A full day's index of the official gazette

This tool assembles a complete day of Mexico's Diario Oficial de la Federación. Each publication comes back with its id, the heading exactly as printed, the edition (morning, evening or extraordinary), the section, the first and last page, the issuing branch (executive, legislative, judiciary, autonomous bodies, judicial and general notices, public tenders) and the responsible agency, plus flags telling you whether that entry has retrievable text and a link to its official scanned page. A normal business day carries over a hundred entries, so this is how you check in one pass whether a reform, an official standard (NOM), a Supreme Court agreement or a supplier debarment was published. If the date fell on a weekend or a statutory holiday, the result says so explicitly instead of returning an unexplained empty list.

  • The day's index

    Every publication with its id, heading, morning, evening or extraordinary edition, section and pages.

  • Who published it

    The issuing branch and responsible agency for each entry, so you can separate the executive, the judiciary, autonomous bodies and notices.

  • What you can open

    Whether the gazette ran that day, how many entries it carried and which ones have retrievable text or a PDF.

Common questions

From the Diario Oficial de la Federación, the Mexican state's official gazette. Croma queries the DOF and returns the day's index as separate fields, ready to review or export.

Yes, it is free and needs no account. There is only a cap on lookups per hour from the same connection to prevent abuse, and one date per lookup. For daily monitoring, use the Croma API.

Because the gazette did not run that day: the DOF is not published on Saturdays, Sundays or statutory holidays, and the result says so explicitly. Enter the date as yyyy-mm-dd; the index reaches back to 1917, and machine-readable text starts with the 1973 volume.

Here you get the index with each entry's id. With that id you open the full text in the DOF publication tool. Entries flagged as having no text were published as an image only and carry just their record and the official link.
