ZIP code targeting

Target the ZIP codes where you are actually growing

Anyone can hand you a list of ZIP codes. porterzip ranks yours by where your brand is catching on, then formats the list for every channel you already run.

Ranked by momentum, not by size

A big ZIP is not a growing one. We set aside the sales your ads paid for and the sales that come from a place just being big, then rank what is left. The ZIPs at the top are the ones pulling in new customers on their own.

Common questions

How are the ZIP codes ranked?

By momentum, the growth your size and ad spend cannot explain. We score every ZIP from 0 to 100 so the ones catching on rise to the top and the ones that only look hot get flagged.

Which channels can I use the list in?

Every channel you already run, from direct mail and EDDM to CTV, DOOH, social, retail siting and email. We hand you one ranked list formatted for each.

Is this built on my data or bought data?

Your own customer list. We place each customer in a ZIP and rank from there. Your contacts never leave your file.
