Microsoft Monetize - Postal code lists



If you are advertising in connection with any financial, insurance, education, career and employment, and/or housing services, you may not use postal codes for the purpose of personalizing advertising, segmenting, or profiling customers.

Leveraging postal codes is a powerful way for advertisers to achieve highly granular and precise, or hyperlocal, targeting. Hyperlocal targeting is a key factor in driving advertising performance. Because sellers and curators often want to increase efficiency by targeting the same set of postal codes across multiple deals, the Postal Code List feature allows users to easily reuse a predefined list of postal codes.

The Postal Code List feature enables users to:

  • create postal code lists (include or exclude) so that a list can be used across their deals.
  • enable postal code lists (include or exclude) for targeting at the deal line item level. The maximum number of postal code lists a deal line item can target is 100.


Certain legitimate ZIP or postal codes are unrecognizable or invalid within the Microsoft Advertising geography targeting system. This can happen because Digital Envoy, a Microsoft Advertising partner that handles geolocation data, can't recognize a ZIP or postal code's existence until an IP address (user) has been associated with it. Postal codes that don't exist in the system often represent obscure or otherwise small geographical zones with minimal internet activity.

Manage postal code lists

You can create a Postal Code List at the Network level. A Postal Code List may contain one or more postal codes. Postal codes can be added to multiple Postal Code Lists. However, a postal code can be added only once to a single Postal Code List.

Postal codes can be added to a list by either:

  • copying and pasting in a dialog box.
  • bulk uploading a CSV, Excel, or Text file.


  • The maximum number of postal codes allowed in a list is 100,000.
  • The maximum number of postal codes lists allowed per member is 8,000.
  • Postal code lists that have not been modified in six months and are not associated with line items that have served in the last six months are eligible to be deleted by Microsoft Advertising.
