# Financial Institution Identification

## Using with Account Id

An account ID (*`ACCT`*) only specifies the account, not the financial institution that holds that account. Therefore when the *`ACCT`* address type is selected, the Account Identification must always be used in conjunction with one of the `Financial Institution Identification` types in the table below.

When the address type is ACCT, the response from the `Address Inputs` API will automatically include a field for the Financial Institution Identification.
{% endhint %}

### Using with a Proxy

{% hint style="info" %}
In some countries, such as the Philippines, the same proxy can be registered to multiple financial institutions. Therefore it is necessary to collect the Financial Institution Identification for the Recipient. In these (rare) cases, the response from the Address Types API will automatically include a field for the Financial Institution Identification.
