Haha,, I know this,,,,,,

I did trademark registration for 2 years before. .

The number written on the trademark acceptance notice is the category of the trademark you are applying for. . .

Trademarks are divided into 45 categories.

Categories 1-34 are the classification of goods

35-45 are the classification of services.

For example, if you want to register furniture, it will be in category 20,,,

If you want to open a specialty store, it will be in category 35,,,

Each major category is divided into many smaller categories, which are very detailed. . .
