Services offered by Thailand Post
Thailand Post offers a range of services at very reasonable prices. This includes a track and trace service(EMS) which is similar to registered post and requires the person receiving the article to sign for it. This is both domestic and international mail.
You can even “post” large items like a motorcycle using your local post office. Thailand Post offices sell stamps and all manner of packaging to ensure your item arrives safely. You can actually pack your parcel in the Post Office after you buy packaging. Thailand Post also provide money transfer facilities and pay at post, which is a facility to pay bills.
