    "description": "Mail theft and check washing have surged since 2020 but remain largely invisible to people who have not been directly affected. Most Americans who learned about mail fraud in childhood think of it as a dated crime involving elderly targets; the modern version -- organized rings stealing USPS collection box deposits and washing checks -- is less widely known. No rigorous national survey isolates worry specifically about mailed-check fraud.\n",

Annual probability per household: 299,000 / 130,000,000 = 0.0023. Compounded over 59 adult years: 1 − (1 − 0.0023)^59 ≈ 0.127 ≈ 0.13. This is an upper-bound figure because (1) a single victim may file multiple complaints; and (2) FY2022 was near peak; FY2024 rates have declined with enforcement. Check fraud SARs (FinCEN data) provide a separate line of evidence: 680,000 check fraud SARs were filed in 2022 by financial institutions, roughly double the 350,000 in 2021. Not all check fraud is mail-related, but FinCEN specifically attributed the surge primarily to mail theft. Given under-reporting, the true victimization rate likely exceeds the complaint count.\n",

This upward trend continued into 2022, when the number of SARs related to check fraud reached over 680,000, nearly double from the previous year's amount of filings.

Used for context and trend evidence; the USPIS complaint count is used for the primary victimization estimate.\n",

Its SAR data is collected from thousands of financial institutions independently of USPIS law enforcement complaints.

The FinCEN SAR count (680,000 in 2022) is not directly comparable -- it measures financial institution reports, not individual victims. Both the USPIS complaint rate and FinCEN SARs are expected to decline from the 2022 peak as enforcement intensifies and physical check usage continues to fall. The estimate also conflates victimization (mail stolen) with successful fraud (check actually washed and cashed); not every mail theft incident results in financial loss. People who do not mail paper checks face near-zero risk from this specific fraud vector. Transition to electronic payments is the most effective personal mitigation.\n",
