Wildberries Barcodes and Labels for FBO and FBS: A Seller's Guide

Wildberries barcodes and labels are where many first supplies from abroad go wrong. The goods are fine, the card is ready, but the box arrives at the warehouse with an unscannable sticker or a label missing a required line, and the supply is refused or billed with a penalty. This guide explains which barcodes Wildberries works with, how labelling differs between FBO and FBS, what text must be on the product label, and how to print everything correctly. Wildberries updates its warehouse rules regularly, so confirm the specifics in the seller portal's instructions before every large shipment.

Which barcode Wildberries uses

Every product variant on Wildberries, meaning each article in each size, needs its own unique barcode. You have two options.

**Your own EAN-13.** If your products already carry GS1 barcodes from the factory, you can register those numbers on the card.
**A Wildberries-generated barcode.** In the seller cabinet you can generate barcodes for each size. This is the most common choice for cross-border sellers, since it avoids licensing GS1 numbers and guarantees uniqueness inside the marketplace.

The number itself is what matters to the warehouse scanner. The printed symbology is typically CODE-128, a compact linear format that encodes digits reliably at small sizes and is what most thermal label software and the WBGen barcode generator produce. One rule has no exceptions: one barcode, one variant. Reusing a code across colours or sizes leads to mixed stock and unhappy customers.

FBO: labelling a supply to the Wildberries warehouse

Under FBO you ship goods to a Wildberries fulfilment centre, which then stores and dispatches them. Three layers of labelling are involved.

Product label

Each unit gets a label with the product barcode and the required text (see the next section). Place it on the outer packaging where a scanner can reach it without opening the item, not across a seam or a curved corner.

Box label

When you create the supply in the cabinet, Wildberries generates a barcode for every box. Print it and stick it on a long side of the box. A box should contain products from one supply only; mixing supplies is a common cause of rejection.

Pallet label

For pallet deliveries a pallet barcode is generated as well. Stack boxes so the labels face outward and wrap the pallet so that nothing overhangs the base.

Before the truck leaves, scan one label from each layer with a phone app. If it reads correctly on your side, it will read at the gate.

FBS: labelling individual orders

Under FBS the goods stay in your or your partner's warehouse in Russia. When an order comes in, you pack it and attach an order sticker generated in the cabinet. That sticker, usually printed at 58×40 mm, carries the order barcode the sorting centre scans. The product barcode must still be present on the item, because returns and quality checks rely on it. The two stickers should not overlap, and the order sticker goes on the outside of the shipping packaging. Mind the assembly deadline: late orders hurt your seller rating.

What must be on the product label

Russian consumer-protection rules and the marketplace itself expect certain information on or in the packaging, in Russian. Requirements vary by category, so check the current list, but a typical label for a consumer product includes:

Product name in Russian (for example, "Беспроводные наушники")
Brand and seller article (vendor code)
Colour and size, with Russian sizes for apparel
Material or composition
Manufacturer or importer name and address
Country of origin
Date of manufacture or batch, where applicable
The EAC conformity mark, if your category falls under EAEU technical regulations
The barcode itself with its digits printed below

For categories covered by mandatory digital marking, the marking code is an additional sticker and must be applied before import. Do not run the label through a free translation tool and print it; a wrong grammatical case or a transliterated size scale is exactly the kind of detail that gets flagged during warehouse checks and in reviews.

Printing: format, materials, common errors

**Size.** 58×40 mm is the de facto standard for both product labels and order stickers on Wildberries. Smaller formats exist for tiny items, but keep the barcode at least about 25 mm wide.
**Printer.** A direct-thermal label printer is cheaper per label and avoids smearing. If you print on A4 with a laser printer, cut precisely and use strong adhesive.
**Quiet zones.** Leave blank margins on both sides of the barcode; a border touching the bars breaks the scan.
**Resolution.** Print at the printer's native resolution without scaling. Scaled images blur the bars.
**Durability.** For cold or humid storage use synthetic labels; paper peels.
**Placement.** One label per unit, flat, not on a fold, not under shrink wrap.

Most refused supplies come from stretched barcodes, quantities in the box that do not match the cabinet, and missing product labels inside the box. A five-minute scan test eliminates the first two.

Generating labels for free

You do not need paid software to produce compliant labels. The free CODE-128 barcode and label generator from WBGen takes your barcode numbers (your own EAN or the Wildberries-generated ones), adds the product name, article, size and colour in Russian, and outputs a print-ready file in the 58×40 mm format. It is handy for cross-border teams that prepare labels at the factory in China before shipping, so goods arrive ready for the warehouse.

Labels are the last step before stock goes live; the card is what sells it once it does. If you are preparing your first supply, read our product launch checklist for Russian marketplaces to make sure nothing else is missing.
