Visual location guide

Where to find cosmetic batch codes.

Check the most common locations first, learn what the code looks like, and reveal faint markings without damaging the packaging.

Look here first

The three most common locations

Start with these three surfaces. The batch code is separate from the retail barcode; the precise position varies by product and packaging.

Batch code printed on the base of a cosmetic bottle01

Bottle base

Turn bottles and jars over first. Look around the base, bottom label, and lower rim.

Batch code stamped on the crimped end of a cosmetic tube02

Tube crimp

Inspect the folded seal at the end of the tube for stamped or inkjet-printed characters.

Batch code printed on cosmetic outer packaging beside a barcode03

Outer packaging

Check the bottom panel, side flap, and the area beside the barcode on the carton.

Base or bottom edge of the container

Turn the product over first. Most bottle and jar codes sit on the base.

  1. 01Bottom of the bottle or jar
  2. 02Lower edge near the base
  3. 03Side of the container close to the bottom
  4. 04Underside of the cap or lid

Recognize the code

Batch code, not barcode

A batch code is a short manufacturing identifier. A barcode is the longer retail code printed below vertical black lines.

Look for a separate string of letters or numbers, sometimes introduced by “LOT” or “BATCH”. These examples illustrate appearances, not a shared date formula. Length varies by brand.

Reveal faint or hidden markings

  • Use angled light

    Rotate the package slowly under a bright lamp to reveal shallow embossing or laser etching.

  • Take a close-up photo

    Your phone camera can enlarge tiny dot-matrix printing and improve contrast.

  • Check the outer box

    Some brands place the code only on the carton, usually near the barcode or on a flap.

  • Feel the surface

    Run a fingertip over the base or seam to detect characters you cannot see clearly.
