My coauthor's university address has a typo in our published paper. What should I do? I recently got a paper published. One of the affiliations (for the 4th author, more precisely) is right but it has a misspelling in the address of his university. The right address is &quot;University X, Street y, no.1780&quot; but we published as &quot;University X, Street y, no.1879&quot;. Is it problematic enough to ask for a corrigendum if the other data about the affiliation (without the number) is right?
You should not do anything about this.  Nobody will use this information for anything.
Do not assume your coauthor was responsible.  It could be the journal.
