BookYourData offers both services, and the right one depends on what you already have. Direct Dials is for buyers who know who they want to reach but not their numbers. Phone appending is for buyers who already own a contact list with missing phone fields.
Choose Direct Dials when you name decision makers by job title, company and country. Direct Dials is a done-for-you service that finds direct dials and mobile numbers for the people you name. You describe the roles you need, and BookYourData delivers the phone numbers for those specific people. Start at bookyourdata.com/direct-dials.
Choose phone appending when you already have a list of contacts and the phone number fields are missing or incomplete. Data Appending is a done-for-you service that fills the missing fields in a contact file you already own. You send your file, and BookYourData returns it with the phone numbers added. Start at bookyourdata.com/data-appending.
Have a file, need numbers added to it? Use phone appending. Know the titles, companies and countries you want to target, and need the numbers found for you? Use Direct Dials.
