The 209 area code sits at the heart of California’s Central Valley, a region known for its massive agricultural output, logistics hubs, and fast‑growing cities like Stockton, Modesto, Tracy, Merced, and Turlock. It also covers the gateway to Yosemite National Park, making 209 one of the most geographically diverse California area codes—linking farmland, freeways, and world‑class natural landmarks.

For residents, a 209 number means “Central Valley local.” For businesses, it is a powerful way to establish trust across this crucial corridor between the Bay Area and the Sierra Nevada.
What Is the 209 Area Code?
The 209 area code is a North American Numbering Plan (NANP) code serving California’s northern Central Valley and Sierra Foothills. It was created in 1958 as a split from the original 415 and 916 regions and is considered one of the older, established California area codes.
Key facts:

The New 350 Overlay
To ensure a continuing supply of Central Valley phone numbers, the California Public Utilities Commission (CPUC) approved an overlay for the 209 region.caaonline+3
What Is the 350 Area Code?
- 350 is an overlay area code that covers the same geographic territory as 209.
- It was introduced because 209 was projected to run out of available numbers by the end of 2022.localnewsmatters+2
- New phone numbers in the region may now be assigned 350 instead of 209, while existing 209 numbers remain unchanged.cpuc.ca+1
What It Means for Residents and Businesses
- No one loses their 209 number. Existing 209 subscribers keep their numbers indefinitely.caaonline+1
- 10‑digit dialing is mandatory. Calls within and between 209 and 350 require dialing area code + 7‑digit number (mobile callers often dial 10 digits or 1+10 digits).cpuc.ca+1
- From a local perspective, 209 and 350 are equally “Central Valley local”—they just represent different generations of numbering.
Is 209 Area Code a Scam?
The 209 area code itself is 100% legitimate and has served the region for decades. However, like many busy regional codes, 209 is frequently spoofed by scammers who want to appear as local California area codes to gain trust.allareacodes+1
Spoofing means a caller deliberately fakes the caller ID to show a 209 number, even when the call originates elsewhere.firstenergycorp+2
Common 209 Spoofing Scams

- Utility shut‑off scams
- Caller pretends to be from a local power, water, or gas company.

- Demands immediate payment via gift cards, prepaid cards, or peer‑to‑peer apps.
- Local government or “court” scams
- Caller claims to be from a county office, court, or law enforcement.
- Mentions fines, warrants, or missed jury duty, insisting you must pay right away.
- Generic “federal program” bill‑payment scams
- Promises a special program will pay your utility or other bills if you hand over personal info.
In many cases, these calls use 209 numbers to appear like they are coming from Stockton, Modesto, or nearby towns.
How to Handle Suspicious 209 Calls
To stay safe:
- Never trust caller ID alone
- Scammers can easily fake a 209 number; caller ID does not guarantee authenticity.firstenergycorp+1
- Do not share sensitive data
- Never give Social Security numbers, banking details, or one‑time codes to unsolicited callers.
- Hang up and verify independently
- If a caller claims to be a utility or local government office, hang up.
- Call back using the official number from your bill or the agency’s website.
- Be skeptical of pressure tactics
- Threats of immediate shut‑off, arrest, or “once‑in‑a‑lifetime offers” are classic scam markers.spokanecounty+2
