Complete USPS Form 1583 in 3 Minutes
Form 1583 is what lets us legally receive mail and packages on your behalf. It’s a quick ID check at our counter — or, if you can’t make it in, you can do it online from home. Either way it only takes a few minutes.
Why Form 1583 Is Required
The USPS regulates Commercial Mail Receiving Agencies (CMRAs) — businesses like ours that accept mail for other people. Before any CMRA can receive mail for you, USPS requires a completed USPS Form 1583. It is the document that authorizes In Out Parcel to receive mail and packages on your behalf.
It's a quick identity check — the same kind a bank does when you open an account. It confirms who you are and that the packages we hold are yours. Your information stays private and is never sold or shared, except where the law requires.
Required for everyone: Form 1583 is mandatory to receive mail or packages through us — you’ll need to complete it no matter which carrier delivers, not just for USPS.
Two Ways to Verify
Choose whichever works best for you — both complete the same USPS Form 1583.
Verify in Person
Bring your government-issued ID to the counter during staffed hours and a team member will check it and complete your Form 1583 with you on the spot. It’s free, and you walk out fully verified with 24/7 self-serve locker access.

Prefer to stay home? Sign in to the portal, upload a photo of your government-issued ID, and e-sign Form 1583 — no appointment and no printing. Once it is reviewed you get full self-serve locker access.
Verify to Keep Using Your Mailbox
Form 1583 is required to receive mail and packages with us — it’s a US postal rule for every mailbox, not an optional step. You’re welcome to collect your very first package while you get set up, but to continue service after that, you’ll need to complete it.
- Your first pickup is fine — collect it while you finish setting up.
- After that first pickup, Form 1583 must be completed to keep receiving and collecting packages.
- Verify once and you’re done — full 24/7 self-serve locker pickup, with no further checks.
It’s a one-time step that takes only a few minutes — do it online or at our counter, and your mailbox stays fully active with 24/7 self-serve pickup.
