Why e-Evidence matters
The 2026 compliance deadline
From 18 August 2026, all telecom operators in the EU must comply with the new e-Evidence Regulation (EU 2023/1543) and Directive (EU 2023/1544). These laws reshape how lawful data requests are managed across Europe.
New rules for cross-border lawful requests
Law enforcement authorities will be able to issue direct cross-border orders for subscriber or traffic data. Operators must respond within 10 days — or within 8 hours in urgent cases — and all requests must be handled through the EU’s e-CODEX platform. Failure to comply can lead to fines of up to 2% of global turnover.
The Compliance Challenge for Telecom Service Providers
STRICT DEADLINES AND EMERGENCY CASES
Manual workflows and overnight searches are no longer feasible. Meeting an 8-hour deadline demands automation, round-the-clock readiness, and seamless processes.
MANDATORY E-CODEX COMMUNICATION
Legacy methods such as email or local portals will be prohibited. Operators must establish secure connectivity to the e-CODEX platform for all lawful data exchanges.
LEGAL REPRESENTATIVE AND ACCOUNTABILITY
Each operator must appoint a designated legal representative (person or department) as the official point of contact for incoming EU requests. This role requires authority, resources, and integration across legal and security teams.
AUDITABILITY, GDPR AND DATA PROTECTION
Every action must be traceable, logged, and secure. Operators must balance e-Evidence obligations with GDPR compliance, ensuring only authorized data is disclosed.

Frequently Asked Questions (FAQ) on EU e-Evidence & e-CODEX Compliance
Your Questions, Answered.
We understand that data retention involves complex technical, legal, and security details. To provide clarity, we've gathered straightforward answers to the most common questions about the REX platform, its capabilities, and its compliance.
The primary challenge is the combination of extreme speed and mandatory technical integration. The regulation demands a response to emergency requests within just 8 hours, a deadline that is impossible to meet with traditional, manual processes. Furthermore, all communication must go through the secure e-CODEX platform, not email or portals. Most telecom operators' current workflows are fragmented across multiple systems (billing, network, CRM), creating bottlenecks that represent a direct and costly compliance risk.
Most existing data retention or lawful intercept (LI) systems were designed for national requirements, not for the specific demands of this new EU regulation. The e-Evidence framework introduces new complexities they weren't built for: the 8-hour emergency deadline, the cross-border nature of orders, and the mandatory, complex technical integration with the e-CODEX infrastructure. Attempting to "bolt on" an e-CODEX interface to a legacy system will not solve the underlying bottleneck — it cannot automate and accelerate the data consolidation needed to meet the 8-hour SLA.
e-CODEX is far more than a portal; it is a decentralized, secure digital infrastructure that acts as the mandatory channel for all cross-border judicial data exchange in the EU. For an operator, a compliant telecom data retention solution must integrate natively with this architecture. This involves using e-CODEX "Gateways" and "Connectors" to create a fully automated, end-to-end workflow — from securely receiving a European Production Order (EPO) to validating it, executing the query, and delivering the secure report back through the e-CODEX channel.
The only viable way is through automation. Meeting this deadline requires a fundamental shift from reactively searching for data to having it proactively prepared. An automated lawful request processing platform, like Subtonomy REX, continuously ingests and indexes data from all relevant sources (signaling, billing, IP records, CRM) before a request arrives. When an order is received via e-CODEX, the system can execute automated queries in seconds, compiling and delivering the report without human intervention, ensuring the 8-hour deadline is met every time
This is critical. Compliance requires integrity, not just speed. A modern platform must be "audit-proof by design". This is achieved with strict safeguards, such as mandatory search justification, where no query can be run without a valid, logged case number. Every action, from an authorized user's login to the final data delivery, must be recorded in a comprehensive, unalterable audit trail. This provides a defensible, step-by-step evidentiary chain for every request, proving to regulators that the data is accurate and was handled lawfully.
While August 2026 is the final implementation date, the timeline to readiness is long and complex. Key deadlines, like appointing a legal representative, are much earlier (February 2026). The procurement, integration, and testing of a new EU telecom data solution across multiple, complex data sources can take many months. Starting now is the only way to de-risk the project, run simulations, and ensure you have a robust, tested, and fully compliant platform operational before the deadline arrives and penalties of up to 2% of global turnover apply.
