Area Codes by Time Zone: Every U.S. Area Code, Including Codes Split Across Two Zones

Looking up area codes by time zone? An area code is in the time zone of the place it covers. Most U.S. area codes sit entirely in one zone: Manhattan’s 212 is Eastern, Chicago’s 312 is Central and Los Angeles’s 310 is Pacific. A few, such as 850 in the Florida Panhandle and 208 in Idaho, cross into two zones.

Below are all 378 geographic area codes in service in the 50 states, Washington, D.C. and the U.S. territories, sorted by time zone. The list matches the area code database of NANPA, the organization that assigns area codes, as of October 19, 2026. Overlay codes are included; an overlay covers the same area as an older code, so it shares its time zone.

Canada and the Caribbean countries that share the +1 country code are left out, and so are toll-free and other codes not tied to a place, such as 800, 888, 500 and 900.

How to Find Area Codes by Time Zone in These Tables

1. Search for the code. Press Ctrl+F (Command+F on a Mac) or use Find on Page on your phone, and type the three digits. Each table is sorted by state, then by number.
2. Read the Main area column. If part of the area is on another zone, it says so. Those codes are also listed in their own section further down.
3. Check daylight saving time. Arizona, Hawaii and the territories don’t change their clocks.

One caution: an area code shows where a number was first assigned, not where the person is now. People keep their numbers when they move, and the code doesn’t show the type of phone either (see is 646 a cell phone or a landline).

What Time Is It There? A Quick Comparison With New York

Here’s what the clock says in each zone when it’s 12:00 noon in New York (212). Zones that use daylight saving time change on the same days, so their gap with New York stays the same all year.

Time zone	Example area codes	When it’s noon in New York
Eastern	212, 305, 404, 617	12:00 noon
Central	312, 214, 615, 504	11:00 a.m.
Mountain	303, 801, 505, 406	10:00 a.m.
Arizona (Mountain, no daylight saving)	602, 480, 520, 928	10:00 a.m. in winter, 9:00 a.m. in summer
Pacific	310, 415, 206, 702	9:00 a.m.
Alaska	907	8:00 a.m.
Hawaii-Aleutian	808	7:00 a.m. in winter, 6:00 a.m. in summer
Atlantic	787, 939, 340	1:00 p.m. in winter, 12:00 noon in summer
Chamorro	671, 670	3:00 a.m. the next day in winter, 2:00 a.m. the next day in summer
Samoa	684	6:00 a.m. in winter, 5:00 a.m. in summer

Eastern Time Zone Area Codes

The Eastern zone has the most area codes, 174, covering the East Coast, Ohio, Michigan and most of Florida and Indiana. All of New York City is here. The newest code, 465 for the four boroughs outside Manhattan, switched on June 18, 2026, but its numbers aren’t expected to be handed out until around the third quarter of 2027.

Area Codes That Cross Two Time Zones

These 23 area codes cover places on both sides of a time zone line. We checked each one against NANPA’s database and the official zone boundaries in federal rules, 49 CFR Part 71. In the tables above, each code is listed under the zone where most of its people live, with a note about the other part.

Area code	State	Mostly on	Part on another zone
850, 448	Florida	Central (Pensacola, Panama City)	Eastern: Tallahassee and the area east of the Apalachicola River
219	Indiana	Central (Gary, Hammond)	Eastern: Monon and Wolcott in White County
574	Indiana	Eastern (South Bend, Elkhart)	Central: Starke County (Knox, North Judson)
812, 930	Indiana	Eastern (Bloomington, Columbus)	Central: the Evansville area in the far southwest
270, 364	Kentucky	Central (Bowling Green, Paducah)	Eastern: Hardin and Meade counties (Elizabethtown, Radcliff) and nearby
606	Kentucky	Eastern (Ashland, Pikeville)	Central: Clinton County (Albany)
906	Michigan	Eastern (Marquette, Sault Ste. Marie)	Central: Gogebic, Iron, Dickinson and Menominee counties
423, 729	Tennessee	Eastern (Chattanooga, Johnson City)	Central: Bledsoe, Sequatchie and Marion counties
308	Nebraska	Central (Grand Island, Kearney)	Mountain: the Panhandle (Scottsbluff, Alliance, Sidney)
605	South Dakota	Central (Sioux Falls)	Mountain: western South Dakota (Rapid City)
701	North Dakota	Central (Fargo, Bismarck)	Mountain: the southwest (Dickinson)
620	Kansas	Central (Hutchinson, Dodge City)	Mountain: Greeley and Hamilton counties
785	Kansas	Central (Topeka, Salina)	Mountain: Sherman and Wallace counties
208, 986	Idaho	Mountain (Boise, Idaho Falls)	Pacific: north of the Salmon River (Coeur d’Alene, Lewiston)
541, 458	Oregon	Pacific (Eugene, Bend)	Mountain: most of Malheur County (Ontario)
775	Nevada	Pacific (Reno, Carson City)	Mountain: the city of West Wendover
907	Alaska	Alaska	Hawaii-Aleutian: the far western Aleutian Islands (Adak)

Texas is also split by a zone line, but there each area code stays on one side: every Texas code is on Central time except 915 (El Paso), which is on Mountain time.

Daylight Saving Time: Which Area Codes Don’t Change Their Clocks

Most of the country moves its clocks forward one hour on the second Sunday in March and back on the first Sunday in November. According to the U.S. Department of Transportation, which oversees time zones, these places don’t observe daylight saving time:

• Most of Arizona: 480, 520, 602, 623 and 928
• Hawaii: 808
• Puerto Rico: 787 and 939
• U.S. Virgin Islands: 340
• Guam: 671
• Northern Mariana Islands: 670
• American Samoa: 684

The big exception is the Navajo Nation in northeastern Arizona, inside the 928 area code. It does observe daylight saving time. So in summer, a 928 number in Window Rock is one hour ahead of a 928 number in Flagstaff.

The rest of Arizona shares Los Angeles’s clock in summer and Denver’s in winter. Hawaii is five hours behind New York in winter and six in summer.

Frequently Asked Questions

What time zone is the 212 area code in?
Eastern. 212 covers Manhattan in New York City, and so do its overlays 646 and 332, plus 917, which covers all five boroughs. For more on Manhattan’s original code, see our brief history of area code 212.

What time zone are 310, 415 and 305?
310 (West Los Angeles and the South Bay) and 415 (San Francisco and Marin County) are on Pacific time. 305 (Miami-Dade County and the Florida Keys) is on Eastern time, three hours ahead of 310 and 415.

Which area codes are in two time zones?
We confirmed 23, in Florida, Indiana, Kentucky, Michigan, Tennessee, Nebraska, the Dakotas, Kansas, Idaho, Oregon, Nevada and Alaska. The best known are 850 in the Florida Panhandle and 208 in Idaho. The full list is in the two-zone table above.

Does an area code tell me what time it is for the person I’m calling?
Not always. It tells you where the number was first assigned. Someone with a 212 number may live in California today, so if the time matters, ask.

Is Arizona on Mountain or Pacific time?
Mountain. Arizona stays on Mountain Standard Time all year, so it matches Pacific time in summer. The Navajo Nation, in the 928 area code, does change its clocks.

How many area codes does the U.S. have?
NANPA lists 378 geographic area codes in service in the U.S. and its territories as of October 19, 2026, all in the tables above. Three more are planned but not yet in service: 565 in southeast Georgia (due December 6, 2027), 761 around Louisville, Kentucky, and 451 in western North Carolina. See how many area codes are in the US.

Are Canadian area codes on this list?
No. Canada and many Caribbean countries use the same +1 system, but this list covers only the U.S. and its territories.
