# Officially, bank accounts in the UK can be between 6 and 10 digits, but
# the standard is 8, and any system that receives them will require them to
# be zero-padded. Customers should be used to prepend zeroes, and it should not be an issue.
# If this becomes an issue, lets consider handling auto-zeropadding, but it is both
# less technical issues and easier to give feedback to the user if we enforce the 8 digit length rule.
