Tel-Linker US converts static US phone numbers into interactive tel: URI links, letting you choose exactly how you want to place your calls.

Designed for speed and privacy, this extension automatically identifies US-style phone numbers on web pages and wraps them in the standard tel: protocol. Instead of copying and pasting, a single tap or click hands the number off to your device's designated default dialer.
