Chanel Season Codes Explained: 18A, 19K, 20C and More
Share
Quick answer: A Chanel season code is the two-character stamp — like 18A, 19K, or 20C — that identifies which collection a piece is from. The two digits are the year and the letter is the season: P = Spring/Summer (Act 1), S = Summer, A = Métiers d’Art / Pre-Fall, B = Fall/Winter (Act 1), K = Fall/Winter (Act 2), C = Cruise/Resort, and V = Classic year-round line. So 20C = the 2020 Cruise collection, 18A = 2018 Métiers d’Art, and 19K = a 2019 Fall/Winter Act 2 piece. The most common mistake is reading “A” as Autumn — it actually marks the Métiers d’Art collection. Chanel doesn’t publish an official key, but this is the standard convention used across the pre-owned market (Vestiaire, Fashionphile, Yoogi’s Closet) to date and value preloved Chanel.
If you have browsed preloved Chanel, you have seen pieces labelled 18A, 19K, or 20C and probably wondered what the codes mean. These are Chanel's season codes, a shorthand that tells you exactly which collection a piece comes from and, with it, the year and runway behind it. Learn to read them and you can date any Chanel item at a glance, judge its rarity, and shop far more confidently.
This guide breaks down every letter, decodes the most common examples, and clears up the single biggest misconception (no, "A" does not mean Autumn).
What a Chanel season code actually is
Chanel releases six collections every year, and the pre-owned market labels each one with a two-character code: the two-digit year followed by a letter for the collection. So "20C" means a piece from Chanel's 2020 Cruise collection.
It is worth separating two things that often get confused:
- The season/collection code (e.g. 19K) tells you which collection a piece belongs to. It is how collectors and resellers describe a bag or garment.
- The serial number (the sticker or, on bags from 2021, the embedded microchip) is about authenticity and production dating, not the runway collection.
One important caveat: Chanel does not publish an official public key for these letters. The system below is the convention used consistently across the pre-owned market, Fashionphile, Vestiaire, Yoogi's Closet, and the collector community, so it is the practical standard for buying and selling preloved.
The Chanel season-code letter key
| Letter | Collection | Typically released |
|---|---|---|
| C | Cruise / Resort (Croisière) | November–January (of the prior year) |
| P | Spring, Spring/Summer Act 1 (Printemps) | January–March |
| S | Summer, Spring/Summer Act 2 | March–June |
| A | Métiers d'Art / Pre-Fall | May–September |
| B | Fall/Winter Act 1 | June–October |
| K | Fall/Winter Act 2 | August–November |
| V | Classic / Continuous line (year-round staples) | Ongoing |
| M | Coco Beach (resort / swim capsule) | Warm-season capsule |
| N | Coco Neige (winter / ski capsule) | Cold-season capsule |
The six seasonal collections roughly follow a new drop every two months, which is why the codes cycle C → P → S → A → B → K through the year.
Beyond these, Chanel runs two seasonal capsule lines with their own letters: M for Coco Beach (resort and swim) and N for Coco Neige (winter and ski). A 25N piece, for instance, comes from the 2025/26 Coco Neige capsule.
How to read a code: worked examples
Once you know the key, decoding is simple, read the number as the year, then the letter as the collection:
- 18A = 2018 Métiers d'Art collection
- 19K = 2019 Fall/Winter Act 2 collection
- 20C = 2020 Cruise collection
- 22P = 2022 Spring (Spring/Summer Act 1)
- 23S = 2023 Summer (Spring/Summer Act 2)
The big misconception: "A" is not "Autumn"
This trips up almost everyone. Because "A" looks like it should stand for Autumn, buyers assume an "A" code is a fall collection. It is not, A is the Métiers d'Art / Pre-Fall collection. Chanel's actual fall collections carry the letters B (Act 1) and K (Act 2). Similarly, V is not a season at all: it marks the timeless, continuously produced Classic line, so a "V" piece can't be pinned to one runway.
Why season codes matter when you buy preloved
For a one-of-a-kind pre-owned market, the code is useful:
- Dating: it instantly tells you how old a piece is, independent of condition.
- Provenance: it ties the item to a specific runway, which matters for collectors chasing a particular season's colourway, tweed, or hardware.
- Rarity and value: certain collections (notably the elaborate Métiers d'Art "A" releases) are more sought-after, which supports resale value.
- Matching: if you are completing a look, the code helps you find pieces from the same collection.
This is why we include the season code in our product titles wherever it is known, it is one of the fastest ways to tell our pieces apart. You can see it in action across our Chanel collection and the latest new arrivals.
Where to find the code on a piece
On handbags and small leather goods, the collection is usually identified via the authenticity card and serial sticker era (or the microchip on 2021-onward bags). On ready-to-wear, look at the white fabric care/size tag sewn into the garment: it carries a style code whose leading letter follows the same seasonal system. If a seller can't tell you the season of a piece, that is a fair question to ask, a knowledgeable reseller will know it.
Frequently asked questions
What does 18A mean on a Chanel bag?
18A means the piece is from Chanel's 2018 Métiers d'Art collection. The "18" is the year and the "A" is the collection code, which, despite appearances, stands for Métiers d'Art / Pre-Fall, not Autumn.
Does the letter "A" in a Chanel code mean Autumn?
No. This is the most common misconception. "A" denotes the Métiers d'Art / Pre-Fall collection. Chanel's fall collections use the letters B (Fall/Winter Act 1) and K (Fall/Winter Act 2).
What does 19K mean?
19K is the 2019 Fall/Winter Act 2 collection. "K" is always the second act of a year's fall/winter season.
What is the difference between a season code and a serial number?
The season code (like 20C) identifies which collection a piece is from. The serial number, a sticker on older bags or an embedded microchip on bags from 2021, relates to authenticity and production dating, not the runway collection.
Are Chanel season codes official?
Chanel does not publish a public letter key, but the system described here is the convention used consistently across the pre-owned market and collector community, so it is the practical standard for dating and describing preloved pieces.
Now that you can read the codes, put them to use. Browse our Chanel collection, each piece is dated and described by its season, so you always know exactly which collection you are buying into.
