Our original AP2's and our 710 AP2's both have conforming grooves as well as our original AP1's, 710 AP1's, ZB's, ZM's, 710 CB's, 710 MB's.  All are conforming to the new USGA "groove" rule.  You can check out all the conforming clubs at: http://www.usga.org/InfoClubsDB/index.asp.    Just put in Acushnet for the manufacturer.

Can you confirm if the 710 AP2's should have a serial number on each club. i have recently bought a new set from my club pro, and the clubs don't have a serial number present.

Should I be concerned?

I wondered about this with my 2010 710 AP 1's I was told by Titleist that the serial # would appear on the 6 iron hosel only. I'm curious if you hear different?

The serial number will appear only on your 6 iron if the specs, and set configuration are standard.  If you changed the specs or the set configuration, the serial number will be on all the irons.

hi, where can I check the serial number of my MB710 irons on 6th iron? where can I type it and get the results or register them? ty

If you purchased your clubs from an authorized Titleist pro shop and the serial number shows that location, you can be assured that your clubs are authentic.  If you purchased them online from a non authorized dealer, we can only tell you what specs left with the attached serial number.  Unfortunately, just as copies of clubs can be made, they can also add serial numbers to those clubs.  One rule of thumb that does hold true is "if the price is for a new set and it is too good to be true, the deal is too good to be true".

Hi Cian,  All clubs made in the US will have 5 or 7 digits as the serial number.  Are you in the US?

Hi Cian,  I will forward your email on to our UK office and have them contact you.  We don't have serial numbers like that here in the US.

Where would you check the authenticity here in the US?  Is there a number or email to check and verify serial numbers?

thanks

Danny
