Do different locations of the same business have different merchant IDs?

Yes, different branches of the same business will usually have their own merchant account ID, as it helps the business with tracking and analytics. This is, however, typically more complicated for banks and their customers, as it can be confusing when more than one store exists in the same area. 

Banks need to identify the exact store within their merchant ID process. Moneyhub is one of only a few providers to do this as standard, using address data and map visualisations.
