# Add UIN (Unique Identification Number) to the Assembly Order

```http
PUT /api/v3/orders/{orderId}/meta/uin
```

**Base URL:** `https://marketplace-api.wildberries.ru` · **Module:** [`orders-fbs`](https://valeryverkhoturov.github.io/wb-api-client-docs/en/reference/api/orders-fbs/) · **Section:** FBS Label Identifiers · [Specification doc ↗](https://dev.wildberries.ru/en/docs/openapi/orders-fbs#tag/fbsLabelIdentifiers/operation/putV3OrdersOrderIdMetaUin)

Sets the UIN for the assembly order. The assembly order can only have one UIN.
You can add UIN to the assembly order only if the `uin` field is returned in the response of the [Assembly Order Label Identifiers](https://dev.wildberries.ru/openapi/orders-fbs#tag/fbsLabelIdentifiers/operation/postV3OrdersMeta) method, and the assembly order is in the `confirm` status.

[Request limit](https://dev.wildberries.ru/openapi/api-information#tag/introduction/Rate-Limits) per one seller account for all methods for **adding FBS label identifiers**:

| Period                                                           | Limit         | Interval | Burst       |

| One request with `4XX` response codes is counted as 10 requests. |
