If your school or company has a site license for WPS Office, your IT department may distribute official redeem codes. These usually auto-update while you remain affiliated with the organization.
A redeem code for a 1-year Premium plan does not give you free updates forever. Once the year expires, your Premium features lock, reverting you to the Free version (with watermarks on PDF export). Major version upgrades (e.g., from WPS 2020 to WPS 2023) also typically require a new license. redeem code for wps office premium free upd
