the U.S. and other countries “around the world”
meaning, for those of us living on other planets, we are completely safe … such a relief ! /s
It’s best to say around the world just so who ever is reading it doesn’t think it region specific.
For example, they could say “the U.S. and other countries in the western hemisphere.”
The other way works better since National Public Data is based in Florida and because of the name of the company. If it said “International” instead of “National” the readers would assume it is international data.
Based on the location, name of the company, and the breach mentioning social security numbers, stating the US first is the most logical.
