My landlord is asking my pan number, my rent is 17k per month, should I give him ?

Ask his pan number as well for your itr hra

You should ask his PAN instead

No, it can be misused. Ask for purpose and then ask his.

Ask his PAN number first, then he would stop asking about yours

Ask his Pan number also , for itr in HRA
He will try not give you but tell him I need to submit in company portal
