# Unblock card PIN

**POST** `/issuing/cards/{card_id}/pin/unblock`

Unblock a card's PIN without changing it, for example after you verify the cardholder. A PIN is blocked after 3 wrong PINs in a row on transactions. Unblocking clears the block and the count of wrong PINs, and sends an `issuing.card.pin_unblocked` event. Unblocking a card whose PIN isn't blocked succeeds without an event.

### Path Parameters

- `card_id` `string` _(required)_ — Unique identifier for the card.

**Response 200**
