Types of Mail That Cannot Be Forwarded by USPS

Several categories of mail will not follow you after you file a USPS change-of-address order. The main types of mail that cannot be forwarded by USPS are Marketing Mail (advertising circulars, coupons, and flyers), Package Services items like Media Mail, and any piece whose sender printed an endorsement telling USPS to return or discard it instead of forwarding. On top of that, First-Class Mail and periodicals only forward for a limited window before they, too, stop reaching your new address.

USPS Marketing Mail

Marketing Mail, formerly called Standard Mail or bulk mail, is the single largest category of mail that gets left behind. It covers store circulars, coupon books, credit card offers, and advertising flyers. Under a standard change-of-address order, USPS does not forward or return Marketing Mail unless the sender paid for an ancillary service endorsement requesting that treatment.1USPS. What is USPS Marketing Mail Most senders don’t pay for that endorsement. Most Marketing Mail addressed to your old home is simply discarded at the post office.

Package Services Mail

Package Services includes Media Mail, Bound Printed Matter, and Library Mail. These classes generally do not forward under a standard change-of-address order either.2USPS. Mail Forwarding Options If a friend ships you a box of books by Media Mail after you’ve moved, that package may never reach your new address. As with Marketing Mail, the sender would have to pay for a forwarding endorsement to override the default.

Mail Marked With a Sender Endorsement

The single biggest reason people are surprised when specific pieces don’t forward is a small line of text on the envelope. Senders can print ancillary service endorsements that override the normal forwarding rules for the mail’s class. Two of them block forwarding outright:

  • Return Service Requested. USPS returns the piece to the sender instead of forwarding it. First-Class Mail comes back at no charge; Marketing Mail costs the sender the single-piece First-Class or Priority Mail rate to get returned.
  • Change Service Requested. USPS discards the piece entirely and notifies the sender of your new address or the reason for non-delivery. You never see the original mailpiece.

Two other endorsements exist, Address Service Requested and Forwarding Service Requested, but those generally permit or facilitate forwarding rather than blocking it.3PostalPro. Ancillary Service Endorsements

One point worth clearing up: “Do Not Forward” is not an official USPS endorsement. If a sender writes or prints it on an envelope, USPS treats the piece as unendorsed and handles it under the default rules for its class. Banks, government agencies, and medical offices that actually want to prevent forwarding use “Return Service Requested” instead.

Mail That Has Aged Out of Forwarding

Even mail that qualifies for forwarding has a clock running from the day your change-of-address order takes effect:

  • First-Class Mail and Priority Mail forward for 12 months.
  • Periodicals (magazines and newspapers) forward for only 60 days.
  • Marketing Mail and Package Services do not forward at all under a standard order.

After those windows close, First-Class Mail sent to your old address is returned to the sender rather than delivered to you.2USPS. Mail Forwarding Options This is where most people run into trouble. If you haven’t updated your address directly with every important sender within that first year, letters start bouncing.

Government Agency and Election Mail

A common belief holds that the IRS, Social Security Administration, and state motor vehicle offices send mail USPS categorically won’t forward. That isn’t how it works. These agencies typically send First-Class Mail, which forwards normally for 12 months. What actually stops delivery is that many agencies print “Return Service Requested” on their envelopes, telling USPS to return the piece to them instead of forwarding it to you.4USPS. Mailing Your Tax Return The mail doesn’t reach you, but it’s the endorsement doing that, not a special government mail category.

Election mail is a particularly important case. Most election offices send ballots and voter registration cards with endorsements that trigger a return rather than forwarding. They do this on purpose: a forwarded ballot could indicate the voter no longer lives in the jurisdiction, which raises residency and eligibility questions. After moving, register with your new local election office directly rather than expecting a ballot to chase you across state or county lines.

Certified, Registered, and Insured Mail

You’ll see blanket claims that Certified Mail, Registered Mail, and Insured Mail “cannot be forwarded.” That overstates the problem. These items, called accountable mail because they require tracking, signatures, or both, are handled differently from regular letters, but they aren’t automatically returned to sender just because you’ve moved. Under standard forwarding, accountable mail is rerouted separately because it needs a scan or signature at delivery. The practical complication is that if delivery attempts fail at the new address, the piece eventually goes back to the sender. If you’re expecting certified or registered items around the time of a move, give the sender your new address directly so there’s no gap.

Mail Sent Through Private Carriers

UPS, FedEx, and DHL shipments are separate from USPS. Filing a USPS change-of-address order has no effect on packages moving through private carriers. Each company runs its own redirection tools, and none of them communicate with the USPS forwarding system. Update your shipping address with each online retailer individually after you move; a USPS forwarding order will not catch those packages.

Mail Sent to a Private Mailbox

If you rent a private mailbox at a UPS Store or another Commercial Mail Receiving Agency, USPS will not process a change-of-address order from that CMRA address to a different location. You can forward home mail to a CMRA, but not the other direction. When you close a CMRA mailbox, the CMRA itself is responsible for forwarding your mail for six months after termination.5USPS. Commercial Mail Receiving Agency (CMRA) That forwarding is done by the private business, not USPS, so reliability depends entirely on that store. Notify important senders directly rather than trusting the CMRA to catch everything.

What Happens to the Mail That Doesn’t Get Forwarded

Non-forwardable mail meets one of three fates depending on its class and endorsements:

  • Returned to sender. First-Class Mail that can’t be delivered or forwarded goes back with a notice that the recipient no longer lives at the address. If your forwarding order is still active, the sender may also receive your new address.
  • Discarded. Marketing Mail without an ancillary service endorsement is treated as waste. It never goes back to the sender and never reaches you.1USPS. What is USPS Marketing Mail
  • Returned with postage charges. Marketing Mail or Package Services bearing “Return Service Requested” is sent back to the sender, and the sender pays the single-piece First-Class or Priority Mail rate for the return.3PostalPro. Ancillary Service Endorsements

USPS labels all of this “Undeliverable-as-Addressed” mail.6PostalPro. Undeliverable-as-Addressed (UAA) Mail Statistics The bulk of it is Marketing Mail discarded because the sender didn’t pay for a return or forwarding endorsement. The most reliable way to keep important mail flowing after a move is to update your address directly with each sender who matters, well inside the 12-month window that First-Class forwarding gives you.
