The flexibility of number pools and routing rules lets you tailor the experience to your business model while maintaining strict control over fraud risk and compliance.

Precautions: Responsible Use and Compliance

Technology enables fast verification, but responsible use protects your customers and your brand. The precautions below help you deploy verification ethically, legally, and efficiently:

• Adhere to applicable laws and platform policies: use the verification service strictly for user onboarding, account recovery, fraud prevention, and security controls. Do not use it to circumvent rules or enable illicit activity.


• Manage data privacy proactively: minimize data collection, implement retention policies aligned with GDPR, and ensure secure data destruction when no longer needed.


• Communicate clearly with users: explain why verification is required and how numbers are used to build trust and protect accounts, reducing friction and abandonment.


• Apply rate limits and anomaly detection: prevent abuse by enforcing per-user or per-app limits and monitoring for suspicious sign-up patterns.


• Number hygiene and rotation: rotate numbers when appropriate to maintain deliverability and avoid blocklists, while ensuring a smooth experience for legitimate users.


• Prepare for outages with resilient design: implement failover numbers and queue-based retries to minimize verification delays during incidents.

Security, Privacy, and Compliance

Privacy and security aren’t add-ons; they’re baked into the architecture. We protect data in transit with TLS, enforce strict API access controls, and maintain transparent data handling practices that align with GDPR and Swedish data protection norms.
