. Local DID numbers are issued against individual rate centers, Port St. Lucie to Sebastian as inventory allows, and delivered over SIP trunking to whichever PBX or dialer the desk runs. Every outbound call gets its A-level signature from SIPNEX’s own STIR/SHAKEN certificate, and toll-free service rides the same company’s RespOrg registration when a campaign needs both sides covered.
Treasure Coast questions, answered
Which Florida counties does the 772 area code cover?
Martin, St. Lucie, and Indian River counties, plus a small southern piece of Brevard County. The anchor communities are Port St. Lucie, Fort Pierce, Stuart, Jensen Beach, Vero Beach, Sebastian, Indiantown, and Hobe Sound. The boundary with 561 sits just north of Jupiter — Hobe Sound dials 772 while Jupiter dials 561 — and the rest of Brevard County, beyond the sliver, dials 321.
When did 772 split from the 561 area code?
At 12:01 a.m. Eastern on February 11, 2002, under NANPA Planning Letter PL-311. The Florida Public Service Commission had specified the two-way split on October 6, 2000 — Order No. PSC-00-1937-PAA-TL in Docket No. 990456-TL — but withheld implementation until a November 1, 2001 order set the dates. Either code completed calls into the new territory until permissive dialing ended on November 11, 2002.
Does the 772 area code still allow seven-digit local dialing?
Yes — local calls inside 772 still connect with seven digits, per NANPA’s current dialing-plan record. Neither trigger for ten-digit dialing ever reached the Treasure Coast: no overlay has been added, and 772 was absent from Planning Letter PL-556’s list of 82 codes converted for the 988 crisis line, which named 321 (its Brevard-only segment), 352, 561, and 941 for Florida. Local calls into a neighboring area code take ten digits, and toll calls take 1 plus ten.
How long will 772 area code numbers last?
Into the next century, on the current forecast. NANPA’s April 2026 NPA Exhaust Analysis projects 772’s prefix supply reaching the third quarter of 2102 — the latest date among Florida’s fifteen forecast complexes, and sixty-four quarters later than the October 2025 study said, on reduced demand. The July 6, 2026 revision changed only four Texas entries, and NANPA’s database shows no jeopardy and no relief planning for 772.
Can a business outside Florida use a 772 area code number?
Yes. Numbers attach to rate centers and carriers, not street addresses, so a team anywhere can hold 772 DID numbers issued in Port St. Lucie, Fort Pierce, Stuart, or Vero Beach and route them over SIP trunking to any office or dialer. The line rings and displays exactly like one installed on the Treasure Coast, provisioned under SIPNEX’s own FCC carrier authorization.
Three counties answer to one set of digits, and the supply runs to 2102 — a Treasure Coast presence is a provisioning order, not a project. SIPNEX issues 772 numbers by rate center under its own FCC license, hands them off over SIP, and signs every call at A-level on its own certificate. Pricing is published, (833) 665-2220 gets you a live answer, and the contact form reaches the same team in writing.
