Spreadsheet formula extract zip code from address

I have cells in column A that contain info as shown below, where the property address includes a zip code. This zip code can be one of seven different option, but always 5 digits.

I need a function that says:

IF the cell contains zipcode1, zipcode2, zipcode3, etc., then copy that zipcode to the next cell over.

Any help?
