Area Code Breakdown & District Mapping
Appleton is the largest city in the Fox Cities and a hub of the Fox Valley in northeastern Wisconsin, straddling the Fox River. Its numbers come from an overlay pair that shares the same geography:
- Area code 920 — serves northeastern Wisconsin and the Fox Valley, covering Appleton and Outagamie County (with parts of Calumet and Winnebago counties). This includes Downtown along College Avenue, the Lawrence University area, and neighboring Fox Cities communities such as Grand Chute, Menasha, Neenah, Kaukauna, and Kimberly.
- Area code 274 — an overlay introduced for the 920 region to add new numbers. It covers the exact same area, so a 274 number can belong to anyone in Appleton and the Fox Valley.
Area code 920 has served northeastern Wisconsin since 1997. As demand grew across the Fox Valley, the 274 overlay was added over the same territory rather than splitting the region, so existing customers kept their numbers.
Local Dialing Rules & International Calling
Because of the 274 overlay, the Appleton area requires mandatory 10-digit dialing on every call. Always include the area code, even for local calls.
- Local / domestic: dial 920-XXX-XXXX (or 274-XXX-XXXX).
- 11-digit: you can also dial 1-920-XXX-XXXX; the leading 1 is the country code for the US.
- International: dial your country’s exit code, then +1 920 XXX XXXX — for example, 00 1 920 XXX XXXX from the UK or Europe, or +1 920 XXX XXXX from any mobile phone.
Major ZIP Codes Covered
Appleton’s numbers align with ZIP codes including 54911 (central/downtown), 54913 (north/Grand Chute), 54914 (west), and 54915 (south/east), along with surrounding Fox Cities communities.
Spam & Scam Call Warnings for Appleton
Scammers frequently spoof local 920 and 274 numbers so calls look like they come from a neighbor or a local business. Appleton residents commonly report:
