Amazon Error 8560: How to Fix "SKU Does Not Match Any ASIN"

Applies to inventory flat file uploads via Seller Central · Updated July 2026

The full message in your processing report reads something like: "SKU ABC-123, Missing Attributes feed_product_type. SKU ABC-123 does not match any ASIN. Creation of a new ASIN requires the following missing attributes: …"

Error 8560 is really two statements stapled together: (1) the product ID you supplied didn't match anything already in Amazon's catalog, and (2) your row doesn't contain enough data for Amazon to create a brand-new listing instead. Which fix is right depends on what you were trying to do.

First, decide which case you're in

You intended to…	What 8560 means for you	Fix
Match an existing Amazon product (yours or another seller's)	Your product ID is wrong, malformed, or mangled by Excel	Case A below
Create a new listing	The ID is fine (and genuinely new) — but required columns are empty	Case B below

Case A: The product ID should have matched

Work through the ID itself — the column pair is external_product_id and external_product_id_type:

Check the length. UPC = exactly 12 digits, EAN = 13, ISBN = 10 (older ISBNs can end in X), GTIN = 14. A truncated or padded code matches nothing.
Check for Excel damage. This is the big one: Excel strips leading zeros from anything it treats as a number, and long codes get rewritten in scientific notation (8.85911E+11). Format the external_product_id column as Text, then re-paste the real codes.
Check the type matches the code. A 13-digit EAN declared as UPC fails. The value in external_product_id_type must agree with the actual format.
Validate the code. Run it through a GS1 / barcode check-digit validator. A code that fails checksum was mistyped somewhere upstream — often one swapped digit.

UPCs starting with 2 or 4 are a silent trap. These ranges are reserved for "local use" (store-internal barcodes), and Amazon's catalog ignores them — the system behaves as if you submitted no product ID at all, and you land in 8560 even though the barcode scans fine in your warehouse.

Fixed the ID? Re-upload and the row should match. If the ID is definitely correct but the product truly isn't in Amazon's catalog yet, you're actually in Case B — Amazon needs full data to create it.

Case B: You're creating a new listing — fill what's missing

The error message lists the missing attributes by name — Missing Attributes feed_product_type is the most common. But the listed ones are just the columns Amazon checked first. To create a new ASIN, a row generally needs all of these populated:

Column	What goes in it
`feed_product_type`	The product type for your category — pick from the Valid Values tab of the template, exact spelling. The single most commonly missing attribute.
`item_sku`	Your unique SKU for this row
`external_product_id` / `external_product_id_type`	The UPC/EAN/GTIN and its type (or leave both blank only if you have an approved GTIN exemption for the brand)
`item_name`	Product title
`brand_name`	Brand — must be consistent across the family if you're building variations
`standard_price`	Price (children of a variation family each need one)
`quantity`	Stock for merchant-fulfilled listings
`main_image_url`	Publicly reachable image URL
`item_type_keyword`	Classification keyword — check Valid Values for accepted terms

Plus whatever your specific category marks as Required in the template's Data Definitions tab — apparel needs sizes and colors, consumables need expiration attributes, and so on.

Use a current template

Amazon adds required attributes to categories over time. A file built on last year's template can be missing entire columns, and you'll get 8560 no matter how carefully you fill what's there. Download a fresh one: Catalog → Add Products via Upload → download a category template, and re-check the Valid Values tab — accepted values shift between template versions too.

Still getting 8560?

The brand is gated or registered to someone else — creating new ASINs under a registered brand you don't own gets blocked at this stage. Check whether the brand requires approval in your marketplace.
You meant to match but used only the SKU — SKUs are seller-internal; they never match other sellers' listings. Matching happens via external_product_id or ASIN.
Half the row is from another category's template — columns pasted across templates carry headers Amazon doesn't recognize for your product type, so required fields effectively stay empty.
