Houston Zip Code - Delaware
The US ZIP Code basic format consists of five decimal numerical digits assigned to the Houston City. An extended ZIP+4 code, introduced in the 1980s, includes the five digits of the Houston ZIP code, a hyphen, and four more digits that determine a more specific location within a given ZIP code in Houston, Delaware.
The Houston Zip Code is 19954.
If you want to send a mail to Houston City, you should use the 19954 Zip Code.
In 1983, the U.S. Postal Service introduced an expanded Houston ZIP code system that it called ZIP+4, often called "plus-four codes", "add-on codes", or "add ons". A ZIP+4 code uses the basic 19954 Zip code plus four additional digits to identify a geographic segment within the five-digit delivery area, such as a Houston city block, a group of apartments, an individual high-volume receiver of mail or any other unit that could use an extra identifier to aid in efficient mail sorting and delivery in Delaware.
