Is there a limit for data.com records in salesforce?

Hi laveena,

Yes, there is a limit based on the license you owned.

From Setup, in the Quick Find box, enter Users and then select Prospector Users. In the Data.com Users section, find your name and see what your monthly limit is and how many records you’ve already added or exported during the month. Your administrator sets the monthly allowance, which expires at the end of each month, regardless of whether you’ve met your limit.
