I currently have an internal directory of over 10million business fax numbers that are at least 1 year old. I am looking for as many new fax numbers as possible. If you are able to identify that hte number is less then 1 year old, great, if not, no problem, I will just scrub against my internal list when I recieve the records.
The site with the most accurate data is http://www.infousa411.com. They do not show the fax number by defautl when searching for a business. For example if you search for "Restorative Health Care", in San Antonio, TX, you will get name address phone etc.. but no fax. If you search for 210-734-4426, the business will show up and identify that number as the fax, and not show the phone number.
Other potential directories are [url removed, login to view] and yellowbook.com. Our main interest is the fax numbers (we do need the business name address and category too). We would like an additional field of sic code which you will convert from the category. You can get a list of sic codes here [url removed, login to view]
Please let me know me know which site you are able to get the data from, and what fields you will be able to extract. We only want records taht have a fax number.
