Mailbox alert flag yellow

The classic mailbox alert flag!

In the United States, a yellow flag on a mailbox typically indicates that the mail carrier has left a notice or a package that requires the resident's attention. This flag is usually raised by the mail carrier to alert the homeowner that there is something important waiting for them.

Here are some common reasons why a mail carrier might leave a yellow flag on a mailbox:

  1. Delivery of a package: The mail carrier may have left a package or a large envelope that requires a signature upon delivery.
  2. Notice or notification: The carrier may have left a notice or a notification from a government agency, a utility company, or another organization that requires the resident's attention.
  3. Special delivery: The flag might indicate that the mail carrier has left a special delivery, such as a certified mail piece, a registered mail piece, or a package that requires a signature.
  4. Attempted delivery: In some cases, the flag might indicate that the mail carrier attempted to deliver a package or a letter but was unable to do so, and the item was left at the post office for pickup.

When you see a yellow flag on your mailbox, it's a good idea to check your mailbox as soon as possible to see what's waiting for you!
