To ensure that your shipments are delivered to you and not returned to sender, please indicate on or near your hours of operation signage that you’re still accepting deliveries, even though your business may be closed to the public. You can also leave specific delivery instructions with your signage.
Another suggestion is to sign up for a UPS My Choice account to manage your deliveries. It’s fast and easy and allows you to receive alerts, provide delivery instructions and set packages for pick up at a UPS Customer Center.
