Narrative:

I was working sector 21/22/30 combined. I was busy with numerous noise abatement departures off lax. Our procedure with mmzt ARTCC is that we don't manually hand off aircraft with them (automated hand offs are not available); they just terminate the aircraft and transfer communications. We then have the aircraft identify or assign a new code if required and re-identify them. A B737 checked in with me. I thought it was another aircraft off lax checking in and rogered that aircraft. There was a flight plan depicted on the uret but I was too busy to look at the uret. As I was trying to split off sector 21/22 ; sector 25 called asking who is that code approaching his boundary; at that point I tried to figure out who that aircraft was and saw the flight plan in the uret and was able to identify him. Recommendation; I believe we should be making manual hand offs with mmzt ARTCC instead of hoping they or us see the flight plan. I also believe that sector 21/22 should be split off of sector 30 earlier in the morning.

Title: ZLA Controller working combined sectors described a confused transfer/hand off from MMZT ARTCC that resulted in the aircraft fly a considerate distance into U.S. airspace before being positively identified.
