The houses will not help, and it is worth knowing why
People often assume the first call is to the maker. It is not: the major houses do not authenticate handbags for members of the public, do not issue certificates of authenticity, and generally will not comment on whether a bag is genuine. Some will decline to repair a bag they believe is counterfeit, which is an answer of a kind but not one you can use.
The reasons are legal and commercial rather than obstructive. A written opinion creates liability, invites litigation from both directions, and creates a document that counterfeiters would immediately forge.
Which means authentication is a third-party industry, and it is a real one — a small number of established services with reputations, staffed by people who have handled thousands of examples of each model.
Four routes, and what each settles
Note that the first two are free and the first one is the one that decides whether you spend anything at all.
| Route | What it answers | What it cannot | Typical cost |
|---|---|---|---|
| A free identifier app | House, silhouette, size and an indicative resale range | Authenticity — the visual features are the ones counterfeiters perfect | Nothing |
| The construction checks, yourself | Most obvious and mid-tier fakes, via hardware weight, stitching and pattern alignment | The best counterfeits, which get construction closer | Nothing |
| A third-party authentication service | A written opinion, usually from photographs, that platforms and buyers accept | A guarantee — it is an opinion, and services disclaim accordingly | Roughly $15 – 75; more for a physical inspection |
| A resale platform's own authentication | Whether they will list and stand behind the item | Anything about a bag you are not selling through them | Included in their commission |
The house itself does not appear in this table because it does not offer the service. Any 'brand certificate of authenticity' for a handbag should be treated as a document a counterfeiter produced.
The free checks, in the order a specialist runs them
Most people start with the logo, the heat stamp and the date code, which is starting with the three things counterfeiters have had forty years to perfect. The order below is the order that actually discriminates, and it costs nothing.
The reasoning is economic. Counterfeiters optimise for what a photograph and a glance assess, and they economise on what costs money to get right: solid plated hardware rather than hollow castings, a consistent stitch count on panels that should match, a monogram that lines up across a seam because the maker wasted leather to make it line up, and lining in the right material and colour.
- Pick it up. Hollow-cast hardware feels wrong even to an untrained hand.
- Count the stitches on two panels that should match. Inconsistency means nobody was counting.
- Follow the pattern across every seam. A copy saves leather by letting it jump.
- Open it and compare the lining against the house's own product photography for that model and year. Wrong material is common; wrong colour is conclusive.
- Smell it. Genuine leather smells of leather, not of glue or plastic.
- Only now look at the heat stamp, the date code and the engraving.
The threshold, with the arithmetic
A written authentication at $15 to $75 is trivial against a four-figure bag and is what a resale platform or a private buyer will ask you for, so on anything at that level it is simply a cost of doing business — and cheap insurance against a chargeback or a failed sale.
On a bag with a likely resale value of a couple of hundred, the calculation is tighter but often still favourable if you are selling to a stranger, because the alternative is a dispute.
Below roughly a hundred and fifty, it stops making sense: the fee is a large fraction of the value, and the free construction checks plus an honest description handle it. This is precisely what a free identification is for — not to authenticate the bag, but to tell you which of these three situations you are in before you spend anything.
The point of the free step is not to answer the question. It is to tell you whether the question is worth paying to answer.
Choosing a service, and reading its answer honestly
Prefer services with a long trading history, named authenticators, a clear statement of what their opinion does and does not cover, and a specialism in the house you are asking about. A service that authenticates every brand equally well is claiming something implausible.
Send what they ask for and more: the front square-on, the interior heat stamp close and in focus, hardware including engraved zip pulls and feet, the base and corners, the lining and pocket construction, any date code or serial, and the dust bag and receipt if they exist.
And read the result for what it is. Every reputable service issues an opinion, not a guarantee, and says so. An opinion from someone who has handled a thousand examples of that model is extremely valuable and it is still an opinion — which is the same standing as an expert's view in every other category the house reads.
