Asking for zip codes tells a store what people from a certain area are buying. great information for targeted advertising. no store has ever asked me for my phone number, and I've spent a lot of time in Lowes, home Depot and OSH the last few months.
In Florida, Lowes will ask for your phone number if you're not paying with a credit or Lowes preferred card explaining that it's for the purpose of returns. The cashier won't argue if you refuse however and will process your transaction.
