# BANK-KOR-AON

> Looks up the account holder name of a Korean bank account using a bank code and account number.

Looks up the account holder name of a Korean bank account using a bank code and account number.

* **ARGOS does not compare names.** It passes on the account holder name returned by the bank as is. Comparing it with your member's name is up to you.
* `MATCH` means "the account was confirmed and the account holder name was received".
* Once the bank answers, the call is billed whatever the verdict. Calls that do not produce a verdict return `4xx` or `5xx` and are not billed.
* Available in every region (US and KR).

> [!TIP]
>
> When the account holder name does not exactly match your member's name, use [TXT-FZ-MAT](https://developers.argosidentity.com/en/idcheck/unit-api/txt-fz-mat.md) to get a similarity score and tell spelling differences (such as `홍 길동` and `홍길동`) from different people.

Values can be added to `verdict` and `verdictReason`. [Reading verdicts](https://developers.argosidentity.com/en/idcheck/unit-api/overview.md#reading-verdicts)

## Notes

* See [Bank codes](https://developers.argosidentity.com/en/idcheck/reference_tables/bank-codes.md) for the list of bank codes.
* `accountHolder` is passed on exactly as the bank returns it, so **it can include leading or trailing spaces (including full-width spaces).** Trim it before comparing it with your member's name.

## Billing

The billing unit is `response`, and each call has a `count` of 1. `MISMATCH` is also billed.
