Area Code Relief - Projected Exhaust Dates

When will Wisconsin’s area codes need relief?

The North American Numbering Plan Administration (NANPA) is responsible for forecasting when an area code will most likely exhaust and require the implementation of an additional area code.  The most recent projections were published in April 2016.  Wisconsin’s current projected exhaust dates are:

Note: NANAP does not forecast a specific exhaust date for area codes when the projected exhaust date is in excess of 30 years.

If you have questions on area code issues or exhaust dates, please contact Peter Jahn at 608-267-2338 or email Peter.Jahn@wisconsin.gov .
