How can Blinkit allow its delivery partners to use these kind of short names ?

what are you going to do with their name ?

Its not about allowing, its just taking the first name.

For this use-case, let's say the person's name is "K Srinivas"

Here K might be his father's name, so in order to show respect they just keep the initial letter along with their name and this is way too much common in South India

I hope this answers your question :)

Also I know a guy whose last name is just a single Alphabet. Even on aadhar and pan.

Even my last name is a single character, what's the issue with it ?

Let's stop assuming put some validations on those text fields in sign up form 👥️

I guess first name would have been captured here. Usually South indians have different nomenclature of naming these and name would be as pe aadhar details. Correct me if im wrong

Guess it's the mismatch between first and last name
