In case you resell different manufacturers’ merchandise by means of FBA, the 2026 guidelines additionally modified what goes on the field. This information covers each circumstances, the prices, and the errors that get listings suppressed.

What a GS1 barcode truly is
A World Commerce Merchandise Quantity (GTIN) is the distinctive quantity behind the black bars. The bars are simply the image of it. GS1 is the group that maintains the worldwide commonplace, and GTINs come completely from GS1.
You will note a number of codecs:
- GTIN-12 (UPC-A): the 12-digit code used primarily in North America.
- GTIN-13 (EAN-13): the 13-digit code used worldwide.
- GTIN-8: a brief code for very small packages.
GS1 explains that a GTIN will be encoded in numerous barcode varieties, similar to EAN-13, UPC-A, EAN-8 and UPC-E, relying on the place the merchandise is scanned. For databases, GS1 recommends storing each GTIN as 14 digits by including main zeros.
Consider the GTIN as your product’s passport quantity. A passport photograph (the barcode) is simply legitimate if the quantity behind it’s actual and belongs to you.
Why Amazon cares who issued the quantity
Amazon doesn’t simply test {that a} code has the appropriate variety of digits. In response to GS1 US, Amazon verifies product IDs in opposition to the official GS1 database, and codes that don’t match are thought-about invalid. The danger is itemizing suppression.
That’s the reason for the most typical newbie mistake. GS1 says sellers attempt to skip the licensing step by shopping for low-cost codes from third-party resellers. These numbers typically belong to different firms, which results in catalog duplicates, rejected listings and attainable everlasting suppression of product pages.
You may see how this performs out within the wild. In a Vendor Central thread, one vendor described paying $30 for a code and discovering that Amazon didn’t acknowledge it after 27 days. Each case differs, however the lesson is constant: a code is simply nearly as good as its registration report.
Why this additionally issues on your personal website
Your GTIN doesn’t simply dwell on Amazon. In case you additionally promote by yourself retailer, the identical quantity belongs in your product knowledge, and structured knowledge helps engines like google learn it. A walkthrough of ecommerce schema markup varieties so as to add first reveals how product particulars are marked up for service provider listings. One identifier, used persistently all over the place, makes catalog matching simpler.
GS1 barcode vs. FNSKU: two completely different jobs
That is the place most new sellers get confused, so right here is the plain model.
| GS1 barcode (UPC/EAN) | Amazon FNSKU | |
|---|---|---|
| Issued by | GS1 | Amazon |
| Identifies | The product, globally | The product and the vendor, inside Amazon |
| Works on different channels | Sure | No |
| Required to create an inventory | Normally sure (until exempt) | No, created after the itemizing exists |
| Printed by | Your producer or packaging designer | You, a prep middle, or Amazon |
For FBA, sellers have two selections: the producer barcode or an FNSKU. The FNSKU is inside to Amazon and may’t be used for different retailers. A GS1 barcode identifies stock persistently throughout platforms.
That portability is the true argument for proudly owning a GS1 GTIN. In case you construct a model, you’ll most likely need to develop past one market. A GS1 code enables you to transfer into different marketplaces, bodily retail and provide chain companions with out repackaging. An FNSKU-only product stays locked to Amazon.
In order for you a deeper take a look at how the product ID, ASIN and barcode relate, our information on ASIN to barcode and UPC lookups walks by means of it. For the ASIN itself, see what an Amazon ASIN is and the way it’s created.
The March 31, 2026 FBA change
That is the half many older tutorials get incorrect.
Amazon informed sellers that beginning March 31, 2026, resellers can now not depend on producer barcodes for FBA. One vendor reported an ASIN blocked from replenishment for utilizing a UPC as an alternative of an FNSKU and quoted the discover. Commerce protection describes the identical rule: non-Model Registry resellers should use FNSKU barcodes on all FBA stock, even when the product already carries a UPC.
In observe, it really works out like this:
- You personal the model and are enrolled in Model Registry: you’ll be able to hold utilizing the producer barcode on models, with no additional sticker.
- You resell, otherwise you’re a non-public label vendor not but in Model Registry: label each unit with an FNSKU, even when a reliable GS1 barcode is already printed on it.
For this reason Model Registry and a correct GS1 GTIN now go collectively. The GTIN will get your itemizing created and matched. Model Registry lets the producer barcode do its job in FBA. Guidelines like this could change, so affirm your account’s present necessities in Vendor Central earlier than you ship.
In case you’re nonetheless mapping out the entire path from product to cargo, our Amazon FBA step-by-step playbook and the information to FBA personal label cowl the encircling steps.
The best way to get a GS1 barcode for Amazon
- Resolve what number of merchandise (and variations) you’ll launch. Every variation, similar to a special shade or dimension, typically wants its personal GTIN.
- Go to your nationwide GS1 member group. Within the US, that’s GS1 US. Different nations have their very own, similar to GS1 UK and GS1 Australia.
- Select a single GTIN or an organization prefix. A single GTIN fits one product. An organization prefix enables you to generate many GTINs your self.
- Register your merchandise within the GS1 knowledge instruments. Assign every GTIN to a particular merchandise and hold a spreadsheet mapping GTIN, SKU and ASIN.
- Give your printer or producer the precise GTIN. Ask for a proof earlier than mass printing.
- Enter the GTIN once you create your itemizing. Amazon matches it in opposition to the GS1 report.
A fast be aware for non-US sellers: the marketplace for GS1 costs and guidelines is country-specific. A US prefix will not be the identical as one issued in your house nation, and Amazon marketplaces exterior the US might have their very own expectations. Verify your native GS1 workplace.
What GS1 barcodes price
Costs change, so affirm on the GS1 US website before you purchase. As of a 2026 pricing breakdown, a single GS1 US GTIN is listed at $30 and an organization prefix overlaying as much as 10 merchandise at $250, with annual renewal charges hooked up. One other vendor information describes the one GTIN as having no annual renewal, so the 2 sources disagree. That’s precisely why you need to learn the present payment schedule on GS1’s personal web page moderately than belief a abstract, ours included.
Two sensible methods to consider the mathematics:
- One product, unsure future: a single GTIN retains the upfront price low.
- A line with variations or a rising catalog: a prefix often works out cheaper per code and retains every thing underneath your organization identify.
Additionally issue the price of the product launching on Amazon itself. Our FBA charges breakdown reveals the best way to test whether or not an ASIN nonetheless makes cash after charges.
Resale barcodes: the shortcut that backfires
You will note adverts providing UPCs for a number of {dollars} with guarantees of Amazon approval. Some sellers get away with it for some time. Right here is why we advise in opposition to it.
- Possession is murky. If the code was beforehand assigned contained in the GS1 system to a different firm, Amazon’s validation might floor that.
- You may’t show the code is yours. Model Registry and a few class approvals ask for model proof. A barcode registered to a stranger doesn’t assist.
- The harm lands in your itemizing, not the vendor of the code. Suppressed pages and duplicate catalog entries price you evaluations and time.
When you’ve got a small catalog and need an possibility that’s not a full GS1 license, Amazon gives a GTIN exemption for sure merchandise. Eligibility is category-specific, and an exemption doesn’t offer you a conveyable barcode for different retailers. Verify the necessities in Vendor Central earlier than deciding.
Our earlier piece on discovering UPC codes for Amazon goes by means of the choices from a vendor’s funds perspective.
FNSKU label guidelines: get them proper the primary time
While you do want FNSKU labels, the small print matter. Vendor steerage on Amazon’s discussion board says labels should be:
- Printed in black ink on white, non-reflective materials.
- Between 1 and a pair of inches tall and a pair of to three inches extensive. The default is 1 x 2 5/8 inches, which inserts widespread 30-up label sheets.
- Scannable, unobstructed, and utilized instantly over the unique producer barcode.
- Saved off seams, edges and curved surfaces. A label throughout a seam or curve can’t be scanned in a single cross.
Amazon’s personal April prep sequence for sellers stresses the identical factors: cowl the unique barcode, keep away from seams and edges, and label every particular person unit.
Why so strict? As a result of a sloppy label is a standard cause for receiving delays. Skilled sellers report that partially coated or folded labels gradual check-in at achievement facilities and may result in additional guide processing charges or models marked unfulfillable, as mentioned in this vendor thread.
Label it your self or pay Amazon
In case you can’t label models your self, Amazon has a label service. A seller-forum reply from March 2026 places it at $0.55 per merchandise. Confirm eligibility and the present payment in Vendor Central earlier than you construct it right into a delivery plan. On 500 models, that may be a sizable line merchandise, so examine it in opposition to shopping for a label printer and sheets.
Our walkthrough on the best way to create and print FBA labels covers the printer settings, sheet selections and customary errors.
Our perspective
We now have watched sellers burn weeks on barcode issues that took ten minutes to stop. Right here is how we see it.
Resolve your mannequin before you purchase a code. In case you are constructing a model, the GTIN is a part of your id. Purchase it from the supply, hold the receipt and registration report, and deal with it like every other model asset. In case you are reselling, your GS1 scenario is usually another person’s downside, however your labeling workload simply went up.
Low cost is never low-cost right here. The $30 or $250 you spend on a reliable registration is small subsequent to the price of a suppressed itemizing with stock already in a warehouse. We’d moderately you begin gradual and clear than quick and fragile.
Plan for the rule to maneuver. Amazon modified FBA barcode dealing with with weeks of discover. Construct your course of so you’ll be able to label models both manner, and hold your GTIN information tidy so a coverage change is an inconvenience, not a disaster.
Don’t neglect the unit economics. Labeling charges, prep and returns all eat margin. Run the numbers earlier than you reorder.
