The
NCIC FPC contains 20 characters, each pair of characters represents one digit beginning
with the right thumb as the No. 1 digit and ending with the left little finger
as the No. 10 digit; the left thumb is then No. 6. For every consecutive pair of characters, one
code can be assigned out of a possible 115 codes (from PI to XX
). This means that there are
actually only 10 individual segments for the NCIC FPC code ,
with each one maintaining a pair of the 20 characters to represent an
individual code.
Let (X) equal the number of assigned to the NCIC FPC
code.
Each
of the ten segments with the exception of segment #1,
must be assigned a decimal number which shall be added to the assigned number
for the given NCIC FPC Code.

This adding
of the decimal number to the assigned number for the NCIC FPC code must be done
in order to establish a unique numerical value to each segment of the
ten-segment unit. Segment number 1,
however, need not be assigned a decimal value because the other nine segments
maintain an identity distinguishable from it.
( The reason for choosing #1 segment as the one
which shall not be assigned a decimal value is because #1 segment is the only
segment which can provide us with the lowest possible number in the calculation
if no decimal was to be added to it. )
It can be noted that in this way no two or more segments can provide the
same exact number. Furthermore, no two
NCIC FPC codes can provide the same filing number, even if the original code
appeared in a reverse sequence.

Added To The
Assigned
Number
After
the decimal number is added to the assigned number for the NCIC FPC code,
multiplication takes place. That is, #1
segment times #2 segment and that product multiplied
by #3 segment, and so on until #10 segment has been included in the
multiplication. The end product shall
provide the filing location for the given NCIC FPC code.
When
there are ten segments and 115 possible codes for each segment, the total
number of possible combinations is approximately 4.04557E+20 or exactly 404,555,773,570,791,015,625.
Example: ( 2.6) X ( 11.50001 ) X (
11.30002 ) X ( 0.60003 ) X ( 1.60004 ) X ( 11.40005 ) X ( 7.10006 ) X (
11.20007 ) X ( 0.80008 ) X ( 2.20009 )
= 517,628.2327.
In conclusion, the NCIC FPC code 14XXAACO04SR59TTDM10
would be filed as the 517,628.2327th code between 1.00451E-10 and 40,457,160,428.
