Certificate of Authenticity vs. Authenticity Card: What’s the Difference?

When buying a pre-owned designer bag, you may see the terms Certificate of Authenticity (COA) and authenticity card. They sound similar, but they are not the same thing.

Here’s the simple difference:

Authenticity Card: An original card supplied with certain designer items.

Certificate of Authenticity (COA): Documentation issued after an item has been evaluated by an authentication provider.

What Is an Authenticity Card?

An authenticity card is an original inclusion from the designer.

Chanel is one of the best-known examples. Many older Chanel bags originally came with a numbered authenticity card associated with the bag's identification system.

For collectors, having the original card can make a vintage or discontinued piece more complete and desirable.

However, an authenticity card alone does not prove a bag is authentic.

Cards, receipts, boxes and dust bags should be considered original accessories or supporting documentation, not substitutes for authenticating the item itself.

What Is a Certificate of Authenticity?

A Certificate of Authenticity, commonly called a COA, is typically issued after a luxury item has been evaluated by an authentication provider.

Depending on the item, authentication may examine materials, construction, stitching, hardware, engravings, logos, serial or date markings and other brand-specific details.

The easiest way to remember it:

Authenticity card = original designer inclusion

COA = documentation of an authentication assessment

Can a Designer Bag Be Authentic Without Its Authenticity Card?

Yes.

Vintage and pre-owned bags may have changed owners several times, and original cards, receipts, boxes and dust bags are often lost or discarded over the years.

A missing authenticity card does not automatically mean a bag is counterfeit.

The opposite is also true. Having an authenticity card, receipt or designer box does not automatically prove that the item accompanying it is authentic.

What About Chanel?

Many older Chanel bags used a serial sticker and corresponding numbered authenticity card. Chanel later moved away from this traditional system on newer pieces.

This means whether you should expect an authenticity card depends on the age and production era of the bag.

An original matching card can be a desirable bonus for collectors, but it should never be the only factor used to determine authenticity.

Buying Pre-Owned Luxury With Confidence

When buying a pre-owned designer piece, look beyond the card. Consider the actual item, condition, seller transparency and authentication.

At Curated Finds Co., all designer bags and wallets include a complimentary Certificate of Authenticity from a trusted third-party authentication expert. Certificates are also available for purchase on other eligible designer items, giving you added confidence when shopping pre-owned luxury.

Original accessories such as authenticity cards, boxes, dust bags and receipts are listed separately, so you know exactly what is included with your purchase.

The Bottom Line

An authenticity card is an original designer inclusion. A Certificate of Authenticity documents an authentication assessment.

A designer bag can be authentic without its original card, and a card alone does not prove authenticity.

When buying pre-owned luxury, authenticate the item, not the packaging.
