I would like to know if there is any standard placeholder text for each & every content in a business card? The content may include
There's no standard, but the important consideration is to make sure you're not using a value of an entity that actually exists. There's an entire Wikipedia article on placeholder names. It covers all kinds of things, including company/organizations and physical addresses.
You should use one of the reserved example second level domain names as specified by RFC 2606.
- Reserved Example Second Level Domain Names
The Internet Assigned Numbers Authority (IANA) also currently has the following second level domain names reserved which can be used as examples.
This will prevent you from using a domain or e-mail address that actually exists. That document also lists TLDs that are reserved if you'd like to use something a little more interesting, such as "email@example.com".
Some countries have fictitious telephone numbers. For the US: not every number prefixed with 555 is safe to use, so be careful there!
Not all numbers that begin with 555 are fictional—for example, 555-1212 is one of the standard numbers for directory assistance throughout the United States and Canada. In fact, only 555-0100 through 555-0199 are now specifically reserved for fictional use; the other numbers have been reserved for actual assignment, with the notable exception of the 800 area code where only 800-555-0199 is reserved.[source]
I have never heard of any standard placeholder text but you can use something like this
Name: John Smith
Owner (I wouldn't use the words job/position, that is implied)
It was brought to my attention that yourcompany.com is a registered domain name which should not be used in any example mockup. It is best to use a reserved domain name: example.com, which is mentioned in JohnB's answer.
Phone: 123.456.7891 or I have used 555.555.555 or however you want to format the phone number.
I don't have any sources to back up if this is "standard" placeholder text.
