USPS accountable mail is the group of Postal Service options that require a signature at delivery and stay tracked from the moment a clerk accepts the piece until someone signs for it. The category covers Certified Mail, Registered Mail, Priority Mail Express, Collect on Delivery, any item insured for more than $500, and Signature Confirmation. Each of these creates a verified delivery record, which is what matters when a court deadline, an insurance claim, or a compliance rule turns on proof that a document or package actually reached the recipient.
Which Services Qualify
Section 503 of the Domestic Mail Manual governs the extra services that create an accountable chain of custody.1Postal Explorer. Domestic Mail Manual 503 – Extra Services The right choice depends on what you’re sending and what proof you’ll need later.
- Certified Mail is the standard choice for legal documents and notices. You get a mailing receipt and an electronic delivery record with the recipient’s signature. It’s available only on First-Class Mail and Priority Mail, and it does not include insurance.2United States Postal Service. Certified Mail – The Basics
- Registered Mail is the highest-security option. Every handoff between postal employees is logged, and items can be insured up to $50,000. Use it for irreplaceable documents, jewelry, and other high-value shipments.3United States Postal Service. Insurance and Extra Services
- Priority Mail Express gives overnight or two-day delivery with tracking and a delivery signature built in.
- Collect on Delivery (COD) has the carrier collect payment from the recipient before releasing the package, then remit the funds to you.
- Insured Mail over $500 automatically includes a delivery scan and signature record once the declared value crosses that threshold.
- Signature Confirmation is a lighter alternative to Certified Mail. It captures a signature and tracking but does not offer a mailing receipt or return receipt. It runs on Priority Mail, USPS Ground Advantage, and Package Services.
Every accountable piece carries a unique tracking barcode scanned at each handoff, and that barcode links to real-time location data through the final signature. The signature requirement is what separates accountable mail from standard delivery, where a carrier can leave a package without anyone acknowledging receipt.
What It Costs in 2026
Accountable service fees ride on top of regular postage for the mail class. A Certified letter costs the First-Class postage plus the $5.30 Certified fee, plus any add-ons. The figures below are effective January 2026.4United States Postal Service. Notice 123 – January 2026 Price Change
- Certified Mail: $5.30 per item
- Certified Mail Restricted Delivery: $13.70
- Certified Mail Adult Signature Required: $13.70
- Signature Confirmation (retail): $4.95
- Signature Confirmation (electronic/commercial): $3.95
- Registered Mail ($0 declared value): $19.70
- Registered Mail ($100.01–$500): $23.50
- Registered Mail ($500.01–$1,000): $26.40
- Return Receipt (hard copy, PS Form 3811): $4.40
- Return Receipt (electronic): $2.82
- Package Intercept: $19.45
Registered Mail fees scale with declared value and top out at $168.50 for items worth more than $50,000. There are no volume discounts on Certified Mail; the $5.30 fee is flat no matter how many pieces you send. The electronic Return Receipt costs about two-thirds of the hard-copy version and provides the same delivery proof by PDF.
Sending It: Forms and the Counter Rule
You cannot drop accountable mail into a collection box. It has to be handed to a postal clerk, who scans the barcode to start the tracking sequence and verifies your forms are filled out correctly. For Registered Mail, the clerk also applies postmarks across the envelope’s seams so any tampering will show.
The forms depend on the service:
- PS Form 3800 is the green-and-white Certified Mail receipt that carries the tracking barcode, addressing block, and checkboxes for Return Receipt or Restricted Delivery.5United States Postal Service. PS Form 3800 – Certified Mail Receipt
- PS Form 3806 is the Registered Mail receipt, which records the declared value and both parties’ full names and addresses.6United States Postal Service. PS Form 3806 – Registered Mail Receipt
- PS Form 3877 is a firm mailing book that lets you list many accountable pieces on one manifest instead of processing them individually.
- PS Form 3811 is the green Return Receipt card the recipient signs and mails back to you as physical proof of delivery.
When the clerk finishes, keep the receipt (or the detachable portion of your form). It is your proof of mailing and the document you’ll need to file an insurance claim or to show a court that you sent something on a specific date.
Receiving It: ID and Signature Rules
A carrier will not release accountable mail without checking ID. Under DMM Section 608.10.3, the recipient must present a current government-issued photo ID. Acceptable forms include a state driver’s license, a non-driver ID card, a U.S. passport or passport card, a military ID, a permanent resident card, tribal identification, and foreign passports, among others.7United States Postal Service. Domestic Mail Manual 608 – Identification Requirements Corporate and U.S. university IDs are accepted for some services but not all.
After ID is confirmed, the recipient signs on a handheld device or paper form. An adult household member or authorized agent at the delivery address can generally sign for standard accountable mail on the addressee’s behalf.
Restricted Delivery is the exception. When the sender pays for it, only the specific person named on the mailpiece (or a formally authorized agent) can sign, and the addressee must be an individual rather than a business name. This is the service lawyers and agencies use when they need to prove that a particular person received a document, not just that it arrived at a household.
Carriers may not leave accountable mail in mailboxes, on porches, or with minors. If nobody eligible is home, the carrier leaves a notice and takes the item back to the post office.
Signing Electronically Without Being Home
USPS Electronic Signature Online (eSOL) lets you authorize delivery of certain signature-required packages through your Informed Delivery account, so the carrier can leave the item at your door instead of hauling it back.8United States Postal Service. USPS Electronic Signature Online
The catch is scope. eSOL covers Priority Mail Express, Signature Confirmation, and items insured over $500. Certified Mail and Registered Mail are not eligible. You also need a personal Informed Delivery account (business accounts don’t qualify) and must pass identity verification before enrolling.
Timing matters too. You have to apply the electronic signature before the item receives an “out for delivery” or “arrival at unit” scan. Once either scan hits, eSOL disappears and you’re back to signing in person or scheduling a redelivery. Commercial shippers can also block eSOL on their packages, so the option isn’t guaranteed even for eligible mail classes.
If You Miss the Delivery
When nobody is home to sign, the carrier leaves PS Form 3849 (“Sorry We Missed You”) with the tracking number and instructions. You have two options: schedule a redelivery or pick up the item at the post office listed on the slip.
For redelivery, go to usps.com/redelivery or call the number on the form. Online requests submitted by 2:00 a.m. Central Time, Monday through Saturday, qualify for same-day redelivery; requests after that cutoff go out the next delivery day.9United States Postal Service. Schedule a Redelivery To pick up in person, bring your photo ID and the slip to the post office named on the notice.
Don’t wait too long. Certified Mail is held at the post office for 15 days and returned to the sender on the 16th. Priority Mail Express items also have a 15-day hold. Registered Mail and other accountable items may be held longer depending on service and circumstances, but 15 days from the first delivery attempt is the safe assumption. Once the holding period expires, the item goes back to the sender as undeliverable.
Pulling It Back or Redirecting
If you’ve already mailed an accountable item and need to stop it, USPS Package Intercept can redirect the piece before delivery. The service costs $19.45 and either returns the item to you or holds it at the destination post office for pickup.
Most accountable mail classes with a tracking barcode qualify, including Priority Mail Express and Priority Mail. Registered Mail can be intercepted, but only back to the sender: you write “Withdrawn” on the Registered Mail receipt, sign it, and surrender it at a post office.10United States Postal Service. USPS Package Intercept – The Basics
COD Hold for Pickup items, anything addressed to an international or APO/FPO/DPO destination, and mailpieces containing hazardous materials are not eligible. The item also has to still be in transit; once delivered or scanned as a final delivery attempt, intercept is no longer available.
Filing a Claim for Loss or Damage
If an insured or registered item arrives damaged, has missing contents, or never shows up, you can file an indemnity claim with USPS. The filing window depends on the service and the problem. Damage and missing-contents claims should be filed immediately, with an outer deadline of 60 days from the mailing date. Loss claims require a minimum wait to allow for delayed delivery, then must still be filed within 60 days:11Postal Explorer. Domestic Mail Manual 609 – Filing Indemnity Claims for Loss or Damage
- Priority Mail Express: no sooner than 7 days, no later than 60
- Registered Mail: no sooner than 15 days, no later than 60
- Insured Mail and COD: no sooner than 15 days, no later than 60
- APO/FPO/DPO destinations: longer windows apply, up to one year for surface-only insured mail
You’ll need proof of insurance and proof of value. Proof of insurance means your original mailing receipt, the outer packaging showing the insurance label, or a printout of your online shipping label. Proof of value means a sales receipt, invoice, credit card statement, or appraisal from a reputable dealer.12United States Postal Service. Domestic Claims – The Basics For damage claims, photograph the damage and keep all packaging. USPS may ask to inspect the item at your local post office, and failing to produce it triggers an automatic denial.
If your claim is partially paid or denied, you have 30 days from the decision to file an appeal. A second appeal is available if the first is denied, again within 30 days.13United States Postal Service. File a Claim The 30-day appeal window is easy to miss if you’re not watching for the decision letter, and that’s where many people lose money they could have recovered.
