Most likely Garnier code locations
For Garnier, start with the bottle back. If the outer box is missing, move to the tube crimp and then the box flap.
Check the label around each marking to distinguish the production lot from product references; position and character count alone do not identify a lot.
- Check the bottle back under bright side light.
- Check the tube crimp under bright side light.
- Check the box flap under bright side light.
Numbers to ignore
Do not enter the retail EAN/UPC product number, shade number, SKU, ingredient registration number, or volume marking as the batch. Some scannable codes contain additional fields; use only an explicitly identified lot field, not the entire scan.
If several Garnier codes appear, identify the production lot from its label and the instructions for that product. Length alone cannot identify it. Keep every mark with its original location and never trim a longer identifier to make it fit.
When the print is hard to read
Embossed or low-contrast batch codes are easier to read with side lighting. Take a photo, zoom in, and preserve leading zeroes, separators, and letter case.
If the box and container disagree, check whether one string is a product reference. Preserve both markings separately while confirming their purpose.
Garnier product and package context
Find the compact lot on a bottle base, rear label, tube crimp, sachet, or carton. Hair-color shade numbers, numbered kit steps, SPF values, sizes, and UPC barcodes are not production lots.
Garnier instructs users to perform the allergy test 48 hours before every hair-color application and to use mixed color immediately. Do not infer that every component shares one visible code; sunscreen follows any printed expiration before a decoded date.
