Cosmetic Batch Check is a multilingual tool for decoding batch codes found on skincare, makeup, perfume, sunscreen, haircare, and other beauty products.

Select a brand, enter the short batch code printed or embossed on the packaging, and receive production-date and product-age context based on that manufacturer’s coding format.

Brand-specific guides also help users distinguish the correct batch code from barcodes, shade numbers, product references, and other markings commonly found on cosmetic packaging.

### Key features

- Batch-code checking for 2,000+ beauty brands

- Brand-specific decoding rules and examples

- Guides for locating batch codes and lot numbers

- Production-date and freshness context

- Support for multiple languages

- Mobile apps for iOS and Android

- AI-enhanced checks for difficult or unusual codes

The decoded result is intended as a practical production-date clue rather than a replacement for an official expiry label. Users can compare it with the PAO symbol, printed dates, storage history, scent, texture, color, and packaging condition.

Cosmetic Batch Check makes it easier to understand the age and freshness of beauty products before buying, opening, or continuing to use them.
