ACP programs don't forward every type of mail. Select your state and mail type to get a specific, accurate answer about what will and won't arrive through the forwarding system — and what to do about the gaps.
| Mail Type | Typically Forwarded? | Notes |
|---|---|---|
| First-class letters | ✅ Yes | Always forwarded — the core function of ACP |
| Certified / Registered mail | ✅ Yes | Forwarded and signature can be obtained at the state program office if needed |
| Priority Mail (USPS) | ✅ Most states | California and Washington explicitly include Priority Mail; verify with your state |
| Government notices | ✅ Yes | IRS, court notices, benefit statements — all first-class and forwarded |
| Express Mail / overnight | ⚠️ Varies | Some states forward; others cannot process overnight delivery to a P.O. box |
| UPS / FedEx packages | ❌ No | Carriers require a physical delivery address — P.O. boxes not accepted |
| Amazon / retail packages | ❌ No | Use a separate delivery address — trusted contact, UPS Store, or Amazon Hub locker |
| USPS packages / parcels | ⚠️ Varies | Flat-rate boxes and small parcels may be accepted; larger parcels typically not |
| Marketing / bulk mail | ❌ No | Standard-rate and nonprofit-rate mail not forwarded by most state programs |
| Magazine subscriptions | ❌ No | Periodical-rate mail not forwarded — use a separate subscription address |
| Legal service of process | ✅ Yes | Treated as valid service in ACP states; forwarded immediately |
