Hi there,
This is nothing we can help you from here. You'll need to get in touch with the retailer where you bought the game from.
If you bought Battlefield 1 from EA/Origin store, please get in touch with an EA Game Advisor here: https://help.ea.com/en/ and they can help you.
If you are playing on PS4 console, then there is currently an issue with the codes. Read more about that and keep you updated here: https://help.ea.com/en/help/battlefield/battlefield-1/battlefield-1-troubleshooting/
I get error code WC-40371-5 when redeeming my Early Enlister Deluxe Edition code, what do I do?
Workaround:
" We’re aware that some North American Early Enlister Deluxe edition codes on PlayStation 4 are giving error messages and coming back as invalid.
We’re actively investigating this right now and will keep you updated.
Please hold on to your code while we work on this."
Please let us know if you have further questions.
Best regards,
Timmie.
