Why Include a Thru Address: Key Advantages
Adding a thru address to your letter does more than just play a bureaucratic game; it streamlines the entire delivery chain. A thru address tells the postal service exactly where to hand the package or how to route it efficiently. If the mail begins in a city with a high volume of outgoing mail, the thru address can guide it past intermediate sorting centers and reduce interception errors.
The benefits include:
- Speed: Mail typically moves faster when the correct thru address is provided.
- Accuracy: Reduces misdelivery rates by providing a stable routing reference.
- Cost savings: Some postal carriers charge extra per keystroke; a thru address can offset that by simplifying the system’s job.
Here’s a quick comparison table showing typical delivery times with and without thru addresses in a dense urban hub (data sourced from the U.S. Postal Service survey, 2023):
| Delivery Method | Median Days to Reach Destination |
|---|---|
| Standard Letter Without Thru Address | 4–5 days |
| Standard Letter With Thru Address | 2–3 days |
These numbers illustrate why a thru address is not optional—it’s an efficiency lever under any heavy mailing regime.
