Frequently Asked Questions
Are these real, valid ZIP codes?
These are randomly generated 5-digit numbers. While many will coincidentally match actual US Postal Service regions, some may point to unassigned areas. They are meant for format testing, not real-world mailing.
Why do some start with zero?
In the USA, ZIP codes in the Northeast (like New England) begin with zero (e.g., 02111). Our tool correctly pads the strings to ensure they maintain the strict 5-digit structure.
Do you support UK Postcodes or Canadian Postal Codes?
This specific iteration generates numeric US ZIP codes. Alphanumeric formats (like UK or Canada) are scheduled for a future update.
Can I export a large list to CSV?
Yes, by clicking "Copy Results", you can easily paste the array directly into an Excel sheet or a CSV file for database seeding.
