# `Bic`

A bank's identifier code, also called a SWIFT code: 8 or 11 characters.

Use it to name a bank in an international payment. For the account at that bank, use [`Iban`](/docs/types/type-iban.md).

## Shape

One value, held as text in one set form, with no parts: `NWBKGB2L`.

## Example

```jadpo
Bic("DEUTDEFF")
```

`Bic(raw)` checks the text, and text that isn't one breaks the `format` rule.

`text.parse(raw, as: Bic)` reads one from text that comes from outside. Text that isn't one at all fails `malformed`, such as `DEUTDEF`, `deutdeff` or `DEUTDEFF50`.

## Good to know

- `==` tells you whether two are the same. `<` and `list.sort_by` don't take it.

## In JSON

A string, in a request, a response or `json.write`:

```json
"DEUTDEFF"
"DEUTDEFF500"
"NWBKGB2L"
```

## Details

<details>
<summary>Text form, storage, how it is shown, and operations</summary>

`Bic` is in the group Money and banking, and has been in Jadpo since 0.1.0.

### Text form

`text.from` writes one standard text form, the same form `text.parse` reads back: `DEUTDEFF`, `DEUTDEFF500` and `NWBKGB2L`.

### How it is stored

It is stored in one column named for the field, of type `text`. `DEUTDEFF500` is stored as `'DEUTDEFF500'`.

### How it is shown to people

`text.format(value, locale:)` shows it to people in their locale.

With `locale: Locale.en_gb`:

| Value | Shown |
|---|---|
| `DEUTDEFF` | `DEUTDEFF` |
| `DEUTDEFF500` | `DEUTDEFF500` |
| `NWBKGB2L` | `NWBKGB2L` |

### Operations

It also takes `text.parse`, `text.from`, `text.format`, `json.read`, `json.write` and `==`. [How every standard type behaves](/docs/every-standard-type-meets-one-contract.md) says how they work.
