Explaining the Meaning of Numbers on a Golf Ball
Do you know what the numbers on a golf ball mean? Do you know whether they even mean anything at all? The numbers that are most commonly stamped by manufacturers onto golf balls do not really having a meaning, but they certainly do have a purpose. We'll explain that, plus what other numbers golfers might see on a ball, and what those numbers mean.
Most Common Number: ID Numbers
Every golf ball manufactured today for sale to the golfing public carries, in the largest type that appears on the ball, the brand name of the manufacturer. Titleist balls, for example, all have "Titleist" emblazoned on them. Makes sense.And almost every ball made today also has, most-commonly right below that brand name, a number. That number is usually a 1, 2, 3 or 4. But, less commonly, it will be a 5, 6, 7, 8 or 9.
What do those numbers under the brand name mean? As noted above, these numbers don't really have a meaning (they don't impart any information about the golf ball itself), but they do have a purpose. And that purpose is identification.
Single-digit numbers that appear just below (or, sometimes, just above or adjacent to) the big-type brand name on a golf ball are there for ID purposes. They are there to help golfers keep straight who is playing which ball.
Imagine you and a friend are both playing Titleist Pro V1 balls. Your balls wind up next to each other in the fairway. Which is which? If you chose a ball with a "1" stamped on it, while your friend teed off with a ball stamped "2," you'll know which is which.
That's what those numbers are for. And that's why golfers should, on the first tee, tell each other what brand, model and number ball they are playing. "I'm playing a Srixon Model X number 3." (All golfers should add a personal identifying mark to their golf balls, too.)
These ID numbers are most often a 1, 2, 3 or 4. In a box of a dozen golf balls, the balls are typically held in four "sleeves" (smaller boxes), with three balls per sleeve. The balls inside a single sleeve will all have the same number, but each sleeve within a box of a dozen usually carries different numbered-balls (e.g., in a box of a dozen, one sleeve will have balls numbered 1, the next sleeve balls numbered 2, then 3, then 4).
Some brands also sell boxes of a dozen balls with sleeves carrying balls numbered 5, 6, 7 and 8. And some brands also offer balls with the number 9. But 1, 2, 3 and 4 are by far the most-common, because they are the standard, the base models.
Beginning mostly in the 2000s, some manufacturers also began offering custom options for the ID numbers on golf balls. The numbers offered usually range from 1 through 99.
It's not unusual for a golfer to develop a personal preference for a specific number on his or her balls. Most golfers will play whatever ball they pull from the bag, regardless of its ID number. But some golfers develop an attachment to, say, the number 1, or balls marked with a 3; other golfers might develop a superstition and avoid certain numbers.
But to recap: The single-digit number, usually a 1, 2, 3 or 4, that is the most-prominent number on a golf ball and appears with the brand name, is there to help golfers identify their balls after each stroke.
Numbers That Are Part of the Ball's Name/Brand
At the time of writing, one could find, among others, the Titleist Pro V1, TaylorMade TP5 and Bridgestone e5 golf balls on pro shop shelves. Those numbers don't really mean anything, they are just part of the name chosen by the manufacturer. (In some cases a numeral that is part of a golf ball's name might refer to the iteration of the model.)Occasionally a numeral included in a ball's name does have a specific meaning. The Dunlop 65 ball, for example — one of the most-famous and long-running balls in golf in the middle part of the 20th century — was named in honor of the second-round 65 (then a tournament record) Henry Cotton scored en route to winning the 1934 British Open.
But most numbers that appear as part of the golf ball brand stamped onto a ball do not carry a specific meaning and are just part of the ball's chosen name.
Other Numbers That Might Appear on a Golf Ball
Once upon a time it was also common to see one or two other numbers on golf balls, one of them a two-digit number, the other a three-digit number. Both numbers, if they appeared (and if they appear today) were usually stamped in smaller type.
- Two-digit numbers on golf balls referred to the ball's compression rating. It was very common in the 1970s to early 2000s to see the compression rating stamped on golf balls. The number usually ranged from 70 to 110, and told golfers how soft or firm a golf ball would feel at impact. (Compression rating carries other performance indicators, too, but softness/firmness is how most golfers of the past era interpreted a rating number on a golf ball.)
It is not common today for compression rating (which comes in a much-wider ranger than it once did) to be stamped on a golf ball.
- Three-digit numbers on a golf ball are most-likely to be a dimple count — the actual number of dimples that are in the cover the ball. The number of dimples typically ranges from the low 300s into the high 400s. It was once common for ballmakers to stamp this number onto their golf balls. But dimple count, like compression rating, doesn't appear nearly as much as it once did.
