To complete renter verification, you need to submit a notarized USPS 1583 form (if you’re in the US) and two valid IDs.
Here's how you can upload your files:
Log in to your Anytime Mailbox account
Click "Complete Renter Verification"
If you’re applying for a US Mailbox, indicate if you have an SSN or not. On the next page, fill out the form, click Use Own Notary, and finally Upload Notarized USPS Form and IDs
If your mailbox is outside the US, proceed by clicking the Upload Supporting Documents button
