Twitter advertisers have a new tool for promoting their tweets or accounts to very specific areas: US ZIP code targeting.
It’s an addition to the existing geo-targeting options, which already include country-, state-, province- and metro-level targeting options. Postal code targeting is only available for US addresses at the moment.
There was no formal announcement of ZIP code targeting, but a Twitter spokesperson tells us that it was made available to US advertisers a few weeks ago. Social Media Today spotted it late last week.
ZIP code targeting might be attractive to small/local businesses that don’t serve or sell across an entire metro area — a service provider in Seattle, for example, that only wants to reach Twitter users in a couple specific parts of the city.
Twitter has a fairly detailed help page about geo-targeted ads for anyone wanting more details about the various local ad options.
