Here is the step by step procedure to turn on this feature-

1. Log into your Gmail inbox.
2. Go to Settings -> Labs and scroll down a bit to locate the “Location in Signature” feature.
3. Check the Enable radio button to enable this feature and click on save changes.

4.  Now go to Settings -> General and go to the signature settings. Check Append your location

That’s it. Now your signature will always contain your current location. As this feature uses your IP address, guess you must have understood how exactly this feature works. It tracks the location of your IP and appends the Same location as your “location signature” and hence, as said earlier, your localization may depart slightly.

That said, see to it that you do not share your location with someone you may not trust, beware!
