As of right now there are only about 1573 available NNNN.co domains out of the total possible 10,000 combinations. That means these are quickly running out and if you’re looking for something which may be worth investing in, four number .CO domains might be just that! Grab what you can while they’re still available for hand registration!
Attached below is a list of the remaining available NNNN.co domains… Enjoy!
