You mean a seed? Simple!

 Random.seed = Random.Range(int.MinValue, int.MaxValue);
 // if 2d
 offset = new Vector2(Random.Range(0, 10000), Random.Range(0, 10000));
 // or this if 3d
 offset = new Vector3(Random.Range(0, 10000),Random.Range(0, 10000),Random.Range(0, 10000));

So when you always put the same seed in Random.seed the offset will always be the same. When you get your data from the perlin noise just add the offset to your coordinates.
