Purpose: Identifies requests by the metro code (Designated Market Area - DMA) from which the request was issued.
Should I use Metro Code or DMA Code?
Both of these match conditions provide the same capability. However, we recommend the use of the Metro Code match condition to identify requests by DMA.
Key information:
-
Specify a metro code as an integer value.
Request DMA codes from Nielsen.
- Specify multiple metro codes by delimiting each one with a single space.
- Metro codes are only applicable for traffic from the United States.
- Wildcards are not supported when specifying a metro code.
- Certain requests may not return a valid metro code. A question mark (i.e., ?) will match requests for which a valid metro code could not be determined.
-
The Result option determines when this condition will be met.
- Match: This condition is satisfied when the request originates from one of the specified metro codes.
- Does Not Match: This condition is satisfied when the request does not originate from one of the specified metro codes.
