My Louis Vuitton has no date code — is it fake?

Not necessarily. LV stopped using date codes in 2021 and switched to a hidden RFID chip. A recent authentic bag legitimately has no date code. For older bags, the absence of a date code where one is expected is a concern.

Can a Louis Vuitton date code prove the bag is real?

No. The date code only encodes the factory and the production week/year. A faker can copy a valid-looking code, and a valid code on a poorly-made bag still means fake. Use it as one data point alongside stitching, the heat stamp and hardware.

Where is the date code on a Louis Vuitton bag?

It varies by model — on an interior leather tab, inside a pocket, or stamped into a seam. The format is two letters followed by four digits.

Read the code

The Louis Vuitton date code (not a serial number)

Date code (not a serial number)

Format: LV bags made before 2021 carry a DATE code, not a serial: two letters + four digits stamped on a leather tab or directly inside. The letters are the factory (e.g. SD/FL = USA, AR/RI/SR = France, CA/LO/MB = Spain). From 2007 on, digits 1 & 3 are the week, digits 2 & 4 are the year — so 'SD2168' = week 28 of 2016, made in the USA.

Where to find it: On an interior leather tab, inside a pocket, or stamped into a seam — location varies by model.

How to verify (honest): Critical 2021 change: Louis Vuitton REMOVED date codes and switched to an embedded RFID microchip. So a brand-new authentic bag has NO date code — its absence on a recent bag is normal, not proof of a fake. There is also no public LV date-code lookup; the code only encodes factory and date, never authenticity. Treat any 'LV authentication serial checker' as fake.

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
Monogram canvas	Pattern is symmetrical and the LV/flower motifs line up logically across panels; on symmetric bags the pattern mirrors. Canvas is slightly textured and stiff.	Motifs cut awkwardly at seams, off-center, or the canvas is flat, plasticky and overly shiny.
Stitching	Even, regular, slightly slanted, in a mustard-yellow tonal thread; consistent stitch count on tabs (e.g. 5 stitches across the handle tabs of many models).	Uneven spacing, wrong color thread, loose ends, or a different stitch count from the known model spec.
Heat stamp	'LOUIS VUITTON ®, made in France/USA/Spain' is crisp and evenly spaced. The O's are perfectly round, the L's foot is short, and the two T's are close together.	Thin, faded, or uneven lettering; O's that look oval; spacing that drifts across the line.
Hardware	Heavy, warm-toned brass; zippers and lock pulls are engraved 'LOUIS VUITTON', not printed. The lock and keys are solid.	Light, pale, or silvery hardware; printed (not engraved) logos; a hollow lock.
Edges & glazing	Painted edges ('glazing') are smooth, even and usually a warm red/tan; vachetta leather is untreated and pale, darkening to honey patina with age.	Sloppy, cracked or wrong-colored edge paint; vachetta that's pre-dyed dark to fake a patina.
