Bottle Code

From a Reddit topic and some other websites I came across this information. It is not guaranteed but repeated many times over. It acts as a a guidance and any input about errors or other years is highly appreciated.


U and V were skipped. So was X. 2011-2013 must correspond to 3 of the following 7 letters: L, M, N, O, P, Q, or R. I am assuming O was skipped for obvious reasons. Probably L and Q too.

So my guess is as follows.

  • 2004 = D
  • 2005 = E
  • 2006 = F
  • 2007 = G
  • 2008 = H
  • 2009 = J
  • 2010 = K
  • 2011 = M or N
  • 2012 = P
  • 2013 = R
  • 2014 = S
  • 2015 = T
  • 2016 = W
  • 2017 = Y
