About us

11850 is Ireland’s original independent directory enquiry service. 11850 is committed to providing callers the highest levels of service, accuracy and courtesy.

Recognised as a leading innovator, 11850 was the first to introduce value added services such as free number textback.

11850 Services:

• Search for Irish business phone numbers. If you know the name of the business that you are looking for, or need to find a company via a category search, our agents will search for the number you need.
• Free number text back to your phone: When you call 11850 from a mobile phone we will text the details to you which means you can then save them to your phone for future reference.
• Live operator service: We provide a personal operator service. When you call 11850 you will be greeted with a friendly helpful customer service representative.
• Immediate connection: We can connect you to the number you require instantly. For information on 11850 pricing click here.

From the 17th August 2026, 11850 no longer offers residential phone number searches. If you call 11850 after this date for a residential phone number search that we can not fulfil, please contact our Customer Care team for a refund.
