The number of stamps needed to send a letter from Texas to Washington depends on the weight and type of mail. As of my last update, a standard first-class letter (up to 1 ounce) requires one Forever stamp. For heavier letters or additional services, you may need more stamps or different postage. It's best to check with the USPS for the most current rates and requirements.
