Description
Dynamic Number Insertion (DNI) allows you to automatically replace phone numbers across your WordPress site based on the page URL. Perfect for businesses with multiple locations, marketing campaigns with unique tracking numbers, or any situation where you need different phone numbers on different pages.
The plugin intelligently detects various phone number formats and replaces them consistently throughout the entire page – including headers, footers, widgets, and content areas. It works seamlessly with your existing theme and plugins, requiring no code modifications.
Phone numbers are replaced before the page loads, ensuring compatibility with call tracking services like CallRail and other JavaScript-based tracking solutions.
Key Features:
✅ Automatic phone number format detection (handles parentheses, dashes, dots, spaces)
✅ URL-based replacement rules for precise targeting
✅ Works everywhere – headers, footers, widgets, menus, and content
✅ Compatible with page builders and themes
✅ No coding required – simple dashboard interface
✅ Preserves SEO and tracking scripts
✅ Lightweight and performance-optimized
Use Cases:

Yes! The plugin works at the output level, capturing and modifying the final HTML before it’s sent to the browser. This means it works with any theme or page builder.
Yes. The phone number replacement happens during PHP processing, before the page loads in the browser. This means JavaScript-based call tracking services can still function normally on top of the replaced numbers.
The plugin uses exact URL matching, and the most specific rule takes priority. Each URL can have one active rule at a time.
No. The plugin is highly optimized and uses efficient output buffering. The replacement process adds minimal overhead (typically less than a few milliseconds per page load).
