Phone number lookup

Please enter the phone number you are querying

Please ensure that you enter the number carefully.
Incorrect entries may give you the wrong information or be rejected.
ICSTIS can help you with the following types of numbers:
  • Premium rate numbers prefixed 09 that are 11 digits in length.
  • International numbers prefixed with 00 that provide a product or service.
  • Directory Enquiry services prefixed with 118 that are 6 digits in length.
  • Mobile phone text shortcodes prefixed with 2, 6 or 8 that are 4 or 5 digits in length.
  • 0800 REVERSE services (enter 08007383773 for such services).
All other prefixes such as 087, 07 and regular local numbers (01 and 02) do not fall within the ICSTIS remit and cannot be checked via our website. We recommend that you contact your phone company in the first instance for further advice.
