IRS regulates the use of PIN and has certain rules to follow before they provide you a PIN. You can use this link provided by IRS that contains the details to get a PIN: Use an On-Line Signature PIN to e-File Employment Tax Forms.
You can contact IRS' e-help Desk through this link: Contact IRS for More Information.
