Alter Zip Code Resolution For Free

You Can't Change the Shipping Address on a USPS Label Once you purchase the label, the address information is what it is, and there's no getting around that. However, if you made a mistake on it, you do have the option to intercept it and reroute it to a new address.

As of 1963, zip codes' numbers are determined by a few factors: the area, the regional postal facility and the local zone. The first number of the five-digit code signifies the region which the address is located in, a number that grows from the east coast to the west.

The normal time for regular mail to reach its ZIP to ZIP destination is about three to five days, even when sent to a different state. State-to-state mail delivery times do vary on occasion due to factors like the destination being in a rural area, and operational/functional emergencies.

Normally, if the address falls within the zone of your local postal service, the automation machines at the plants will sort the mail piece to the correct zip code location.

A United States postal code, for example, might be either five digits or five digits followed a hyphen (dash) and another four digits (12345-1234). If you are validating US postal codes, allow for both conditions. The following rule validates a field that can be five digits, five digits + dash + 4 digits, or blank.

Remember, a zipcode is an alias for a city+state delivery area. Thus, if you have the correct zip code but wrong city it should still be corrected and get delivered.

Usually what happens is a carrier or post master from the office where the package is sent will correct the zip code by looking at the address and even reach out to that particular post office to ensure the package is delivered to the correct address.

It will probably go first to the ZIP code on the package. Proper handling should be for that post office to mark out the wrong ZIP. Then the machinery will look up the right number and send it to the right place. It may be returned to you as undeliverable.
