Abstract: An extendable and resilient mailbox is implemented in which the mailbox can revertibly extend outward to improve accessibility to the mailbox during heavy snowfall. The extendable mailbox is also configured with break-away action which enables the mailbox to laterally move and resiliently revert (or “break away”) to a base position. For example, when a snow plow inadvertently crashes into the extended mailbox, the mailbox will laterally move in the direction of the encounter to reduce the chances of or prevent the mailbox's destruction. Once the snow plow has passed or at least is no longer clashing with the mailbox, the extendable mailbox reverts back to its base position in which it is aligned with the mailbox post.
