Assess the transaction before assessing the object. Confirm who is selling, how long the seller has operated, where the item is located, how payment is protected, what the return window is and who pays for return shipping. A seller who refuses reasonable questions, pressures you to pay off-platform or will not document condition adds risk.
Begin with the seller and the terms
Assess the transaction before assessing the object. Confirm who is selling, how long the seller has operated, where the item is located, how payment is protected, what the return window is and who pays for return shipping. A seller who refuses reasonable questions, pressures you to pay off-platform or will not document condition adds risk.
For a marketplace purchase, read its current authenticity guarantee and dispute terms yourself. Note whether authentication occurs before or after delivery, what happens if an item is disputed, the deadline for a claim and whether an external opinion is accepted. Policies vary and can change.
Identify the exact reference and era
Authentication has to be model-specific. Find the closest official product description, a museum record or a reliable reference for the same model, size, approximate year and material. Many houses change stamps, hardware, stitching, lining, codes and construction over time; the absence of one feature is not universal proof of a counterfeit.
Ask the seller for clear, unfiltered photographs in natural light: front, back, base, both sides, corners, handles, strap attachments, zipper teeth, hardware engravings, interior, labels and any code or date marking. Compare the overall construction and proportions, not just the logo.
Treat codes and paperwork as supporting evidence
A serial number, date code, authenticity card, dust bag, receipt or box can be copied, swapped or paired with another item. Older genuine bags may not follow today’s systems; newer items may use different identification methods. A plausible code does not establish that the bag itself is genuine.
Request provenance information that can be checked and matches the item: when and where it was purchased, service or repair records, and any original invoice with personal information redacted. Paperwork can support a consistent story but should not replace an examination of the bag.
Use independent expertise when the stakes justify it
For an expensive or hard-to-assess piece, use an established authenticator with experience in that specific house, model and era. Ask what evidence the service examines, whether it accepts the model, what its limitations are, and whether the opinion is written and tied to the exact item. A photo-only service may not be able to inspect weight, smell, hidden construction or material behaviour.
When uncertainty remains, walk away. Authenticity is not a bargain if you cannot verify what you are buying. This guide is educational, not an authentication service, and cannot certify an individual handbag from a seller description.
Frequently asked questions
Can a serial number prove a luxury bag is authentic?
No. Codes and serials are only one piece of evidence, can be copied or mismatched, and vary across brands, models and years. They must be assessed alongside the exact bag and its provenance.
Can I authenticate a bag from photos?
Photos can help identify questions and visible inconsistencies, but they do not expose every material, construction or provenance detail. For a high-value purchase, use a qualified specialist and a seller with meaningful return protection.
Does an authenticity card or receipt prove the bag is genuine?
No. Documents can be separated from the item or copied. They may support a consistent provenance story, but the bag itself needs independent assessment.
