Preferred MARRS numbers are now available to claim for the 2015 season.  We have a new registration system for Club Racing this year - we are now using (MSR).  You will need an account in MSR to claim your number.  Click here to set up an account in MSR.

2/13/15 - MARRS preferred car numbers are being assigned now to those who have qualified from last year to automatically keep their number.
  The remaining numbers will be in a pool for you to claim on a first-come, first-served basis.  The 2015 MARRS preferred numbers will be available for everyone to claim on Wednesday, February 18th.  A registration link for numbers will be sent by email to drivers, and also posted here.

A change to be aware of for 2015 is; the new online registration system for Club Racing will be (MSR).

  • If you already have an active account with MSR, you do not need to do anything extra – you can claim a number with the new system when they become available and it will go into your existing MSR account.  (You may be prompted to add the Washington DC Region SCCA as one of your clubs.) 
  • If you do not yet have an account with MSR, you must set up a new account there.  When the link is set up and sent out to claim a number on 02/18 - it will be for MSR only, so you need an account.
Click here to set up an account in MSR.  If you need assistance or have any issues logging into or using MSR, please call Katie or Ann at 415-462-5603 x9 (M-F 9-6 Pacific time) or send an email to   They will be happy to help!

PLEASE NOTE:  The “Late Date” for registration has also changed for 2015, so you need to be aware that if you do not register by 12:01 am on the Tuesday prior to each event – in addition to the extra “late registration” fee of $50 - your reserved number will be released for that event and anyone can use it.  It will revert back to your account for any future 2015 MARRS home events.
