When applying for higher studies abroad (WES evaluation, US/UK/Canada universities) or undergoing background checks with corporate employers (TCS, Infosys, Wipro, Accenture), candidates upload digital copies of their Class X, XII marksheets, or University Degree certificates downloaded from DigiLocker or the National Academic Depository (NAD).
Often, international credential evaluation agencies and corporate HRs flag digital certificates that show a yellow question mark (?) or "Signature Validity Unknown", asking students to obtain manual apostille or embassy attestation.
Academic boards like CBSE and universities sign certificates using digital tokens issued under the National Informatics Centre (NIC) Certifying Authority. International software like Adobe Acrobat and foreign admissions portals do not have the Indian CCA/NIC root certificates pre-loaded, resulting in an unvalidated signature alert.
VerifySign.in converts your digital academic document into a Long-Term Validation (LTV) PDF. The yellow question mark is replaced by an authentic green checkmark stamp containing the official certifying authority details and verification date.
Instant verification for CBSE, ICSE, state boards, and university certificates.
