Chanel Serial Numbers and Microchips Explained

Fashionphile, a resale specialist, says that since the mid-1980s Chanel handbags and small leather goods have included a small sticker with a serial code inside, and that the same code appeared on an accompanying authenticity card.

According to Fashionphile, codes from 1986 to 2005 have seven digits and later codes have eight, and a subtle hologram was added to the sticker in the 2000s. It also notes that stickers can curl, come off, or turn yellowish or purple with age, so a worn sticker on an older bag is not a warning sign by itself.

Madison Avenue Couture, a reseller, reported in October 2021 that eight-digit codes starting with 31 or 32 may be among the last bags made with stickers and cards.

The series is the first digit of a seven-digit code or the first two digits of an eight-digit code. The chart below follows the reseller Rebag's published reading of each series, with the last two series added from Madison Avenue Couture's 2021 report.

Ranges overlap because production did not follow calendar years, and charts from other resellers differ by a year here and there. Read a series as an approximate period, not an exact date.

In the sticker era, the authenticity card carried the same number as the sticker in the bag. A match shows that the card and the sticker go together. It does not show that either belongs to a genuine bag, because cards and stickers can be copied, and genuine ones can be separated from the bag they came with.

Testimony in Chanel's lawsuit against the reseller What Goes Around Comes Around, reported by PurseBop, described a 2012 theft of about 30,000 authenticity cards with serial numbers from an Italian factory that produced Chanel handbags. The Fashion Law reported that Chanel linked bags in the case to serial numbers it had voided before use, through records from its internal tracking system, and that counterfeiters had used stolen authenticity cards. A US jury found for Chanel in February 2024.

A genuine-looking card with a valid-looking number is therefore not proof on its own.

Madison Avenue Couture reported that from April 2021, starting with the 21A collection, Chanel replaced the serial sticker and the authenticity card with a small metal plate attached inside the bag. In its description the plate is about 1.2 inches wide, matches the color of the bag's hardware, shows the CC logo above an 8-character code, and has an NFC microchip embedded in it.

Fashionphile says the plate codes start with a letter followed by a mix of numbers and letters, are no longer in sequence like the old stickers, and do not indicate a production year. It adds that small leather goods received a new sticker in the same format, and that retail tags are now the only way to know an item's season.

Madison Avenue Couture also reported that the chip's data can only be read with proprietary devices used by Chanel staff in its boutiques. A phone scan is therefore not a Chanel verification, whatever it shows.

A serial number places a bag in an approximate period and gives you something to compare: whether the sticker or plate, the number of digits and the series fit the model, its hardware and the season the seller claims. A bag sold as a 2019 Classic Flap with a seven-digit sticker, or as a 2023 bag with an old numbered sticker instead of a plate, needs an explanation.

It cannot prove the bag is genuine. Chanel says it cannot give the public detailed information on how to identify genuine products, and it recommends buying only from Chanel boutiques or retailers it authorizes. It also says there are no authorized sellers of its leather goods, fashion items and watches on the internet. There is no public Chanel database where a buyer can enter a number.

Missing pieces need context, not panic. Fashionphile notes that older bags without their card or sticker can still be authentic and can still be authenticated by experts.

Read the code alongside the rest of the evidence: the exact model and size, quilting and panel alignment, leather or fabric, chain and turn-lock construction, interior stamps, and the seller's history. Vereev weighs these together in its review and is independent of Chanel.
