334 Area Code: Montgomery and the 483 Overlay

The 334 area code belongs to central and southeast Alabama — Montgomery, Prattville, Auburn, Opelika, Phenix City, Troy, Enterprise, Dothan, Eufaula, and Selma among its cities — and since February 23, 2026 it has shared every mile of that territory with the new 483 overlay, which is why local calls here now take ten digits.

Two milestones bracket this code’s three decades. Its first morning in 1995 changed what an area code could even look like, and its final seven-digit local call, dialed sometime before January 23, 2026, closed one of the longer stretches of old-fashioned dialing left in the country. Between the two sits a Gulf Coast divorce and a number supply that swung from months of runway to decades in a single forecast.

The birthday that broke the format

Alabama ran on a single code for forty-eight years before regulators split 205 and handed the state’s southern half — Montgomery, the Black Belt, the Wiregrass, and the coast at Mobile — to a newcomer. NANPA’s database records 334 assigned on January 26, 1994 and in service on January 15, 1995.

That date carries weight far beyond Alabama. Every code activated since 1947 had a 0 or 1 as its middle digit, a hard limit of electromechanical switching. January 15, 1995 was the day the plan finally put codes outside that pattern on the air — and it happened in two places at once. Washington’s 360, assigned five days before 334 in January 1994, entered service the same morning; its territory now sits inside the 564 overlay. Central Alabama and Puget Sound share a claim to the modern numbering era’s first dial tone.

Mobile checks out in 2001

Coastal growth forced the next cut. On October 2, 2000, the Alabama Public Service Commission approved a two-way geographic split of 334, announced in NANPA Planning Letter PL-254 — a letter whose cover is misdated January 2, 2000, a year before the schedule it publishes. Montgomery, Auburn, Dothan, and Demopolis kept 334; the southwest corner, Mobile and its Gulf shoreline included, became the new 251 at 12:01 a.m. Central on June 18, 2001.

The transition had unusual patience built in. Calls dialed with either code completed through January 7, 2002, wireless prefixes that predated the split got until February 12, 2003, and carriers could test their routing against 251-431-9020 from May 18, 2001. Whether a region gets a split like this or an overlay is a regulator’s choice — our area code guide explains what tips it.

One line in PL-254 mattered most for daily life: after mandatory dialing began, calls within each code stayed at seven digits. Losing the coast changed nobody’s habits in Montgomery.

Thirty-one years of seven digits

The nationwide push that ended seven-digit dialing almost everywhere else passed this code by. When the crisis line’s 988 shortcut forced conversions, NANPA’s PL-556 (January 8, 2021) listed the 82 codes where 988 was working as a local prefix — and Alabama’s only entry was 251, converted October 24, 2021. With no 988 prefix in use, central Alabama kept dialing seven.

So the habit ran from the code’s first morning in January 1995 to January 23, 2026 — thirty-one years and eight days. What finally ended it was not the crisis line but arithmetic: the prefix inventory underneath 334 was running out.

Docket 33429 sends in 483

By the time the commission acted, NANPA’s utilization forecasts had 334 exhausting in the third quarter of 2026 — the projection the PSC quoted in its March 21, 2024 announcement. The approval itself, in Docket No. 33429, carries a one-day wobble in the record: Planning Letter PL-626 dates it March 5, 2024, while the commission’s own release stamps it March 6. Either way, the remedy was an all-services overlay — 483 laid over the identical footprint, no existing number touched.

PL-626 (May 7, 2024) set the schedule and it held without revision: permissive ten-digit dialing from July 23, 2025, mandatory from January 23, 2026, and 483 in service on February 23, 2026, with routing verifiable against test number 483-483-1483 through March 23, 2026.

The letter also decided which digits people actually receive. Prefixes in 483 become assignable only after every assignable prefix in 334 is spoken for, so new Montgomery and Dothan numbers keep issuing from the 1995 code first. And in a small housekeeping flourish, the long-withheld 334-334 prefix itself was cleared for assignment once 483 went live.

Five months of runway became decades

NANPA’s October 2025 study still had 334 exhausting in the second quarter of 2026 — months away. The April 2026 edition, its data current to March 1 — six days after 483 lit up — reads third quarter of 2064 for the combined pair: a swing of 153 quarters, one of the largest in that entire report. Nothing in the July 6, 2026 revision list applied to Alabama — its four line items were all Texas — so the 2064 date is still the operative one.

The database now lists the pair clean — no jeopardy entry, nothing in relief planning — and with Birmingham’s 205/659 carrying a similar forecast into 2066, every corner of Alabama sits on decades of number supply for the first time in a generation.

One code, three southeast Alabama markets

For an outbound operation, this footprint bundles three distinct markets under a single code: the capital’s government-and-services economy, the Auburn–Opelika corridor, and the Wiregrass hub at Dothan. A caller ID from any of them signals hometown to all of them — the mechanics of why that lifts answer rates live in our local presence guide. A 483 number is no less local than a 334; the newer code simply marks a newer line. The flip side: digits carry no guarantee, because caller ID spoofing can forge a Montgomery number from any switch on earth.

SIPNEX approaches that from the carrier side. Holding its own FCC authorization rather than reselling another carrier’s, it stocks local DID numbers by rate center in markets across the US — central Alabama included, subject to inventory — and lands them over SIP trunking on the PBX or dialer your team answers today. Outbound calls go out A-level under a STIR/SHAKEN certificate issued in SIPNEX’s own name, and toll-free numbering runs through its RespOrg registration.

Montgomery, Auburn, or Dothan on the display — either code, same ground. SIPNEX issues the number under its own FCC license, lands it on your systems by SIP trunk, and signs every outbound leg A-level with a STIR/SHAKEN certificate it holds itself.
