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:
t Transit symbol
o “onus” symbol
$ Amount symbol
- Dash
c Check serial number
x Any other number
A number bracketed by “on us” symbols in the auxiliary “on us” field is the check serial number.
occccccotxxxxxxxxxtxxxxxxxxo
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.
txxxxxxxxxtxxxxxxxxocccc txxxxxxxxxtxxxxxxxxocccc$xxxxxx$
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.
