Where to find your Blue Dot batch code

The Blue Dot 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 Blue Dot 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 Blue Dot batch codes

We can't decode Blue Dot'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 Blue Dot 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 Blue Dot product is authentic. Buy from Blue Dot or an authorised retailer, and compare the packaging, print quality and seal with one you know is genuine.

Does Blue Dot expire?

Yes — like all cosmetics and fragrances, Blue Dot 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.
