How do I check a Xerjoff batch code?

Find the code on the bottle base and the box — they must match — then run it through a batch-code calculator (CheckFresh / CheckCosmetic) to confirm it decodes to a plausible recent production date.

Why is my Xerjoff so light / why does the spray spit?

Genuine Xerjoff uses thick, heavy glass and a fine atomizer. A light bottle, a wobbly pump or a spitting/short-tube sprayer often indicates a refilled or counterfeit bottle.

Where do most fake Xerjoff bottles come from?

Grey-market, 'tester', and deeply-discounted marketplace listings. Buying from authorized retailers is the most reliable way to avoid refills and counterfeits.

Read the code

The Xerjoff batch code (production date)

Batch code (production date)

Format: A batch code is laser-etched or stamped on the BOTTOM of the bottle AND printed on the box — and the two MUST match. The code decodes to a production date via a batch-code calculator (e.g. CheckFresh / CheckCosmetic). Xerjoff bottles are heavy, faceted glass with a weighty cap.

Where to find it: Bottom of the bottle and on the box base/flap.

How to verify (honest): There's no brand 'authenticity serial', but the batch code is a real, checkable signal: if the bottle code and box code don't match, or the code doesn't decode to a plausible recent date, treat it as suspect. Buy from Xerjoff's authorized retailers — grey-market and 'tester' listings are where most fakes and refills live.

Don't stop at the code

A serial alone never proves authenticity

A correct-looking code on a poorly-made item still means fake — and fakers copy valid codes. Cross-check the code against the physical tells below.

What to check	Genuine	Fake
Batch code match	Identical batch code on the bottle base and the box, decoding to a sensible production date.	Bottle and box codes differ, code missing, or it decodes to an impossible/very old date.
Glass & weight	Thick, heavy, well-faceted glass with a substantial cap; precise, centered labeling.	Lighter, thinner glass; a flimsy cap; crooked or low-resolution labels.
Cellophane & seal	Factory cellophane is tight with a clean, straight seam and no overlap flaps; box printing is sharp.	Loose, hand-wrapped cellophane, double seams, fuzzy printing, or a re-glued box.
Atomizer & spray	Fine, even mist on the first pump; pump seats flush; tube reaches the bottle base.	Spitting/uneven spray, a wobbly pump, or a short tube — common on refilled fakes.
Juice color & smell	Color matches the known reference for that fragrance; scent opens true with correct longevity.	Off color (too dark/pale), a sharp alcohol blast that fades in minutes — a sign of diluted/fake juice.
