Locate the constellation your star is in. This is typically included in the information you received when you registered your star. Sites like heavens-above.com will help you determine what constellations are visible where you live.
Identify recognizable stars in the constellation so you can locate your star in relation to other nearby stars. Unfortunately, most stars are very dim and can barely be seen with the naked eye. You may need to use binoculars or a telescope to locate your star.
Determine your location. You can only see some stars at certain declinations. You need to be further north to see stars with higher declinations. For example, you need to be on or south of 27 degrees latitude in order to see a star with a declination of -65 degrees.
Use a service like Sky View if you can't see the constellation where you're located. Select the "non-astronomer" interface. This is a database with pictures of all the stars in the sky. Enter the Right Ascension (RA) and Declination (DEC) for the "sky coordinates or object." Select "optical survey" and you will see a small image of the sky with the star you named in the center.
