Area Code Information
Area Code Relief
The PSC is responsible for maintaning enough phone numbers for Wisconsin residents and businesses. As an area code approaches exhaust, the agency will work with industry and the public to develop solutions and timelines for those exchanges.
Because area code relief imposes costs on customers and providers, the Commission has adopted a number of policies (such as 1000 block pooling, etc.) to slow the use of number exhaust.
If you have questions or comments about area codes or numbering issues, please contact Peter Jahn at 608-267-2338, or via email at firstname.lastname@example.org.
Number portability is the ability to keep your telephone number when you change providers. For example, if you had the phone number 555-434-2457 with your AT&T landline, you can change to Charter and keep the 555-434-2457 number.
