Re: By the numbers.

I just realized that if I switched from (npa) nxx-xxxx to npa-nxx-xxxx in our database I could save two bytes per customer!!!

Better still, just pack it into three unsigned bytes (2^24) and format on output. Saves 11 out of your current 14 bytes... (and just turn away anybody who has those awkward foreign phone numbers).

+1

And same for IP addresses. An IP address will fit in four bytes once converted properly (but make your column 16 bytes so you can store IPv6 addresses as well).

I would, but they like to make notes with the phone number.

555-555-1234 (Bob's cell) / 455-555-1234 ext 7 / 355-555-1234 after 7pm

Actually, I was kidding when I mentioned saving disk space. The database that runs my employer's entire company is only 7MB!
