What is Address Validation? Does Postmen support it?

Postmen API does not support address validation for now as we are still focusing on integrating more carriers for label printing and rates calculation. In this post, I am going to tell you different options for address validation in the market that you can choose from.

What is address validation?

To be precise, address validation is also called address verification, address suggestion or address correction. In general, it refers to Street-level address validation which returns single or multiple address suggestions when you provide a street-level address. Some services will also return if it is a residential or commercial address.

Carriers / Service Provider	Street Level Validation	Countries
USPS	✓	USA
UPS	✓	USA
FedEx	✓	USA + 44 countries
Google Places API	✓	All

Why address validation API?

Decrease chances of delivery delays or undelivered shipments due to an incorrect address entry.
Reduce additional charge of address correction by the carrier.

USPS Address validation API

USPS offers Address Information API - which covers both street-level address validation and zip/city/state lookup. USPS' street-level Address validation API is called address standardisation, which returns you back a corrected address when you provide a single street level address.

XML Request

<AddressValidateRequest USERID="XXXXX">
  <Address ID="0">  
    <FirmName />   
    <Address1 />   
    <Address2>205 bagwell ave</Address2>   
    <City>nutter fort</City>   
    <State>wv</State>   
    <Zip5></Zip5>   
    <Zip4></Zip4> 
  </Address>      
</AddressValidateRequest>

XML Response

<AddressValidateResponse>

    <State>WV</State>
    <Zip5>26301</Zip5>
    <Zip4>4322</Zip4>
  </Address>
</AddressValidateResponse>

UPS Address validation API

UPS offers both street-level address validation and zip/city/state lookup for USA addresses similar to USPS. Unlike USPS, street-level validation of UPS return multiple address suggestions instead of just one. The documentation naming for UPS could be confusing, but do refer to Address Validation Street Level API.

Operation Name	Level
Address Validation	`zip/city/state Lookup`
Address Validation Street Level	`Street Level Validation`

Alternative - Google Places API

Google Places API - Place Autocomplete is a paid API that suggests addresses of countries that Google Map supports. The request is less strict compared to UPS, FedEx or USPS which you can simply pass an input value to return a possible list of addresses.

In the request, you can specify the address type you want Google to return in the response:

geocode instructs the Place Autocomplete service to return only geocoding results, rather than business results. Generally, you use this request to disambiguate results where the location specified may be indeterminate.
address instructs the Place Autocomplete service to return only geocoding results with a precise address. Generally, you use this request when you know the user will be looking for a fully specified address.
establishment instructs the Place Autocomplete service to return only business results

Why doesnt Postmen support Address Validation?

Just not the right timing. And if you need one, simply use USPS/UPS for USA ones, and FedEx/Google one for international addresses. Do note that Google places APIs is a paid service.
