Need to pull multiple numbers from column b with same prefix in column a - separately

Hello,
I'm trying to pull multiple store numbers from sheet 1 to sheet 2. These store numbers all have a trailer number associated with them, IE. A1 = trailer #, B1 = store number.
I need a formula (could be a macro if multiple are needed) to pull all stores, in separate cells, with the same trailer number to a column in sheet 2
