Thats because those are mostly developing countries which were late to the internet party, and are accessed mainly through mobile. Phone # could well be a replacement for email globally in the future, once all the younger generation grow up and rule the world.
Yep, but it will never replace email address as universal identifier until it is adopted by all.
In addition to that, reports show that the majority of Asian and African users access the internet via a shared device. Therefore phone number cannot be a universal identifier there as it generally identifies a group of people rather than in indivdual. This is why google and outlook accounts with SSO are still generally the most used identifying systems in the world.
Not really sure what you are saying here, it seems like you are a bit confused.
You were talking about phone numbers being used to access online services, and now you are posting links about the Indian governments Personal Identification number which is more akin to a National Insurance number in the UK or social security number in the US
> Do you think those folks in Asia and Africa sharing mobile devices have email accounts they can use instead?
Yes definitely. Huge numbers of people in these developing nmations share a single mobile device per family or household, yet they all have individual facebook and google accounts to communicate with the world. That is defintiely all controlled via email address, unless I have missed a feature of FAANG companies where you can sign up for accounts with a mobile phone number?
Most of Asia (and probably Africa) uses phone #.
