"...If you’re going away for a while, take advantage of the Postal Service Hold Mail service. The USPS will keep your mail safely at your local Post Office™ until you return. Schedule the service up to 30 days in advance, or by 2AM CST (Mon-Sat) on the start date. Each address can have one Hold Mail scheduled at a time. All mail will be held, rather than an individual's mail. Fill the form out online..."
