How accurate is the ZIP code data?
Our data is sourced from the USPS and updated regularly. It includes all standard delivery ZIP codes, PO Box ZIP codes, and military ZIP codes for the United States and territories.
Does this work for locations outside the United States?
No — this tool covers US ZIP codes only. It does not provide information for international postal codes.
What is a ZIP+4 code?
A ZIP+4 code extends the standard 5-digit ZIP code with a 4-digit suffix that identifies a specific delivery route or block face. The 5-digit ZIP is sufficient for most mail, but ZIP+4 can help with large organizations or precise delivery.
