Trade-in reference number

[walkerx]

I got an email which says what my reference number is for Trade-In which is 7 digits, yet the packing label only has a 6 digit Trade-In reference. 

Has anyone else had similar difference and does it matter

Mines the same, missing the last digit. I'll probably print the email and put it in the box but they can match by IMEI and royal mail tracking ID as well, so hopefully they'll work it out.

I'm going to ring tomorrow but mine same it the last digit missing.
