Hi, I have a concern regarding my plate number.

The retailer gave me 2 numbers,

in the paper, it was printed with : NNNNNN - with 6 ALL numbers
the other one that they mentioned that could also be my plate number is NAA-NNNNNN - it has 2 letters and 7 numbers.

I'm confused now. Is this the new policy of LTO? and which one should I use,
the retailer mentioned that I can use both.
