Batch numbers, serial numbers, and other product markings help the manufacturer identify the product and its production run. These numbers may appear on a label, a nameplate, or as a print located on the underside or back of the product, or on its packaging.

Please take a photo of the entire marking so that both the text and the numbers are legible. Note that item numbers and batch numbers are not always the same thing.

If you cannot find a number, please let us know and attach a photo of whatever markings are present. A photo of the underside of the product or the label on the packaging can also be helpful. You should still contact us regarding the issue, even if you are unable to locate a batch number.
