The Public Register Search Service (PRSS) allows you to search the register for specific and similar domain names, as well as domains that are registered to a particular registrant. The PRSS is an online tool updated daily and allows you to search using wildcards. A maximum of 21,000 results can be viewed per week. These results can be viewed in batches. You can store regular searches as favourites and a history is kept of your last 1,000 searches for quick and easy access.

The PRSS is designed to assist in the establishing or defending of intellectual property rights and other similar matters. It may be used to gather information for disputed domain name cases and for investigating and prosecuting possible offences including false identities and criminal offences. The PRSS can also be useful for academic research and Governmental functions.


The PRSS is available to everyone based in the EEA. This service is available on a contract only basis subject to the terms and conditions of the contract.


The PRSS is charged at £400+ VAT per year. If you are a Nominet registrar the fee will be charged to your credit account (as supplied on your application). Our standard 30 day credit terms and conditions will apply to our invoice. If you are not a Nominet registrar you should pay us when you receive our invoice.
