Location — Where Is O Brien?
O Brien is a rural community in Haskell County in north-central Texas. The postal information associates the area with Haskell as its city-level locality. It is not a major metropolitan distribution center or an international gateway; shipments generally depend on wider regional transport networks before the final delivery leg to the community.
The surrounding area has a rural and agricultural character, making local delivery details particularly important for business consignments. A carrier may need a complete street or route address and a working recipient telephone number to distinguish a business site, residence, or other delivery point. International consignments may enter the United States through a gateway selected by the carrier or freight forwarder, then move through domestic linehaul and local delivery networks. Gateway selection and final-mile service depend on the shipment, carrier routing, and the confirmed destination address.
Address Format
How to Write the Address
- Write the recipient’s full name on the first line. Add the company name on the next line when applicable.
- Enter the complete delivery address, including the street number and street name, plus any suite, unit, building, or route details needed for delivery.
- Use the postal city and the two-letter state abbreviation on the locality line, followed by the ZIP Code: city, TX 79539. Confirm the accepted city spelling and ZIP pairing with the recipient or carrier address validator.
- For international mail, place UNITED STATES alone on the final line. Do not put the country before the domestic address lines.
- Use a legible Latin-script address and provide the recipient’s telephone number in the shipment contact fields. A phone number supplements the address; it does not replace it.

Routing and Handling Considerations
- Transport options: International express or air freight may suit urgent or compact consignments; ocean LCL or FCL can be considered for larger non-urgent freight. The domestic leg and service availability depend on the carrier and the exact delivery address.
- Gateway-to-destination handoff: International freight typically clears through a suitable United States entry gateway before domestic linehaul and final-mile delivery. The gateway should be confirmed against the carrier’s routing plan rather than assumed from the destination ZIP Code.
- Rural delivery detail: Confirm the street address, business access instructions where relevant, receiving hours, and a contact telephone number. Do not rely on the community name or ZIP Code alone as a delivery address.
- Customs documentation: Commercial goods generally require an accurate description, quantity, value, country of origin, and a consistent commercial invoice and transport document. Classification, admissibility, and any importer identification requirements depend on the goods and transaction.
- Service and charges: Rural delivery routing, address corrections, special handling, and applicable surcharges are carrier- and shipment-specific. Confirm them with the selected provider; no transit time or charge can be inferred from the ZIP Code alone.
