Reference material for the Register's search, exports, and bulk delivery.
Search
Search matches candidate names, committee names and numbers, contributor names, payee names, and FEC committee identifiers.
Exports
Tables export as CSV with every column shown plus the source filing identifier and load date. Research seats are limited to 10,000 rows per export; Professional and Institutional plans are unlimited.
Bulk delivery
Institutional plans receive the full ledger weekly as CSV or Parquet, partitioned by account type, with a manifest of the filings loaded since the previous delivery.
Identifiers
State committees are identified by their Division of Elections committee number. State candidates carry the Division of Elections account number. Federal candidates and committees carry their FEC identifiers. Donors and vendors resolved by the Register carry Register-assigned identifiers that are stable across refreshes.
