Should I Ever Give My Social Security Number Out On-Line?
No, you shouldn’t. In our on-line Voter Registration Section, some states such as Hawaii, Kentucky, South Carolina, Tennessee, Virginia, Ohio, and New Mexico, may ask for your social security number to prevent fraudulent registration and voting.
At no time does PresidentialElection.com need your Social Security number for any reason. In the states that request a social security number for processing, we have added a safety feature in the description “If you do not want to type in your Social Security number in this form for security reasons, you can leave it blank. When you print your form to mail, you will still have the option to write it in manually before you mail in your registration application if your state requires it. We recommend typing in just the first three numbers and writing the rest in by hand after printing.. The referenced states may need that information to process your application. If you have any questions about any fields, just point your curser at the question mark beside each field.
