U.S. Mail

The District Post Office (DPO) processes mail for delivery to the US Postal Service. Schools and district offices and departments submit outgoing US mail to the DPO in special sacks and by doing so, take advantage of the large-volume discounted postage rates the district receives from the USPS.

The DPO also processes US mail for external (non-HISD) clients. By sending your US mail through the DPO, you reduce your postage rates through the volume discounts offered by the USPS to large-volume business mailers.

To take advantage of these savings and receive your US mail sacks, call the District Post Office - Main Office at 713-676-9400.
