Clarification needed about about Mobile Network Code in the data

Hi,

I have a confusion about the mobile network code. I am in Canada and according the OpenCelliD data following are the MNC :

[220, 720, 610, 490, 880, 500, 780, 320, 16410, 16420, 17500, 16422, 16384, 16436, 16414, 16462, 16408, 16390, 16418, 16430, 16472, 380, 620, 270, 660, 370, 72, 16634, 680, 64, 63, 1552, 1824, 520, 544, 1168, 1920, 86, 22, 61, 1632, 32, 130, 131]

On the other hand, according to official data, MNCs start from 100 and end at 998. I was wondering what does numbers such as 16462, 16408, 22, 61, 16384 etc. mean if they are not actual MNCs?
