Why doesn't apple provide Model info designated for specific country or carrier?

why would you ask that here? we're users just like you. If YOU don't know, what makes you think WE would?

If you're buying an iPhone new its easy to know which carrier it is locked to.

If you're buying second-hand it would be a question for the person you're buying from before you part with your money.

The model number is also on the back of the phone and in the 'About' section of Settings>General.

Yeah, but without a list of model numbers from Apple to look it up against for each carrier and country, it wouldn't be much use.

Because the idea of managing a hundred different models, simply because they were going to different carriers around the globe would be ridiculous. There are regional model numbers, that's enough to deal with. There is no physical difference between a phone sold in the UK, the US, or India. The only difference is in which phones are locked to which carriers which is all managed in software using a relatively easy to update database.

The "solution" to your quandry is buy only from authorized sources.

Becase there is no correlation between model numbers or serial numbers and the carrier a phone is locked to. Any model number can be locked to any carrier, or unlocked.

Those tables are not reliable. In the early days, when there were far fewer carriers, they were. They may be somewhat useful as the country codes can indicate where they originated and some countries do not sell unlocked phones at all, however, they are becoming fewer all the time. Even AT&T is now unlocking phones, so the indications that all phones of a specific model number sold by/for AT&T are no longer accurate.
