Einführung
The 608 area code belongs to southwestern Wisconsin, including the state capital, Madison, along with Janesville, Beloit, La Crosse and Wisconsin Dells.
It went into service in 1955, and since September 15, 2023 a second code, 353, has been available for new lines in the same region.
Maybe a 608 number called and you want to place it, or maybe you need a Madison-area line for a business.
Either way, the sections below cover the counties inside the region, the local time, how the 353 overlay came about, the dialing rules and a quick way to size up an unknown caller.
- 608 serves all or part of 21 counties in southwestern Wisconsin, led by Madison.
- The code has been in service since 1955, and the Public Service Commission of Wisconsin approved the 353 overlay on September 16, 2022.
- 353 numbers could be assigned starting September 15, 2023, but only once every assignable 608 prefix is taken.
- Local calls take ten digits, a rule that came with the 2021 changes for 988, and the whole region is on Central Time.
Where Is the 608 Area Code?
Area code 608 is in the United States, in the southwestern part of Wisconsin. NANPA describes the 608 region as the southwestern portion of the state including the capital, Madison, and the Public Service Commission of Wisconsin calls the overlay area southwest and southcentral Wisconsin.
Its reach is wide. The same code serves Madison, Middleton, Sun Prairie and Stoughton, as well as Janesville, Beloit, Monroe, Platteville, Wisconsin Dells and La Crosse.
Other Wisconsin area codes, among them 262, 414 and 920, serve other parts of the state. Our Wisconsin area codes page lists them all.
Cities and Counties in the 608 Area Code
NANPA's planning letter for the 353 overlay lists 21 counties that 608 serves in whole or in part: Adams, Buffalo, Columbia, Crawford, Dane, Grant, Green, Iowa, Jackson, Jefferson, Juneau, La Crosse, Lafayette, Marquette, Monroe, Richland, Rock, Sauk, Trempealeau, Vernon and Walworth.
Some of those counties sit only partly inside the region, so a county name won't confirm which code a number carries. The communities below are the ones official and carrier sources name:
| Named by | Communities |
|---|---|
| NANPA planning letter, November 2022 | Madison, Beloit, Janesville, La Crosse, Middleton, Monroe, Stoughton, Sun Prairie, Wisconsin Dells |
| Public Service Commission of Wisconsin, August 2023 | The same towns plus Platteville |
| AT&T area code listing | Also names Fitchburg among the largest communities |
608 Area Code Time Zone (Central Time)
Clocks across the 608 region show Central Time. Federal time-zone rules put all of Wisconsin in the Central zone, so Madison, Beloit and La Crosse always agree on the hour.
Wisconsin follows daylight saving time. Central Standard Time is UTC−6; from 2 a.m. on the second Sunday in March until 2 a.m. on the first Sunday in November, the region runs on Central Daylight Time, UTC−5.
Someone in Boston who dials at 3 p.m. reaches Madison at 2 p.m.
608 and 353: One Area, Two Area Codes
For nearly seven decades, 608 covered the region by itself. It went into service in 1955, formed from parts of Wisconsin's two earlier numbering areas, 414 and 715.
By 2022 the pool of 608 prefixes was running low. NANPA filed notice with the Public Service Commission of Wisconsin in June 2022 to begin relief, and on September 16, 2022 the commission approved an all-services distributed overlay in Docket 5-TN-112.
An overlay adds the new code to the existing map, so no current customer had to change numbers.
| Milestone | Date |
|---|---|
| Commission approves the 353 overlay | September 16, 2022 |
| NANPA publishes its implementation plan | November 9, 2022 |
| Network preparation and customer education begin | December 15, 2022 |
| Carriers may start ordering 353 prefixes | July 11, 2023 |
| 353 goes into service | September 15, 2023 |
In August 2023 the commission said 608 was expected to run out of assignable prefixes by the first quarter of 2024 or sooner. One rule sets this overlay apart: NANPA assigns 353 prefixes only after every assignable 608 prefix has been assigned.
A 353 number marks a line drawn from the newer pool, not a different part of the state.
Is 608 a Country Code? What That Search Really Means
No. 608 is an area code in the United States, not a country code. Searches such as "608 country code" and "area code 608 united states" tend to come from someone looking at a number like +1 608 555 0129.
Read it left to right: +1 is the country code for the United States, 608 places the line in southwestern Wisconsin, and the last seven digits identify the subscriber.
To share a 608 number with contacts overseas, write it as +1 608 plus the seven digits, a format any phone in the world can dial. Each part is broken down in our explainer on the US phone number format.
608 Area Code vs ZIP Codes
A "608 zip code" doesn't exist, though the search is a common one. Telephone numbering and ZIP Codes come from separate systems: one tells the phone network where to route a call, the other tells the Postal Service where to carry a letter.
The 21 counties of the 608 region contain many ZIP Codes, and none of them is tied to the area code. For the right ZIP Code for an address in Madison, Janesville or a small town near La Crosse, use the USPS lookup tool.
How to Tell If a Call From 608 Is Legitimate
What Caller ID Can and Can't Tell You
A 608 number shows where a line was first assigned, not who is using it right now. According to the FTC, scammers can display any name or number they like, so a call that appears to come from Madison could start on another continent.
Warning Signs Worth Acting On
- Urgency: you're told to decide, pay or confirm details immediately.
- Unusual payment: gift cards, wire transfers, cryptocurrency or payment apps, which the FTC ties to scams because the money is hard to recover.
- A supposed government official asking for your Social Security number.
- A recorded message asking you to press a number.
- Any request for a verification code, PIN or password.
Reporting and Blocking
File a fraud report with the FTC at ReportFraud.ftc.gov, and log unwanted telemarketing at DoNotCall.gov. As the FTC points out, the registry won't deter criminals, so block repeat numbers through your phone's settings, your carrier or a call-blocking app.
How to Dial a 608 Phone Number
Local calls in the 608 region already required ten digits before 353 went live.
Under the FCC's 988 order, 608 was one of 82 area codes that still allowed seven-digit dialing while using 988 as a local prefix, so providers there had to switch to ten-digit dialing.
| Type of call | What to dial | Note |
|---|---|---|
| Local call within 608/353 | 608 or 353 + seven digits | Some providers also accept 1 + ten digits |
| Toll or long-distance call | 1, then the area code and seven-digit number | Also how callers elsewhere in the US reach the region |
| Operator-assisted call | 0 + area code + seven digits | For collect calls and similar operator services |
| From outside the US | Your international access code, 1, 608, the seven-digit number | Written as +1 608 555 0129 |
According to the Public Service Commission of Wisconsin, three-digit numbers still work, including 911 and 988, the Suicide & Crisis Lifeline.
How to Get a 608 Phone Number for Your Business
Businesses serving Madison, La Crosse or Janesville often want a local area code on their caller ID, and a cloud number provides one without renting an office in the region. Because 608 and 353 share one map, either code works.
