This information is compiled from publicly available records and may include data for multiple individuals with similar names. Data may contain inaccuracies or be incomplete. This information should not be used for employment screening, tenant screening, credit decisions, or any purpose covered by the Fair Credit Reporting Act (FCRA). Always verify information independently before making any decisions.

How to Read This Report

This page aggregates publicly available records from government agencies, court systems, and official registries into a single report for William Rieflin. Because public records are indexed by name rather than by a unique identifier, the 43 results displayed here may include information belonging to multiple individuals who share the same name โ€” a common occurrence, especially for frequently appearing names. To determine which records belong to the person you are researching, compare the location, approximate age, and any associated details across entries. Records that share an address or overlapping timeframe are more likely to refer to the same individual.

What Each Data Category Means

Business and Professional Records

Business records are compiled from state Secretary of State filings, SEC EDGAR corporate disclosures, and professional networking data. When a person appears as an officer, director, or registered agent, it reflects a formal role filed with a government agency โ€” these are legal positions of responsibility, not informal job titles. Records sourced from professional profiles represent information that individuals have chosen to make publicly available about their career history, skills, and affiliations. Business entity registrations show current or historical standing with the state, but a listing does not guarantee the entity is still actively operating.

Campaign Finance Contributions

Federal election law requires the disclosure of political contributions exceeding $200 to any single committee in a calendar year. These records are filed with the Federal Election Commission (FEC) and include the donor's name, mailing address, employer, occupation, and the amount contributed. Contributions to state and local candidates are governed by each state's campaign finance laws, which may set different disclosure thresholds. The data shown here reflects what was reported in official filings and may include contributions made over the course of many election cycles, so the dates and amounts should be read in their historical context.

Vehicle Records

Vehicle ownership records are obtained through sources that comply with the Driver's Privacy Protection Act (DPPA), the federal law that governs who may access motor vehicle records and for what purposes. The records shown indicate vehicles that have been registered to this individual through state DMV systems. Vehicle data may include make, model, year, and VIN, and reflects registration information at the time the record was filed. Vehicles that have been sold, traded, or transferred may still appear until the registration is updated in the state's records.

Important Limitations

Public records may contain outdated information, data entry errors, or records that belong to a different person who shares the same name as the individual you are researching. Government agencies update their records on varying schedules, and the data shown here may not reflect the most recent changes. Information on this page is provided for informational purposes only and should not be used for employment screening, tenant screening, credit decisions, or any other purpose regulated by the Fair Credit Reporting Act (FCRA). Always verify critical details through the originating government agency or official registry.

Your Rights

If you are the person described in these records, you have rights regarding your personal data. Under laws including the California Consumer Privacy Act (CCPA) and similar state privacy statutes, you may request the deletion or correction of your personal information. To submit a removal request, visit our opt-out page. For a complete description of how we collect, use, and protect personal data, please review our privacy policy.
