If you are looking for an Austin ZIP Code, the right number depends on the part of the city where you want to send mail, rent an apartment, visit a business, or find a home. Austin, Texas, has several ZIP codes, and different neighborhoods use different postal codes. For example, downtown Austin is ZIP code 78701, whereas areas of South Austin are ZIP code 78704. Other places, such as North Austin and neighbourhoods on the fringes of the city, have their own ZIP codes.
This article covers the primary Austin ZIP codes and how to determine the right code for any location. You’ll also discover why it’s important to check the entire address before sending a package or filling out an online form.
What Is the ZIP Code for Austin, Texas?
Austin does not have just one ZIP Code. The city uses multiple five-digit postal codes to help the United States Postal Service (USPS) sort and deliver mail. Many Austin ZIP codes begin with 787. However, some areas within or near Austin use other ZIP codes, depending on their location and postal boundaries.
Here are a few examples of commonly used Austin ZIP codes:
| ZIP Code | General area |
| 78701 | Downtown Austin |
| 78702 | East Austin |
| 78703 | West-central Austin |
| 78704 | South-central Austin |
| 78705 | University of Texas area |
| 78721 | East and northeast Austin |
| 78723 | Northeast Austin |
| 78745 | South Austin |
| 78748 | Far South Austin |
| 78758 | North Austin |
These descriptions provide a general guide. A ZIP code does not always match a neighborhood’s exact boundaries, and one neighborhood can sometimes extend across more than one postal area.
Austin ZIP Code List by Area
If you know which part of Austin you need, the following sections can help you narrow down the correct ZIP code.
1. Downtown Austin ZIP Code
78701 is a key ZIP code for downtown Austin. This area includes parts of the central business district, where you can find offices, hotels, apartments, restaurants, and entertainment venues. People often search for the downtown Austin ZIP code when booking accommodation, looking for office locations, or arranging deliveries to central Austin. Remember that not every address described as downtown necessarily uses the same ZIP code. Always check the complete street address.
2. East Austin ZIP Codes
East Austin has residential neighborhoods, local restaurants, small businesses, and other community spaces. Several ZIP codes cover different parts of this area.
Common ZIP codes in East Austin include:
- 78702: Parts of central and East Austin.
- 78721: Parts of East and northeast Austin.
- 78723: Parts of northeast Austin.
These areas have different boundaries, so do not choose a ZIP code based only on the words “East Austin.” Use the street address to confirm the correct postal code.
3. South Austin ZIP Codes
South Austin covers a broad area with residential communities, shopping destinations, restaurants, and access to major roads.
Some ZIP codes associated with South Austin include:
- 78704: Parts of South-central Austin.
- 78745: Parts of South Austin.
- 78748: Parts of Far South Austin.
- 78749: Parts of Southwest Austin.
If you are searching for a rental home, planning a visit, or comparing locations, these ZIP codes can help you identify the general area. They should not replace an address-level postal lookup.
4. North Austin ZIP Codes

Examples include:
- 78727: Parts of North Austin.

Some nearby communities may have ZIP codes outside the main 787 series. If you are unsure whether an address falls within Austin or a neighboring community, verify it using the official postal lookup.

The last example also shows why you should not assume that every ZIP code containing an Austin mailing address lies entirely within Austin city limits. Postal areas and city boundaries do not always match.
How to Find the Correct Austin ZIP Code
Finding a general ZIP code is easy. Finding the exact ZIP code for a house, apartment, office, or business requires a little more care.
1. Use the Official USPS ZIP Code Lookup
The safest option is the official USPS website:
You can search in two useful ways:
- By address: Enter a street address, city, and state to find its ZIP code.
- By city and state: Enter Austin, Texas, to explore ZIP codes associated with the city.
The address search is usually the better choice when you need a code for a delivery, official document, or online registration.
2. Check the Address Before Sending Mail
A small mistake in a ZIP code can cause problems with mail delivery. Before mailing a letter or shipping a package, check the street number, street name, city, state, and ZIP code together. If someone gives you only an Austin neighborhood name, ask for the complete mailing address. This is especially helpful when a neighborhood sits near a ZIP code boundary.
Why Austin ZIP Codes Matter
ZIP codes are useful for more than sending letters. They also help people organize searches and identify general locations.
1. Finding Homes and Apartments
If you plan to rent or buy a home in Austin, ZIP codes can help you narrow your search. You can compare listings in different areas and then review the exact location, travel distance, and available facilities. However, a ZIP code alone does not tell you whether a home is affordable, safe, or close to your workplace. Check the individual property and neighborhood before making a decision.
2. Planning Deliveries and Business Services
Businesses use ZIP codes to estimate delivery areas, organize customer addresses, and check whether a service covers a particular location. For example, a delivery company may ask for a ZIP code before showing shipping options. Entering the wrong code could produce an incorrect estimate or make a service appear unavailable.
3. Filling Out Online Forms
ZIP codes might help you focus your search if you want to purchase or rent a property in Austin. After comparing ads in various locations, you can examine the precise location, commute time, and amenities that are offered. However, a ZIP code alone does not tell you whether a home is affordable, safe, or close to your workplace. Check the individual property and neighborhood before making a decision..
Austin ZIP Codes and Nearby Communities
Some places close to Austin have their own postal codes. Depending on the address, you may encounter ZIP codes associated with nearby communities such as Cedar Park, Pflugerville, Round Rock, or Lakeway. These communities are part of the broader Austin metropolitan area, but they are not all within Austin city limits.
The distinction matters when you search for a property, compare local services, or arrange a delivery. A location described as being near Austin may use a different city name and ZIP code. Visit the official City of Austin sites for ZIP code maps and information on city boundaries. Instead of depending just on a map or neighbourhood description, use the USPS lookup for the most precise postal information.
Conclusion
Finding the correct Austin ZIP Code becomes much easier when you know the general area you are searching for. Downtown Austin commonly uses 78701, while areas across East, South, North, and West Austin use a range of other postal codes. Use this information to refine your search, but always validate the exact ZIP code on the official USPS website before mailing, booking a delivery, or filling out an important form. That easy procedure can help you prevent address problems and find the correct postal code with confidence.
