Hi Guys, Let's get technical ;) Contact validation rules. -Name, organization, address 1-3, city, state. According to the rules , max length is 64, some Registries do indeed limit this to 64. however the EPP standard is 255. I suggest Verisign sets this to 255, as it is very likely we will encounter addresses longer than 64. I have seen addresses in India that look like this: "#46, 1st floor, 4th Main road MLA layout, behind the stadium, take the stairs right next to the cafeteria". I am not going to guess how things are organized in other parts of the world, again we are talking really old data and one can only suspect that Registrars been using the EPP standard. -Email My interpretation here is that there is no support for IDN TLD's as it must end with a 2-63 char string. There is use for brackets regarding the domain name []. Usually used to email an IP address. The regex actually prohibits this, but if you want to support this then you support both brackets or no brackets, the current specification lists them as individual optional brackets. In the user part, the following characters are supported ! # $ % & ' * + - / = ? ^ _ ` { | } ~ We actually do not support those as most registries do not support them and we ran into some issues when we did support them back in the day. That being said + is somewhat used, for example, Gmail to tag mail (user+tag@gmail.com). So all in all nothing major that cannot be adjusted in time and some of it can be ignored if decided otherwise, some not, idn email support for example. Best regards, Theo Geurts
