Yes, putting a luggage tag on your suitcase is an essential safety measure in 2026, despite the rise of digital tracking. While many travelers now use AirTags or Tile trackers, a physical tag is the only way for airline staff to identify your bag if the internal airline "barcode" tag is torn off during transit—a common occurrence in high-speed sorting systems. A good luggage tag should include your name, phone number, and email address, but it is recommended to use a tag with a privacy flap to hide your home address from prying eyes in the terminal. In 2026, "Smart Tags" with QR codes are popular, allowing someone who finds your bag to scan the code and contact you through a secure platform without seeing your personal details. It provides a vital "low-tech" backup to ensure your bag is returned if technology or the airline's system fails.
