Zip Code Lists

What Zip Code Lists Are

A zip code list is a named collection of US zip codes
used for geographic targeting. Lists are managed on the
Geographical Filters page and referenced by buyer and offer filters
and by filter sets, so one upload can drive many routing
decisions.

Creating and Populating a List

A list has a name, an optional description, and one or
more uploaded CSV files containing the zip codes. The CSV
layout is flexible: zip codes can appear in any column.
During import each value is normalized to a five-digit US
zip code (shorter numeric values are zero-padded), blanks
and duplicates are removed, and the list shows a count
per file. You can upload additional files later; the list
is the combined, de-duplicated set of all its files.

Using Lists in Filters

In the Geographical Filters section, select zip code lists under "Zip
Codes" and choose "Matches Any Listed Item" to include
matching calls or "Does Not Match Any Item" to exclude
them. A call matches when its geographic data falls
inside any of the selected lists. Filter sets can
reference zip code lists the same way.

Updates Propagate Automatically

When you add or remove zip codes, every filter that
references the list is refreshed automatically a short
time later, so live routing follows your latest upload
without re-editing each buyer or offer.
