Yes, Full KYC with Physical verification of documents is mandatory from 01-Sep. EKYC was valid only for 18 months since the date you did it. To check your KYC status, open Paytm app, click on Hamburger menu, then click on your name/number. The profile page opens. The KYC status will be shown there with validity.
