When meeting someone for the first time, it is customary for Indians to ask you what your "good" name is. It could be our way of making a first interaction seem more polite and formal.

It could have also emerged form the Hindi phrase "Aap ka shubh naam kya hai?"

When meeting someone Indian for the first time, it is customary for them to ask you what your "good" name is.

It could be our way of making a first interaction seem more polite and formal, or could have been a literal translation from the Hindi phrase "Aapka shubh naam kya hai?" Alternatively, it may be a derivation from the Bengali custom of giving everyone a "shubh naam" (a good, or given, name) and a "daak naam" (a petname or nickname).
