Maybe this will help you:

In 1981 the 10-digit V.I.N. changed to a 17-digit number that we still use today.

The year code changed from the 3rd digit to the 10th digit.

An example would be WPOAAO910BS120001.

WP0 (World producer code-W=Germany, P=Porsche, 0=division)

AA0 (VDS Vehicle destination) AAO is USA and ZZZ is Rest of World.

91 (First and second digit of Porsche type 911)

O (Test digit)

B (1981)

S (manufacturing location/ Stuttgart)

1 (Third digit of Porsche Type - 911)

2 (Body type-911SC coupe USA/Canada)

0001 Sequential Number.

But wait, there is the twist!, Capital letters A through Z and numbers 1 through 0 may be used in the V.I.N. itself, except the letters I, O and Q , for obvious reasons. In the year code only, the letter U and the number 0 are not used as well.

Here is the breakdown for those of you still counting on you fingers-

1980 (A), 1981 (B), 1982 (C), 1983 (D) 1984 (E) 1985 (F) 1986 (G) 1987 (H), 1988 (J), 1989 (K), 1990 (L), 1991 (M), 1992 (N), 1993 (P), 1994 (R), 1995 (S), 1996 (T), 1997 (V), 1998 (W), 1999 (X), 2000 (Y) Then after 2001 the 10 th digit changes to a number, 2001(1), 2002 (2), 2003 (3), 2004 (4) and so on. In 2010 the year designator will switch back to (A) again. 2011 (B), 2012 (C,) and so on.

For a more detailed look at the V.I.N. coding, pick up one of the Porsche Technical Specifications Bookletsfrom your local dealer. They are each about 100 pages of pure technical fact fun, including complete V.I.N. de-coding.

Another fun search is for option codes, check this site out for their Option De-coder
