Area Code Overview
Area code 623 was created in 1999 as a split from 602, covering the West Valley of metropolitan Phoenix — Glendale, Peoria, Surprise, Goodyear, Avondale, Buckeye, Tolleson, and El Mirage. Overlay 326 was added in 2023. The West Valley is defined by rapid new home construction — communities like Surprise and Buckeye are among the fastest-growing cities in the United States, with tens of thousands of new housing starts in the past decade. Glendale hosts State Farm Stadium (Arizona Cardinals NFL) and Desert Diamond Arena (Arizona Coyotes arena, now under redevelopment). Peoria and Surprise are home to spring training complexes hosting eight Major League Baseball teams as part of the Cactus League.
Scam Patterns in 623
MLB Cactus League Spring Training Ticket Fraud
Eight of the 30 MLB teams hold spring training in Peoria and Surprise within 623 territory — the Seattle Mariners, San Diego Padres, Kansas City Royals, Texas Rangers, Chicago White Sox, Los Angeles Dodgers, Colorado Rockies, and Arizona Diamondbacks. Weekend games and inter-divisional matchups sell out quickly, particularly for popular teams. Scam texts from 623 numbers offer spring training tickets at face value for sold-out games — requiring Zelle or Venmo payment before tickets are provided. No tickets are delivered. The Arizona Attorney General's Sports and Event Fraud unit has specifically documented Cactus League ticket scams as a recurring seasonal pattern.
West Valley New Construction Earnest Money Fraud
623 territory's explosive homebuilder activity — with Taylor Morrison, Meritage Homes, and Lennar operating hundreds of active communities — has created a construction earnest money fraud pattern. Scam texts impersonate homebuilder sales agents or preferred title companies, claiming a buyer's home purchase contract requires an earnest money deposit to hold a lot or structural upgrade selection. The fraudulent wire instructions redirect deposits to scammer accounts before the buyer's builder rep discovers the switch. New home buyers in Surprise, Buckeye, and Goodyear are specifically targeted because of their high volume of active purchase contracts.
Arizona Department of Economic Security (DES) Benefits Fraud
The Arizona Department of Economic Security administers Unemployment Insurance, SNAP, and cash assistance programs that serve a significant portion of the West Valley's workforce. Scam texts from 623 numbers impersonate AZ DES claiming a recipient's benefit account is locked, an eligibility renewal is overdue, or an overpayment has been detected and must be repaid immediately via a provided link to avoid benefit termination. These messages exploit the genuine complexity and anxiety that surrounds public benefit renewal — especially for recipients who depend on SNAP or UI benefits for basic necessities.
VoIP and Spoofing Risk Assessment
Risk Level: MODERATE
623's West Valley communities range from working-class Avondale and Tolleson to the fast-growing middle-class suburbs of Surprise and Buckeye. The new construction earnest money fraud pattern carries among the highest per-victim losses in the Phoenix metro's fraud landscape, as new home deposits commonly range from $5,000 to $30,000. Cactus League ticket fraud is sharply seasonal (February–March) but generates high complaint volume during that window. DES benefits fraud preys on the West Valley's working families at their most financially vulnerable moments.
What To Do If You Receive a Text From a 623 Number
Step 1: Verify Cactus League ticket purchases through official channels. Buy spring training tickets directly at mlb.com, each team's official website, or in person at the ballpark box office. Any private seller requiring payment app transfer before delivering tickets is a significant risk.
Step 2: Look up the number. Search at Who Sent That Text Message to check for prior reports, especially for spring training ticket offers, homebuilder payment requests, or DES benefits alerts.
Step 3: Verify new home wire instructions by calling your builder's sales office directly. Use the phone number from your purchase contract — not a callback number in a text. Homebuilders do not change earnest money wire instructions by text. See our guide on how to identify real estate wire fraud.
Step 4: Report. Forward to 7726 (SPAM). Report sports ticket fraud to the Arizona AG at azag.gov. Report DES fraud to AZ DES at des.az.gov. File with the FTC at reportfraud.ftc.gov.
