Narrative:
En route from mex to san diego mexican controllers cleared us to 8000 ft. We were then handed off to socal approach, who gave us a vector. At 9000 ft socal transmitted that our assigned altitude was 10000 ft. Neither the captain or myself heard that our altitude assignment had changed during initial contact with socal.
