Do you miss the IOC Code in your name so that others know where you're from? In Lotus Notes, this is possible through the additional 'Organization Unit' suffix under your name, say, Rolando Araya/CRC/AFSIP. This is not possible in Google without a little modification.
From Google Mail, top right you will see Settings. Click again at Accounts tab. Your default name should be your Firstname Lastname as per suggested. Click edit info next to your name. Now, add IOC code so that your name become
Firstname Lastname IOC
Next time, when you send email to another person, your name will become Firstname Lastname IOC.
