From the Tile page:
"Our new Sticker has a 150 ft or 46m range. Slim and Mate each have a range of 200 ft or 61m. Pro features our longest range, coming in at twice the range of Mate and Slim, measuring 400 ft or 122 m. However, as with all wireless technologies, different environments impact the effective range of Bluetooth signals. If your Tile is out of Bluetooth range, you can check its last known location on the app. This information is automatically updated whenever anyone in the Tile community comes within Bluetooth range of your Tile. All location and user information is secure and used exclusively for finding accuracy. Tile does not sell any user data."
