Step 3: Tier II Core Data

• TXT2 Number: 
  A program identification number unique to the Tier II Chemical Reporting Program. TXT2 numbers are 5 or 6 digit numbers that are assigned to owners or operators of facilities.
• Customer Number (CN):
  Each customer (individual or organization) is issued a unique 11-digit identification number called a CN (e.g. CN123456789). Each customer should have only one CN based upon their name and Texas Secretary of State or Texas Comptroller of Public Accounts information as applicable.
• Regulated Entity Number (RN): 
  Each site location is issued a unique 11-digit identification number called a RN (e.g. RN123456789). Each regulated entity should have only one RN number per address or physical location.

Note: Each CN can only be affiliated with a single TXT2 number, and vice-versa.

• TXT2 Number - Contact the Tier II Chemical Reporting Program.
• CN or RN Numbers - Search the Central Registry Database.

CNs and RNs associated only with the Tier II Program are not visible in Central Registry. Only CNs and RNs associated with other programs are visible in Central Registry. Contact us for more information.

If you do not have a CN, RN, or TXT2 number, or need to claim ownership of a recently purchased facility, you will need to use STEERS to create them. For information of creating a STEERS account see our Setting Up STEERS page.

• STEERS and ePermits -online electronic reporting
• Using the Tier 2 Core Data Application
• Facilities that already have a RN can be affiliated with your CN/TXT2 using the Tier II Core Data STEERS application.
• NAICS Code Search

Follow along with the video below to create and submit Core Data applications with your STEERS account.

Once you have completed a Tier II Core Data Application you will be sent an email with a PDF Notice of Approval that will include your TXT2 Number, CN, and RN associated to or created for your application.
