USPS “Notice Left (No Authorized Recipient Available)”: What It Means and How to Get Your Item

Short answer

“Notice Left (No Authorized Recipient Available)” means USPS tried to deliver an item that needed a signature, no one was available to sign, and the carrier left a notice. USPS’s scan-event reference describes it as “The item could not be delivered because a signature was required.” USPS’s tracking help page adds that “There will be no automatic second delivery attempt.” You can schedule a redelivery, pick the item up at the Post Office listed on the notice, or ask USPS to return it to the sender. If no one claims it by the return date shown in tracking, it goes back to the sender.

Key takeaways

  • USPS’s scan-event reference lists the status as event 56 and describes it as “The item could not be delivered because a signature was required.”
  • USPS’s tracking help page says the carrier left a PS Form 3849 Redelivery Notice and that “There will be no automatic second delivery attempt.”
  • You have three options: schedule a redelivery, pick the item up at the Post Office on the notice, where you or an authorized agent must show valid photo ID, or ask USPS to return it to the sender.
  • For Certified Mail, Registered Mail, Signature Confirmation, Adult Signature Required, and USPS Tracking, a USPS help page lists 15 days held after the first delivery attempt. For Priority Mail Express it lists 5 days. For accountable mail such as Certified and Registered, Adult Signature, and Priority Mail Express, the sender can set fewer days, so the return date in your tracking is the one to go by.
  • A closed business is not a Notice Left. USPS uses a separate status, “Redelivery Scheduled for Next Business Day,” which tells the customer “No action needed.” The reference notes that this event is now combined with No Access on the scanning device, so a closed business may also show as “No Access to Delivery Location,” which also needs no action.
  • Some of the most important certified mail comes from the IRS. The IRS manual says a notice of deficiency returned “unclaimed” or “refused” is “generally not considered undeliverable,” and the 90-day period to petition the Tax Court (150 days for a notice addressed to a person outside the United States) runs from the date the notice was mailed.

Before you start

  • Copy the tracking number and the return date shown in tracking. The steps below depend on how much time is left.
  • Find the notice the carrier left. It shows the Post Office where the item is held and a barcode you can use to schedule redelivery.

Who this is for

  • Anyone whose tracking shows Notice Left (No Authorized Recipient Available) and who wants the item before it is returned.
  • Business owners who receive certified or signature-required mail, including IRS and state notices, at a business address.

What “Notice Left (No Authorized Recipient Available)” means

The status means the carrier tried to deliver an item that needed a signature and no one was available to sign for it. USPS’s April 2026 scan-event reference on PostalPro lists it as event code 56 and describes it as “The item could not be delivered because a signature was required.”

The customer message in that reference reads: “We attempted to deliver your item at TIME on DATE in CITY, STATE, ZIPCODE and a notice was left because an authorized recipient was not available. You may arrange redelivery by using the Schedule a Redelivery feature on this page or may pick up the item at the Post Office indicated on the notice beginning NEXTDAY. If this item is unclaimed by RETURN DATE then it will be returned to sender.”

USPS’s tracking help page explains it the same way: “The package requires a signature and no one was available to sign for it. The carrier left a PS Form 3849 Redelivery Notice. There will be no automatic second delivery attempt.” That last sentence is the part to act on. No second delivery attempt will happen on its own. A final reminder notice may follow, and if no one acts, the item goes back to the sender.

The Notice Left statuses compared

Notice Left has a parent event and three subtypes in the USPS reference. A closed business is not one of them. It is tracked separately, and it does not need anything from you.

Tracking statusUSPS descriptionWhat it asks of you
Notice Left (event 02)“Delivery was attempted. The notice shows options for pickup or re-delivery.”Schedule redelivery or pick up at the Post Office.
Notice Left (Receptacle Full/Item Oversized), event 54“The item could not be placed in the delivery receptacle, either because the receptacle was full or because the item was too large to fit.”Schedule redelivery or pick up at the Post Office.
Notice Left (No Secure Location Available), event 55“There was no location deemed safe to deliver the item and there was no endorsement to 'leave if no response'”Schedule redelivery or pick up at the Post Office.
Notice Left (No Authorized Recipient Available), event 56“The item could not be delivered because a signature was required”Schedule redelivery for a day someone can sign, or pick up at the Post Office with photo ID.
Redelivery Scheduled for Next Business Day, event 51“The item cannot be delivered because the business is closed. On the scanning device, this event is now combined with No Access.”Nothing. USPS tells the customer “We will redeliver on the next business day. No action needed.”

Source: USPS PostalPro, PTR Event Descriptions (April 2026), read October 4, 2026. The last column is our summary, not USPS wording. Because event 51 is now combined with No Access on the scanning device, a closed business may also show as “No Access to Delivery Location,” which the same reference says is redelivered on the next delivery day with no action needed.

Your three options

USPS’s tracking help page lists three options for this status.

  1. 1Schedule a redelivery. USPS says to schedule it “for a date when someone will be at home to sign for it,” using the tracking number or the barcode on the notice. The USPS redelivery page says redeliveries “can be scheduled online 24 hours a day, 7 days a week,” and that for same-day redelivery the request must be in “by 2 AM CST Monday-Saturday.” The same page first asks you to check whether redelivery is available for your address.
  2. 2Pick it up at the Post Office. Go to the Post Office listed on the notice. USPS says “An authorized agent can pick it up for you. You must show valid photo ID.” The customer message says pickup is available beginning the next day.
  3. 3Have it returned to the sender. USPS says you can “Request the package to be returned to sender using the Redelivery application.”

How long USPS holds the item

The hold period depends on the mail service. A USPS help page on notice and return dates says “Carriers will leave two notices (regardless of whether or not a customer schedules a redelivery): first and final.” It lists the second notice at 5 days after the first notice for Certified Mail, Registered Mail, Signature Confirmation, Adult Signature Required, and USPS Tracking, with 15 days held in total after the first delivery attempt. For Priority Mail Express, it lists the second notice at 3 days and 5 days held in total. It adds that “Unless otherwise noted, the return date is in calendar days, not Postal business days.”

The Domestic Mail Manual (DMM) sets the rule for Priority Mail Express and accountable mail such as Certified and Registered Mail: “If the piece is not called for or redelivery is not requested, the piece is returned to the sender after 15 days (5 days for Priority Mail Express, 10 days for COD), unless the sender specifies fewer days on the piece.” So for those services the sender can shorten the window. The return date in your tracking is the one to go by.

If the time runs out, tracking changes to “Unclaimed/Being Returned to Sender.” The USPS reference describes it as “A notice and reminder were left but no one claimed the item before the DMM stipulated hold period (typically 15 to 30 days) was over.” That range is the reference’s general wording. The sender then sees the endorsement Unclaimed, which the DMM defines as “Addressee abandoned or failed to call for mail.” Our guide to USPS return to sender reasons covers that endorsement and the others.

Who can sign at a business address

DMM 508.1.4.1 sets the general rule: “Unless otherwise directed, an addressee’s mail may be delivered to an employee, to a competent member of the addressee’s family, or to any person authorized to represent the addressee.” For an organization, DMM 508.1.5.1 says “All mail addressed to a governmental or nongovernmental organization or to an individual by name or title at the address of the organization is delivered to the organization.”

Some services narrow who can sign. Adult Signature Required “provides delivery to a person who is 21 years of age or older.” For mail marked Restricted Delivery, DMM 508.1.1.8 says postal employees must deliver it “only to the addressee or person authorized in writing as the addressee’s agent.” An addressee who gets restricted delivery mail regularly can name an agent on PS Form 3801, the Standing Delivery Order, or by a letter to the Postmaster. DMM 508.1.1.8 says the authorization must include the notation “this authorization is extended to include restricted delivery (or Adult Signature Restricted Delivery) mail.” If no standing order or letter is on file, the addressee can also name an agent on the back of the PS Form 3849 notice and sign it.

If your business gets signature-required mail at an office, the practical step is to know who at that address is allowed to sign for your company and to make sure someone is there during delivery hours. If no one is, the item waits at the Post Office for one of the options above.

Why it matters for IRS and other certified mail

Some of the most important mail a business gets arrives by certified mail. The Internal Revenue Code says the IRS “is authorized to send notice of such deficiency to the taxpayer by certified mail or registered mail,” and that a notice of deficiency “if mailed to the taxpayer at his last known address, shall be sufficient.” In commentary on a 1999 proposed rule, the IRS described a notice mailed to the last known address as sufficient “even if it is not received by the taxpayer.”

The IRS’s own manual addresses unclaimed notices directly: “A notice returned by the United States postal service stamped "unclaimed" or "refused" is generally not considered undeliverable.” For a notice of deficiency, the deadline to respond does not wait for you to pick the letter up. Under section 6213(a), the taxpayer may petition the Tax Court within 90 days, or 150 days if the notice is addressed to a person outside the United States, “after the notice of deficiency authorized in section 6212 is mailed.”

That is the case for one type of IRS notice. Other IRS letters, state agencies, and courts follow their own rules. For lawsuits, the federal rules let a plaintiff serve an individual by following state law, as one of two routes, so check the rule that applies to the specific document before you assume anything about a missed notice.

Two habits help. Keep the address the IRS has for your business current, which you do with Form 8822-B. And when tracking shows Notice Left on something from a government agency, pick it up rather than waiting for a second attempt that, for this status, will not come.

When the address is a business mailing address

Signature-required mail needs a person. If you use an office, coworking space, or mail service as your business address, ask how it handles items that need a signature before you give that address to the IRS, your state, or a court. Our guide on how to receive certified mail at a virtual address covers what to ask.

Before you give an address to senders, you can look it up in our free address checker. It shows whether USPS data classifies the address as residential or commercial and whether it is flagged as a commercial mail receiving agency (CMRA). It will not tell you who signs for mail there, so that is a question for the address provider.
