I have received a bluemiles card to replace my bluemiles card. Why is the card number different?

As long as the first 12 digits on your card are the same as on the bluemiles card, the card is to all intents and purposes the same. The last four digits on the bluemiles card only indicate the card version.
If, however, the first 12 digits on your card should differ from your bluemiles card number, then please contact our bluemiles team at 0049 (0) 1805 / 45 22 45,  Mondays -Fridays 08.00-20.00 and Saturdays - Sundays 10.00-19.00.
