Added more than once

Companies more than one list added.

Grouped by the first word of the name each list wrote. A vendor listing its own affiliates is not counted.

How we count

What makes a row.

Fewer rows than a raw diff, on purpose.

  • A name is on one daily reading of the vendor’s list and not on the one before, or the reverse.
  • Our reader’s own errors are set aside: a name re-spelled, or a name still on the page in other words.
  • The change is on our public change feed, which publishes 30 days after we read it.

Lists we cannot read are not counted. Where each vendor publishes says which pages those are, and why.

Common questions.

Where does this data come from?
From the vendors' own sub-processor pages. We read each one every day and keep a dated copy. A row here is a name that appeared on, or went from, the page between two readings.
Is a name on this list a new supplier?
It is a name the vendor's list gained. A vendor may have used the company before listing it, or may list an affiliate. We report what the page says, not why.
Can I use this data?
Yes. Cite Xither and link this page. The CSV holds every row with its source page and the link to the recorded change.

Not legal advice.

A name on a vendor’s list says who that vendor discloses. Whether it affects your agreements is a question for your counsel.
