Because tax registration requires a copy of the code certificate.
The code certificate requires the original and copy of the business license, the copy of the legal person's ID card and the copy of the business opening notice.
It's all B5 paper.
After the code certificate comes down, A4 will make two copies, 2 legal person ID cards, 2 articles of association, 2 house lease agreements and 2 house title certificates. Not bad.
