There were an instance at the beginning of this week where a duplicate MLS numbers was coming through the Regional MLS system of West Palm Beach, FL. On the surface, this doesn't seem too big of an issue but it can cause havoc on web sites that run on Regional IDX.
MLS numbers are unique numbers identifying properties from one another. Obviously, if there are two numbers exactly the same, this is going to cause an issue. Regional IDX corrected the issue on all hosted web sites and notified Regional MLS personnel of the issue.
It doesn't happen very often, just a few times a year, but it does happen. No suprise that it's happening at the beginning of the new year since most technology companies implement changes during this time.
All is well now!
