How do I check a Coast batch code?

Enter the batch (lot) code printed on the packaging or crimp into the checker — Coast codes decode into the manufacture date and an expiration estimate. The code (also called a lot number or serial number) encodes the production date.

Where to find your Coast batch code

The Coast 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):

What a Coast batch code looks like on cosmetic packaging — a short embossed lot/date stamp, not the barcode

The Coast 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.

Bottle / jar — stamped on the base.
Tube — near the crimp or seal at the closed end.
Boxed fragrance — a flap or side of the outer box (and often on the bottle base too).
Compact / palette — the underside, or inside the pan.

About Coast batch codes

Coast codes encode the production date.

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 Coast 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 Coast product is authentic. Buy from Coast or an authorised retailer, and compare the packaging, print quality and seal with one you know is genuine.

Does Coast expire?

Yes — like all cosmetics and fragrances, Coast 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.
