This guide breaks down all of Laurel’s codes across the Washington and Baltimore numbering plans, the required 10-digit dialing, major ZIP codes, and local scam warnings.

Area Code Breakdown & Regional Mapping
301 – Washington Side (301 core)
Area code 301 (the Washington-suburbs code) and its overlay serve the Prince George’s County portion of Laurel — the historic core of the city on the Washington side of the corridor.
240 – Washington Side Overlay
Area code 240 is the overlay for 301, sharing the same Washington-suburbs geography. Laurel lines on the Prince George’s side may carry a 240 number, fully local to 301.
410 – Baltimore Side (410 core)
Area code 410 (the Baltimore-region code) serves the parts of the Laurel area that fall in Anne Arundel and Howard counties, on the Baltimore side of the corridor, such as North and West Laurel.
443 – Baltimore Side Overlay
Area code 443 is the first overlay for the 410 region and appears on many numbers in the Anne Arundel and Howard portions of the Laurel area.
667 – Baltimore Side Overlay (newest)
Area code 667 is the newest overlay for the 410/443 region, also appearing on the Baltimore-side portions of the Laurel area.
Neighborhoods & Local Coverage
Laurel’s codes reflect its position on the county lines. The historic Old Town Laurel, centered on Main Street and the Patuxent River mills, sits in Prince George’s County and uses the Washington-side 301/240 codes. This walkable historic district is the heart of the city and home to its 19th-century railroad heritage.
North of Old Town, the North Laurel and Maple Lawn areas fall in Howard County, while the South Laurel and Russett communities extend into Anne Arundel County — both on the Baltimore-side 410/443/667 codes. Because Laurel sits at the junction of the two numbering regions and three counties, residents may have either a 301-family or a 410-family number depending on exactly where they live. Laurel Park racetrack anchors the city’s southern edge.
Local Dialing Rules & International Format
Laurel requires 10-digit dialing throughout, since both the Washington complex (301/240) and the Baltimore complex (410/443/667) are overlaid. Always dial the area code plus the 7-digit number, and note that a Laurel number could belong to either code family depending on the neighborhood.
Laurel is in the Eastern Time Zone (EST/EDT), like all of Maryland. To call the city from outside the United States, dial your country’s exit code, then the U.S. country code +1, followed by the 10-digit number (for example, +1 301 XXX-XXXX). From inside the U.S. and Canada, simply dial 1 before the 10-digit number for long-distance calls.
Major ZIP Codes Covered
The Laurel area spans several ZIP codes across three counties, including 20707, 20708, 20723 (North Laurel, Howard County), and 20724 (South Laurel, Anne Arundel County).
Spam & Scam Call Warnings in Laurel
Laurel residents report neighbor-spoofing robocalls faking both local 301 and 410 prefixes, plus fake utility-shutoff threats from callers posing as BGE and Pepco. Because Laurel spans two area-code families, scammers may spoof either to appear local.
| Scam Type | What to Watch For |
|---|---|
| Neighbor Spoofing | Calls that mimic a local 301 prefix to look familiar. |
| Utility / Toll Scams | Threats to shut off power or demand toll payment via gift cards. |
| IRS / Government | Robocalls claiming legal action — agencies never call to demand instant payment. |
Red flag: Any caller who pressures you to pay immediately with gift cards, wire transfers, or cryptocurrency is almost certainly running a scam. Hang up and verify through an official number.
