Notarize your USPS Form 1583 in minutes with Proof!
iPostal1 has partnered with Proof to offer a secure way to complete your USPS Form 1583 online, 24/7. See the instructions below, or if you have a pre-filled form, click to complete your notarization!

How it works

2. Provide proof of identity
Proof will ask you to upload two acceptable forms of ID (listed below) for identity verification and to validate the address on your USPS Form 1583.

3. Connect with a live notary
In seconds, Proof will connect you with a commissioned notary over a live video feed. The notary will confirm your identity, witness your signature, and assist you throughout the process.

4. Submit your documents
Once your notary meeting concludes, Proof will require a credit card payment before granting access to download your completed forms. Please be aware that iPostal1 does not receive a copy of your finalized documents automatically. To complete the process, you must submit your notarized Form 1583 and both forms of ID to iPostal1 by emailing iPostal1FormsSupport@Staples.com.
