Where’s my lot number?
Look for a small sticker toward the top of your cylinder. You can still search for partial lot numbers if the sticker is slightly damaged. If your lot number is missing, completely damaged, or you’re having trouble locating a record, please call our Support Center toll-free at 888-639-2474.
