A postmark is a mark or stamp affixed to a piece of mail by a postal authority such as the United States Postal Service (USPS) to indicate the date and place of mailing. Postmarks serve several critical functions:
- Cancellation of Postage: By marking the stamp, a postmark serves to invalidate the same for further use.
- Evidence in Legal Disputes: Because they show the date and location of mailing, postmarks can be used as evidence in disputes requiring proof of when and where an item was sent.
- Historical and Collectible Value: Postmarks can also hold significant value for philatelists (stamp collectors) due to their historical context and rarity.
Types of Postmarks§
Hand-Stamped Postmarks§
These are manually applied postmarks, often used in smaller post offices or for special cancellations.
Machine-Stamped Postmarks§
These are automatically applied using specialized postal cancellation machines, generally used in high-volume sorting facilities.
Pictorial Postmarks§
These often commemorate a special event, location, or anniversary and are sought after by collectors.
Digital Postmarks§
A relatively new form, where the details such as date and location are digitally applied, utilized in certain advanced postal services.
Legal Considerations§
Proof of Mailing Date§
In legal contexts, a postmark can verify when a document was mailed. This is crucial for transactions requiring timely actions, such as tax returns or legal notices.
Place of Mailing§
The location indicated by a postmark can establish jurisdiction and serve as an important factor in legal disputes.
