Satan will be bound for a thousand years - Revelation 20:1-3
And I saw an angel come down from heaven, having the key of the bottomless pit and a great chain in his hand. And he laid hold on the dragon, that old serpent, which is the Devil, and Satan, and bound him a thousand years, And cast him into the bottomless pit, and shut him up, and set a seal upon him, that he should deceive the nations no more, till the thousand years should be fulfilled: and after that he must be loosed a little season.
Before the one thousand year reign of Jesus, Satan will be bound and thrown into the bottomless pit for the entirety of Jesus’ reign. John lists four names of the “tempter” in verse 2 – dragon, old serpent, Devil, Satan. During the reign of Jesus, Satan will not be able to deceive the nations.
