Strengthening Network Data Integrity for Telecom Operators with Acudo

A major UK telecommunications provider needed a solution to validate tens of millions of subscriber phone numbers sourced from SIM activations, number porting events, onboarding journeys, fraud checks, and partner resellers.

Their goal? To maintain an accurate, unified view of subscriber data across their entire network, improving routing decisions, reducing undelivered traffic, and meeting strict regulatory requirements such as Ofcom and GDPR.

Telecommunications providers face three major challenges when maintaining accurate subscriber records:

1. High data volatility

Customers port their numbers, switch networks, churn, or re-activate lines frequently. This makes subscriber data particularly prone to rapid decay, routing inconsistencies, and service delivery issues.

2. Real-time decision pressure

Subscriber numbers need to be validated instantly during onboarding, SIM registration, or partner integrations, without adding friction or slowing down automated workflows.

3. Complex, multi-system infrastructure

Subscriber records are often distributed across billing platforms, CRM systems, provisioning software, routing databases, and reseller portals, making unified validation difficult.

Additionally, even telecom providers themselves often lack the deep signalling visibility required to reliably confirm whether a number is live, reachable, or ported, making traditional tools inconsistent or overly technical.

Acudo integrates seamlessly with telecom systems through both real-time APIs and bulk dataset cleansing tools. This provides operators with a continuous, accurate view of their subscriber base.

Telecom providers use Acudo to:

• Validate subscriber numbers instantly during activation, SIM registration, number porting, or reseller onboarding.
• Automate large-scale cleansing of customer databases, routing tables, and historical subscriber records.
• Standardise signalling outputs to clearly indicate whether a number is active, inactive, unreachable, or recently ported.
• Feed reliable data into billing, provisioning, marketing, and compliance systems across the business.

This hybrid model ensures telecom operators maintain network-wide data integrity, reducing operational noise and enhancing customer experience across every channel.

• High-speed APIs built for telecom workloads, capable of handling constant, large-volume requests.
• Precision signalling insights with clear, standardised outputs suitable for operations, billing, and support teams.
• Multi-region and multi-team access controls for distributed telecom operations.
• Custom identifiers for tracking reseller traffic, porting activities, or partner usage.
• Optional advanced features such as disposable number detection and ported date verification.

For existing subscriber datasets, Acudo’s bulk upload portal enables:

• High-volume data uploads across CSV, XLSX and partner-formatted files.
• Parallel processing of millions of subscriber records with consistent performance.
• Scheduled, paused, or resumed uploads — ideal for network maintenance windows.
• Full data integrity, with results aligned to original subscriber entries.
• Real-time progress dashboards and downloadable analytics reports for operational teams.

1. Improved subscriber data accuracy

Telecom operators validating millions of subscriber numbers typically identify 10–20% inactive or unreachable numbers, significantly improving routing reliability and customer contactability.

2. Reduced OPEX and technical overhead

Removing unreachable or deactivated numbers reduces wasted SMS termination costs, failed call attempts, unnecessary support tickets, and incorrect routing events.

3. Fraud and risk mitigation

Accurate number status checks help reduce SIM swap fraud, fake signups, and invalid reseller activations.

4. Enhanced customer experience

Real-time validation ensures correct numbers at signup, preventing downstream issues in provisioning, authentication, and communications.

5. Stronger network intelligence

Acudo provides operators with a single, authoritative data layer that enhances routing decisions, marketing segmentation, and capacity planning.

• Global coverage: Reliable validation from over 220 mobile operators across all regions.
• Telco-grade scalability: Built to handle continuous, high-volume telecom traffic.
