The first two digits should be either 0-12 or 21-32 or 61-72 or 88. Also the checksum should match (there’s an algorithm for its calculation). It’s a standard so if you use for routing number indeed, it should match.
The routing number must be 9 digits and even though these numbers are valid in your country, our default routing number follows the ABA Routing number for American formats. I would recommend creating a custom field as a text for tracking the routing number of your employees. To create the field, please go to Settings > Employee Fields and create it in the same category as the default routing number field.
