They have a customer service counter just let them know you are applying in the entrance the will guild you very simple process
Go inside one of the many stores in your area, there's a front desk where you can apply.
Go to your local warehouse. Go to the desk that's inside next to the exit area/merchandise returns or just ask the person at the entrance/exit where to go. You'll need to bring your ID, and if you're getting a shared membership the other person will need to have the same address on their ID.
You can apply for a membership by stopping by Costco's membership desk. They'll be happy to get you signed up!
Go to the store.
