Multiple ASINs for an EAN

[racke]

It is possible that Amazon assigns multiple ASINs for the same EAN. I ran into that when retrieving ASIN's for EAN's from the Icecat catalog:

ASIN: $VAR1 = {
          'MarketplaceASIN' => {
                               'ASIN' => 'B000KJOI7W',
                               'MarketplaceId' => 'A1PA6795UKMFR9'
                             }
        };
ASIN: $VAR1 = {
          'MarketplaceASIN' => {
                               'MarketplaceId' => 'A1PA6795UKMFR9',
                               'ASIN' => 'B0041M5CHY'
                             }
        };
ASIN: $VAR1 = {
          'MarketplaceASIN' => {
                               'ASIN' => 'B001JYJUIY',
                               'MarketplaceId' => 'A1PA6795UKMFR9'
                             }
        };

If you are asking, if multiple ASIN can have the same UPC/EAN. The answer is yes. This generally happens when ASIN are split or otherwise worked on for various issues by seller-performance and/or catalog team.
