# Update Identification

`PATCH /identifications/{id}`

## Request

- Base URL: `https://app.moderntreasury.com/api`
- URL: `https://app.moderntreasury.com/api/identifications/{id}`
- Auth: HTTP basic

Updates a single `identification` in place. Only the fields you supply change; omitted fields keep their stored values, so there is no need to resend the legal entity's other identifications or to know the stored `id_number`.

To attach a document to an existing identification, use [Create Document](ref:create-document) with `documentable_type=Identification`.

## Path parameters

- `id` string, required

## Request body

- object
  - `id_type` string: The type of ID number. See list of [Identifications](ref:identifications).
  - `id_number` string: The ID number of the identification document. A taxpayer id number can only be changed while the legal entity is `pending` or `suspended`.
  - `issuing_country` string: The ISO 3166-1 alpha-2 country code of the country that issued the identification. Not needed for ID types with a country code prepended.
  - `issuing_region` string: The sub-national region (state, province, territory) that issued the identification document. For a US driver's license issued in California, this would be "CA".
  - `expiration_date` string, date: The date when the Identification is no longer considered valid by the issuing authority.
