We check UK phone numbers against the official Telephone Preference Service (TPS) and Corporate Telephone Preference Service (CTPS) registers. Every check returns a clear result — registered or not — so your team knows exactly which numbers are eligible to call based on available data.
Every compliance check includes line type (mobile or landline), carrier identification, and geographic data for landlines. This helps you validate your calling data and plan campaigns more effectively, without paying for a separate data enrichment service.
TPSCheck is API-first. Our REST API returns JSON responses, supports batch checking of up to 100 numbers per request, and integrates into any CRM, dialler, or business application. Full documentation with code examples in cURL, PHP, Python, and JavaScript.
Audit logs, compliance risk scoring, and 28-day re-check tracking give you the evidence you need if the ICO ever asks. Export your records anytime for your own compliance files.
Most TPS checking tools were built over a decade ago. They offer clunky web forms, XML APIs, opaque pricing, and no developer documentation. We built TPSCheck because UK businesses deserve a modern, transparent compliance tool that works the way developers and compliance teams expect in 2026.
We publish our pricing on our website. We offer a free tier so you can evaluate the service properly. We do not require annual contracts. And we include phone intelligence data on every plan at no extra cost — because we believe compliance checking should come with useful data, not just a yes/no answer.
All data is processed and stored in the UK. We use TLS 1.2+ encryption in transit and AES-256 at rest. Our infrastructure is hosted on DigitalOcean.
Our pricing, terms of service, privacy policy, data processing agreement, and sub-processor list are all published on our website. No hidden fees, no surprises.
Growth, Business, and Enterprise plans include SLA guarantees with service credits. We publish our live status at status.tpscheck.uk.
We are registered with the ICO as a data controller and processor. We comply with the UK GDPR and the Data Protection Act 2018. We process personal data only as necessary to provide the service and in accordance with our published DPA.
TPSCheck is an independent commercial service operated by Visian Systems Limited. It is not affiliated with, endorsed by, or operated by the Information Commissioner's Office (ICO), TPS Limited, or the Data & Marketing Association (DMA).
