The "Upload New List" wizard lets you create a list from your own spreadsheet file of company information. To do this, you need a CSV-formatted file containing the following columns of information: Company Name, City, State and Country. Alternatively, you may upload a list that contains just the UK Registration Number field, OR AVID (also known as a Key ID). You don't need to give the columns headers in your spreadsheet as you do this when you upload it. You can upload a list of up to 1,000 records. Any additional data that is not used for matching will be included when the list is exported. To upload a list, click the 'My Lists' option at the top of the page. Here you will find the 'Upload a New List' button located on the left-hand side. Select this and follow the instructions on the screen to find your file and open it. When you open a file, you are asked to enter a list name and map the columns in your file. When you click 'Begin Import', the list will be created and placed under "My Lists".
