Louboutin box label checker, does the box match the shoes

The reference, such as 3130694 BK01, is seven digits that identify the style and four characters that identify the colour. BK01 is black on every listing we checked. The same style can carry different seven digit numbers in different materials: the So Kate 120 appears as 3130694 in patent, 3130693 in kid and 3130692 in suede. Every pair of the same style and colour has the same reference.

No. Christian Louboutin does not put a serial number or a production date on its shoes or its boxes, and no independent source we found describes one. The reference on the box is a style and colour code shared by every matching pair. Anyone offering to date a pair of Louboutins from a number is inventing the answer.

It is the heel height in millimetres. A So Kate 120 has a 120 mm heel and a Loubigirl 85 has an 85 mm heel. Measure at the back of the shoe, straight up from the floor to where the heel meets the upper. A few millimetres either way is normal, depending on how you measure and the size of the pair, but a label that says 120 on a heel that measures nearer 100 does not describe the shoes in the box.

Yes. Louboutin labels its boxes with the EU size, and the same size is stamped on the sole, including half sizes such as 37.5. A box marked 38 holding shoes stamped 37 came with another pair. That is often an innocent swap from a resale or an exchange, but it means the box tells you nothing about these shoes.

No. Real boxes are sold on their own and put with fake shoes, and counterfeit boxes are printed with real references copied from listings. A matching label tells you the box and the shoes describe the same product, which is useful, but the shoes themselves are what an authenticator examines: the shape of the last and toe, the heel, the sole and its finish, and the stitching.

Almost always in Italy, and the sole says so. Some espadrilles are made in Spain. A pair whose sole or label names another country is worth a closer look, although we cannot rule out a line we have not seen, so treat it as a question to ask rather than a verdict.

First check that you have typed the reference and not the barcode, which is a longer number on the same label, or the style name. Then check for look alike characters, an O for a 0 or an I for a 1 in the colour code. Older boxes may be laid out differently from the current format, and we have not been able to document them, so an unusual layout on an old box is not on its own a reason to doubt it.

Louboutin has no serial number to check, which is why this page checks the box label instead, free and with no signup. Type the reference and it tells you whether the layout is the one Louboutin uses. Add the reference from the receipt or the listing and it tells you whether the box belongs to that purchase. What you get back is a consistency check, not a verdict on whether the shoes are genuine.
