Rule 123.6
Official source text from the 17 November 2023 Rules release
A name sticker consists only of one or more words. A name sticker on a permanent or on a card in a zone other than the battlefield causes the word on that sticker to be added to the text of that object’s name. This is a text-changing effect. See rule 613.1c and rule 612, “Text-Changing Effects.”
