Can the same MLS number represent different properties at the same time?

Yes, the same MLS number could represent different properties. There are MLS organizations all over the country, but there is no standard numbering system across MLS organizations. Therefore, it is possible that two or more properties could share an MLS number. If you have permissions to view more than one MLS's data, and you search by MLS number, your search could return multiple properties.

RPR supports numeric and alpha numeric MLS Listing IDs.
