TH

The two-character ISO 3166 country code for THAILAND.

TH

1. ISO 3166-1 alpha-2 code for the Kingdom of Thailand. This is the code used in international transactions to and from Thai bank accounts.

2. ISO 3166-2 geocode for Thailand. This is used as an international standard for shipping to Thailand. Each Thai province has its own numeric code with the prefix "TH." For example, the code for the Province of Bangkok is ISO 3166-2:TH-10. The exception to this is the Province of Pattaya, which has a geocode of ISO 3166-2:TH-S.
