Banks 

Bank numbers, account numbers and corresponding control digits do not follow a standard pattern in Brazil. You can, however, classify them according to the three types described below. Only for the third type (banco Bamerindo, for example), you must enter the account control digits directly in the account field, separated by a ‘-‘ from the actual account number:

XXX Bank number (e.g. 341 for Itaú)

Y Control digit for bank number (e.g. 7 for Itaú)

Z..Z Bank key (no leading zeroes, e.g. four digits for Itaú)

 

‘Itaú type’: Account: U...U Control : X

X: Control digit for combination of bank and account

‘Bradesco type’:Account: U...U Control : XY

X: Control digit for bank

Y: Control digit for account

‘Other type’ :Account: U...U-XY Control : Z

Z: Control digit for bank

XY: Control digits for account
