Sign up ×  Is there a way to determine a government bill's or
bond's maturity date by looking at its CUSIP?  For example, the
CUSIP for US T-Bills with a maturity of 12/1/11 is 9127953V1. As
you probably know, the first six characters of a CUSIP represent
the item in question (e.g. US TBills); the last digit is an
error correction code; the seventh and eighth characters are
specific to the maturity. So in this case, "3V" maps to 12/1/11.
Do you know the algorithm that's used to map the two digit code
to a maturity? I can obtain the maturity by hand using the
internet or Bloomberg but would prefer to have an algorithm if
possible. Any ideas?  share|improve this question  2 Answers 2
CUSIP and ISIN codes are issued in the US by CUSIP Global
Services, run by S&P. While the data structure follows a certain
logic, there is no way to extract relevant security information
from the number. You generally have to rely on a data vendor for
specific data such as the maturity date for a bond.  In the case
