Official same-month registry totals show how the .ISTANBUL namespace has changed.
No verified public .ISTANBUL sales examples with disclosed prices are currently available.
Businesses, tourism operators, cultural organisations, local services, communities, publishers, and Istanbul-focused brands may use the extension in different ways.
Present destinations, hotels, restaurants, attractions, itineraries, booking details, opening times, and location information.
Show services, qualifications, service areas, pricing, opening hours, business details, and customer contact routes.
Publish events, venues, associations, local initiatives, schedules, access information, policies, and organiser contacts.
Share Istanbul news, guides, directories, campaign portfolios, editorial policies, archives, and subscription options.

Paste multiple .ISTANBUL names, remove duplicates, review the count, and continue to bulk registration. This is useful for domain investors, brand teams, agencies, hosting providers, and resellers.
Enter one name per line, with or without .ISTANBUL. The tool removes duplicates and prepares a clean list for bulk registration.
