Do I Need a Barcode to Sell on Amazon?

This was a question asked a few days ago at the Brightpearl Commerce Acceleration 101 I presented at a few days ago and I thought it’s worth sharing with you.

So do you need one?

Yes and no.

The answer really depends on if the product you are selling is already listed on Amazon or not and I’ll explain why.

If the product is already listed on Amazon

Then this is “happy days“, all we need is the key and key is something called an ASIN.

This is pronounced “A-SIN” and stands for “Amazon Standard Identification Number”. Once a product has been loaded onto Amazon, Amazon give the product a unique key that is not the barcode and looks like  this example “B003MWJKVI” which is for a memory stick.

If you pick any item on Amazon, you’ll notice that not only in the page URL you see the ASIN of the product like below:

An ASIN in the Amazon URL for a product

An ASIN in the Amazon URL for a product

Also the ASIN can be found further down the product page and looks like the screen shot below:

An ASIN in the Amazon product page

It should be noted that the ASIN still refers to the barcode (or the correct name is GTIN or EAN) but unlike where a barcode is meant to be for a single product only, an ASIN can refer to more than one barcode. Barcodes are leased not bought and can be re-used, hence that’s why you can some times find a barcode belonging to more than one product on Amazon.

Oh, if you’d like know the differences between an ASIN, GTIN, EAN, UPC or JAN then take a look at this article, as I covered that last year and a video explanation is also included too.

If the product is not listed on Amazon

Now this is not “bad days”, it just means that we need to locate the barcode for the product.

Most mainstream products have barcodes assigned and are on the product itself, just look for the numbers below the stripy label. However if you’ve got a product that is new or undocumented on Amazon, then you’re going to need a barcode to create it on Amazon with.

There are a collection of sites on the interwebs that you can buy a barcode for a few pounds, these are fab if you only have a few products, but I’m guessing you have lots and this where you need to speak to a company called GS1. You can find them here http://www.gs1uk.org/.

Barcodes are not bought, they are leased

This means that you can lease a range of barcodes and if you’re wondering “how many do you get?” basically you are given as many as you need. This could be 10,000 this could be several million depending on your requirements.

To subscribe to GS1, the rough prices are £250 for the first year and £125 for the next years subscription as the first year they charge you ~£125 set up fees. But you get as many barcodes as you need to use and if you run out, you can go back and ask for more.

A full break down of the pricing can be found here: http://www.gs1uk.org/about-us/Pages/Become-a-member.aspx

Oh and how to find out the barcode of an ASIN?

Free ASIN to EAN ConverterThat’s a little more tricky if you have lots of products and you need to use the Amazon Product Advertising API to look them up.  But…. if you know the ASIN, then the tool at the link below will convert them for you, for free!

ASIN’s for Variation Products on Amazon

If you want to know the ASIN’s of the variations of products listed on Amazon with variations, you may wish to contact me directly as I have a script that I use with clothing and footwear businesses to look the variation ASIN’s up on Amazon for existing products, all in a deliciously simple CSV file for it’s output.

Hope that helps!

    Hi Matt! When we went live on Amazon in January I referred back to the notes I made when we discussed Amazon, ASINs and bar codes way back in 2011 – it all makes sense until you want to list a product that is already available. 9 times out of ten the product is duplicated over and over and therefore there are multiple ASINs for exactly the same product – so which ASIN do you use for your inventory item? There’s no simple answer according to Amazon – the problem exists because sellers create a new listing for their product rather than using an existing ASIN.

    Confusing!

    The ASIN for variation products info sounds useful Matt – could you send it over when you get chance?

    • Howdy Gill,

      The simple answer is all of them :)

      Need to careful with unbranded products as some sellers can be fiercely protective of them. For the variations, yea I need to package that up properly and it’s in the todo list.

      Matt

        All of them? Why didn’t I think of that? Not the best lateral thinker am I? Thanks Matt – I’ve been tussling with that one for a while now.
