| Tracking not available for certain services | Thailand Post only offers tracking for specific services (EMS, Registered Mail, EMS Parcel).

Ask for a refund or re-send via a trackable service. | If you paid for a trackable service but no data appears after 5 business days, contact Thailand Post customer service. |
| Tracking stops after departure from Thailand | Updates after departure depend on the destination country's postal operator scanning and data sharing. | Use the same tracking number on the destination country's postal operator website. Allow 7-14 days for the first scan in the destination country. | If no update in destination country within 30 days of departure, contact Thailand Post to file an international inquiry. |
| Package stuck in customs in destination country | Duties or taxes may be owed, or the package has been selected for inspection. | Check for a duty notice from the destination country's postal operator or customs authority. Pay outstanding fees promptly. | If stuck for more than 15 business days with no duty demand, contact the destination country's customs office directly. |
| Long delivery time for EMS packages | EMS delivery times vary significantly by destination; remote areas, customs delays, and public holidays can add significant time. | Check the estimated delivery timeframe for your specific destination on the Thailand Post website. | If delivery exceeds the stated EMS maximum timeframe for the destination, contact Thailand Post to open a trace request. |
