Probably because you're only registering domains within lax TLDs. Certain TLDs (like those under .uk, .cn, .jp, or .sg for example) requires more documents in theory - and at least with other domain name providers like Gandi, they asked for my ID and a letter from my company stating that I indeed was authorised to be a representative for that company, plus proof that the company exists (it's easy in the UK because it's already in a public database anyway, so we just send our company number and proof that we're that company), to verify that it is indeed me, authorised by my company, when registering at .uk (and similar arrangements for ccTLDs with similar requirements). Namecheap on the other hand... well, they just trust you, period.
