911 Addressing


Addressing is a multifaceted task with implications that need to be clarified. The current development and the Next Generation 911 (NG911) standards, combined with the explosive growth in the county, have created a challenging environment for addressing. San Patricio County has developed this page to simplify the addressing process and facilitate a greater understanding of the issues surrounding addressing.

The responsibilities of the San Patricio County NG911 coordinator are to assign, verify, and correct physical addresses, ensuring that all records for addresses, road names, and road signs in the databases with the local 911 Public Safety Answering Points (PSAP) and local government agencies are up-to-date.

Our office exercises this authority to provide addressing services for the county's citizens. This ongoing effort ensures that the citizens of San Patricio County receive timely and accurate services to their residences and businesses. The 911 Coordinator reverses the right to readdress/correct addresses to conform with the National Emergency Number Association (NENA), Next Generation 911 (NG911), and the State of Texas standards.

    Address Recognition and Validity

  • A physical address describes a location. Some residences or businesses maintain a physical address separate from a mailing address. However, while a physical address can be a mailing address, that has not always been the case. We recommend using your physical address as your mailing. Before requesting an address inquiry, you need to determine which addressing authority to contact. Gather all the necessary information/documents for the request (See Below). The San Patricio County NG911 Coordinator is the sole addressing authority for the County. If the area of interest is the County, you can request an inquiry. If the area is in a municipality with corporate status and a local government, you will want to contact the correct addressing agent for that municipality. The NG911 Coordinator only provides services in areas considered County unless we have a memorandum of understanding (MOU) to serve as the addressing authority for that municipality.

  • The road attributes are considered for a road inquiry. It is best practice and in the interest of all parties involved to use the road name instead of the highway number when addressing. The county would have to approve the changes to a road name. Highway numbers can and do change without input from the county. Meanwhile, county road names are generally more stable and lasting than highway numbers and less likely to create a need for a change of address.

    The NG911 standards call for naming a private road instead of stacking addresses off the main road. It generally occurs in rural residential areas when a long, skinny lot has multiple dwellings, warehouses, and buildings throughout one parcel.

    New roads created through a new development or a subdivision will have names proposed on a plat. The proposed roads are checked against existing names for duplication, overuse, and similar-sounding names. After the plat is recorded, the streets will be assigned address ranges. 

    • City roads generally originate from annexing existing county roads or commercial and residential developments. Existing roads annexed from the county could be subject to a name change, triggering a change of addresses on that road, but will likely keep the address ranges. The municipalities maintain City/Town roads.

    • A county road, usually starting with CR followed by a number, is a road in the county that is designated and maintained by the county precincts’ road and bridge. New county roads or changes require the county commissioners’ court approval.

    • A Private road, usually starting with PR followed by a number or name, is a privately owned road proposed by a property owner or for new development. New standards require that Private roads be named or numbered and follow addressing standards or requirements. A street sign is necessary on a private road, and it is the responsibility of the private road owner to procure and place the sign and maintain the road. The street sign will need to meet the county design standard.

    • Public roads in the county consist of roads maintained by the Texas Department of Transportation (TxDOT). The TxDOT highways have an associated highway number with types that include Interstate (I), United States Highway (US), State Highway (SH), State Spur (SP), Loop (LP), and Farm-to-Market (FM). Most highways have a road name, but some use the TxDOT highway number for identification.

    • Roadway signs in the United States increasingly use symbols rather than words to convey their message. Symbols provide instant communication with roadway users, overcome language barriers, and are becoming standard for traffic control devices worldwide. Familiarity with symbols on traffic signs is essential for every road user to maintain the safety and efficiency of our transportation facilities. Roadway signs are added, replaced, and maintained by the entity responsible. County signs are added, replaced, and maintained by the county precincts’ road and bridge. Meanwhile, TxDOT and the cities add, replace, and maintain their signs.

  • The County does not issue nor maintain zip codes. Zip codes are purely the responsibility of the United States Postal Service (USPS) and have no bearing on your address. While many people relate a particular zip code to a specific municipality, this can create confusion. The county has many zip codes. To find your zip code, please visit the USPS ZIP Code Lookup.
