There are several possible reasons why some prenumbered checks are missing from the sequence of
canceled checks returned with a bank statement. Reasons include: (1) Some of the checks in the numbered
sequence may have cleared the bank in a previous period and were returned with the bank statement in that
previous period. (2) Some of the checks in the numbered sequence may remain outstanding. If so, they will
be returned with the bank statement in a later period when they clear the bank. (3) The issuer of the checks
may have voided one or more of the checks in the numbered sequence, perhaps because of making an error
in writing the checks. (4) Occasionally, a check will reach the bank but the bank will incorrectly charge the
check to the wrong account. When the bank detects the error, it will return the check separately with a note of
explanation to the depositor.
