Area Code Overview
Area code 818 was established in 1984 when California split the original 213 code to accommodate rapid population growth in the San Fernando Valley. It serves a sprawling suburban region north of the Hollywood Hills that includes Burbank, Glendale, North Hollywood, Studio City, Van Nuys, Encino, Sherman Oaks, Tarzana, Reseda, Chatsworth, Woodland Hills, and West Hills. Overlay code 747 was added in 2009 as 818 numbers were exhausted. The Valley — as locals call it — is home to Warner Bros., Walt Disney, Universal Studios, and NBC, creating a unique telecommunications profile: entertainment-industry VoIP lines are legitimately prevalent here, which scammers actively exploit for spoofing credibility.
Scam Patterns in 818
Contractor and Home Improvement Scams
The San Fernando Valley's large inventory of single-family homes makes 818 residents a disproportionate target for unlicensed contractor fraud. Following storm and wildfire events affecting parts of the Valley in recent years, the BBB Scam Tracker recorded a spike in texts from individuals claiming to offer debris cleanup, roof repair, or "FEMA assistance processing" in exchange for upfront payment. Legitimate contractors licensed in California do not solicit repairs via unsolicited text, and FEMA assistance is applied for through disasterassistance.gov — not through a third-party text.
Medicare Advantage Enrollment Scams
West Hills, Canoga Park, Tarzana, and other western Valley communities have above-average populations of residents over 65. Scam texts targeting these ZIP codes offer "free Medicare Advantage plan upgrades," "unused annual benefit consultations," or "new plan comparisons" — then harvest Social Security numbers and Medicare ID data. Medicare open enrollment has a defined annual period; unsolicited off-cycle texts about plan changes are a consistent scam indicator.
VoIP and Spoofing Risk Assessment
Risk Level: HIGH
818 numbers were exhausted within 25 years of the code's creation, largely due to the Valley's explosive growth and entertainment industry density. VoIP adoption is high: studios, production companies, and talent agencies throughout Burbank and Studio City routinely use VoIP lines. This legitimate prevalence makes spoofed 818 numbers harder to dismiss on sight alone. A text from an unknown 818 number may originate anywhere; the area code reflects where the number was originally assigned, not the sender's current location.

What To Do If You Receive a Text From an 818 Number
Step 1: Don't pay upfront for any service offered via text. Contractor repair offers and FEMA assistance offers both follow the same pattern — they request payment before any work is done or any eligibility is confirmed.
Step 2: Look up the number. Search it at Who Sent That Text Message to check the carrier, line type, and any prior spam reports.
Step 3: Verify contractors through official channels. California's Contractors State License Board (cslb.ca.gov) lets you verify any contractor's license before paying.
Step 4: Protect Medicare information. Medicare will not ask for your Medicare number or Social Security number via text. Report Medicare fraud to 1-800-MEDICARE or the HHS Office of Inspector General.
