Third-party phone validation APIs charge per-lookup fees and introduce network lag on lead forms. The Framer International Phone Mask Premium Add-on validates mobile number length and national regex patterns 100% client-side without external API subscriptions.

Benefits of Local Validation in Framer

  • Sub-Millisecond Feedback: Immediate UI cues guide users to correct typos before submitting.
  • Zero Recurring SaaS Invoices: Flat annual licensing with unlimited visitors and submissions.
  • Universal Webhook Compatibility: Connects to Formspree, HubSpot, Make, or custom API endpoints cleanly.
