Indonesia Electronic Signatures: PSrE Requirements

A PSrE is an electronic certification provider licensed by KOMDIGI to issue certified electronic signatures, and the framework ensures that signatures meet identity, integrity and non-repudiation standards.

Licensing comes first: a PSrE must obtain a licence from KOMDIGI (formerly Kominfo) covering identity-verification processes, cryptographic standards, certificate management and audit obligations. Before issuing a certified signature the PSrE must verify the signer's identity through eKYC — typically using KTP (national ID), passport or biometric verification — which is the core requirement for the legal presumption under ITE Law.

PSrE signatures then use PKI-based asymmetric cryptography, with each signature backed by a digital certificate that includes the signer's verified identity data, the certificate validity period and the PSrE's licensing information. Each signature also carries a trusted timestamp and an audit trail recording the signing event, IP address, device information and verification steps — the evidence package that makes the signature enforceable.

Foreign companies are not required to use a PSrE, but contracts signed without PSrE certification may face evidentiary challenges in Indonesian courts; for high-value or dispute-prone contracts, using a PSrE-certified signature on the Indonesian side is advisable.

Three further points shape cross-border use. Indonesia's Personal Data Protection Law (Law No. 27 of 2022) is now in force, so signing platforms that process Indonesian personal data must comply with consent, purpose-limitation and data-transfer requirements, and cross-border data transfer needs specific safeguards. On language, Indonesian law does not universally mandate Bahasa Indonesia for commercial contracts, but government contracts and certain regulated filings require it, so a bilingual (English/Bahasa) approach is safest for cross-border agreements. Some documents — particularly those involving land rights (HGB, hak milik) and notarial deeds — require physical notarisation and cannot be fully executed electronically: electronic signatures can be used for preliminary agreements, but the final registered document must go through a notary (PPAT).

The ITE Law establishes the framework through specific articles that distinguish uncertified from certified electronic signatures.

Article 11(1) provides that an electronic signature has legal effect and is admissible as evidence in court, but uncertified signatures carry no presumption of validity, so the burden of proof rests on the party relying on the signature. Article 11(2) states that a certified electronic signature — one verified by a licensed PSrE — has the same legal effect as a handwritten signature, creating a strong presumption that shifts the burden of proof to the challenging party. Article 12 defines electronic certificates as electronic records that identify the certificate holder and are signed by a certification service provider, and PSrE-issued certificates must meet the cryptographic standards and identity-verification requirements set by KOMDIGI. Government Regulation 71/2019 implements the ITE Law and classifies electronic systems into two tiers — public systems operated by government and private systems operated by private entities — and PSrE providers must register as private electronic system operators.

Only KOMDIGI-licensed PSrE providers can issue certified electronic signatures with the legal presumption that the ITE Law attaches to certified signatures.

PrivyID is one of Indonesia's most widely used PSrE providers, serving individual and corporate signers with eKYC using KTP and biometric checks followed by PKI-based signature issuance. The State Mint (PERURI) operates a PSrE service integrated with government identity systems, commonly used for government filings, state-owned enterprise contracts and regulated-industry transactions. Global e-signature platforms can operate in Indonesia by partnering with a local PSrE: the international platform handles the document workflow and user experience while the PSrE handles identity verification and cryptographic signature issuance, preserving the legal presumption that applies to certified signatures.

Indonesian employers implementing electronic signing must ensure PSrE compliance.

Choose a PSrE-certified provider: signatures from PSrE-certified providers carry the legal presumption that applies to certified signatures, so verify your provider's PSrE certification with the Ministry of Communication and Digital before deployment, since non-certified signatures are admissible but carry lower weight. Configure identity verification: Indonesian citizens can use Sistem ID, similar to Singpass in Singapore, and platforms that integrate with it offer a better signer experience and stronger identity proofing. Meet language requirements: employment contracts in Indonesia should be in Bahasa Indonesia (Law No. 24 of 2009), and if a bilingual contract is needed the Bahasa version prevails, so the platform must support Unicode in document content and signer names. Finally, handle data localisation: the PDP Law requires personal data to be stored in Indonesia under certain conditions, so confirm that your platform offers Indonesian data residency or that cross-border transfer mechanisms are in place for signing data.

eSign.AI supports Indonesian signing workflows through its confirmed Vinotek integration; the deployment must still verify Vinotek's role, the applicable registered PSrE service, the certificate product and the identity-verification process.

For a signature to be described as certified, confirm the registered PSrE involved, the certificate chain, the signer identity process and the current Komdigi status for the selected service. The signing UI is available in Bahasa Indonesia, contract content fully supports Indonesian diacritics and formatting, and the audit trail is generated in Bahasa and English to serve both local compliance and international employer needs. On data protection, eSign.AI captures data-processing consent as part of the signing flow, offers data residency options for Indonesian signing data, and provides data-subject access mechanisms for compliance with the PDP Law. Identity options in Indonesia continue to evolve: eSign.AI's current confirmed local integration is Vinotek, and any national digital-identity connection or additional PSrE integration should be published only after the production interface and provider status are confirmed.
