Claim CoStar Group

Prove you run costargroup.com and the profile becomes yours to control: a free workspace with CoStar Group as your company, the public findings brought in as drafts, and a say over every item on the public page. Your claim never opens anyone else's workspace.

Step 1 of 2

Create a free account with your @costargroup.com email

We send a 6-digit code to that address. Entering it proves you run costargroup.com.

No address at costargroup.com? Create the account with any email and prove the domain with a DNS record or a tag on your website instead.
