The 227 area code is Maryland's newest — activated in June 2023 as the second overlay on the state's 301/240 region, from the DC suburbs of Montgomery and Prince George's counties out to Frederick, Hagerstown, and the western Maryland mountains. It has nothing to do with Niger's +227 country code, despite the search overlap. This guide covers where 227 reaches, its place in the 301/240/227 overlay stack, dialing, and how to get a 227 business number on a full UCaaS platform.
Of every area code in this series, 227 is the youngest. It went into service in Maryland in June 2023 — one of the newest area codes in the entire United States — as a second overlay on the state's already-crowded 301/240 region. For a business, that means a 227 business number is about as fresh as inventory gets: no decades of history, just brand-new numbers in a well-established part of Maryland.
Whether you just missed a call from this code, you are researching where is 227 area code before opening a Maryland location, or you are ready to set up a 227 UCaaS business number that turns inbound calls into customers, this guide covers the coverage area, how 227 fits alongside 301 and 240, the Niger country-code mix-up, dialing rules, and exactly how to get a 227 number backed by a complete unified-communications platform.
| Detail | Value |
|---|---|
| State | Maryland |
| Region | Western Maryland — DC suburbs to the mountains |
| Major areas | Montgomery County, Prince George's County, Frederick, Hagerstown, Cumberland |
| Parent codes | 301 (original, 1947) and 240 (first overlay, 1997) |
| In service since | June 14, 2023 — the second overlay on the 301/240 territory |
| Overlay relationship | 301, 240, and 227 all share the exact same footprint |
| Time zone | Eastern Time (ET) |
| Country | United States (227 area code USA) |
The "in service since June 2023" row says it all: 227 is one of the newest area codes in the country, not just in this series. For a business, a brand-new 227 UCaaS business number means clean, largely unallocated inventory in a market that has been dialed for over 75 years under 301.
The 227 area code covers the same broad swath of western Maryland that 301 and 240 already serve: the Washington, DC suburbs of Montgomery County and Prince George's County, then out through Frederick, Hagerstown, and Cumberland toward the Appalachian foothills. It is one of the most densely populated overlay territories in this series, anchored by its proximity to the nation's capital. Montgomery County is home to the National Institutes of Health's Bethesda campus, one of the region's largest employers, while Frederick anchors Fort Detrick, a major US Army biomedical research installation — real institutional weight behind a 227 number, not just proximity to DC.
One clarification worth stating plainly: 227 area code in Africa refers to something else entirely — +227 is Niger's international country calling code, a completely separate numbering system. As a US area code, 227 area code usa is the correct context, and it has only ever served Maryland.
301 was assigned to Maryland in 1947, one of the original North American area codes, and for exactly fifty years it was the only code the region needed. As the DC suburbs grew through the 1990s, 240 was added in 1997 as the first overlay, sharing the identical 301 footprint rather than splitting it. That pattern held for another 26 years, until cell phones and second lines pushed the combined 301/240 pool toward exhaustion again — and in 2023, 227 arrived as the second overlay on the same unchanged territory.
Because all three codes stack on one footprint rather than dividing it, every business that had a 301 or 240 number in 1997 or earlier kept it unchanged — 227 simply gives the region a third option for new lines, and 10-digit dialing has applied across the whole territory since 2001.
| Code | Added | Layer |
|---|---|---|
| 301 | 1947 (original) | Base layer — Maryland's founding code for this region |
| 240 | 1997 overlay | First overlay on the same 301 territory |
| 227 | 2023 overlay | Second overlay, layered on the same territory again |

The 227 area code time zone is Eastern Time — EST (UTC−5) in winter and EDT (UTC−4) during daylight saving, the same clock as Washington, DC, Baltimore, and the rest of Maryland.
Because three codes now share this one territory, seven-digit dialing has not worked here in over two decades — every local call, even between two Montgomery County numbers, needs the full 10 digits.
A local 227 phone number puts a business inside one of the freshest number pools in the country while still reading as a genuine DC-suburbs-to-western-Maryland presence. On a modern UCaaS (Unified Communications as a Service) platform, that number ships as a complete business phone system, not a bare line, so every inbound call has a real chance of converting.

Because +227 is also Niger's international country calling code, searches for 227 area code country and 227 area code in africa turn up genuinely mixed results online. The two numbering systems are unrelated: Niger's +227 is dialed internationally as part of the global country-code system, while Maryland's 227 is a domestic US area code inside the North American Numbering Plan, dialed as 1-227-XXX-XXXX from anywhere else in the US or Canada.
If a call or text shows a "227" prefix, the surrounding digits tell you which system you are looking at: a US 227 number is always exactly 10 digits domestically (227 + 7 more), while a Niger call arriving internationally will show a leading + or 011 country-code prefix ahead of it. For a Maryland business, that distinction is worth knowing if customers ever ask about it — a genuinely new area code sharing digits with a country code is an unusual coincidence, and getting ahead of the confusion is easy once you know the difference.
The 227 area code is Maryland's newest — a June 2023 overlay stacked on top of the 301 and 240 codes that have served the DC suburbs and western Maryland since 1947 and 1997. It shares its digits, coincidentally, with Niger's international country code, but the two have never had anything to do with each other.
For any business serving Montgomery County, Frederick, Hagerstown, or the wider 227 territory, a 227 business number on a full UCaaS platform is fresh, recognizable inventory backed by enterprise phone features and lead-ready call handling, with no physical Maryland office required.
The 227 area code covers western Maryland — the DC suburbs of Montgomery and Prince George's counties, plus Frederick, Hagerstown, and Cumberland. It operates on Eastern Time. It is not related to Niger's +227 country code, which is a separate international numbering system.
Both exist, unrelated. Maryland's 227 is a domestic US area code activated in June 2023, part of the North American Numbering Plan. Niger's +227 is an international country calling code. A US 227 number is dialed as 227-XXX-XXXX domestically; a Niger number is dialed with a + or 011 international prefix.
There is no geographic difference — all three are overlay codes covering the exact same western Maryland territory. 301 is the original from 1947, 240 was added in 1997 as the first overlay, and 227 was added in June 2023 as the second overlay. Every local call requires 10-digit dialing as a result.
The 227 area code operates in the Eastern Time Zone — EST (UTC−5) in winter and EDT (UTC−4) during daylight saving, the same clock as Washington, DC and Baltimore.
The 227 area code went into service on June 14, 2023, making it one of the newest area codes in the United States. Numbers have been actively assigned in it since 2025.
