What Is the 651 Area Code?

The 651 area code is a North American Numbering Plan (NANP) code covering Saint Paul and the eastern Twin Cities metropolitan area in Minnesota. It spans Ramsey County — home to the state capital — along with portions of Dakota and Washington Counties, serving a corridor from the western edge of Saint Paul east to the St. Croix River border with Wisconsin. The zone has no overlay: it is the only dialing code for this part of the Twin Cities metro.

What Does the 651 Zone Cover?

The 651 territory covers an arc of communities east of Minneapolis, anchored by Saint Paul in the center. To the north lie White Bear Lake and North St. Paul; to the east, Stillwater and the St. Croix River valley; to the south, Eagan, Inver Grove Heights, and South St. Paul; and at the core, the dense urban neighborhoods of Saint Paul itself. The zone is bounded to the west by the Minneapolis metro, where the 612 area code takes over across the Mississippi River.

651 Area Code History: Split from 612

Minnesota's original 1947 NANP code, 612, once covered the entire Twin Cities metropolitan area. By the early 1990s, population growth, cellular expansion, and the rise of fax and internet lines had put enormous pressure on the 612 number supply. On August 1, 1998, Minnesota's Public Utilities Commission implemented the 651 split, carving out Saint Paul and the eastern suburbs while Minneapolis retained 612. Over the following two years, additional splits created 763 for the northwestern suburbs and 952 for the southwestern suburbs, leaving 612 serving Minneapolis proper.

History Timeline

The Four-Way Twin Cities Split

The fragmentation of 612 into four separate codes mirrors patterns seen in other large US metros where explosive growth demanded new number capacity. Each code now serves a distinct quadrant: 612 for Minneapolis, 651 for the eastern arc anchored by Saint Paul, 763 for the northwest, and 952 for the southwest. For a look at how a comparable Midwest region managed similar number-exhaustion pressure in its state-capital corridor, see our guide to the 447 area code in central Illinois.

Cities and Communities in the 651 Zone

The 651 zone covers a mix of urban neighborhoods, established suburbs, and river valley towns that together define the eastern Twin Cities identity. Here are the major cities and regions that shape this territory.

Saint Paul — Minnesota's State Capital

Saint Paul is the largest city in the 651 zone and Minnesota's state capital, home to the State Capitol building and a concentration of state government offices employing tens of thousands. Major private employers include Ecolab — a global water, hygiene, and energy company headquartered in downtown Saint Paul — along with Regions Hospital and United Hospital, the city's two largest medical centers. The historic Summit Avenue district, the Science Museum of Minnesota, and Xcel Energy Center arena all anchor Saint Paul's mix of civic, cultural, and commercial life.

Maplewood, Roseville, and the North Suburbs

Maplewood is home to 3M's global headquarters — one of the world's most diversified technology companies, with operations spanning healthcare, industrial, and consumer markets. Its presence gives the 651 zone an outsized corporate and R&D footprint. Roseville anchors a dense retail and professional services corridor along Interstate 35W and Minnesota Highway 36. For a comparison with how a neighboring regional code serves a similarly layered suburban-commercial market, see our guide to the 309 area code in central Illinois.

Woodbury, Eagan, and the Southeast Suburbs

Woodbury is the fastest-growing community in the 651 zone, a planned suburb with a strong healthcare and professional demographic and easy access to both the Maplewood Mall retail corridor and the St. Croix River recreational area. Eagan, at the southern edge of the zone, hosts a major UPS airline operations center and a concentration of corporate offices. Inver Grove Heights and South St. Paul round out the southern tier, with roots in agriculture, food processing, and transportation along the Mississippi River.

Why Businesses Choose a 651 Number

A local 651 area code number signals to Minnesota clients that your business is part of the Twin Cities community. Local numbers generate higher answer rates than toll-free or out-of-state lines, and in a market where state contracting, healthcare procurement, and corporate vendor relationships all value local credibility, a Saint Paul area code can open doors a national number cannot.

• State government contracting — Saint Paul's concentration of state agencies drives steady demand for technology, consulting, and professional services; vendors with a 651 number reduce friction with procurement teams
• Corporate tech and R&D — 3M in Maplewood and Ecolab in downtown Saint Paul anchor a corporate ecosystem that purchases significant volumes of technology, facilities, and supply chain services
• Healthcare sector — Regions Hospital, United Hospital, and HealthEast Woodbury collectively employ tens of thousands and engage regularly with vendors and suppliers
• Education and nonprofits — Hamline University, Bethel University, and a dense Twin Cities nonprofit sector serve the greater Saint Paul community and engage regularly with service providers
• Remote routing — forward all 651 calls to any device from any location worldwide, keeping your team reachable under a Minnesota number

Industries That Benefit Most

State government contractors bidding on technology or facilities projects in Saint Paul, technology vendors supplying 3M and Ecolab, and healthcare suppliers serving Regions Hospital and United Hospital all gain immediate credibility with a local number. Law firms and financial services companies working with Minnesota state agencies, and logistics providers with routes through the Twin Cities I-94 and I-494 corridor, also benefit from projecting a local Saint Paul presence.

651 Scam Calls: What You Should Know

The 651 area code is a fully legitimate Minnesota code used every day by residents, state agencies, hospitals, and corporations across the eastern Twin Cities. Like every US area code, it can be spoofed — a scammer can make a call appear to come from a 651 number even when it does not. Receiving such a call is not itself a warning sign; the vast majority are genuine. For the authoritative explanation of how caller ID spoofing works, see the FCC guide on spoofing and caller ID.

Common 651 Scam Tactics

Spoofed 651 calls frequently impersonate Xcel Energy — the primary electricity provider for the Twin Cities — with callers claiming an overdue bill and threatening disconnection unless an immediate payment is made by phone. Minnesota Department of Revenue impersonation scams are also active, exploiting the code's association with Saint Paul's government agencies; callers may claim an outstanding tax liability requiring urgent personal verification. IRS and Social Security Administration spoofing is consistent across the metro, and Medicare fraud targeting older residents in communities like White Bear Lake and Roseville has been reported to state consumer protection authorities.

How to Protect Yourself

• Never share personal or financial information with an unsolicited caller, regardless of what area code appears on screen
• Use a reverse-lookup service before returning any unfamiliar Twin Cities number
• If a caller claims to be from a government agency or utility, hang up and call that organization's official number directly
• Register on the National Do Not Call Registry to reduce unwanted telemarketing to your line

The Complete 651 Picture

The 651 area code has served Saint Paul and the eastern Twin Cities since 1998, when the explosive growth of the metro forced the split from the original 612 code. Today it covers Minnesota's state capital, the global headquarters of 3M and Ecolab, and a broad arc of residential, commercial, and institutional communities from Maplewood to Stillwater. The zone operates in Central Time, carries no overlay, and includes some of the most economically significant employers in the Upper Midwest.
