Variables for consistancy

Hi, I'm sure this is on here somewhere, I just can't find it.

Can I setup Website Wide variables for consistence, ease and not make mistakes? Mainly 'email', 'phone', 'address' etc so I can:

Set Variables

{{location.email}} = email@email.com

{{location.address}} = business address

Use Variables:

Email: {{location.email}}

Address : {{location.address}}
