Phone Numbers Encoding

To encode contact phone numbers, please open your Anti-Spam plugin's settings (WordPress Dashboard → Settings → Anti-Spam by CleanTalk → Advanced settings) and check the Encode phone numbers option.

Here are the requirements for the number format:

• Must start with a "+" symbol.
• Must contain at least 8 digits and fewer than 13 digits.
• Spaces, parentheses, and dashes are allowed between digits.

Examples of valid formats:

• +1 (234) 567-8901
• +12345678901
• +12 34 5678901
• (234) 567-8910
• +49 30 1234567
• +49.30.1234567
• +1.775.333.3330

Phone numbers formatted correctly within an <a> tag with the "tel" property will also be encoded, for example:

<a href="tel:+11234567890">Call +1 (123) 456-7890</a>

Note: To encode a mnemonic phone number (a number containing letters like 1-800-EXAMPLE), please wrap it in a shortcode by following this guide.
