The Legal Foundation: Law 15-04
Algeria’s electronic signature legal framework rests on Law No. 15-04 of February 1, 2015, which establishes general rules for electronic signatures and electronic certification. The law recognizes two tiers of electronic signatures: standard electronic signatures, which carry legal effect but face evidentiary limitations, and qualified electronic signatures, which receive full legal equivalence to handwritten signatures.
The distinction matters. A qualified electronic signature requires a qualified electronic certificate issued by a licensed certification authority, creation using a secure signature creation device, and a unique link to the signatory that provides identification and control. Only qualified signatures automatically satisfy legal requirements that traditionally demand handwritten signatures — including commercial contracts, notarial acts, and regulatory filings.
Standard electronic signatures, while not automatically equivalent, are not denied legal effect solely because they are electronic. Courts evaluate their reliability based on the method used, the identification of the signatory, and the integrity of the signed document.
The Certification Authority Framework
Under the Algerian system, electronic certification service providers must obtain a license from the postal and telecommunications regulatory authority (ARPCE). Licensed certification authorities issue the qualified electronic certificates that underpin qualified signatures. The licensing process requires compliance with a specification book that outlines operational standards, security requirements, and consumer protection obligations.
The certification authority must maintain the infrastructure to verify signature validity, manage certificate revocation lists, and provide timestamp services. This creates a trust chain: the regulatory authority licenses the certification provider, the provider issues certificates to organizations and individuals, and those certificates enable qualified signatures that courts recognize as equivalent to ink.
Algeria’s approach mirrors the European Union’s eIDAS regulation in structure, though with differences in technical standards and cross-border recognition. The EU framework has been operational since 2016 and has driven a mature market of trust service providers — a market that Algeria is now building domestically.
The 2025 Trust Services Law: Expanding the Framework
The Council of Ministers approved a draft Trust Services Law on November 2, 2025, which modernizes the 2015 legislation and aligns it with current technology. The new law extends legal recognition beyond signatures to include electronic seals (for organizations), electronic timestamps, electronic registered delivery services, and website authentication certificates.
The trust services framework grants electronic documents, signatures, seals, and timestamps the same legal validity as their physical counterparts. This expansion means a company can seal a contract with an organizational electronic seal, timestamp the signing moment with legal certainty, deliver the signed document via an electronic registered delivery service with proof of receipt, and authenticate its website identity through a qualified certificate.
Each of these trust services requires a licensed provider, extending the certification authority model across the full document lifecycle.

Where E-Signatures Change Business Operations
Banking and Financial Services
Algeria’s banking sector processes millions of paper-based transactions annually. Electronic signatures enable digital loan agreements, account opening documentation, and interbank contracts. Combined with Bank of Algeria Instruction 06-2025 governing payment service providers, electronic signatures create the legal backbone for digital financial services — from mobile wallet onboarding to digital lending contracts.
Real Estate and Notarial Acts
Property transactions in Algeria involve extensive paper documentation requiring notarial authentication. While the most sensitive notarial acts may still require in-person appearance, electronic signatures can accelerate preliminary agreements, due diligence documentation, and mortgage contracts. The Trust Services Law’s electronic seal provisions allow notarial chambers to authenticate documents digitally.
Government Procurement and E-Commerce
Algeria’s public procurement platform benefits from electronic signatures for bid submissions, contract awards, and vendor communications. For e-commerce — governed by Law 18-05 — electronic signatures provide legal certainty for purchase agreements, terms of service acceptance, and dispute resolution documentation.
Document Conservation Requirements
Algerian law imposes specific obligations for preserving electronically signed documents. Under Decree No. 16-142 of May 5, 2016, any party to an electronically signed document must ensure its conservation in a manner that preserves the document’s integrity and the validity of its electronic signature.
The conservation requirement means organizations cannot simply store a PDF — they must maintain the cryptographic signature data, the certificate chain, and timestamp information in a format that allows future verification. As certificates expire or certification authorities update their systems, long-term archival requires specific technical infrastructure that many Algerian organizations currently lack.
Adoption Challenges and the Path Forward
Three barriers slow adoption. First, the certification authority ecosystem is still developing. While the regulatory framework exists, the number of licensed providers offering qualified certificates remains limited compared to established markets. Organizations need accessible, affordable certificate services to adopt qualified signatures at scale.
Second, organizational readiness varies widely. Large banks, telecoms, and government agencies have the IT infrastructure to implement electronic signature workflows, but small and medium enterprises — which constitute 95% of Algeria’s business fabric — often lack digital document management systems.
Third, cultural acceptance takes time. Algerian business culture places high value on face-to-face agreements and physical documents with stamps and handwritten signatures. Shifting this expectation requires both legal certainty (which the framework provides) and practical demonstration that electronic signatures are reliable, secure, and enforceable.
The combination of Law 15-04, the Trust Services Law, and complementary regulations like Law 25-11 (data protection) creates a coherent digital legal infrastructure. The question is no longer whether electronic signatures are legal in Algeria — they are — but how quickly organizations and individuals adopt them.
Frequently Asked Questions
Are electronic signatures legally valid for all types of contracts in Algeria?
Qualified electronic signatures — those based on qualified certificates from licensed certification authorities — have the same legal effect as handwritten signatures for most contracts. However, certain transactions are excluded: gambling, alcoholic beverages, tobacco, and pharmaceutical products cannot be contracted electronically under Law 18-05. Additionally, some notarial acts may still require physical presence depending on the specific transaction and applicable regulations.
What is the difference between a standard and qualified electronic signature in Algeria?
A standard electronic signature uses any electronic method to indicate agreement — such as clicking “I accept” or typing a name. It has legal effect but may face evidentiary challenges in court. A qualified electronic signature requires a qualified certificate from a licensed certification authority, creation using a secure device, and a unique link to the signatory. Only qualified signatures automatically enjoy legal equivalence to handwritten signatures under Law 15-04.
How should businesses store electronically signed documents to meet Algerian legal requirements?
Under Decree 16-142, organizations must conserve electronically signed documents in a way that preserves both the document’s integrity and the electronic signature’s validity. This means storing the original document, the cryptographic signature data, the certificate chain, and timestamp information. Simple PDF storage is insufficient — organizations need archival systems that maintain signature verifiability even as certificates expire or technology evolves.
