Hi all,
I have a pretty thorough list of area codes and exchanges that I apply (shortcode imports) to all the system I build, but I have a site I'm doing now that needs to be locked down as to block any possible toll-fraund or toll-charge number . This is in the US.
Anyone got a good list? I've done some googling and can't seem to find what i'm looking for.
I currently have it blocked down pretty tight only 1-855 through 1-888 numbers can be dialed with a 1 prefix. I am a bit concerned about any local exchanges or area codes that are tolled or use for fraud. I am already blocking 976 exchange and areacode, 211, 311, 411, 511, 611, 711, 811 exchanges as well.
Anything i'm missing?
