The "mailbox rule" is a fundamental principle of contract law stating that an acceptance of an offer is legally effective the moment it is dispatched (dropped in the mail), provided it is properly addressed and has sufficient postage.
The Mailbox Rule governs when an offer is accepted, therefore forming the contract. The rule states that the offer is accepted as soon as the offeree places their acceptance in the mailbox, so long as it is addressed properly and has sufficient postage.
Yes, a postal carrier can refuse to deliver mail if a mailbox is blocked by vehicles, trash cans, or snow, as they require safe and clear access, generally about 15 feet on each side of the box. While carriers are supposed to attempt delivery for temporary obstacles, they can stop delivery if the blockage is a recurring issue.
Currently, under Internal Revenue Code (Code) section 7502 (a/k/a the "mailbox rule"), a return or payment is deemed to be delivered to the IRS on the postmark date (so long as there is adequate postage and the item is properly addressed).
The USPS is removing or sealing some traditional blue collection boxes primarily to combat mail theft and protect postal workers. Criminals have increasingly targeted these boxes—often using stolen master keys to access them and steal checks or sensitive mail. In areas with high crime rates or low usage, the boxes are being removed entirely or upgraded to high-security models with narrow slots instead of pull-down handles.
Placing a dryer sheet in your mailbox to ward off unwanted insects is a widely shared tip, but it's not a reliable way to keep pests out. While strong scents can sometimes discourage insects, they don't address what attracts them in the first place.
The United States Postal Service implemented several key operational, pricing, and policy updates, which include the following major changes:
The USPS will not forward standard marketing mail, packages sent via other carriers (like FedEx or UPS), or mail that the sender explicitly marks "Do Not Forward".
The IRS almost exclusively initiates contact by mail delivered through the U.S. Postal Service. If the agency is looking for you regarding an audit, unpaid taxes, or identity verification, you will receive a formal written notice or letter.
You own the physical mailbox on your property, not the federal government. You are responsible for its purchase, installation, and maintenance. However, once installed and ready for use, the mailbox comes under federal jurisdiction and is strictly protected by law for the delivery of U.S. mail.
It is a federal crime to destroy, hide, open, or embezzle mail that is not intended for you. The official crime is obstruction of correspondence, which is a felony. If you're found guilty of this crime, you could face up to five years in prison and some hefty fines.
Yes, placement matters. The U.S. Postal Service (USPS) requires mailboxes to be placed on the right-hand side of the road in the carrier’s line of travel. For most driveways, this means the mailbox should sit on the far right side as you pull out of your driveway facing the street.
To request door delivery, you need to submit PS Form 1528, Request For Exception To Current/Proposed Delivery Mode Due To Physical Hardship and the required documentation, including a statement from a doctor. The doctor's statement should indicate you are unable to collect your mail from a curb or centralized mailbox.
The mailbox rule states that contract acceptance is effective upon dispatch, not receipt. However, this default rule does not apply in several common scenarios. It is typically superseded by specific exceptions, particularly regarding offers, specific contract types, and contradictory offer terms.
The concept of the 12-second rule refers to the fact that the average person spends 12 seconds reading an email. More recent data shows that people are spending more time reading emails, but the overall conclusions remain the same: people skim their emails.
Customers must remove obstructions, including vehicles, trash cans, and snow, that impede safe and efficient delivery.
You might find a dryer sheet in your mailbox because your mail carrier placed it there to deter stinging insects like wasps, hornets, and yellowjackets from building nests inside. The strong aromatic fragrance of the sheet acts as an effective, non-toxic repellent that keeps pests out and protects the carrier from painful stings when reaching inside.
As of May 22, 2026, the average annual pay for a Senior Mail Carrier in the United States is $80,287 a year.
Who has the authority to check your mail in California? According to the U.S. Postal Inspection Service website, first-class letters and packages are protected under the Fourth Amendment. They cannot be opened without a search warrant, the website states.
The IRS audits returns that show anomalies, unusual claims, or discrepancies when compared to statistical norms for your income and occupation. The agency uses automated screening and document-matching programs to find returns that are most likely to have errors.
Federal authorities may open an investigation based on tips, complaints, ongoing surveillance, or referrals from other agencies. The investigation's goal is to determine whether there's enough evidence to pursue charges under federal law.
Top 10 Signs You're Being Investigated for a Crime in California
If the owner has not updated their address, you could continue to receive unwanted mail for years: coupons, newsletters, catalogs, political flyers, charity solicitations, etc. To resolve the situation: Mark “RETURN TO SENDER.” This instructs the mail carrier to return the mail to whoever sent it.
Mail getting returned to sender is usually caused by an incorrect/incomplete address, an expired forwarding order, or the mail carrier not recognizing the recipient's name at that location.
The USPS generally cannot redirect or forward marketing mail (junk mail), packages shipped via certain services (unless you pay additional postage for Media Mail/USPS Retail Ground), or mail explicitly endorsed by the sender as "Do Not Forward". Additionally, mail sent through private couriers like FedEx or UPS cannot be redirected by the Post Office.
