M.A.C Batch Code Location Guide

Find the right M.A.C batch code before decoding: check box, bottle, tube crimp, seal, and avoid barcodes, shade numbers, or SKU codes.

Locate the correct M.A.C batch code before using the checker. Failed lookups often come from entering a barcode, shade reference, or incomplete print instead of the production lot.

  • M.A.C is usually checked from a short makeup lot code near shade or product references.
  • Start with outer box bottom or compact base, then confirm another package area if the print is faint.
  • Use one complete printed string from one location; do not merge box and bottle fragments.

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.

The correct code is usually a compact alphanumeric string printed away from the main barcode and marketing copy.

  • 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 long barcode number, shade number, SKU, ingredient registration number, or volume marking. Those strings identify the product, not the production batch.

If several M.A.C codes appear, enter the shortest complete batch-like string first and compare it against the same print on another package area.

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. The actual batch code is usually shorter and less prominent.
