Mail delivery time from zip code to zip code calculator

A very specific and useful request!

There are a few online tools and APIs that can help you estimate the mail delivery time from one zip code to another. Here are a few options:

1. USPS (United States Postal Service) API: The USPS offers a free API that provides estimated delivery times and costs for mail and packages. You can use their API to calculate delivery times between two zip codes. You'll need to register for a free account and obtain an API key to use this service.
2. ZipCodeAPI: This is a paid API that provides a range of zip code-related data, including estimated delivery times. You can use their API to calculate delivery times between two zip codes. They offer a free trial, and then it's $49/month for a basic plan.
3. ZipCodeWorld: This website offers a free zip code lookup tool that includes estimated delivery times. You can enter two zip codes and get an estimate of the delivery time. They also offer a paid API for more advanced use cases.
4. Google Maps API: While not specifically designed for mail delivery, the Google Maps API can be used to estimate delivery times between two locations. You can use their Directions API to get an estimate of the driving distance and time between two zip codes, which can be a good proxy for mail delivery time.

Here's an example of how you might use the USPS API to calculate delivery times:

USPS API Example

• Register for a free account and obtain an API key
• Use the following API endpoint: https://secure.shippingapis.com/ShippingAPI.dll?API=CityStateLookup&XML=<CityStateLookupRequest USERID="YOUR_API_KEY"><ZipCode ID="0"><Zip5>10001</Zip5><Zip4></Zip4></ZipCode></CityStateLookupRequest>
• Replace 10001 with the zip code you want to start from
• Use the CityStateLookup API to get the city and state associated with the zip code
• Use the ZipCodeLookup API to get the estimated delivery time from the starting zip code to the destination zip code

For example, if you want to calculate the delivery time from zip code 10001 to zip code 90210, you would use the following API call:

https://secure.shippingapis.com/ShippingAPI.dll?API=ZipCodeLookup&XML=<ZipCodeLookupRequest USERID="YOUR_API_KEY"><ZipFrom ID="0"><Zip5>10001</Zip5><Zip4></Zip4></ZipFrom><ZipTo ID="1"><Zip5>90210</Zip5><Zip4></Zip4></ZipTo></ZipCodeLookupRequest>

The API response would include an estimated delivery time, which you can use to plan your mail delivery.

Keep in mind that these APIs and tools are subject to change, and the estimated delivery times may not always be accurate. It's always a good idea to check with the USPS or other shipping carriers for the most up-to-date information.
