Are these RENAVAM numbers real?

No. They pass the mod-11 check digit so validators accept them, but they are random and not tied to any registered vehicle.

How many digits does a RENAVAM have?

Since 2013 it is standardized at 11 digits (10 base digits plus one check digit); older 9-digit codes are zero-padded to 11.

Can I use it for anything official?

No. These are fictional numbers for development and testing only; misuse is prohibited.
