While there is not a limitation to the quantity of numbers that you can have, there is a limitation to the quantity of numbers that you can add to your account in your dashboard. The exact amount you can add is based on how many lines in your plan you have selected.
If you find that you need more numbers than you are able to add yourself, please contact us at support@one40.com so we can manually add them for you.
