The 409 area code is the upper Texas coast — Beaumont, Port Arthur, Orange, and Galveston, with Texas City, Nederland, Vidor, Silsbee, and Jasper inside the same lines — split from Houston’s 713 on November 1, 1982 and never overlaid. Local calls take ten digits, and the code has stood alone since 936 and 979 were carved away in 2000.
Who is on the other end of a 409? Usually something industrial or institutional — a refinery contractor, a port office, a Galveston medical campus, a school district — but the code narrows the caller to a stretch of coastline and no further.

Texas’s seventh code, twenty-five years after its sixth
NANPA’s NPA database records 409 assigned and placed in service on the same date, November 1, 1982, with 713 named as its parent. Texas had managed on six codes until then: 214, 512, 713, and 915 from the original 1947 map, 817 from 1953, and 806 from 1957. Nothing was added for twenty-five years — and when the drought ended, it was Houston’s code that gave up ground, surrendering everything outside the metro to the new 409.
The database lists no planning letter for that 1982 split; the only letters on 409’s record are PL-544 and PL-556, the 2020–21 pair about the 988 crisis line. What the split produced is easiest to read off the maps NANPA attached to Planning Letter PL-201 seventeen years later: a horseshoe wrapped around Houston on three sides, from the Louisiana line at the Sabine River, north through the piney woods past Nacogdoches, west to Bryan and College Station, and back to the Gulf at Bay City — with the Houston island in the middle marked 713/281/832, no change.
How the parent kept the coast in 2000
By late 1999 that horseshoe was running short of prefixes, and the Public Utility Commission of Texas approved a three-way geographic split. NANPA set it out in Planning Letter PL-201, dated December 6, 1999: Beaumont, Bridge City, Galveston, Groves, Hitchcock, Jasper, La Marque, Nederland, Orange, Port Arthur, Port Neches, Santa Fe, Silsbee, Texas City, and Vidor would retain 409. The piney woods — Conroe, Huntsville, Lufkin, Nacogdoches, and five more towns — became 936, and the Brazos Valley and the coast below Houston — Bryan, College Station, Lake Jackson, Bay City, Brenham, and their neighbors — became 979.
The clock ran on Central time. The split and its permissive dialing period began at 12:01 a.m. on February 19, 2000, when a 936 or 979 number could still be reached with the old 409 in front of it. Permissive dialing ended at 12:01 a.m. on August 5, 2000, after which calls dialed with the wrong code went to intercept. Carriers had a rehearsal line for each new code — 936-438-8378 and 979-270-0001, activated January 19, 2000 — and NANPA’s database logs both children assigned September 2, 1999 and in service February 19, 2000, each with 409 as parent.
The arithmetic is what makes 409 unusual. The parent kept its digits but lost most of its map: the timber country and the Brazos Valley left, and what stayed was the coast — the Golden Triangle, the Galveston Bay shore, and the timber counties up to Jasper and Newton. Three generations from Houston’s 1947 code, only the middle one stayed put.
Which cities does the 409 area code cover?
Start at the Louisiana line. Orange and Bridge City sit on the Sabine with Vidor just inland; Beaumont anchors the middle, with Nederland, Port Neches, and Groves strung toward Port Arthur and Sabine Pass on the Gulf. North of the refineries the code runs up through Silsbee, Kountze, and Woodville to Jasper, Kirbyville, and Newton — rate centers the PL-201 prefix listing keeps on the 409 side of the split line.
The other half is Galveston Bay. Galveston Island, Port Bolivar across the ferry, and the mainland towns of Texas City, La Marque, Hitchcock, and Santa Fe all carry 409, as do Anahuac and Winnie in Chambers County to the east. Every rate center keeps Central time. Houston’s five-code complex fills the west — 832 and its partners begin where 409 ends — 936 lies north, 979 southwest, and Louisiana is across the river. The rest of the state’s codes are laid out in our Texas area code directory.
The Orange prefix that ended seven-digit dialing
PL-201 fixed 409’s dialing plan in 1999: local calls inside the code on seven or ten digits, local calls into another code on ten, toll on 1 plus ten. That held for two decades, until the FCC’s Order FCC 20-100 — adopted July 16, 2020 and released the next day — designated 988 as the national suicide and crisis line and required ten-digit dialing wherever seven-digit calls and a 988 prefix coexisted.
409 qualified. On PL-201’s 1999 prefix listing, 409-988 is an Orange rate-center prefix, which is exactly the collision the order was written for. NANPA’s Planning Letter PL-544 (August 17, 2020) listed 83 such codes; PL-556 (January 8, 2021) superseded it at 82 after North Dakota’s 701 returned its 988 prefix and dropped off on January 7, 2021. 254, 361, 409, 806, 830, 915, and 940: those were the Texas lines, seven in a table that ran from Alaska to Vermont.
The schedule in PL-556 was national: permissive ten-digit dialing from April 24, 2021, mandatory from October 24, 2021, carrier enforcement cuts complete by July 15, 2022, and 988 live on July 16, 2022. NANPA’s database now shows 409 at ten digits for every local call, home code or neighboring, with 1 plus ten for toll and a leading 1 on local calls accepted at each provider’s discretion. The general mechanics of splits, overlays, and dialing plans are in our area code explainer.
One irony sits on the same map. 936 and 979, the codes cut from 409 in 2000, never appeared on PL-556 and still list seven-digit local dialing — the parent converted while both children kept the old habit.
Drifting toward 2051
NANPA’s 2026-1 NPA Exhaust Analysis (April 2026, built on NRUF and central office code data as of March 1, 2026) projects 409 running out of assignable prefixes in the fourth quarter of 2051. The October 2025 edition had said the third quarter of 2048; the forecast moved thirteen quarters later, and the study’s note attributes the shift to reduced historical and projected demand. How prefix consumption becomes a date like that is the subject of our NPA-NXX guide.
The trend is not a straight line. The April 2024 study printed the third quarter of 2045, the nearest date in the current report’s history; October 2024 said the second quarter of 2047, and April 2025 the second quarter of 2051. NANPA’s July 6, 2026 revision sheet then touched four Texas entries — 210/726, 361, 830, and 979 — and 979 alone gained nineteen quarters, from 4Q2068 to 3Q2073. 409 was not revised.
Nothing is pending on the regulatory side either. NANPA’s database has 409 flagged for neither jeopardy nor relief planning, and its relief planning status report dated August 30, 2026 runs to a dozen codes nationwide, with a single Texas entry: 956, where the industry was notified June 23, 2026 of a second-quarter 2029 exhaust. The upper coast has a quarter-century of paper runway.
What a 409 display buys you from Orange to Galveston
The 409 market answers to its own digits. A Houston number reads as out-of-town in Port Arthur, and a Dallas number reads worse; a 409 display is the local refinery supplier, the island contractor, the school district calling back. The answer-rate gap between strange digits and hometown digits is measurable on outbound campaigns, and our local presence dialing guide puts numbers on it. In a market where refinery turnarounds, port logistics, and Galveston tourism drive the calling calendar, that gap is real money.
Digits are not identity. Caller ID spoofing can stamp 409 on a call from anywhere, which is why the durable signal is applied at the carrier: SIPNEX operates under a direct FCC license and signs outbound calls at A-level attestation with its own STIR/SHAKEN certificate, provenance a spoofed display cannot fake.
The supply side is simple. SIPNEX provisions Texas DID numbers by rate center — Beaumont, Port Arthur, Orange, Galveston, Texas City, or any 409 exchange with open inventory — and delivers them into a PBX or dialer over SIP trunking sized for real call volume, with toll-free service available under SIPNEX’s own RespOrg registration.
What callers want to know about 409
Which cities and towns are in the 409 area code?
Beaumont, Port Arthur, Orange, and Galveston, plus the towns between them on the upper Texas coast. NANPA Planning Letter PL-201 names Bridge City, Groves, Hitchcock, Jasper, La Marque, Nederland, Port Neches, Santa Fe, Silsbee, Texas City, and Vidor as keeping 409 in the 2000 split, and its rate-center map adds Port Bolivar, Sabine Pass, Anahuac, Winnie, Kountze, Woodville, Kirbyville, and Newton. All of it runs on Central time.
When was the 409 area code created, and from what?
November 1, 1982, as a split of Houston’s 713 — NANPA’s NPA database dates both assignment and service to that day. It was Texas’s seventh area code and the first new one since 806 in 1957. The original 409 wrapped around Houston from the Sabine River to the Brazos Valley; the February 19, 2000 three-way split under PL-201 sent the piney woods to 936 and the Brazos Valley to 979, leaving 409 the coast.
Are local calls in the 409 area code seven or ten digits?
Ten digits, for every local call. Seven-digit dialing ended under NANPA Planning Letter PL-556 (January 8, 2021), which converted 82 area codes ahead of the 988 crisis line: permissive ten-digit dialing from April 24, 2021, mandatory from October 24, 2021. Toll calls take 1 plus ten digits, and NANPA’s database notes that a leading 1 on local calls is accepted at each provider’s discretion.
Will the 409 area code get an overlay?
Not on any current schedule. NANPA’s April 2026 exhaust analysis projects 409 lasting until the fourth quarter of 2051, thirteen quarters beyond the October 2025 forecast, and the July 6, 2026 revisions left it untouched. NANPA’s database shows neither a jeopardy declaration nor an open relief case, and 409 does not appear in the August 30, 2026 relief planning status report.
Who is likely calling from a 409 number?
Most often a business or institution on the upper Texas coast — refinery and port contractors, Galveston-area healthcare, county offices, school districts. The display alone settles nothing, because caller ID spoofing can attach 409 to a call from anywhere. If the call matters, hang up and dial back through a number published on the organization’s own site.
The upper coast picks up fastest for its own three digits, and SIPNEX can put them on your desk: 409 rate-center numbers from an FCC-licensed carrier, alongside every US market, with SIP built for dialer volume and each outbound leg carrying A-level attestation. Rates are on the pricing page; the contact desk handles written requests; (833) 665-2220 handles the spoken kind.
