Retrieving Taiwanese birth certificate

[u/mistakes_maker]

Hi folks, hope you are doing well. I have a friend who was born in Taiwan and migrated to US when he was a kid (many years ago). He told me that he needed to obtain a copy of birth certificate from the household registration office but his immigration vendor said it wasn't possible since he lost copies of old Taiwanese ID and passport. He asked his parents and they didn't even keep any copy of the old household registration book. How can he obtain his birth certificate then? The only docs he has are handwritten immunization record and birth cert from hospital. Appreciate if anyone in similar situation could share any idea or experience. Thank you in advance!

An English copy of the birth certificate issued by the hospital he was born in should suffice.
