It's actually the number for Lamar University Academic Partnerships. It is a legitimate University, however, if you do not want receive calls from colleges, don't fill out general online forms for a college search, especially do not give your phone number. If you are interested, call the place, or email admissions. These forms that help you "find" colleges don't do what they claim. They send your information to any and all applicable colleges.
I keep getting hang-up calls from this number. I know it's Lamar. I sent them a Facebook message with a screenshot of a hang-up call at 8:00 A.M. on Saturday morning. They are denying it's their number. Shocker. They said, "All of our phone numbers at the University start with 409.880.XXXX." I'll bet those aren't the only numbers. Nice try, Lamar. You have people calling us on your behalf, and you know it.
It's Lamar University. They call quite often but just checking on how things are going. A bit excessive, but it's rare a college cares enough to even call.
