M·A·C artist heritage
The Estée Lauder Companies' official profile records M·A·C's 1984 Toronto creation, 1994 ELC relationship and broad makeup-led product range. It is brand context, not a lot-code cipher or shelf-life rule.
MAC Cosmetics Batch Code Checker
Manufacturer: Estée Lauder Companies
Lipstick and lip cases: twist the bullet down and inspect the flat base label and any outer carton for a separate short lot mark. Keep the shade label and the long retail barcode visible in the wider photograph.
Where to find the code on MAC Cosmetics packaging
Compacts, blushes and palettes: inspect the underside label, carton flap and any printed mark on the case. Limited collections, refills and older Back-to-M·A·C packages can use different surfaces, so treat these as search areas rather than a universal MAC position.
- Foundation, mascara and tube products: inspect the bottle or tube base, rear wrap label and sealed crimp as applicable. Enter the short lot field, not an EAN/UPC, shade number, product reference or PAO value.

Evidence notes used in this MAC Cosmetics guide
The explanations and summaries are written directly on this page. The source names below show which official, regulatory and community material informed the editorial interpretation; no external reading is required.
M·A·C product formats
MAC's official product and employment material describes colour cosmetics, foundations, lashes, brushes and skincare. The range supports an exact-format inspection path rather than one universal package location.
M·A·C community questions
MAC Customer Service provides the appropriate escalation route when package, seller or lot information cannot be reconciled.
GUIDANCE
Where to start on MAC lipstick, foundation and palettes
M·A·C was created in Toronto in 1984 and has been part of The Estée Lauder Companies since 1994. Its current range spans colour cosmetics, foundations, lashes, brushes and skincare. That short context explains why a lipstick, Studio Fix foundation, pigment jar and limited-edition palette can use different labels; the exact product name, shade, finish, size and market should lead the inspection.
FACT
Find the short lot mark without entering the shade or barcode
A code-location check follows the physical format. Twist lipstick down and photograph the base, shade sticker and carton. For a compact or palette, include the underside label and carton flap. For foundation, mascara and tube products, inspect the base, rear wrap label and sealed crimp. Keep the retail barcode in the wider frame so it is not confused with the short lot field. Collection and regional packaging changes mean these are practical search routes, not one fixed MAC rule.
FACT
What the observed B23 marking can establish
The existing MAC gallery shows short three-character marks, including B23, but the photographed records contain no independent printed manufacture-date pair. No official MAC source located for this page publishes a decoding table, so the mark remains an observed identifier rather than a public date result. Read any printed date, PAO symbol and storage direction on the exact product before interpreting product life.
GUIDANCE
Read product life from the exact MAC formula and pack
Lifecycle guidance must follow the formula and opening history. Keep creams, liquids and eye products closed and clean; record the opening date; protect products from heat, direct sun and bathroom humidity. A dry powder, lipstick, mascara and liquid foundation should not inherit one shared duration. A change in smell, colour, separation or texture is a reason to stop and assess the item and its storage record.
GUIDANCE
If the MAC code is faint or unsupported
When a MAC mark is faint or unsupported, prepare a complete record: front and back, base, carton flap, barcode panel, shade, finish, size, market, seller and purchase date. Compare the same collection and format, then use MAC Customer Service or the retailer for an exact-pack question. Do not scrape off printing or replace the carton before documenting it.
MAC Cosmetics — FAQ
How do I check the expiry date of MAC foundation?
Check the exact bottle, carton or compact for a printed date, open-jar PAO symbol and storage directions. The short lot mark can add production context, but liquid foundation, mascara, eye products, lipstick and powder do not share one automatic lifetime. Record the opening date and keep the full product, shade, finish, size and market with any retailer or MAC Customer Service question.
What does a MAC batch code look like?
Short marks such as B23 are visible on some MAC packages, but MAC's public sources do not publish a brand-specific date cipher. The example helps identify the field to enter; it is intentionally not assigned a manufacture date here. Enter the complete short mark from the item, not the EAN/UPC barcode, shade number or product reference, and keep the exact product, size, market and printed package information with the result.
