704 Area Code: Charlotte, NC and the 980 Overlay

The essentials

704 area code: quick facts

How 704 became Charlotte's code

NANPA says AT&T developed the North American Numbering Plan in 1947 to simplify direct dialing of long-distance calls, and that implementation of the plan began in 1951. The dates below come from the FCC, from NANPA planning letters, and from the NCUC orders those letters describe.

1. January 1947: Area code 704 opens, according to the FCC's table of area code opening dates. NANPA gives January 1, 1947 as its in-service date. It was North Carolina's only area code until 919 opened in 1954.
2. January 1954: Area code 919 opens (FCC). NANPA gives January 1, 1954 as the in-service date.
3. March 22, 1998: Area code 828 opens, taken from 704 (NANPA; FCC lists March 1998). The NCUC's September 2026 release describes 828 as the code that serves western North Carolina.
4. October 17, 1999: NANPA Planning Letter PL-204 says the NCUC approved an all-services overlay of the 704 area in Docket No. P-100, Sub 137a, and that NANPA assigned 980. That first plan put 980 in service on December 1, 2000, with mandatory 10-digit dialing from November 1, 2000.
5. April 25, 2000: The NCUC issues an order moving mandatory 10-digit dialing to January 10, 2001, and the effective date of 980 to February 10, 2001 (NANPA PL-229, dated April 28, 2000, which replaced PL-204).
6. May 1, 2000: Permissive 10-digit dialing begins. During this period, callers in the 704 area could dial local calls with either 7 or 10 digits (PL-229).
7. January 5 and January 17, 2001: Two further NCUC orders delay mandatory 10-digit dialing, first to January 24, 2001 and then to March 15, 2001 (NANPA PL-258, dated January 23, 2001).
8. March 15, 2001: Mandatory 10-digit dialing for local calls begins (PL-258).
9. April 1, 2001: A clarifying NCUC order sets this date for activating codes in the new 980 area code (PL-258). The FCC lists 980 as opened in April 2001.

Where area code 704 is used

Because 980 is an overlay, the regulator treats 704 and 980 as one area. The Public Staff of the NCUC publishes a map titled "704/980 Area Code", dated October 2014, that shows telephone exchange boundaries and county boundaries. The counties named on that map are Mecklenburg, Cabarrus, Gaston, Union, Iredell, Rowan, Stanly, Anson, Lincoln, Cleveland, and Catawba. The map draws exchange lines, not county lines, so it does not say that every one of those counties is wholly inside 704/980.

The exchanges labeled on the 2014 map, and the rate centers listed on NANPA's map attached to the April 2000 planning letter, include Charlotte, Gastonia, Concord, Kannapolis, Salisbury, Statesville, Mooresville, Monroe, Shelby, Albemarle, Huntersville, Matthews, Lincolnton, Belmont, Davidson, Kings Mountain, Wadesboro, and Waxhaw. A rate center is a billing area, not a boundary. The sources checked do not give an official list of every city where 704 numbers are found today, so confirm a specific address with your phone provider.

Why 704 added 980

The NANPA planning letters call 980 an "all-services overlay" of the 704 area. Under an overlay, existing numbers keep their area code, and new numbers can be assigned from either code in the same territory. NANPA's April 2000 letter said codes in 980 could be assigned to service providers after August 10, 2000, but could not be activated before the effective date.

The rollout did not run on its first schedule. NANPA's October 1999 letter put 980 in service on December 1, 2000. An April 2000 NCUC order moved that to February 10, 2001, and two orders in January 2001 pushed mandatory 10-digit dialing back to March 15, 2001. A clarifying order then set April 1, 2001 as the activation date for 980 codes, and for the formerly protected codes in 704.

Area code planning in North Carolina follows the same pattern today. In its September 2026 release on the 828 area, the NCUC says it has previously approved similar overlay relief in the Charlotte, Raleigh, Greensboro, and Wilmington areas. The same release says industry guidelines call for an overlay to be in place at least six months before an area code runs out.

NANPA's April 2026 analysis projects that the 704/980 area will run out of numbers in the third quarter of 2038, based on data as of March 1, 2026. The previous forecast in that report was the first quarter of 2036, so the estimate moved out by ten quarters. NANPA's July 6, 2026 list of revised exhaust dates does not include 704/980. Forecasts move from one analysis to the next, so treat the date as an estimate.

The recent reports show how much the estimate moves. NANPA's April 2025 analysis put the 704/980 exhaust in the first quarter of 2035, its next forecast moved it to the first quarter of 2036, and the April 2026 analysis moved it again to the third quarter of 2038. Each report is based on number use and code assignments reported by carriers, so a slower pace of code assignments pushes the date later. None of the sources checked mention a third code for the Charlotte area.

Area codes connected to 704

The table shows codes tied to 704's history or named in the North Carolina and NANPA sources in this guide. The sources checked do not give an official list of which codes border 704/980, so the table does not claim that each one is a direct neighbor.

The Public Staff says North Carolina is divided into six geographic numbering plan areas and publishes a map for each: 252, 336/743, 704/980, 828, 910, and 919/984.

The overlay code that shares 704's territory

An overlay adds a new area code to the same geographic area, so existing numbers do not change. One overlay code serves the Charlotte area alongside 704:

• 980 (approved in Docket No. P-100, Sub 137a; announced by NANPA on October 17, 1999; codes active from April 1, 2001): North Carolina's overlay for the 704 area.

Because the codes overlap, two neighbors on the same street can have different area codes. NANPA's planning letters say 980 shares the same dialing plan as 704, so a local call to a 980 number is dialed the same way as a local call to a 704 number.

Time zone and daylight saving time

Area code 704 uses Eastern Time. The tz database lists America/New_York as "Eastern (most areas)". Under federal rules, the eastern zone covers the part of the United States east of the boundary line described in 49 CFR 71.5 (49 CFR 71.4). In the South, that line runs through Tennessee, along the west lines of counties such as Scott, Morgan, Rhea, and Hamilton, so it lies well west of North Carolina and the Charlotte area.

NIST says daylight saving time begins at 2:00 a.m. on the second Sunday of March and ends at 2:00 a.m. on the first Sunday of November. The NIST page lists Hawaii, American Samoa, Guam, Puerto Rico, the Virgin Islands, and Arizona as places that do not observe it, and North Carolina is not on that list. In 2026, NIST gives March 8 and November 1 as the change dates.

How to dial a 704 number

North American numbers have three parts: a country code, a three-digit area code, and a seven-digit local number. NANPA says the ITU assigned country code 1 to the NANP area. NANPA's planning letters for the 980 overlay give the dialing plan for the 704 area:

• All local calls are dialed as 10 digits: area code plus the seven-digit number.
• All toll calls are dialed as 1 plus 10 digits.
• Operator-assisted, third-party, and credit calls are dialed as 0 plus 10 digits.

Mandatory 10-digit dialing for local calls began on March 15, 2001 (PL-258). Before that, a permissive period starting May 1, 2000 let callers use either 7 or 10 digits.

The reason is the overlay itself. Once 704 and 980 serve the same territory, the same seven digits can belong to two different numbers, one in each code, so the area code is needed to tell them apart. That is why the planning letters set mandatory 10-digit dialing before the first 980 codes could be activated. If you call a Charlotte-area number from elsewhere in the United States, dial 1 plus the 10-digit number. From outside the NANP area, dial your international access code, then 1 and the 10 digits.

Caller ID and scams with a 704 number

The FTC warns that "Scammers can make any name or number show up on your caller ID." That is called spoofing. Scammers can also match the first six digits of your own number, which the FTC calls neighbor spoofing.

• If you pick up and do not recognize the caller, the FTC advises that you hang up.
• Letting an unknown call go to voicemail is one option.
• The FTC says call blocking is your best defense against unwanted calls.

The sources checked do not say that 704 numbers are targeted more than others. A 704 number shows the code that was assigned, not who is calling or where they are. Because 980 shares the same territory, and because a number can be spoofed, a 704 caller ID is not a reliable sign that the caller is in Charlotte.

Choosing a 704 number for a business

704 is the older of the two Charlotte-area codes, but it is not the only one. With an all-services overlay, a new line in the area may carry 980 instead of 704, and the area code does not show which part of the region the business is in.

Because the codes share territory, route calls by team or extension, not by area code. Ask your provider which code a new line gets, since that depends on its current inventory.

Whether a specific 704 number can be assigned to your business depends on your phone provider and its current inventory. This guide does not make claims about availability.

Important: Confirm availability with your provider before you plan a campaign or print a number on materials.

Before you use a 704 number

• Confirm the number is available from your provider, and get its terms in writing.
• Ask who owns the number and whether it can be moved to another provider if you switch.
• Confirm which area code your line uses. 704 and 980 serve the same territory.
• Set 10-digit dialing for numbers in both codes before you go live, because local calls in the 704 area have required 10 digits since March 15, 2001.
• Update stored numbers on equipment that dials out or forwards calls, and print the full 10-digit number with the area code.
• Route calls by team or extension, because 704 and 980 share one territory.
• Plan for caller ID. A 704 number does not prove who is calling, and neighbor spoofing copies the first six digits of your own number.
