MICR E-13B

MICR E-13B is used in financial applications to encode bank account numbers, bank routing numbers, check numbers, and other information on a single row. There are standard guidelines for how data is represented on checks and other financial documents, but a great deal of flexibility is left to the discretion of the document designer. As a result, the internal MICR template reads any MICR string whose length is between 4 and 40 characters. Only one consecutive space is allowed in a template. On many checks, the MICR string contains fields separated by more than one space. These fields will be read and output as individual MICR strings. Because of the wide variety of strings that will produce MICR output, users are cautioned to check for partial reads of MICR text where only part of the targeted MICR string is actually in the image.
