mots on:e dvd region help

hope it’s okay to post this here! so i recently ordered the mots on:e dvd. today i looked in the description of the product on the site i ordered from and i noticed it said “3 Discs (Region Code: 1, 3, 4, 5, 6)”

i have no idea what that means. will i be able to play it? is it region locked? i live in europe and i ordered this from a local store i always buy from. sorry for the dumb question but i’m really excited for it because i’ve never bought something like this before
