There are three types of advanced searches: the Advanced 8871 search, the Advanced 8872 search, and the Combined 8871 and 8872 search. Advanced searches are limited to information available from electronically filed forms (not forms filed on paper). In all three advanced searches, you can search any or all fields contained on the electronically filed form (such as Name of Organization, EIN, Contact Name, Amount of Contribution, etc.) for criteria that you specify. The results will be limited by the date the information was made available, as the legal requirements and the reporting methods (paper or electronic filing) changed. To help you search, the advanced search pages indicate which information is available from which dates. Therefore, if you search fields across multiple date ranges, your search results will be limited to the most recent date range.
