A W-9 form includes two parts. Part I is identification data about the payee. Part II is the certification, or signature, confirming that the ID info is correct. It can be called a “request for taxpayer identification number and certification” but “W-9” is more typically used.
W-9s can be e-signed and sent back to you digitally, saving time for contract workers and companies alike.
