It was split from [[area code 415]] on August 2, 1997, and includes most of [[San Mateo County, California|San Mateo County]] (except the northernmost portion), part of [[San Francisco]], and the northwestern portion of [[Santa Clara County, California|Santa Clara County]] including [[Palo Alto, California|Palo Alto]], [[Mountain View, California|Mountain View]], and [[Los Altos, California|Los Altos]].<br /> <br /> Prior to October 2021, area code 650 had telephone numbers assigned for the [[central office code]] 988. In 2020, &#039;&#039;988&#039;&#039; was designated nationwide as a dialing code for the [[National Suicide Prevention Lifeline]], which created a conflict for exchanges that permit [[seven-digit dialing]]. This area code was therefore scheduled to transition to [[ten-digit dialing]] by October 24, 2021.&lt;ref name=&quot;pl556&quot;&gt;{{cite web|url=https://nationalnanpa.com/pdf/PL_556.pdf|date=January 8, 2021|publisher=North American Numbering Plan Administrator |title=Transition to 10-digit dialing (for 988 as 3-digit access to National Suicide Prevention Hotline)|access-date=March 9, 2021}}&lt;/ref&gt;<br /> <br /> ==Service area==<br /> ===San Mateo County===<br /> {{div col|colwidth=20em}}<br /> *[[Atherton, California|Atherton]]<br /> *[[Belmont, California|Belmont]]<br /> *[[Broadmoor, California|Broadmoor]]<br /> *[[Burlingame, California|Burlingame]]<br /> *[[Colma, California|Colma]]<br /> *[[Daly City, California|Daly City]] (small portion in [[Area code 415|415]])<br /> *[[East Palo Alto, California|East Palo Alto]]<br /> *[[El Granada, California|El Granada]]<br /> *[[Emerald Lake Hills, California|Emerald Lake Hills]]<br /> *[[Foster City, California|Foster City]]<br /> *[[Half Moon Bay, California|Half Moon Bay]]<br /> *[[Highlands-Baywood Park, California|Highlands-Baywood Park]]<br /> *[[Hillsborough, California|Hillsborough]]<br /> *[[Kings Mountain, California|Kings Mountain]]<br /> *[[La Honda, California|La Honda]]<br /> *[[Ladera, California|Ladera]]<br /> *[[Loma Mar, California|Loma Mar]]<br /> *[[Los Trancos Woods, California|Los Trancos Woods]]<br /> *[[Menlo Park, California|Menlo Park]]<br /> *[[Middleton Tract, California|Middleton Tract]]<br /> *[[Millbrae, California|Millbrae]]<br /> *[[Montara, California|Montara]]<br /> *[[Moss Beach, California|Moss Beach]]<br /> *[[North Fair Oaks, California|North Fair Oaks]]<br /> *[[Pacifica, California|Pacifica]]<br /> *[[Pescadero, California|Pescadero]]<br /> *[[Portola Valley, California|Portola Valley]]<br /> *[[Princeton-by-the-Sea, California|Princeton-by-the-Sea]]<br /> *[[Redwood City, California|Redwood City]]<br /> *[[San Bruno, California|San Bruno]]<br /> *[[San Carlos, California|San Carlos]]<br /> *[[San Gregorio, California|San Gregorio]]<br /> *[[San Mateo, California|San Mateo]]<br /> *[[Sky Londa, California|Sky Londa]]<br /> *[[South San Francisco, California|South San Francisco]]<br /> *[[West Menlo Park, California|West Menlo Park]]<br /> *[[Woodside, California|Woodside]]<br /> {{div col end}}<br /> <br /> ===Santa Clara County===<br /> {{div col|colwidth=20em}}<br /> *[[Los Altos, California|Los Altos]]<br /> *[[Los Altos Hills, California|Los Altos Hills]]<br /> *[[Loyola, California|Loyola]]<br /> *[[Mountain View, California|Mountain View]]<br /> *[[Palo Alto, California|Palo Alto]]<br /> *[[Stanford, California|Stanford]]<br /> *[[Sunnyvale, California|Sunnyvale]] (western edge)<br /> {{div col end}}<br /> <br /> ===San Francisco County===<br /> *[[San Francisco, California|San Francisco]]<br /> <br /> ==References==<br /> {{Reflist}}<br /> <br /> ==External links==<br /> {{Area code footer|Map=CA}}<br /> * [https://web.archive.org/web/20090303160200/http://areacodedownload.com/650/index.html List of exchanges from AreaCodeDownload.com, 650 Area Code]<br /> <br /> {{Area code box | State = CA | This = 650<br /> | N = [[area codes 415 and 628|415/628]]<br /> | S = [[area codes 408 and 669|408/669]], [[area code 831|831]]<br /> | E = [[area codes 510 and 341|510/341]], [[area code 925|925]]<br /> | W = Pacific Ocean, [[area code 808|808]]<br /> | S1 = HI}}<br /> <br /> {{coord|37.5|-122.3|region:US-CA_type:adm2nd|display=title}}<br /> <br /> [[Category:Area codes in the United States|650]]<br /> [[Category:Area codes in California|650]]<br /> [[Category:Northern California]]<br /> [[Category:1997 introductions]]</div>
