Area Codes Serving New Hanover County

New Hanover County is served by the 910/472 overlay complex. Area code 910 is the older and more familiar local code for Wilmington, Carolina Beach, Kure Beach, Wrightsville Beach, Castle Hayne, Ogden, Myrtle Grove, Porters Neck, Monkey Junction, and nearby ZIPs. Area code 472 is not a separate beach-town code or a code for only new Wilmington addresses. It is an all-services distributed overlay on the same geography. A new line in New Hanover County may receive 472 anywhere a 910 line can be assigned.

The NANPA NPA report lists both codes as North Carolina general purpose codes in the same 472/910 overlay complex. The report marks local calls as 10D and toll calls as 1+10D. NANPA also notes that 1+10 digit dialing may be allowed at the service provider's discretion. For local directory work, the practical rule is simple: publish and dial New Hanover County numbers with the full area code.

New Hanover County Area Code Coverage

New Hanover County area code coverage is shared, not divided by town line. The older 910 code and the newer 472 overlay both cover the countywide calling area. A Wilmington business, a Carolina Beach resident, a Wrightsville Beach town office, or a Castle Hayne line can be local to the same overlay complex even when the first three digits after the area code differ. NCUC describes the broader 910 calling area as including Wilmington and New Hanover County along with other southeastern North Carolina places, but the local page focus is the county and its communities.

ZIP clues help with geography, but they do not choose between 910 and 472. Research identified New Hanover County and Wilmington-area ZIPs including 28401, 28403, 28405, 28409, 28411, 28412, 28428, 28429, 28449, and 28480 within the local coverage discussion. These ZIPs line up with Wilmington, Carolina Beach, Kure Beach, Wrightsville Beach, Castle Hayne, and nearby county areas. A number with 472 should not be treated as outside the county simply because many older public numbers still start with 910.

• Wilmington - served by 910 and 472 across the overlay complex.
• Carolina Beach and Kure Beach - served by the same 910/472 geography, with older public numbers often showing 910-458.
• Wrightsville Beach - served by 910 and 472, while town numbers often show a 910-256 pattern.
• Castle Hayne and northern county areas - served by the overlay complex, with CASTLEHAYN appearing as an official rate-center label in NANPA CO-code data.
• Ogden, Porters Neck, Myrtle Grove, and Monkey Junction - treated as part of the shared county coverage area rather than separate area-code zones.

Note: A 472 number can be local to Wilmington or Carolina Beach in the same way a 910 number can.

Overlay and Split Terms

New Hanover County phone history uses both split and overlay concepts. The area code 910 came from a split from 919. In that kind of change, part of an old area receives a new area code while another part keeps the old one. The later 472 change was different. It was an overlay, which put a new code on top of the same geography so existing 910 customers did not have to change numbers.

NPA

The numbering plan area, better known as the area code. For New Hanover County, the active NPAs are 910 and 472.

NXX

The three-digit central-office or prefix code after the area code in an NPA-NXX-XXXX number.

Overlay

A new area code added to the same geographic service area. Existing numbers keep their old code, and new numbers may receive either code.

Split

A change that moves part of an old area-code geography into a new code. Some customers may have to change area codes.

The distinction matters for New Hanover County because 472 did not carve out a beach zone, a north-county zone, or a Wilmington-only zone. It overlays 910. The older 910 code still appears on many county, city, school, and beach-town lines, but newer residential, business, wireless, or VoIP service can use 472 in the same local area.

Dialing Rule for New Hanover County

New Hanover County local calls require 10-digit dialing. That rule was required in the 910 area before the 472 overlay because 988 was an assigned central-office prefix in the NPA. The FCC's 988 transition required affected area codes to move away from seven-digit local dialing so 988 could work as the national Suicide & Crisis Lifeline. The later 472 overlay made 10-digit dialing even more important because the same seven-digit line number could exist under different area codes.

NANPA lists home NPA local calls and foreign NPA local calls as 10D for both 910 and 472. Toll calls are listed as 1+10D, with the service-provider note about optional 1+10 digit dialing. For the rest of the dialing landscape, including N11 codes, star codes, toll-free prefixes, and international access, use the New Hanover County phone codes reference.

New Hanover County Area Code Timeline

The local phone-number story begins with the North American Numbering Plan. NANPA says AT&T developed the NANP in 1947 and implementation began in 1951. New Hanover County was not always a 910 place. NANPA's NPA report identifies 910 as assigned in 1992, in service in 1993, and created with parent NPA 919. That history explains why older regional references may mention 919 even though Wilmington and New Hanover County are now in the 910/472 complex.

Area code 336 later split from 910 for parts of North Carolina outside New Hanover County. That event matters as regional context, not as a local county code change, because New Hanover County stayed with 910. The next local change was the 472 overlay. NCUC approved the all-services distributed overlay in 2021, NANPA listed the assignment shortly after, and the code entered service in 2022. Existing 910 numbers stayed in place.

New Hanover County Exchange Prefixes

The exchange prefix is the NXX, the three digits after the area code in a standard NPA-NXX-XXXX number. In New Hanover County, the NPA can be 910 or 472. The NXX can point to an original central-office or rate-center assignment, but it should not be read as current subscriber proof. Number portability means a phone number can move among wireline, wireless, IP phone, VoIP, and other providers after its original assignment.

The NANPA CO-code utilized report showed three New Hanover-relevant rate-center labels in the inspected 910/472 data: WILMINGTON, CAROLINBCH, and CASTLEHAYN. Kure Beach and Wrightsville Beach are real New Hanover County communities, but they did not appear as separate rate-center labels in the public rows reviewed. That is why an exchange can look local even when its rate-center label does not match the exact town name a caller expects.

Note: NPA-NXX data is allocation evidence, not proof of the current caller, current carrier, or current phone owner.

Future New Hanover County Area Codes

No immediate new area code relief was located for New Hanover County. The research found long-range exhaust projections for the 472/910 complex rather than an active new overlay. NCUC cited a fourth-quarter 2048 exhaust projection in an October 2025 overview, while NANPA 2026-1 listed the 472/910 projected exhaust as 4Q 2050. Those projections place the next relief event decades out, not in the near-term directory cycle.

If relief is needed later, the North Carolina Utilities Commission would have a role in state approval and public notice, as it did for the 472 overlay. The last local overlay did not force existing 910 numbers to change. It added a new pool for new service and extra lines. A future overlay would likely be handled through the same kind of public planning process, with NANPA data and NCUC notices serving as the key official sources.

Verify New Hanover County Area Codes

Area-code verification should start with official numbering sources. The NANPA area-code map resource is the national starting point for geography, while the NANPA NPA report provides code status, overlay complex, assignment date, in-service date, parent code, and dialing fields. For the local 472 rollout, the NCUC 472 overlay release and the NCUC implementation reminder document the state-level approval and the date when assignments could begin.

The FCC ten-digit dialing guide explains the 988 transition that affected area codes where 988 had already been assigned as a prefix. That source is important for New Hanover County because the 910 area code had to use 10-digit dialing before 472 entered service. For a suspicious call, an area code match should only be treated as one clue. Local scam research found sheriff-impostor calls using local-looking numbers, so official agency verification remains the safer route.
