@ Ramilya18, it is an Id of P.c. almost certainly; the order of the numbers corresponds. You try swapping the order of the digits. It CANNOT be a Geopostcards (there is no one from Moldova and the number is too large anyway). If you can't, go to https://www.postcrossing.com/receive/unknown and ask them for help (write in English or Portuguese, otherwise they won't answer you).
Greetings
@ Ramilya18, if you wrote in English, maybe more members could help you.
Here on Geo, Italy which has the most exchanges is at around two thousand eight hundred.

It is a P.c. Id (maybe with some errors); on P.c. the MD is at about seventy-five thousand
Я не корректно написала MD-75189
Я на трех сайтах, один только по России, там другой Id, международный, но там код из 8 цифр, и вот этот, короткий код только тут.
