Residents can request to have their phone numbers removed from residential listings. To have phone numbers removed, customers can contact their local phone companies to request an unlisted number.
To have their numbers removed from online directory services, individuals can write directly to the directory website. Many of these sites provide online forms to simplify this process.
Cellphone customers can also protect against unwanted calls by requesting that the carrier list the phone number as unpublished or unlisted when customers are signing up for a new service. If the retailer or online sign-up forms do not offer this option, the customer can call the carrier directly to request an unlisted number.
