Routing Numbers
Warning
To use this type, you need to install the optional pydantic-extra-types package:
pip install pydantic-extra-types
The ABARoutingNumber
type validates ABA routing transit numbers.
from pydantic import BaseModel
from pydantic_extra_types.routing_number import ABARoutingNumber
class BankAccount(BaseModel):
name: str
routing_number: ABARoutingNumber
account_number: str
account = BankAccount(
name="John",
routing_number="122105155",
account_number="123456789",
)
print(account.routing_number)
# > 122105155
The algorithm used to validate the routing number is described on this section of the Wikipedia page.
