# Create a card

When you create a new credit card, you must specify a customer or recipient on which to create it.

If the card’s owner has no default card, then the new card will become the default. However, if the owner already has a default, then it will not change. To change the default, you should [update the customer](https://docs.stripe.com/docs/api.md#update_customer) to have a new `default_source`.

## Returns

Returns the `Card` object.

## Parameters

- `source` (object | string, required)
  A token, like the ones returned by [Stripe.js](https://docs.stripe.com/docs/js.md) or a dictionary containing a user’s card details (with the options shown below). Stripe will automatically validate the card.

  - `source.exp_month` (integer, required)
    Two-digit number representing the card’s expiration month.

  - `source.exp_year` (integer, required)
    Two- or -four-digit number representing the card’s expiration year.

  - `source.number` (string, required)
    The card number, as a string without any separators.

  - `source.object` (string, required)
    The type of payment source. It should be `card`.

  - `source.address_city` (string, optional)
    City / District / Suburb / Town / Village.

  - `source.address_country` (string, optional)
    Billing address country, if provided.

  - `source.address_line1` (string, optional)
    Address line 1 (Street address / PO Box / Company name).

  - `source.address_line2` (string, optional)
    Address line 2 (Apartment / Suite / Unit / Building).

  - `source.address_state` (string, optional)
    State / County / Province / Region.

  - `source.address_zip` (string, optional)
    ZIP or postal code.

  - `source.currency` (string, optional)
    Required when adding a card to an account (not applicable to customers or recipients). The card (which must be a debit card) can be used as a transfer destination for funds in this currency.

  - `source.cvc` (string, optional)
    Card security code. Highly recommended to always include this value, but it’s required only for accounts based in European countries.

  - `source.default_for_currency` (boolean, optional)
    Applicable only on accounts (not customers or recipients). If you set this to `true` (or if this is the first external account being added in this currency), this card will become the default external account for its currency.

  - `source.metadata` (object, optional)
    A set of key-value pairs that you can attach to a card object. This can be useful for storing additional information about the card in a structured format.

  - `source.name` (string, optional)
    Cardholder’s full name.

- `metadata` (object, optional)
  Set of [key-value pairs](https://docs.stripe.com/docs/api/metadata.md) that you can attach to an object. This can be useful for storing additional information about the object in a structured format. Individual keys can be unset by posting an empty value to them. All keys can be unset by posting an empty value to `metadata`.
