Andres,
Everyone is waiting in line because there are only 500 SB-100 numbers for the wole state and they will most likely be gone very quickly. When you first visit the DMV they should Reserve a number for you, then ony the CHP can issue a VIN number. After this and a visit to the smog referee to get your smog exempt sticker and if they require there, a safety check, you return to the DMV with all of this paper work and a bigger check at shich time they will issue you your permenent registration which you should receive in the mail in a few days/weeks. The CHP is the only ones that can issue or verify a VIN number for you under SB-100.
