Starting Sunday, Oct. 24, all phone calls in the 650 area code will require the 10-digit number, even if you’re calling another 650 number. Embarcadero Media file photo by Magali Gauthier.

Starting on Sunday, Oct. 24, all phone calls on the Peninsula — even local ones — will require the three-digit area code, the FCC announced. The 650 area code is one of 82 across the country making the switch.

In California, you may also need to dial 1 before the area code, according to the FCC.

The rollout of a new three-digit number to reach the National Suicide Prevention Lifeline is the reason behind the change. Last year, the FCC established 988 as the nationwide three-digit phone number for the service which will be available nationwide by July 16, 2022. It “will provide an easy to remember and easy to dial three-digit number to reach suicide prevention and mental health counselors, similar to 911 for emergencies and 311 for local government services,” the FCC said in a statement.

Callers needing help are advised to continue using the old number, 1-800-273-8255 (1-800-273-TALK) during the transition period.

According to the FCC, on and after Oct. 24, local calls dialed with only seven digits may not connect, and a recording will inform you that your call cannot be completed as dialed. If that happens, hang up and dial again using the area code and the seven-digit number.

A full list of affected area codes is online nationalnanpa.com.

  1. This is the 3rd article I’ve read about this and none coherently explain why a new 988 suicide prevention hotline means we must now dial 650 or 1-650 before even making local calls.
    And 1 day notice of this change? C’mon.

  2. If you can’t figure out “why” you have to dial an area code, it has nothing to do with the article and everything to do with your own reading comprehension. It’s very easy to understand.

  3. No problem!

    Good thing there’s not a shortage of digits, that is, we’re fortunate that the now-necessary extra digits aren’t all waiting to be off-loaded at the Ports of Los Angeles and Long Beach.

  4. In the link above in the article: “Reason behind the change”.

    There are 82 area codes in 35 states and one U.S. territory that currently use “988” as their local exchange and allow seven-digit dialing. A local exchange, also known as a central office code, is the first three numbers of a seven-digit telephone number. To prepare for implementation of a quick way to dial the National Suicide Prevention Lifeline – using only “988” to connect callers to the Lifeline – these area codes must transition to ten-digit dialing for all calls, including local calls.

  5. Rest assured 650 area codes will continue connect one to the local housing crisis. Sans affordable homes and still lot’s of discriminatory, historic “redlining” R1 zones.

  6. Why not just make the Suicide Hotline number to be FOUR numbers instead of inconveniencing us? 1234? That’s easy to remember. Wokeism.

  7. @ It
    Traditional phones don’t have any way to indicate that dialing is complete, so any valid number cannot contain another valid number as its initial digits. This issue is related to the data compression technique called Huffman coding — check it out!

  8. Isn’t this additional complexity for millions of people going to increase the suicide rate? Sometimes, truth is stranger than fiction when it comes to government. Irony comes to mind.

  9. Ok. I’m confused. Using my Verizon cell, I successfully connected to my partner downstairs without the 650 or a 1 but I’ve failed to reach a friend in 650 even after dialing with and without the area code and with and without a leading 1. When calling her landline, it just keeps ringing and her answering machine doesn’t pick up as usual.

    Please advise.

  10. Wow! Jennifer is being rather snotty with Felix. I, too, read the article several times and am still somewhat confused. The article says October 24 is the beginning and today is the 25th. First I’ve heard of it. Is today April Fool’s Day??

  11. In recent decades, the nuisance of having to dial 10 digits even for local calls in the US typically resulted from area-code “overlays,” multiple area codes in the same place (e.g., 669 added to 408 in southern Santa Clara County). In principle, it’s even possible to add such an overlapping area code without demanding 10-digit dialing, if the new code uses non-conflicting prefixes and the telco software has the necessary information to parse 7-digit numbers. It’s cheaper, though, to make the public do the work, dialing extra digits so the service providers have less to sort out.

    This new change is a variation of that standard situation: the new 3-digit dialing feature (988) coming next year conflicts with an existing local prefix here. In principle, a simple solution is to require dialing the area code, for local calls, only with the 988 prefix. In practice, that might confuse some people and besides — once again — it’s easier just to dump the burden on customers and make them dial more digits, even though fundamentally almost all local calling numbers are resolvable without them.
