Qatar’s postal service operator has warned PO box renters that they risk losing their address if they don’t pay their annual subscription fee by the end of the month.

Q-Post’s subscriptions run from Jan. 1 to Dec. 31 each year and cost QR500 for individuals and QR1,500 for businesses, according to its website. Q-Post increased its rates for a variety of services at the start of the year. Previously, a PO Box cost QR300 annually.
