Generally speaking, the owner's petition needs to be accompanied by a copy of the owner's ID card. This is because the owner's petition was submitted by the owner, and the copy of the owner's ID card can prove the owner's identity.

But the specific situation depends on the requirements of the organization or department that submitted the petition. Some institutions or departments may not require a copy of their ID cards, but require other relevant documents. It is recommended to consult the requirements of relevant institutions or departments before submitting letters and visits.
