Dimensions summary
This listing uses a single pricing dimension called Product Access (Units). You buy it under a contract that grants access to the ZIP Code Time Zones data set. There are no separate tiers, instance sizes, or usage add-ons to choose from. Your purchase gives you access to the data, which maps each US ZIP Code to its IANA time zone and covers the United States and its territories. The data is updated monthly and delivered in multiple file formats.
Top-of-mind questions for buyers
One unit of Product Access grants you access to the ZIP Code Time Zones data set under your contract. This gives you the mapping of each US ZIP Code to its IANA time zone, covering the United States and its territories. There are no per-record or per-user charges layered on top.
Access includes three data points per record: the 5-digit ZIP Code, the official IANA time zone name, and whether the area observes Daylight Saving Time. You receive the data in four formats: CSV, JSON, XML, and SQLite. The current record count is 38,932.
The data set is updated monthly, so your access covers current mappings over your contract term. It excludes APO, DPO, FPO, and unique single-entity ZIP codes because those are non-geographic. All other US ZIP codes and territories are covered.
