I don't think the numbers are important. I had misplaced my card and requested a new one last month. I just got it yesterday and wheras I had found my other one I checked the numbers and they are both 7 digits, the original has a number of 0008255 and the new one is number 0000131. On the paper it is stuck to it is part of a much larger series of numbers. 514-025-000000131-PMNM-D.So who knows????????????????????
