What barcode scanner can reliably scan pallets from about 20 feet away?

The Zebra DS3600 extended-range models, especially the DS3678-ER, are designed for this kind of warehouse use and should be able to handle a distance around 20 feet. They’re rugged enough for daily pallet and warehouse work, so a used unit from a reputable seller could be worth considering. Make sure you get the correct cradle, battery, and connection method for the tablet.

You may be able to save money with a refurbished or used long-range model, but verify that it includes a healthy battery and the proper charging or communication base. Also check compatibility with the tablet’s operating system and whether it connects through Bluetooth, USB, or a keyboard-wedge mode. Put the labels somewhere visible and protected; temporary labels on stretch wrap may need frequent replacement.

Datalogic, Honeywell, and Zebra all make solid long-range handheld scanners. I wouldn’t focus only on the cheapest option because warehouse scanners get dropped and handled roughly every day. A dependable rugged model will usually cost less in the long run than replacing a budget scanner repeatedly. If the scanner is paired with managed tablets, device-management software can also simplify setup and control.

Distance isn’t the only factor—the physical size and print quality of the barcode matter a lot. For a scan from roughly 20 feet, the bars may need to be around three inches tall or larger, depending on the barcode type, lighting, label contrast, and scanner model. Test a sample label at the actual distance before printing a whole batch.
