Bank deposit

Field	Type	Description
`type`	string	`"BANK_DEPOSIT"`
`countryCode`	string	ISO alpha-3 of the destination bank
`accountNumber`	string	Account number, IBAN, or alias — format enforced per country
`accountNumberType`	string	Selects the rail on corridors that offer more than one — see below
`bankCode`	string	Bank, sort code, IFSC, CNAPS, or branch identifier
`routingNumber`	string	Secondary routing identifier (Brazil agência, Sri Lanka branch code)
`accountType`	string	`"CHECKING"` or `"SAVINGS"`

`accountNumberType` — alias rails

Some countries let one BANK_DEPOSIT carry either a conventional account number or an alias. The value changes which other fields are required:

Country	Values	Effect
India (`IND`)	`BBAN`, `UPI`	`UPI` puts a Virtual Payment Address (`user@psp`) in `accountNumber` and drops `bankCode`/`accountType`; `BBAN` requires all three
Mexico (`MEX`)	`BBAN`, `DIMO`	`DIMO` sends to a 10-digit phone number and requires `bankCode`; `BBAN` takes an 18-digit CLABE alone
United Kingdom (`GBR`)	`BBAN`, `IBAN`	`BBAN` requires the 8-digit account plus a sort code in `bankCode`

SEPA countries take an IBAN in accountNumber and have no accountNumberType — the IBAN's own country prefix is the rail.
