Have spam calls gotten worse for you in the past year?

Arizona residents filed 410,521 complaints about unwanted and spam calls between October 2020 and September 2025, a rate of 5,384.7 per 100,000 residents. The state's rate was about 35% above the average state rate and ranked 13th nationally in total complaints for the period.

Why it matters

Unwanted calls remain a persistent consumer problem, and the scale of complaints in Arizona shows how widespread the issue is for residents. Fiscal 2025 complaints rose again, signaling that the problem has not declined.

Arizona's 74,752 complaints in fiscal 2025 rose 29.8% from the prior year, though the total remained 47% below the fiscal 2021 peak of 141,601. The per-capita rate of 5,384.7 per 100,000 residents placed the state well above the national average.

The players

Federal Trade Commission

The FTC is the federal agency that enforces consumer protection laws and operates the National Do Not Call Registry, the source of the complaint data analyzed.

U.S. Census Bureau

The Census Bureau produces the official population estimates used to convert raw complaint counts into per-capita rates for each state.

The details

Researchers analyzed fiscal year 2025 data from the Federal Trade Commission's National Do Not Call Registry Data Book and compared complaint totals with 2025 U.S. Census Bureau population estimates. Arizona's complaints fell to a five-year low of 50,005 in fiscal 2023 before rising again, while Delaware recorded the nation's highest complaint rate at 5,736.4 per 100,000 residents.

Industry Impact

Since the National Do Not Call Registry launched in 2003, it has served as the main federal mechanism for consumers to block telemarketing calls. Arizona's five-year complaint totals show that unwanted calls still generate high volumes of consumer reports despite the registry's long existence.

Arizona residents who receive frequent unwanted calls can register numbers on the National Do Not Call Registry and report violations to the FTC. The continued high complaint volume suggests that consumers should use call-blocking tools on their phones.

The takeaway

Registering a phone number on the National Do Not Call Registry and reporting unwanted calls can reduce the volume of telemarketing calls residents receive. Using built-in phone call-blocking features adds another layer of protection.
