Phone numbers and message content constitute personal data under GDPR. Implement ephemeral auto-purge retention routines and PII masking to stay compliant.
Under the European Union General Data Protection Regulation (GDPR), MSISDN phone numbers, IP addresses, and message contents are classified as Personally Identifiable Information (PII). Telephony platforms must enforce data minimization and strict retention limits.
1 Architectural Best Practices for Telecom GDPR Compliance
- Ephemeral Storage: Automatically purge SMS message bodies from production databases within 24 to 72 hours of delivery.
- Masking & Hashing: Store phone numbers as salted cryptographic hashes (e.g. SHA-256) for audit trails rather than raw plain-text digits.
- Right to Erasure: Build automated API endpoints that scrub user telecom logs upon receipt of an Article 17 erasure request.
