Area Code for El Paso, TX
El Paso uses one area code: 915 (est. 1947). History, neighborhoods, Mountain Time zone, border identity, scam alerts, and how to get a 915 business number.
El Paso, Texas runs on a single area code: 915 — one of the original NANP codes assigned in October 1947 and still the only code for the far west Texas metro nearly 80 years later.
No overlay. No split planned. Just 915, spanning El Paso County and the surrounding border region where Texas meets New Mexico, Arizona, and Mexico’s state of Chihuahua.
What’s the area code for El Paso?
El Paso and the far west Texas region are served by a single area code under the North American Numbering Plan (NANP):
| Code | Established | Coverage | Notes |
|---|---|---|---|
| 915 | October 1947 | El Paso, Culberson, and Hudspeth counties | Original NANP code; no overlay as of 2026 |
915 covers three counties: El Paso (the city and metro), Culberson (Van Horn), and Hudspeth (Sierra Blanca, Fort Hancock).
El Paso is in the Mountain Time Zone (MT) — UTC−7 winter, UTC−6 during DST. It is the only major Texas city not on Central Time.
Ten-digit dialing has been required since 2021. The change was administrative — not a new code addition. It arose because 988 was designated the National Suicide and Crisis Lifeline, conflicting with a central office code 988 already in use within the 915 region.
Neighboring codes: 575 (southern New Mexico / Las Cruces / Sunland Park), 432 (Midland / Odessa / Permian Basin), 520 (southern Arizona). Ciudad Juárez, Mexico uses country code +52 with area code 656.
El Paso metro area codes by region
915 is the single code for the entire El Paso metro. Every neighborhood, suburb, and adjacent community on the Texas side uses 915 — no code boundaries exist within the metro.
Downtown El Paso
The central business district along Montana Avenue and Mesa Street carries legacy 915 numbers for city government, law firms, banks, and regional corporate offices.
West Side and Upper Valley
El Paso’s affluent West Side neighborhoods — near the Franklin Mountains State Park — extend toward Sunland Park, New Mexico (across the state line, uses 575). The UTEP campus on the West Side is fully within 915 territory.
East Side and Northeast
The East Side includes large residential corridors along I-10 east of downtown. Horizon City — a fast-growing suburb in Hudspeth County — is within 915 coverage.
Lower Valley and Mission Valley
The Lower Valley stretches southeast along the Rio Grande toward Fabens and Tornillo. Communities including Socorro, San Elizario, and Clint are within 915. Mission Valley runs along the river corridor south of downtown.
Canutillo and Anthony
Canutillo (northwest of downtown, near New Mexico border) uses 915. Anthony straddles the Texas–New Mexico state line — the Texas side uses 915; the New Mexico side of Anthony uses 575.
Sunland Park, NM (575 — across state line)
Sunland Park is physically connected to El Paso’s West Side but is in New Mexico, making it 575 territory. Businesses operating across the El Paso–Sunland Park border should note the code switch at the state line.
History of El Paso area codes
El Paso’s area code history is one of stability punctuated by a single major split — a contrast to the constant code proliferation in Dallas or Houston.
October 1947 — 915 assigned. When AT&T engineers designed the NANP, they assigned 915 to cover northwestern Texas. The original territory stretched from El Paso east across the Permian Basin, north into the Panhandle area, and toward Fort Worth. It was one of the largest NPA territories in the US by geography.
1954 — 817 splits off eastern territory. Nearly the entire eastern portion — including Fort Worth and the South Plains — became area code 817. 915 retained El Paso and the west Texas corridor.
1957 — 806 splits off the Panhandle. The Texas Panhandle (Amarillo and surrounding territory) was carved out as area code 806. 915 was reduced to far west Texas: El Paso, the Permian Basin, and the Trans-Pecos region.
November 8, 2003 — 432 splits off the Permian Basin. Population growth and the explosion of mobile phones in the oil patch drove number exhaustion in the Midland/Odessa/Permian Basin region. The PUCT authorized area code 432, which took over the eastern portion of 915 territory. El Paso retained 915; Midland and Odessa became 432.
2021 — Ten-digit dialing required. When 988 was designated the National Suicide and Crisis Lifeline access code, a conflict arose with existing central office code 988 within the 915 region. All El Paso-area calls were converted to mandatory ten-digit dialing. This was a procedural change — not a new code.
2026 — No overlay pending. NANPA has filed no petition for an El Paso overlay or split. 915 remains the sole code for the region.

915 as El Paso and border identity
Few US area codes carry the cultural and geographic weight that 915 does in El Paso. The number is shorthand for a specific place — and a specific way of life at the western edge of Texas.
Franklin Mountains. The Franklin Mountains State Park sits entirely within El Paso’s city limits — the largest urban park in the United States. The mountains divide the East Side from the West Side, and 915 is the code on both slopes.
Fort Bliss. Fort Bliss is one of the largest US Army installations by land area, spanning El Paso and extending into New Mexico. Its economic impact anchors El Paso’s defense sector; thousands of military and civilian employees carry 915 numbers.
UTEP. The University of Texas at El Paso enrolls over 24,000 students. It is the only major US research university with a majority Mexican-American student body. UTEP’s distinctive Bhutanese architectural style — inspired by the Paro Dzong monastery — is as iconic to El Paso as the Franklin Mountains.
Hispanic-majority demographics. El Paso is approximately 80% Hispanic or Latino, one of the highest concentrations of any large US city. The city is functionally bilingual — Spanish and English are spoken interchangeably across business, government, and daily life.
US–Mexico border economy. El Paso–Ciudad Juárez is one of the largest binational metro areas in North America, with a combined population exceeding 2.5 million. The USMCA (formerly NAFTA) cross-border trade corridor passes through El Paso, making it a hub for maquiladora manufacturing, logistics, and cross-border commerce. The Ysleta–Zaragoza and Bridge of the Americas crossings handle billions in annual trade.
Sun Bowl. The Tony the Tiger Sun Bowl (UTEP’s stadium) hosts one of the oldest college football bowl games in the United States. “915” is worn as identity by El Paso locals the way “713” is worn in Houston or “212” in New York.
El Paso area code spam and scams
The 915 area code is regularly spoofed by scammers targeting El Paso residents with fraud patterns specifically designed for the border community.
DEA and federal agency impersonation. Callers claim to be DEA, SSA, or FBI agents, asserting the victim’s Social Security number was used in drug trafficking linked to cartel activity. They use fake badge numbers and case file details, and demand payment via gift cards (Target, Home Depot) or wire transfer.
Border-specific immigration fraud. Scammers exploit El Paso’s border status with calls claiming immigration violations or impending deportation — targeting both English and Spanish speakers. These calls are designed to trigger fear around immigration status and extract wire transfers or personal information.
El Paso Electric impersonation. Callers spoof El Paso Electric’s customer service number and threaten immediate power disconnection unless payment is made within hours by prepaid debit card or cryptocurrency. El Paso Electric has issued repeated public warnings: the company never requests gift card or crypto payments over the phone.
Bilingual fraud (EN/ES). Scammers targeting the 915 area code frequently operate in both English and Spanish, switching between languages to build false credibility with bilingual El Paso residents.
Jury duty and warrant calls. Spoofed calls claiming the recipient missed jury duty or has an outstanding warrant, with instructions to call back on a fake “sheriff’s office” number to arrange payment.
STIR/SHAKEN call authentication. The FCC-mandated STIR/SHAKEN framework requires carriers to authenticate outbound calls and assign an attestation level: A (fully verified), B (partial), or C (gateway/unverified). Spoofed scam calls receive C-attestation or none — triggering “Spam Likely” labels on iOS and Android.
When you get an El Paso number through DialPhone, outbound calls carry A-attestation — verified at the highest trust level so your legitimate 915 calls reach contacts as verified, not screened.

El Paso area code FAQ
El Paso area code FAQ
What is the area code for El Paso, Texas?
The area code for El Paso is 915. It is the only area code serving El Paso and the surrounding far west Texas region — there is no overlay, no split, and no second code active as of 2026.
915 is one of the original North American Numbering Plan (NANP) codes, assigned in October 1947. It covers El Paso County plus Culberson and Hudspeth counties to the east. Ten-digit dialing became required in 2021 due to a conflict with the 988 Suicide and Crisis Lifeline designation.
Does El Paso have more than one area code?
No. El Paso has exactly one area code: 915. Unlike Dallas (four codes) or Houston (five codes), El Paso operates under a single code with no overlay and no planned split as of 2026.
NANPA has not filed any petition for a new El Paso overlay or split. The last major change was a 2021 administrative update requiring ten-digit dialing — not a new code addition. El Paso's population size (~677,000 city proper) means number exhaustion pressure is lower than in Texas's major metros.
What time zone is El Paso?
El Paso is in the Mountain Time Zone (MT) — UTC−7 in winter (Mountain Standard Time) and UTC−6 during Daylight Saving Time. This makes El Paso unique: it is the only major Texas city not on Central Time.
El Paso operates on the same clock as Denver, Phoenix, and Albuquerque — not Houston or Dallas. Business hours in El Paso are 9 AM–5 PM MT. Callers from New York (ET) are 2 hours ahead; callers from Los Angeles (PT) are 1 hour behind.
What area codes border El Paso?
El Paso sits at the intersection of three states and one country, making its neighboring codes unusually diverse.
575 covers southern New Mexico including Las Cruces and Sunland Park — communities physically adjacent to El Paso's West Side. 432 covers Midland, Odessa, and the Permian Basin to the east — it split from 915 in 2003. 520 covers southern Arizona including Tucson and Douglas. Ciudad Juárez, Mexico (directly across the Rio Grande) uses Mexican country code +52 and Mexican area code 656.
Is 915 a scam area code?
915 is a legitimate El Paso area code — not inherently a scam code. However, scammers spoof 915 numbers to exploit local trust, particularly targeting El Paso's border community with immigration-themed fraud.
Common patterns: DEA or SSA impersonation claiming drug trafficking investigation (asks for gift cards), fake jury duty warrant calls, El Paso Electric utility shutoff impersonation, and bilingual EN/ES fraud targeting the city's 80%+ Hispanic-majority population. If a caller demands gift cards, crypto, or wire transfers, hang up regardless of caller ID.
Can I get an El Paso 915 number without an El Paso office?
Yes. Virtual VoIP numbers are not tied to a physical address. Any US or international business can get a 915 number through a cloud phone provider and route calls to any device.
DialPhone assigns available El Paso 915 numbers in minutes. No Texas office, no hardware, no long-term contract required. Outbound calls display your El Paso caller ID, and DialPhone's STIR/SHAKEN A-attestation ensures calls reach contacts as verified — not labeled 'Spam Likely.'
When did El Paso area code 432 split from 915?
Area code 432 split from 915 on November 8, 2003. The split separated the Permian Basin territory — Midland, Odessa, and surrounding oil country — from El Paso's far west Texas region.
Before the split, a single 915 code covered a vast territory from El Paso east through the Permian Basin. The growth of mobile phones and pagers in the oil patch drove number exhaustion, prompting the Public Utility Commission of Texas (PUCT) to authorize 432. El Paso retained 915; Midland and Odessa moved to 432.
What major companies and institutions use 915?
915 is the home code for El Paso Electric (regional utility), Helen of Troy (consumer products company, NYSE: HELE), Hunt Companies (real estate and infrastructure), Western Refining (now Marathon Petroleum subsidiary), Fort Bliss (largest US Army installation by land area), UTEP (University of Texas at El Paso), and MountainStar Healthcare (regional hospital network).
The 915 code also covers the El Paso border crossing infrastructure — one of the busiest US-Mexico land ports for commercial trade under USMCA (formerly NAFTA).
