Most likely M.A.C code locations
For M.A.C, start with the outer box bottom. If the outer box is missing, move to the compact base and then the tube crimp.
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 outer box bottom under bright side light.
- Check the compact base under bright side light.
- Check the tube crimp 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 M.A.C 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.
M.A.C product and package context
Inspect the base sticker, tube, compact, bottle, or carton for a compact production mark. Shade names, finish labels, color numbers, and barcodes are not batch codes.
Where is a MAC makeup lot found? Start with the base sticker or container, then compare the compact mark with the outer carton if available.
