Was the coin with the same tracking # also an American Flag Micro geocoin?
Also, you've probably heard this already but a 0 can look like a O, B-8, S-5, etc.
TB3RWBF is the coin that is active with my coins tracking number, And i tried every possible "wrong" letter. The weirdest part is the activated coin, the owner says its a canadian flag coin but the icon show an american flag
