Why you can't mail quarterly packages directly to someone at CSP Solano — and what to do instead
Here's the part that surprises most people: you can't mail a quarterly package to someone at California State Prison, Solano yourself. CDCR doesn't allow family or friends to send these packages directly. Instead, quarterly packages must be purchased through private vendors that CDCR has authorized and approved. Why the restriction? It's about security — the vendor-only system cuts down on contraband and reduces the time staff spend searching packages from the public.
