I have a serial number
You may receive a license serial number when you or your Symantec Partner purchased the license. If you have a license serial number, select this option.
If you are an E-flex (Symantec Enterprise Options) customer and have an E-flex-generated serial number, select I have a Symantec License File.
I have a Symantec License File (.slf)
In most cases, you receive a Symantec license file (.slf file) in an email from Symantec shortly after you complete the purchase process. The file arrives attached to the notification email as a .zip file. If you have received a .slf file, select this option.
You must extract the .slf file from the .zip file before you can use it to activate your product license.
The .slf file contains the information that is unique to your license. To avoid corrupting the license file, do not alter its contents. You may copy the file for your records.
As of April 1st, 2017, Symantec is no longer accepting new enrollments in the E-flex program.
