If you do not live close enough to a Thai embassy or consulate, you may visit a Thai honorary consulate-general to have your biometric data recorded for an e-passport renewal. Honorary consulate-generals are located in Colorado, Florida, Georgia, Hawaii, Louisiana, Massachusetts, Oklahoma, Oregon, Texas and Puerto Rico. The Thai Embassy (thaiembdc.us) provides location and contact information for each of these honorary consuls.
