The Bhutanese postal system is reliable, you can send mails from hotels and post offices and no special procedures are necessary. If you mail cards or letters from the Thimphu post office, you can buy exotic Bhutan postage stamps from the philatelic bureau and use them on your letters and postcards. Bhutan Post offers outgoing EMS [expedited mail service], which is a reliable and fast international mail delivery facility that is cheaper than courier services. It also has a LUM [local urgent mail] service for delivery within Bhutan. DHL is the only international courier to operate from Bhutan.
Most of the country’s major towns have both domestic and international direct dial facilities. Nearly all hotels and some PCOs have facilities to send and receive faxes. Bhutan has its own Internet and email services.
