Is it OK you for generating random numbers instead of a sequential one which you're having right now ?

If you have used all the values between RU000001 and RU999999 and you can't change the length, or the RU prefix, then your only alternatives are to use other characters in place of the digits:
RUA00001 to RUA99999, then RUB00001, and so forth.
Get to RUZ99999 and you move to RUAA0001, and so on.

Or start with digits 1-z right away. However, given enough iterations, one time someone will complain about the barcode containing nasty words.
