our procedures aren't that detailed, ie: they won't help you any. here's what i did at my old bank for on us checks... check id of person cashing check. if a non-customer, check 2 id's and get a fingerprint/thumbpint. check the accoutn the check is drawn on-- see that the accoutn has money in it, see if the check is in sequence (within reason, ie: check presented is #600 but customers checks clearing at the time are only in the 400's- this is bad). also check for notes such as stop payments or flags such as "customer lost checkbook," "attempted fraud on account." if these things don't check out, or if they do but you are still wary or the check is large enough that you want to be sure of it before cashing it, you can contact the customer to see if they wrote/authroized the check. we used to do this all the tiem at my old job, and it worked out.
