How do I update my TCAD address?

You will need to contact the Address Management Services office to first verify your correct address. Once verified, the Address Management Services team will notify the Travis Central Appraisal District (TCAD) of the correct Situs Address. Although TCAD might update their internal records upon notification, their website might not reflect this change for several months.

Also, while we send a courtesy notification to TCAD, this does not ensure that your records have been updated in their system. If you need verification that their records have been updated, you will need to contact TCAD directly.

Please also note the Situs Address is not the same as your Mailing Address. To update your TCAD Mailing Address, you will need to contact TCAD directly to request this. The Address Management Services office can only verify and notify TCAD of the Situs Address.


How do I find out my ZIP Code and Mail To city?

The City of Austin's Address Management Services office does not maintain ZIP Codes. Only the US Postal Service can accurately verify your ZIP Code and Mail To city. You can use the ZIP Code lookup tool on the US Postal Service website, or contact them directly at 800-275-8777.


I need to find out what city my property is located in. How do I do this?

You can verify your property’s jurisdiction by visiting the City of Austin’s Development Web Map and following the steps below:

To find an address:

  1. Make sure the Search Type dropdown states “Address”. The button is located at the top next to the City of Austin seal.
  2. Enter the address in the text box next to the “Address” button and click GO
  3. It will show you a list of address matches. It looks for a match to an address point first, and then on a street range if a point doesn’t exist. We recommend picking the Address whenever possible. Simply select the one you want in the list. It will take you to that location.

To verify the jurisdiction of the address:

  1. Choose Identify under the Map Tools dropdown.
  2. Click on the address in the map.
  3. A pop-up box with the Identify Results will show up. If necessary, click the Features dropdown arrow within the Identify Results box and choose (Jurisdiction).


You may also contact the Address Management Services team with questions concerning jurisdiction verification. While we can determine the city and county your address is located in, we are unable to provide City/County permitting information. 


When an address is changed, who does the Address Management Services office notify and who is the property owner responsible for notifying?

Address changes are published on the Address Management Services website. Agencies that reference the address change database to update their records include:

  • Emergency service providers (Police, Fire, EMS)
  • United States Postal Service (1-800-275-8777)
  • Travis Central Appraisal District (512-834-9317)
  • Williamson County Appraisal District (512-930-3787)
  • Travis County Voter Registration (512-854-4454)
  • Williamson County Voter Registration (512-943-1629)
  • Time Warner Cable (512-485-5555)
  • AT&T (1-800-464-7928)
  • Texas Gas Service (1-800-700-2443)
  • Austin Energy (512-494-9400)


The Post Office will continue to deliver mail sent to your former address for at least one year. This period is normally sufficient to change printed matter, notify correspondents and correct telephone listings. The Post Office requests you not fill out a Change of Address form from the Post Office. The Post Office requests you update the address numbers on your mailbox to your assigned 9-1-1 address by the effective date provided on your address change notification.

The property owner will need to contact the entities directly to update their billing/mailing address. Although the above entities have access to the address change database, this does not ensure that your records have been updated in their system. If you need verification that their records have been updated, you will need to contact them directly.

Are there recommendations for posting my address?

Yes. Please clearly post addresses so they are visible from the street. Consider that emergency responders may be searching for an address at night, or in smoke, fog or heavy rain. Darkness and bad weather greatly reduce the visibility of addresses. Any addressing conflicts that may be obvious in daylight can be confusing in the dark or in bad weather. Your address is assigned to make it possible for the emergency service providers to locate your address as quickly as possible.  You can help them by posting your assigned address using reflective numbers.

How do I stop Avast Antivirus from blocking your website and/or webforms?

If Avast blocks any website, you can add an exception from the Avast blacklist to access the blocked website.

Avast provides a whitelist, a list of entities considered trustworthy. You can add file paths, URLs, and specific applications to this list, and use Avast to exclude them from being scanned. To except URLs from Avast protection, follow these steps.

Step 1: Open Avast on your computer and go to the Avast dashboard.

Step 2: Click Menu, and click the Settings tab. Click the Exceptions tab under the General tab

Step 3: Under this tab, click ADD EXCEPTION and a new window will appear. Type the URL that you want to add to your whitelist.

Step 4: Click ADD EXCEPTION to save the URL.

The website and/or web form you want to access should now be available.
