Scope and material limitation

What this answer covers

This guide covers OFAC's published update cadence for the Specially Designated Nationals List and where the dated files are published. It does not describe any specific designation action, and it does not evaluate any name against the list.

Methodology and limitations

How to interpret this answer

Methodology version: citation-answer/v1

  • The Last Updated value cited here is the value observed on the access date; it moves without a schedule.
  • This page describes cadence and publication mechanics only, not the contents of any list version.
  • Nothing on this page is a determination about any person or entity.

Frequently asked questions

Questions about this answer

Is the SDN List updated daily, weekly, or monthly?
None of those as a rule. OFAC states there is no predetermined timetable: updates land when designations are added or removed. Consumers who need currency track the download page's Last Updated stamp or OFAC's change notices rather than assuming a cycle.
Where is the official SDN List published?
On OFAC's sanctions-list data center at sanctionslist.ofac.treas.gov, which carries the complete list in XML, CSV, fixed-width, and PDF formats, plus data specifications and file signatures.
Does a list download settle whether a specific party is sanctioned?
No. A file reflects the list as of its Last Updated stamp, and a name match or absence in one file version is not an identity determination. Any conclusion should be scoped to the named file and date checked.

Integrated, with-data, and fresh-observation counts are separate. No platform-wide source-completeness count is published. Completeness is source-specific and must be evaluated against the named source's expected scope. State coverage is a separate jurisdiction measure.

Source authority is record-specific

Use the issuer named on the record.

Fonteum spans federal, state, and global public publishers. A source page or returned record identifies its issuer and dataset where that metadata is available. A platform registry count does not assign every page to one authority or establish loaded, fresh, or complete coverage.

Reproducible by design

Inspect the evidence each published figure actually supplies.

Source and date

Research pages expose the named public file and observation date where those fields are available. Source-file SHA-256 coverage is separate; facts do not currently link deterministically to signatures.

Available derivation

Studies with a retained release and committed derivation link the SQL or method used. Other studies state the evidence and reproduction limits they actually have.

Daily observations

Dated table row-count observations can detect local drift. They do not imply that an upstream publisher released or Fonteum ingested new data that day.
