Louis Vuitton Batch Code Checker: Is Your Perfume Authentic?

Louis Vuitton's Les Parfums collection is Scento's single-largest revenue brand — and one of the most opaque about its codes. LV publishes no decoder and no customer-service page that explains the code format. The codes themselves, though, follow the same LVMH layout as Dior's, and independent decoders and owner reports line up on how to read them. We have 1,216 authenticated LV bottles in our intake database since 2021. The decoder reads the year and month from the code and labels the result MEDIUM confidence — below the HIGH we give houses with fully documented schemes — and the methodology page explains exactly what that label means.

If you need a confirmed production date for an LV bottle, the only authoritative source is LV customer service directly. They will provide a date over email if you submit the bottle code along with the original receipt; turnaround is usually 14–21 days.

How the LV code works

Louis Vuitton makes Les Parfums in-house, in the Maison's facilities in Grasse, France, under LVMH — and the bottles carry the same four-character code as Dior, LVMH's other big fragrance house:

• Character 1 — year. The last digit of the production year. LV has made perfume only since 2016, so 1 is 2021, 3 is 2023 and 8 is 2018.
• Character 2 — month. A letter from A to M, skipping I: A = January, B = February, C = March, D = April, E = May, F = June, G = July, H = August, J = September, K = October, L = November, M = December.
• Characters 3–4 — lot. Two characters identifying the batch; not part of the date. Sample vials and some cartons add one or two more (1L01A1).

So 1H02 is August 2021: year digit 1, month letter H, lot 02. Because the year is a single digit, a code from 2016 or 2017 shares its digit with 2026 or 2027. The decoder returns the most recent date that is not in the future, so a 2016 bottle can read as 2026 once that month has passed; the carton and the purchase history settle it.

A code that starts with letters (such as LP24DA17), a month letter after M, or a letter I or O in the month position does not follow this layout, and the decoder answers it with "We couldn't read that code".

Worked examples

• 1H02 decodes to August 2021. Year digit 1 (2021), month letter H (August), lot 02 — an Imagination bottle bought in its launch year.
• 3F03 decodes to June 2023. Year digit 3 (2023), month letter F (June), lot 03; an owner of the same batch dated it "06/23".
• 4D01 decodes to April 2024. Year digit 4 (2024), month letter D (April), lot 01.

Where the code lives on an LV bottle

Three placements, and the rim placement is the most diagnostic:

1. Underside rim laser etch — 4 to 5 millimetres above the bottom edge of the bottle, on the rim itself rather than on the flat centre. This rim placement has been LV's standard since 2018; pre-2018 production used a centre placement, which was less consistent. Counterfeits frequently get the placement wrong, putting the etch in the centre when the bottle is recent enough that it should be on the rim.
2. Inner foil flap — open the carton, lift the inner cardboard insert, and look for a foil-stamped code on the hidden side of the bottom flap. The foil should be a deep gold (matches the LV monogram colour); silver or bronze foil is a counterfeit flag.
3. Travel-case insert (Les Extraits only) — Imagination Parfum, Spell On You Extrait, and Symphony all ship in a leather travel case with an internal cardboard insert that carries an additional code. This is a triple-reference point on the higher-end SKUs.

The 12-point intake check

Because a date alone never proves a bottle genuine, the physical authentication is doing the heavy lifting. Our 12-point intake check covers:

• Calibrated bottle weight against a reference for each SKU. LV uses a specific high-density glass; counterfeits run light by 20–30g.
• Atomiser pull-test — the genuine atomiser collar is firmly seated and should not rotate; counterfeits often have loose collars that twist.
• Cap finish under angled light. Mirror-polished anodised aluminium has a specific wet-look reflectivity; brushed or matte finishes are flags.
• Leather travel case stitching pattern (Les Extraits). Hand-finished stitching has slight irregularity; machine-perfect even spacing is a flag.
• Carton embossing on the inner flap. The LV monogram should be deeply embossed on the foil; flat or shallow embossing is a flag.
• Foil sticker tone (gold, not silver or bronze).
• Box paper grain. Genuine LV cartons use a specific cream paper with a subtle linen grain; counterfeits tend to use smoother stock.
• Ribbon weight (giftable bottles only). Genuine LV ribbons are heavy silk; counterfeits use polyester or thinner silk substitutes.
• Cellophane wrap pattern.
• Code etch depth and position (rim, not centre).
• Code typography — sans-serif, sharp character edges.
• Juice colour and viscosity against calibrated reference for each SKU.

A flacon must pass all twelve to enter our inventory. We've rejected 79 LV bottles since 2021, a roughly 6.1% rejection rate.

Counterfeit stories

The four counterfeit-rejection stories in this page's frontmatter give a representative sense of what we see in intake. The summary pattern: the juice is often a competent imitation, the bottle shape is usually close, but one or two physical signals consistently fail. Imagination's etch position. Pacific Chill's leather stitching. Ombre Nomade's cap finish. Spell On You's inner-flap embossing. Counterfeit operators improve on each batch — the imitations we intercepted in 2024 are noticeably better than the 2022 batches — but the physical authentication keeps catching them.

What to do if the exact date matters

1. Source from authenticated stock. If you intend to wear the bottle and the date matters for freshness, the simplest path is to source from an intake-verified retailer. Our LV collection carries decants of Imagination, Pacific Chill, Ombre Nomade, Attrape-Rêves, Spell On You, and the rest of the active line, all authenticated using the 12-point check above.
2. Contact LV customer service with the code and your original receipt. They will confirm the production date over email; expect a 14–21 day response window.
3. Read the methodology page for the full explanation of how the decoder reads LV codes and what the MEDIUM label means.

A final note on LV's pricing context

Louis Vuitton fragrances retail at €270 for a 100 ml bottle and up to €450+ for the Les Extraits line. The price gap between an authentic bottle and a competent counterfeit is roughly €200, which is the economic engine driving the LV counterfeit market. The pure-decant alternative — an 8 ml authenticated atomiser at a fraction of the bottle price, sourced through Scento's intake-checked supply chain — is the safest way to wear LV without engaging the secondary market at all.
