Most likely Olay code locations
For Olay, start with the box bottom. If the outer box is missing, move to the jar base and then the pump bottle base.
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 box bottom under bright side light.
- Check the jar base under bright side light.
- Check the pump bottle base 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 Olay 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.
Olay product and package context
Look on the jar or bottle base, rear label, tube crimp, or carton for a compact production marking. SPF values, regimen names, sizes, and UPC barcodes are unrelated.
Wide-mouth creams depend on clean handling and PAO, while a closed pump reduces direct contact. Any printed expiration on an SPF product should be used before the lot estimate.
