The 23-year-old full back has been unable to nail down a regular spot in the Trotters first team since arriving from Blackburn in the summer of 2000.
He spent the bulk of last season on loan at Blackpool's Second Division rivals Notts County and played a key role in The Magpies escaping relegation.
Richardson becomes Seasiders manager Steve McMahon's second recruit from Bolton this week after he lured veteran defender Colin Hendry to Bloomfield Road on a temporary basis.
Richardson will be hoping to use the move to hone his match sharpness after a recent trial at Bradford City failed to result in a transfer.
