Check Serial Number

Parsing the Check Serial Number
Most banks print the check serial number in three easily recognizable
spots. The printer firmware will look for the number in these spots,
using the following ordered algorithm. The examples use letters to
represent symbols on the check:
A number bracketed by "on us" symbols in the auxiliary "on us" field
is the check serial number.
occcccco txxxxxxxxxt xxxxxxxxo
Otherwise, a three or more digit number to the right of the rightmost
"on us" symbol, and to the left of the leftmost amount symbol if an
amount field is present, is the check serial number.
txxxxxxxxxt xxxxxxxxo cccc
txxxxxxxxxt xxxxxxxxo cccc $xxxxxx$
If both of these searches fail to produce the check serial number, extract
the whole account number field from between the rightmost transit
symbol and the rightmost "on us" symbol. A three, four, or five-digit
number to the right of the rightmost transit symbol, separated by a
space or a dash from the rest of the account number is the check serial
number.
txxxxxxxxxt cccc xxxxxxxxo
txxxxxxxxxt cccc-xxxxxxxxo
txxxxxxxxxt cccc xxxxxxxxo xx
t Transit symbol
o "on us" symbol
$ Amount symbol
- Dash
c Check serial number
x Any other number
