Frequently Asked Questions: For Sellers

Question: How do we qualify to sell DID’s on DIDX?
Answer: Be a CLEC or own a network of your own. As of March 25, 2008, all new sellers must add at least 50 international DIDs or at least 500 USA/UK DID before your DIDs will become available for sale on the DIDX network. (The minimum may be raised at a later date.)

Question: When do I get paid?
Answer: Once your offered DID is sold and 45 days are passed and at least $100 is due, we pay you. Just invoice us by clicking CONTACT US in your DIDX dashboard. If the DID did not work for more than 3 days in a week, we will not pay you for that DID, and we will not charge the customer for that currently monthly rate. All successful minutes charged will require payments in case where DIDX seller is charging per minute, not flat rate.

Enter the first and last numbers of that series against ‘Multiple Numbers’. Then insert the ‘Setup’, ‘Monthly’ and ‘Per Minute’ charges that you want to charge on the DID(s) and press the ‘Submit’ button.
