Thailand Post Shop
45, 8 Ratchadamri Rd, Lumphini, Pathum Wan, Bangkok 10330
For expats shipping documents abroad, this branch is the straightforward choice in Pathum Wan. EMS World's 3-to-5-day delivery to major destinations is genuinely competitive, and the Thailand Post counter staff handle customs paperwork on-site — which most private courier drop-points do not. Saturday morning hours are the quiet window worth knowing about.
Walk in at 8AM on a Monday and the branch is already open. Fluorescent strip lights run the length of a low ceiling. A row of numbered service windows lines the back wall, each with Thai signage above and a small English label below. The queue counter near the entrance dispenses paper tickets. At opening, foot traffic is light and a transaction at the counter typically takes under five minutes. By mid-morning the queue grows, so the early slot is worth taking if you have an international form to complete.\n\nThailand Post operates roughly 1,300 post offices across the country according to Wikipedia, and this Lumphini branch handles the full standard suite: domestic registered mail, EMS World international express, standard airmail and surface post, money orders, and bill payment. For international shipments, EMS World is the flagship option, covering 95 countries with documented delivery times of three to five business days to major destinations in Europe, Japan, and North America, and real-time parcel tracking around the clock. Maximum allowable weight per EMS package is 30 kilograms. The branch also handles Courier Post, Thailand Post's domestic express product, which is distinct from EMS and designed for same-day or next-business-day delivery within Thailand. Packaging materials including bubble mailers, flat-rate EMS boxes in multiple sizes (Box 3 at 35 x 45 x 20 cm up to 10 kg; Box 4 at 40 x 45 x 35 cm up to 20 kg), and adhesive tape are sold at the counter. Customs declaration forms for international parcels are filled out on-site; staff will assist with the Thai-language sections if asked.\n\nSaturday hours run 9AM to noon only. Arrive before 11AM to leave enough buffer for any form-filling.\n\nThailand Post was founded in 1883 under King Rama V, restructured as a state enterprise in 2003, and now supports 3,300 licensed postal agencies in addition to its main branches. The Ratchadamri location sits inside a mixed-use building at 45/8 Ratchadamri Road and is walkable from Ratchadamri BTS station in under five minutes, which matters when you are carrying a box.
