The Entry Codes feature allows you to require users to enter a valid code before they can submit your promotion form. This is useful for controlling access and validating participation.
You can upload a CSV file of codes, and ViralSweep will automatically verify whether each code is valid.

FAQ
What does “Each Code Can Only Be Used Once” mean?
Set to YES if every code is unique and should only be used once (e.g. one code per product)
Set to NO if codes can be reused (e.g. a small set of shared codes)
Why are users seeing an “Invalid Code” error?
The most common cause is that all codes have already been used.
If one-time use is enabled, codes become invalid after use
To fix this:
Re-upload your code file
Or set the option to NO to allow reuse
