History of area code 213

Original NANP code. Downtown Los Angeles. Overlay 323 (1998).

The original 86 area codes were assigned by AT&T and Bell Labs in 1947 as part of the North American Numbering Plan. At the time, rotary-dial phones meant codes with lower digits (like 212 for NYC, 213 for LA, 312 for Chicago) were given to the largest cities because they took less time to dial. Today's area code assignments still reflect those early choices, even though touch-tone and cell phones made the original reason obsolete.

Is the 213 area code safe to answer?

Area code 213 itself is a normal geographic code with no elevated spam risk. That said, scammers can spoof any area code — including 213 — so if you don't recognize the full number, let it go to voicemail and verify the caller's identity before calling back.
