Hi Saeed, > "خليج فارس" give me only 792,000 results Are you sure? I gave it a try and Google returned ~25 million results. Here is the query for reference: https://www.google.com/search?q=%22%D8%AE%D9%84%DB%8C%D8%AC+%D9%81%D8%A7%D8%B1%D8%B3%22 So based on your argument, OSM should go with "Persian Gulf". All the best, Isaac
