MAC Batch Code Format
This checker understands the MAC format — batch/factory + month + year (e.g., c79, c11). Anything outside that structure is flagged instead of being decoded on a guess.
Format: batch/factory + month + year (e.g., c79, c11)
Examples: c79, c11, s44, aa1
Shelf Life: 36 months (3 years) from manufacturing date

About MAC Batch Codes
MAC encodes production dates inside the batch code rather than printing an expiry date on the carton. The MAC format used here is batch/factory + month + year (e.g., c79, c11), which is what lets the decoder return a manufacturing date rather than a vague guess.
Two codes on the same product are not a problem. The outer carton and the inner container are frequently produced in different runs, and the later of the two is the one that governs the freshness of what is inside.
If the packaging also carries a printed expiry date, trust the packaging. The batch code tells you when the product was made; the printed date tells you when it should be used up.
Where to Find Your MAC Batch Code
On MAC products the batch code sits close to the base, the seal, or the barcode. Work through these areas:
Work down this list and you will find it:
- Makeup: on the underside of a compact or the base label of a lipstick
- Packaging: on the base or underside of the container
- Carton: on the bottom panel, or next to the barcode
- Label: printed near the LOT or production code on the back label
Under bright light the code is easier to read than it looks at arm's length. A phone flashlight and a macro photo will resolve characters that are invisible in a dim room.
Most Looked-Up MAC Ranges
These are the MAC ranges that come up most often in batch code lookups:
- Makeup: Ruby Woo, Velvet Teddy, Mehr, Powder Kiss, Lipglass
- Product lines: Studio Fix Fluid, Studio Radiance, Pro Longwear, Prep + Prime
- Makeup ranges: eyeshadow palettes, blushes, Mineralize Skinfinish, seasonal collaborations
Codes from different MAC ranges do not share one layout, so it is worth checking each product individually rather than assuming the format from the last one you decoded.
Practical Advice for MAC Codes
Read the code before you open the product. Once the seal is broken the print can wear off, and a photograph is worth more than a guess later.
Check the bottom of the container before anything else. The batch code is more often there than on the carton, and it is the code that governs the contents.
