That map clarifies the layout. Now, let’s trace how 310 evolved over time.

History: From 1991 Split to Modern Overlay Challenges

310 split from 213 on November 2, 1991. This addressed phone demand in West and South LA.

In 1997, another split created 562 for southeast areas like Long Beach. This kept 310 focused on coastal zones.

By 2006, overlay 424 joined to prevent exhaustion. Protests delayed it due to 10-digit dialing costs. It was California’s first overlay under new rules.

In 2025, the FCC watches for shortages. No splits loom, but vanity numbers sell fast. This history shapes today’s use—know it to avoid old dialing habits.

Understanding the past helps with current rules. Next, dial right to skip fees.

Always use 10 digits for local calls within 310 or 424. Skip the “1” prefix unless calling outside.
