Can’t type in a PDF form?

Short answer. Either the PDF has no fillable fields (it is a flat scan or printout), the field is read-only on purpose, the form is XFA-only, or the file is restricted. The inspector lists every field with its flags so you can tell which.

Causes and fixes

  1. 1
    No fields at allThe PDF is a flat document; there is nothing to type into.
    Add text anywhere
  2. 2
    Read-only fields, by designBarcodes, values copied from another field and signature boxes are often locked deliberately on official forms.

  3. 3
    XFA-only formThe fields exist only in Adobe’s XFA layer.

  4. 4
    Encrypted with editing restrictionsThe file opens without a password but restricts changes.

What is going on

A PDF only has typeable boxes if its author added form fields. A scanned page, or a form printed to PDF, has the lines and labels but no fields, and no viewer can make you type into it. You can still place text on such a page, which works well for simple forms.

If the form does have fields, some may be read-only on purpose. On USCIS forms, for example, the identification number shown at the top of each page is filled automatically from the first page, barcode boxes are generated by the form, and signature boxes are meant to be signed by hand on paper. Clearing those locks would let the copies disagree, so it is better to fill the source field and let the form do the rest.

Two other causes are less obvious. An XFA-only form keeps its fields in an XML layer that only Adobe software renders. And an encrypted file can open normally but forbid filling; if it is yours, or you were given the password, you can save an unrestricted copy. The inspector above shows each field’s name, type, page and flags, which usually makes the reason obvious in a few seconds. USCIS also asks typed mail filings to use Courier New 10 point bold [1].
