Different part numbers for 2tb my passports on amazon

Hi, i was about to purchase a  2tb my passport, on the uk amazon site, but noticed there are two different numbers at different prices. Before I purchase one could anyone clarify the difference, please : WDBY8L0020BBK-EESN and
WDBY8L0020BBK-NESN. Tried using their support portal, but sends me in a loop :frowning:

Thanks all!

It’s the same hard drive, the second part after the model number is not important, so go with the cheaper one. Check the link below for the steps to create the tech support email.
