Common Thailand Post Tracking Problems
Expand each issue for the cause, what to do, and when to call Thailand Post directly.
Tracking not available for certain services
Cause
Thailand Post only offers tracking for specific services (EMS, Registered Mail, EMS Parcel). Standard unregistered airmail and surface mail are not trackable.
What to do
Verify your service type. If the sender used unregistered airmail, no tracking data will be available. Ask for a refund or re-send via a trackable service.
Escalate when
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
Cause
Updates after departure depend on the destination country's postal operator scanning and data sharing.
What to do
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.
Escalate when
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
Cause
Duties or taxes may be owed, or the package has been selected for inspection.
What to do
Check for a duty notice from the destination country's postal operator or customs authority. Pay outstanding fees promptly.
Escalate when
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
Cause
EMS delivery times vary significantly by destination; remote areas, customs delays, and public holidays can add significant time.
What to do
Check the estimated delivery timeframe for your specific destination on the Thailand Post website.
Escalate when
If delivery exceeds the stated EMS maximum timeframe for the destination, contact Thailand Post to open a trace request.
