Pro V1 and Pro V1x Sidestamps Throughout the Years | How to Tell Which Year Your Titleist Golf Ball is From

Every two years, at an early-season PGA Tour event, a box of new Titleist golf balls emerges that is, well, markedly different than most. Safeguarded by a member of the Titleist golf ball product management team, the contents of the box are revealed to tour pro after tour pro, with a couple straightforward questions: Which one do you like best? Why?

What’s inside? About a half-dozen of the same prototype Pro V1 golf balls, but each of them with a different sidestamp design.

As every new Titleist Pro V1 represents years of rigorous R&D and player testing, every Pro V1 sidestamp represents “at least five months of development that’s running in parallel to the overall process,” according to Senior Golf Ball Product Manager Frederick Waddell. 

“Based on our player research and testing, we know that the overwhelming majority of golfers today are interacting with the sidestamp on their golf ball at some point during the round,” Waddell says. “But that’s not anything new. We’ve been incorporating alignment features into our Pro V1 models and implementing the feedback of tour players and dedicated golfers going back to 2002.”

Equipment standards dictate that every new golf ball listed on the USGA/R&A Conforming Golf Ball list feature a new, unique sidestamp that complies with specific design rules. For each new generation of Pro V1 and Pro V1x golf balls, Titleist designers create a collection of new sidestamps with varying features inspired by recent golfer feedback. Many of these are printed on golf balls at our Custom Operations facility for further internal analysis and deliberation. The semi-finalists, so to speak, are sent to Titleist Ball Plant 3 – the center of Titleist golf ball technology – where they are printed on Pro V1 and Pro V1x prototypes within the authentic manufacturing environment.

Next stop: The PGA Tour. While a winner typically emerges from the Tour players’ vote, the final decision is validated through further testing with dedicated golfers, both in-person at golf courses and through Team Titleist surveys.

“Any change we make to a Titleist golf ball has to be informed by what golfers are telling us and what they want,” Waddell says. “That is the foundation of our process and everything we do.” 

In addition, in February 2018, new alignment aid sidestamp designs were made available through the My Titleist customizer on They instantly became the most popular custom logo options selected by golfers, inspiring the new sidestamp designs for the recently-launched Titleist Tour Soft, Velocity and TruFeel golf balls, along with the new Pro V1 and Pro V1x Enhanced Alignment offerings.

Now that you have a better understanding of how we choose our sidestamps, we thought you would enjoy seeing all the different Pro V1 and Pro V1x marks throughout the years — one of the primary distinguishing marks of each model:
