Geographic Coverage
The 620 area code covers southern and western Kansas, including Hutchinson north of Wichita, Great Bend in the center, the legendary cattle town of Dodge City, Garden City and Liberal in the southwest near the Oklahoma and Colorado borders, and Pittsburg, Coffeyville, and Winfield in the southeast. It is by far the largest area code by land area in Kansas.
Time Zone
Most of the 620 area code observes Central Time (CT), following Central Standard Time (UTC−6) in winter and Central Daylight Time (UTC−5) in summer. The exception is the far-western border counties of the region – such as Greeley, Hamilton, and Wallace – which observe Mountain Time (MT), one hour behind, because they sit on the Colorado line. Both zones observe daylight saving time from mid-March through early November.
Tip: Business hours across the 620 region generally run 9:00 AM to 5:00 PM local time, Monday through Friday.
How to Dial a 620 Number
Area code 620 is not part of an overlay, so it has traditionally allowed 7-digit local dialing. However, 10-digit dialing is now the recommended nationwide standard, and dialing the full 10-digit number (620 + the line number) always works reliably. For international callers, dial your country’s exit code, then +1 (the North American country code), then 620, followed by the seven-digit local number.
Scam Alerts for the 620 Area Code
Like every U.S. area code, 620 has been used by scammers who spoof local numbers to appear trustworthy. Residents in Hutchinson, Dodge City, Garden City, Liberal, Great Bend, Pittsburg, Coffeyville, Winfield should stay alert to the following common tactics:
| Scam Type | What to Watch For |
|---|---|
| IRS / Tax Scams | Callers claiming you owe back taxes and threatening arrest unless you pay immediately. |
| Utility Shut-off | Fake Evergy callers demanding instant payment to keep your power on. |
| Farm / Equipment Scam | Fraudulent online listings for tractors, cattle, or farm equipment aimed at rural buyers. |
| Storm Repair Scam | Fake contractors demanding upfront payment for tornado or hail damage repairs. |
If you receive a suspicious call from a 620 number, take these steps to protect yourself:
- Do not share personal information such as Social Security numbers, bank details, or passwords over the phone.
- Hang up and verify by calling the organization back using an official number from its website.
- Report the call to the FTC at reportfraud.ftc.gov and to the Kansas Attorney General’s Consumer Protection Division.
- Block the number and consider registering with the National Do Not Call Registry.
Red Flag: Legitimate agencies such as the IRS, Social Security Administration, or your local utility company (Evergy or Kansas Gas Service) will never demand immediate payment by gift card, wire transfer, or cryptocurrency. Any 620 caller making such a demand is a scammer.
