A little search of Google and Wikipedia confirmed that the 10 digits you need consist of: one digit (0 to 9), IATA 3-digit carrier code, and 6-digit human readable number printed on the tag. So it looksk like the 10-digit number beginning with 0220 is the correct one.
Can't find LH's Manchester Airport number but the general LH number in the UK is 0845 773 7747. The baggage centre number is 0871 945 9124 (24 hrs). yell.com lists 0871 945 9747 when searching for "lufthansa manchester airport". If you can't reach 08xx numbers from outside the UK, an alternative to try is 020 87503500 (also -3509) which is only open Mon-Fri 7.30am to 8.00pm.
Good luck!
