Ask the realm owner for the seed
Check the realm settings if you have owner or operator access
Use a seed-finding tool only if you have permission and the realm allows it
Join the realm and use a seed map or structure locator if seed access is available
Export or download the world if you are the owner, then view the seed in world settings
Open the world in single-player if you have the realm download and check the world seed there
Use commands only if cheats or operator permissions are enabled
Contact the realm owner if you do not have access to the seed directly
