You can buy a UPS shipping label directly through the official UPS Create a Shipment tool. The process involves entering your shipping and destination addresses, selecting a service level (like Ground or Next Day Air), and paying for the postage online.

If you don't have a printer, you can take your package to a local UPS Store. They can help you create the label and print it for you, often for a small service fee.

If you are looking for physical, blank labels or specific carrier stickers to use with your own printer, you can find them from various retailers: Create and Print Shipping Labels | UPS - United States

The most direct way is to use the UPS website to generate a PDF label that you can print at home.

When you buy a label online, UPS often provides a mobile UPS Shipping QR code. You can show this at a UPS Store, and they will print the label for you on-site. UPS Shipping Supplies & Physical Labels
