What country does the passport number TG, TK and MZ begin with? Followed by seven digits.

The beginning of a passport number usually represents the nationality of the holder or the code of the country where the passport is issued, but not all countries follow the same rules. As far as I know, the following are the initials and their meanings of passport numbers in some countries/regions:

TG: Togolese passport

TK: Turkmen passport

MZ: Mozambican passport

Please note that this is only an example of some countries/regions and may change in the future. If you want to determine the source of a specific passport number, please consult the consulate or passport office of the relevant country.
