Basically, I am new to iOS development and for some reason, I need iTunes URL of my live app but while googled for the same getting more than one URL for the same APP is there any specific reason behind this by observation I think this might be for different countries.

It is for India's app store for WhatsApp
https://apps.apple.com/us/app/whatsapp-messenger/id310633997
It is for the USA's app store for WhatsApp
Also, available for other countries too such as China

Refer Internet Country Domains list for other countries
That's it. Nothing serious.
