Area Code Breakdown & Neighborhood Mapping
Area code 651 serves Saint Paul and the entire east metro. It was created when the original 612 region was split, taking over the capital city and the suburbs east of the Mississippi River. Today a 651 number reads clearly as an east-metro line.
Twin Cities Core
All Saint Paul districts fall under 651: Downtown and Lowertown, Summit-University and Cathedral Hill, Highland Park, Macalester-Groveland, the West Side, the East Side, Como, and Frogtown. The code also covers nearby suburbs including Maplewood, Roseville, and Woodbury.
Suburbs vs. Greater Minnesota
West across the river, Minneapolis uses 612. The northwestern suburbs use 763 and the southwestern suburbs such as Bloomington use 952. Beyond the metro, southern Minnesota uses 507, the north uses 218, and central Minnesota uses 320.
Local Dialing Rules & International Calling
Minnesota uses mandatory 10-digit dialing. Always dial the area code plus the seven-digit number, even for calls within Saint Paul. For domestic long distance, add a leading 1 (1 + 651 + number). To reach a Saint Paul number from abroad, dial your country’s exit code, then the U.S. country code +1, then 651 and the local number. Mobile users can dial +1 651 directly.
Major ZIP Codes in Saint Paul
Saint Paul ZIP codes generally fall in the 55101–55130 range. Common examples include 55101 and 55102 (Downtown/Lowertown and the West Side), 55103 and 55104 (Frogtown and Summit-University), 55105 (Macalester-Groveland), 55106 and 55130 (East Side), 55107 (West Side), 55108 (St. Anthony Park), and 55116 and 55118 (Highland Park area). Administrative ranges extend into the 55140s and beyond.
Cell Phones & Number Portability
Because of federal number portability, a 651 number no longer guarantees the caller is physically in Saint Paul. Residents who move away often keep their original 651 mobile number, and newcomers may arrive with codes from other states. When you sign up for new service in the east metro, carriers typically assign a 651 number, but the code that matters for dialing is whatever appears on the line — always dial all ten digits regardless of where the person lives now.
Spam & Scam Call Warnings in Saint Paul
East-metro residents report the same robocall trends as the rest of the Twin Cities. Common tactics include:
- Neighbor spoofing: Fraud calls faking a 651 prefix so they appear local. Screen unfamiliar callers even when the number looks like Saint Paul.
- Utility shutoff threats: Callers impersonating Xcel Energy or Saint Paul Regional Water demanding instant payment by gift card. Legitimate utilities never do this.
- Government impersonation: Fake IRS, Social Security, or Ramsey County “warrant” calls threatening arrest unless you pay.
- Medicare and warranty robocalls: Automated pitches fishing for personal or insurance information.
