- How long are eStamps valid? Once attached to an eSigned document, is it valid for life?
For unused stamp paper: Some states (e.g., Karnataka, Maharashtra) have a 6-month validity from the date of issuance — after that, you can't use it. Other states have no prescribed expiry — the stamp paper remains valid for more than 6 months.
Once attached to an eSigned document: Stamp paper is valid for life (provided it was valid when it was affixed).
