| Postal Region / Area | General Coverage | Key Sorting or Delivery Hubs |
|---|---|---|
| Guwahati HQ area | Guwahati, Dispur, Kamrup, Kamrup Metro, Nalbari, Barpeta, and nearby routes. | Guwahati GPO and Guwahati division offices. |

This structure helps postal teams move mail from larger hubs to district offices and then to the correct local delivery point.
