In the article Magento 2: How to make customer attribute? describe it step by step.
Customer attributes can be used in different forms, this example will show customer attribute at the admin customer edit page. You can also use also other forms. For example:
“used_in_forms” => [‘adminhtml_customer_address’, ‘customer_address_edit’, ‘customer_register_address’]
