How does an RP code look like?

I made bot that automatically tries codes from a .txt . I can also generate codes but I have to know how long they are and what is the Characterset(only uppercase and number?). SO how long they are and are they only uppercase and numbers/numbers only..etc?

10 characters

I mean the pre-paid cards that you can redeem in the "Codes" section, not in the purchase RP(it's not available at EUW).

Paysafe cards? They look like xxxx-xxxx-xxxx-xxxx .
The 'x' is a number.
