Variarions get all same ean code

Hi @joeygr,

Could you please let me know:

1. Which “Type” have you set in “WooCommerce > Settings > EAN > General”?

2. What is your latest product ID? Is it over 10000?

3. Did you set anything for the “Seed prefix (optional)” option in “WooCommerce > Settings > EAN > Tools > Product Tools > Generate”?

Hi @joeygr,

Thank you for the reply.

I think I know what’s going on. You are generating EAN-8 codes, and EAN-8 consists of a 3-digit country prefix, 4-digit “seed” (i.e. product ID), and the last digit is a checksum digit. Now, as you’ve crossed 10000 product IDs recently, your EANs ran out of “free space” (as your product ID has 5 digits now, not 4 as we need it in the EAN-8 case).

Now regarding the solution – coincidentally we had exactly the same question from one of our other customers recently, and we’ve added a new option for him to our plugin – “Country prefix length”. It allows using a 2-digit country prefix instead of a 3-digit. This new option is currently in our development version – we are going to release it to the public a bit later today. I will get back to you as soon as it’s released.

Hi again, @joeygr,

As promised, we’ve just released a new plugin version (v3.3.0), where I’ve added new “Country prefix length” option to “WooCommerce > Settings > EAN > Tools > Product Tools > Generate”. Set it to 2. Please note that this will work only for the EAN-8 type – other types will always use 3. Give it a try and let me know what you think.

One note though – we will get the same problem when you will reach 100000 products. The most obvious solution to this is to use EAN-13 instead of EAN-8. Even though theoretically there is a limit of products in EAN-13 as well, in reality, there is no way any site will have so many products.

@joeygr,

Happy to hear it’s solved 🙂 Please let me know if you need anything else.

And if you like the plugin, please consider leaving me a rating.
