Calvin Klein batch code: production date & authenticity check

Where to find your Calvin Klein batch code

On real Calvin Klein packaging (made by Coty Inc.) — green is the code, red is not (the barcode, article number or open-jar symbol):

✓ The batch code is 0275

✗ Not the code: 75002, TN25 4AQ, 36M (open-jar / PAO), 3614226905185 (barcode)

✓ The batch code is 8106

✗ Not the code: 3614226702982 (barcode), 36M (open-jar / PAO)

✓ The batch code is E7 1477304661

✗ Not the code: 3414202000572 (barcode), 36M (open-jar / PAO)

On a Calvin Klein bottle the batch code is etched or printed on the glass underneath, or on a small sticker on the base; on the box it is on the bottom flap or the back — near the barcode but separate from it — a short code of 4 to 10 letters and numbers. On a genuine set the code on the box and the code on the bottle are the same. Decants and testers usually carry only the bottle code.

• 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 Calvin Klein batch codes

Calvin Klein codes encode a year digit plus the day of the year. The brand is owned by Coty / Calvin Klein licensing.

Real documented examples: code → manufacture 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.

We've read 280 Calvin Klein batch codes so far, the newest was made August 2026, and the typical Calvin Klein product people check here is about 33 months old.

Can the batch code tell me if my Calvin Klein is authentic? Not on its own. A code that decodes to a sensible date, printed the same on the box and on the bottle, is a good sign, but counterfeiters copy real codes from genuine packs, so a valid code cannot prove a Calvin Klein product is authentic. Buy from Calvin Klein or an authorised retailer, and compare the packaging, print quality, sprayer and cap fit with one you know is genuine.

Does Calvin Klein expire?

Yes — like all cosmetics and fragrances, Calvin Klein 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.

How long Calvin Klein products last

Unopened: general cosmetics guidance. Opened: general guidance by product type. A date or open-jar symbol on your pack always wins.
