Truecaller has sophisticated anti-fraud systems. They know about proxies. Here is how they fight back:
For peer-to-peer proxy to work, other Truecaller users must enable “Allow Proxy Verification” in their settings. Many users don’t know this exists, limiting coverage.
Instead of a proxy, use a virtual number service (like TextNow or Google Voice) that works in your target country. Forward that number to Truecaller. This bypasses the proxy layer entirely.
