Let us suppose that the ה is the article.
Then we should look for כתובת in the dictionary.
If your dictionary is one that gives the entries in the unvowelized form (hasar haniqud), then you surely will find it: inscription, address.
But if your dictionary is one with entries in the usual vowelized form, then maybe you will not find it.
In its vowelized form this is a noun that belongs to patterns S-t: ptr S-t1884.A.
We thus get the inscription.
