Renew Your Number on No-Call List

If your phone number is on the Wisconsin’s No-Call List, you may want to renew your number by June 1st. The No-Call List keeps phone numbers for two years, after which the number must be re-registered with the Department of Agriculture, Trade, and Consumer Protection (DATCP). You can renew your number for another two years on the No-Call List by visiting DATCP’s website at or by calling 866-966-2255 (toll-free).
