How To Get An Independent Contractors Social Security Number When They Refuse To Submit A W-9 Form (Request For Taxpayer Identification Number and Certification)? Are you a business owner who is preparing a 1099 for the income you paid an independent contractor? My name is Lance Casey and I am a private investigator. For over the past 20 years I have been finding Social Security Numbers and sensitive, non-public information for attorneys, judgment collectors, business owners and people just like you. It's perfectly legal to get someone's social security number to issue a 1099. All I need to find someone's social security number is their full name, date of birth, address and your permissible purpose. Click the link either above or below, and fill out the contact form. After you pass your compliance interview, you will receive the independent contractor's social security number to complete the 1099-MISC.
