>>History

The service area was originally contained in numbering plan area `F33f`_`[213`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Area_code_213]`_`f, which was split to create 818 in 1983, before splitting again in 1997.

Prior to October 2021, area code 626 had telephone numbers assigned for the `F33f`_`[central office code`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Central_office_code]`_`f 988. In 2020, `*988`* was designated nationwide as a dialing code for the `F33f`_`[National Suicide Prevention Lifeline`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=National_Suicide_Prevention_Lifeline]`_`f, which created a conflict for exchanges that permit `F33f`_`[seven-digit dialing`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Seven-digit_dialing]`_`f. This area code was therefore scheduled to transition to `F33f`_`[ten-digit dialing`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Ten-digit_dialing]`_`f by October 24, 2021.`:cite-ref-pl556-1-0[`F5bf`_`[1`#cite-note-pl556-1]`_`f]
