You can find the serial number on the sticker located on the bottom of your bottle, or on the barcode of the box. For the LARQ Pitcher, this is on side of the PureVis Wand and the box. It is an alpha-numeric sequence starting with BD, BS, BC, BFDMB, or P and ending in a number. (e.g. BDMB050A00001311; or PMB00001311).
