PS Form 1000, Domestic or International Claim, is not required for insurance claims filed online. You may upload the evidence of insurance, evidence of value, and, if applicable, proof of damage or missing contents (described in this guide). Your claim may be delayed if you do not upload evidence of insurance or evidence of value.
Alternately, you can print the online claim form (PS Form 1000), attach the required evidence, and mail the information to the address on the form.
Note that you may be asked to provide proof of damage to a Post Office. The addressee must retain any damaged items and packaging until the claim is resolved.
