You can buy your Texas hunting license, along with any additional endorsements ("stamps"), or tags, at any one of more than 1,700 license retailers across the state. Check the Texas Parks & Wildlife Dept. (TPWD) website to find a retailer near you. You can also purchase your license at a TPWD regional or field office. If you have a credit or debit card, you can order your hunting license online. Your online receipt will act as a temporary license, however if your activity requires tags, you'll have to wait for them to arrive in the mail.
