Compile Phone Numbers Database

I already have an Excel sheet with 500 companies and the right decision-maker’s name for each. What’s missing are their direct phone numbers, and that’s where I need your help.

Your task is straight-forward: research and add an accurate, working phone number for every contact in the list, entering it in the same row in local format. I will share the spreadsheet, and you can work in Excel or upload a neatly formatted CSV—whichever keeps the data clean and ready for me to use immediately.

I will spot-check 10% of the entries for accuracy before releasing payment, so please rely on reputable sources, double-verify extensions, and avoid generic switchboard numbers whenever possible. If a direct line truly can’t be found, note that clearly in the sheet so I know it was attempted.

When you return the file, I should have:
• One local-format phone number (or a “Not Found” note) filled in for every contact
• No other columns altered

Let me know your estimated turnaround time and any questions you have about the sheet, and we can get started right away.
