Scholastic published the book in New York in 2003. In Britain it first appeared from Chicken House, Frome, in 2006 under a different title, Gregor and the Rats of Underland, so British collectors should look for that title rather than the American one. The first UK issue is a paperback, ISBN 1904442420 (9781904442424); the British Library record gives Frome, Chicken House, 2006, and 258 pages, and Open Library and UK bookseller listings agree on 2006 and a softcover. A Chicken House issue dated 2007 carries ISBN 9781904442813. Scholastic later issued the book in Britain under the American title (for example ISBNs 9781407121130, 9781407137032 of 2013 and 9781407172583 of 2016); those are not the first UK edition.
We have not yet confirmed the issue points that tell this first impression from later ones. Until we do, compare your copy's title page and copyright page with the publisher, place and year above: any later printing or edition statement means it is not this one.
