Complete the application form available from the UK ISBN Agency and the Nielsen BookData database form; obtain both from the same agency. Include the required information, like page samples.
Check the application carefully for legibility, accuracy and completeness. Poorly completed forms slow the application process.
Enclose the appropriate payment by Visa, MasterCard, check or Maestro. Enclose an additional fee for expedited handling. Current fees are located on the Agency's website.
Indicate which services you are ordering. They include publisher registration, assignment of an ISBN prefix and lists of ISBNs. ISBNs come in blocks of 10, 100 and 1000. Additional blocks are available for an additional fee.
Mail, fax or email the completed application to the agency.
Await an email from the agency containing the ISBNs that have been assigned to you. If you prefer to have your ISBNs mailed to you, enclose the extra fee in your application.
