If you mean is Alsager in Cheshire, then the answer is absolutely YES!
Well, technically it is in Cheshire East now, since 1st April 2009....it has a Stoke-on-Trent postal address, but postcodes are of course just there to assist the Royal Mail with delivery and have no real bearing on actual locations (as everyone on the outskirts of London and many people on the English/Welsh border will know!).
