# Create a new external address

`POST /accounts/{account_id}/addresses/external`

Creates a non-custodial address (EOA) for the specified account.

## Path parameters

- `account_id` string, ksuid, required

## Headers

## Request body

- union
  - object
    - `name` string, nullable, required
    - `address` string, required
    - `transfer_types` string[], required
  - object — Address fields are conditional. `bank_address` and `beneficiary_address` are required when `transfer_types` includes `wire`. They are optional for `ach_credit`, `same_day_ach_credit`, and `rtp_credit`. For ACH/RTP-only addresses, do not provide placeholder or generic bank addresses—omit these fields unless you have accurate values.

      - `state` string, required
      - `zip` string, required
    - `transfer_types` string[], required — Rails to enable for this bank endpoint. If this array includes `wire`, the request must include `bank_address` and `beneficiary_address`. For ACH/RTP-only addresses, those address fields are optional.

## Response `201`
