Structure Zip Code Notification For Free

Your zip code acts, not unlike a pin code, to verify the card and billing details you have entered. If you are receiving an error message, please contact the bank that issued the card you are using to complete payment. Once you speak to them please verify their information on file for that card.

This is because ZIP code boundaries are based on mail routes and delivery points rather than geographic factors. The U.S. Post Office Department, predecessor to USPS, developed a zoning address system in 1943 as a way to make sorting and delivery of mail easier.

Sometimes its causes by localities having a typo in a street address or a recent change in zipcode. One common cause is having a P.O. box as a billing address with a previous provider which confuses the system when they try to port in as they want to have a physical address.

If you are shipping packages from a ZIP code different than your return address, you can set the Mailed From ZIP to the ZIP code that you are shipping from. This will ensure that mail is properly routed through the USPS. To set the ZIP code, go to Shipping > Carriers and click Settings on the Endicia connection.

Mail handlers will put the correct zip code on the package so it will be delivered to the recipient.

The correct format for a numeric ZIP+4 code is five digits, a hyphen, and four digits. The first five digits represent the 5-digit ZIP Code; the sixth and seventh digits (the first two after the hyphen) identify an area known as a sector; the eighth and ninth digits identify a smaller area known as a segment.

Due to an increase in population or to the improve postal operations, the US Postal Service® will occasionally add a new ZIP Code or change ZIP Code boundaries.
