Indonesia is next fucking level.

Javanese names used to commonly be mononyms, was only required that people have a surname in 2022.

In Bali, children are essentially numbered. First kid is called Wayan, Putu, Gede, or Ni Luh. Second kid is Made, Kadek, or Nengah. Third kid is Nyoman or Komang. Fourth kid is Ketut. Fifth kid? They go back to Wayan. Most of these names aren't gendered, either.

In a big company, there are often many people with the same name. some companies may add a numeric suffix to their name like abc1, abc2, abc3.

We usually don't use our real names for social media accounts

It's interesting how cultural differences can make some life algorithms hardly work in some countries. I sometimes use a method to find people from my past by googling their full name, switching to the image results, and spending a manageable amount of time scrolling through them until I find the person. I've successfully used this method several times. The images are usually related to job activities or social media profiles. However, from your description, this approach probably won't work in China for at least two reasons: too many raw results and few or no social media results.

UPDATE: a follow-up question. If in a big company two or more figures happen to have the same full name and need to be exposed publicly (on a site or promotional materials), are there any tricks for this?

Wow this is so rare, I can't recall any case like this.

But there are celebrities with exactly the same name, the media add a "big" or "little" prefix to their names according to age

From what I can tell, official documents rely on ID numbers, and for the social side, people can just come up with informal more unique names. But I'm not an expert.

A lot of names which are spelt differently in Chinese are translated to the same Latin spelling. So there’s a lot less conflict than it seems.

India is an interesting subject with so many Kumars and Prasads. They probably don't try to stand out with their name brand.

moslem naming is also not very different sometimes. lots of duplicate names like ahmed ahmed and mohammad mohammad. must be very frustrating! (it would be interesting to know how they manage it, since i do not know any of them personally.)
