When your MLS is activated, your MLS username will be your state issued license number with a "B" in front of it. For example, SL5551212 would be B5551212. You may access the MLS at www.swflamls.com. Supra eKey's can be issued to licensed Realtors. Supra charges a one-time $50 activation fee to new users and a monthly fee of $19 per month billed on the first of each month to a credit card on file.
