You should verify with your local telephone company that your number is unlisted or non-published: not available to directory assistance and not published in the phone book. You can instruct them to delete your listing from directory assistance.

If you know you have an unlisted number, it's possible that your number was listed in the past and remains in the database.

Sometimes an unlisted number isn't printed in the phone book but is given out by directory assistance, which is similar to how 555-1212.com gets its data. Check with your local telephone company for their definitions.

If you don't want your listing to appear on 555-1212.com, please contact your telephone service provider.
