There are a number of possible criteria. If you just care about traffic, NNNNN.com's generate traffic, even completely random numbers. You will get low levels of traffic even with "bad" numbers so you can basically pick any numbers you want. If you want numbers that look nice or are easy to remember, pick those with repeating numbers like have been posted above. If you want to cash in on the future boom in numeric domains that spell words, get numerics that spell things. If you want your domain to have potential resale value to someone in China, choose a number with lucky Chinese numbers in it. If you want a domain with very good traffic, find a number that is a foreign postal code in a large city, or a part number, or some other significant number. The possibilities are basically endless, so if you think of any other criteria that are good please share them!
I've been reading that some Zip Code domains have sold in the high hundreds-low thousands. Are there any links to these reported sales? (i.e. Sedo or DNF or wherever.) I have yet to come across any concrete sales data. Any help would be appreciated.
I have about 2 or 3 of these now
Last time I checked a couple days ago there were about 19.5k available, so I think I'll start buying them when it reaches 10k.
The buyout could happen within a year from now
I think numeric domains are one of the best and safest investments.
One strategy I have been working on is figuring out how to acquire NNNNN.com's that may be zip codes in good areas in the future. The postal service is constantly adding new zip codes, and they usually do this in high-growth areas. Does anyone know how they go about picking what the new numbers will be?
Thanks for the link GF444 for the lucky numbers in China.
I ran some combo's tonight. Given the numbers that Michael Goldman has given only 17% of the NNNNN's are still available down from about 20% a week ago.
I ran all of the possible combinations of the Chinese lucky numbers 168,520, and 518. Only 5 of 900 combinations were available. (Gone now and rep given to GF444)
There are still some attactive combinations available. There are 1,224 NNNNN domains ending in 0. This is 12% of the total. I believe that domains ending in zero are easier to remember and would explain the 12% vs 17% of available domains. I'll list 50 of about 100 of the better NNNNN's ending in 0 that have a double number.
Edited to add that all have been registered. I'll add some more later today.
Good job everyone, and a big thank you to Michael Goldman for the scans and the lists, that is very helpful! I am trying to come up with some more lists of good numbers to post in the future.
Michael, thanks again for the scans and the posts. I don't think anyone expected numbers you posted to go that fast!
Here is a list of NNNNN.com's with repeating numbers in first and fifth position, and second and third position, that are available at the time of posting.
