Here are the first steps to do:
Check if the shipping address you provided is correct.
Look around the delivery location for your package. See if someone else accepted the delivery. Some packages travel through multiple carriers; check the mailbox or wherever else you receive mail.
Also, wait 36 hours - in rare cases packages may say delivered up to 36 hours prior to arrival.
