I sent a letter via airmail at the thai post office. i payed 55 baht for an EMS, but I dont know where to check it online. The number on the slip of paper they give me is RC632531699TH. Thanks.

For 55 baht it's unlikely you sent your mail by EMS. The number you listed looks like a registered mail tracking number.

In any case, here's what you do. Remember the place where you posted the letter? Thailand Post, right? You look it up on Google to find their website. When you get to the website choose service in English (or Thai if you prefer). Select "Track and Confirm". Enter your tracking number. And Bob's your uncle.

have to add that the tracking will only work within Thailand, than you must check the others country webpage.

For US I send a lot and have experience, you can ask me.....

For UK/Ireland: just forget about it

To Japan it will arrive faster than you can find the webpage.

Not good at posting links and hiding them, so

Google the following words:

Thailand Post's Track & Trace system

and you will get the tracking website as the first hit.

But I believe EMS starts with EA, and registered start with RA.

Note, tracking works for international and domestic also.

Domestic EMS letters are also less than 40B.

Also, according to website, you can also call 1545 to check.

You are correct, the little slip has Registered checked. I have gone to Thai Post's webpage previously. There are several different links to which to search from and none of them have come up with a record. The letter is to the USA.

I will try and call the hotline now.
