**NCIC FPC Filing Sequence
Formula**

J. Washington

**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 114 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 distinguished 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.**

**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 114 possible codes for each segment the
total number of combinations is 3.707221314118566e+20.**

**Example: **** **

**(2.6) X (11.40001) X (11.20002) X (0.60003) X (1.60004)
X (11.30005) **

**X (7.00006) X (11.10007) X (0.80008) X (2.20009) = ****492586.9358**

**In conclusion, the NCIC FPC code, 14XXAACO04SR59TTDM10 **

**would be filed as ****492586.9358 ****between ****1.00451E-10 ****and ****37,073,676,543.**
