Where is the batch code?
It is a short separate stamp — here is where it usually hides on different packs.
After opening (PAO)
What does the open-jar (PAO) symbol mean?
The little open-jar icon with a number like 12M or 24M is the Period After Opening — how many months a product stays good once you first open it. After opening, this becomes the limit even if the batch code date is recent.

What's the difference between shelf life and expiration date?
Many cosmetics do not print an expiry date. When a batch-code format is supported, we show its production period and general shelf-life context. Do not treat that result as a guaranteed expiry; follow the pack's date, PAO symbol, storage instructions and product condition.
Frequently Asked Questions
Everything you need to know about decoding cosmetic and perfume batch codes.
What is a batch code?
A batch code is a short code printed on cosmetic and perfume packaging that identifies a production run. When the manufacturer's format is documented, decoding it can show when the product was made.
Is this batch code checker free?
Yes. Cosmetics Batch is completely free, requires no account, and processes codes securely on the server.
Where do I find my batch code?
It's usually a short stamped or embossed code on the base of a bottle, the crimp of a tube, or the bottom of the box — separate from the barcode.
What's the difference between shelf life and expiration date?
Many cosmetics do not print an expiry date. When a batch-code format is supported, we show its production period and general shelf-life context. Do not treat that result as a guaranteed expiry; follow the pack's date, PAO symbol, storage instructions and product condition.
Why can't my batch code be decoded?
Some brands change their coding over time, use region-specific formats, or don't encode the date publicly. Double-check you entered the stamped batch code (not the barcode), or try selecting the parent company instead of the sub-brand.
Do you store my batch codes or personal data?
No account is required and IP addresses are not included in our batch-code quality dataset. We may retain the code, brand, result, language, time and country-level code to improve decoder accuracy; see the Privacy Policy for details.
