Where to find your Under Twenty batch code

The Under Twenty batch code is a short, usually embossed stamp of letters and numbers — never the barcode. Here’s what it looks like on typical packaging (the code is the short embossed stamp, not the long barcode):

The Under Twenty batch code — also called the lot code, lot number or serial number — is a short 4–8 character stamp of letters and numbers, usually embossed rather than printed in ink, and it is never the barcode. On a bottle or jar look at the base; on a tube look near the crimp/seal at the end; on a boxed perfume or fragrance check a flap or side of the box; on makeup check the underside of the compact or inside the pan.

About Under Twenty batch codes

We can't decode Under Twenty's batch code format yet. Check the printed expiration or best-before date on the pack, the PAO open-jar symbol, and the product's smell and texture.

Most unopened cosmetics and fragrances keep for about 30–36 months from manufacture. Once opened, follow the PAO (open-jar) symbol — it usually matters more than any printed expiration date.

Can the batch code tell me if my Under Twenty is authentic? Not on its own. A code that decodes to a sensible date is a good sign, but counterfeiters copy real codes from genuine packs, so a valid code cannot prove a Under Twenty product is authentic. Buy from Under Twenty or an authorised retailer, and compare the packaging, print quality and seal with one you know is genuine.

Does Under Twenty expire?

Yes — like all cosmetics and fragrances, Under Twenty products have a limited shelf life. Unopened they typically last 30–36 months from the manufacture date, and the batch code above tells you how old yours already is. After opening, the PAO (open-jar) symbol — e.g. "12M" — is a better guide than any printed expiration date.
