The bridge between an ordinary general power of attorney - the kind drawn up for a parent's affairs, covering everything and naming nothing - and Iowa's vehicle record, which wants a specific car. The agent swears this, attaches it to the notarised general power, and the county treasurer can act. One affidavit per vehicle, and the department offers a straight alternative in its own instructions.
Written against 411020 (04-25), issued under Iowa Code s. 321.49 and 761 Iowa Admin. Code 400, supplement to a general power of attorney. If the owner is still able to sign, the shorter road is almost always better: Form 411021 names the vehicle, lists the powers as tick boxes, and is one document instead of two. This affidavit exists for the case where the general power already exists and the owner can no longer add to it.
Two documents, and they are not the same thing. Take the blank 411020 from the iowadot.forms.govos.com copy so you get the revision that is current today.
This is the actual 411020, rendered from the PDF the Iowa Department of Transportation, Motor Vehicle Division publishes and completed end to end: letterhead, every field, and the blocks at the foot.
The agent identifies themselves in three boxes at the top.
Watch out: The affiant is the attorney in fact. If you are the owner reading this, your name appears further down, as the principal.
Year, make and model on one line, then the VIN on its own.
Watch out: One vehicle per affidavit. Two cars under one general power means two of these, sworn separately.
The title number where there is one to give.
Watch out: There will not be one if the vehicle is coming into Iowa on out-of-state paper, which is why the department qualifies the line.
The affiant's printed full name, then the printed full name of the principal who granted the power.
Watch out: The principal's name has to match the general power and the front of the title. Two of the three matching is not enough.
The affiant signs under penalty of perjury and dates it.
Watch out: There is no notary block on this form - the notarisation is on the general power it is attached to, and the instructions require that power to be notarised.
The affidavit and the notarised general power go to the county treasurer together, as part of the transaction.
Watch out: Take the original power, not a copy. Iowa's rule allows a certified true copy, which is not the same as a photocopy.

Every line here was read off 411020 (04-25) itself — the PDF is here — and off the Iowa Department of Transportation, Motor Vehicle Division pages. This is plain-language help with a form, not legal advice, and where our wording and the agency's differ, theirs governs.
