If you are looking for the location of Area Code 627, you may find conflicting or outdated information. This is because Area Code 627 is currently unassigned or reserved in the North American Numbering Plan (NANP), meaning it is not actively being used for phone service.
However, the code was historically created for a specific region of Northern California as a relief effort for the existing 707 area code. Therefore, if you receive a call from a number labeled (627) XXX-XXXX, it is most likely a spoofed number or a number reserved for future use.
This article details the history of Area Code 627, its intended location, and the actions you should take if you receive a call from this unusual prefix.
The History of Area Code 627
The 627 area code was slated to serve the northwestern region of California, specifically areas currently covered by the popular 707 area code.
Intended Location
- Location: Northern California
- Original Purpose: Created as part of a geographic split of the 707 area code.
- Major Cities (Intended): Portions of Sonoma and Napa counties, including the Santa Rosa area.
- Time Zone: Pacific Time Zone (PT).
Status: Unassigned/Reserved
While the code was approved and plans for its implementation were set in the early 2000s, the California Public Utilities Commission (CPUC) eventually opted for an overlay relief plan instead of a geographic split.
- Result: The need for 627 was initially postponed, and the 707 area has since been subject to other relief methods. The 627 code remains within the inventory of reserved NANP codes that could be activated for use in California or elsewhere in the future.
Why You Might Receive a Call from (627) XXX-XXXX
Since Area Code 627 is not in active service, an unexpected call from a number using this prefix should be approached with caution.
- Telemarketer or Scammer Spoofing
The most common reason for receiving a call from an unassigned or inactive area code is caller ID spoofing.
- The Intent: Scammers and robocallers frequently use software to display random or unassigned numbers to bypass spam filters and trick you into answering. A number from an inactive area code may be a strong indicator of an illegitimate call.
- Action: If you do not recognize the number, do not answer it and do not call it back.
- VoIP Test or Outbound Service
In rare cases, Voice over Internet Protocol (VoIP) providers may use unassigned codes for internal testing or generic outbound dialing, but this should not be a standard practice.
Actionable Steps for Handling Calls from 627
Since Area Code 627 is currently unassigned, the risk of fraud or unwanted solicitation is high.
- Do Not Answer: If the call is important, the caller will leave a legitimate voicemail message.
- Block the Number: If you receive multiple calls from the 627 code, block the number immediately using your phone’s settings or a carrier-provided security app.
- Report the Call: Report the suspicious number to your mobile carrier (AT&T, Verizon, T-Mobile, etc.), as this helps them update their spam databases.
