The Address Validation API is a smart solution to resolve inaccurate contact details and enable faster delivery of packages with precision. This API appropriately formats the input recipient address information that closely resembles a valid address and returns a real-world address that is likely to be the one intended.
The API also provides annotations about deficiencies in the input address or changes that were made to the input to arrive at that real-world address. You can use this API to validate and resolve the recipient address information before you ship a package.
Note: Do not use this API to determine the deliverability of an address. FedEx does not offer delivery service to every valid address. FedEx does not deliver to P.O. Boxes except via FedEx Ground® Economy (Formerly known as FedEx SmartPost®).
Address Validation API Details
This API allows to validate and correct recipient address information before shipping a package. Accurate addresses on the shipping label will help eliminate delivery delays and additional address correction fees (due to malformed addresses).
- Address resolution results vary by country/territory.
- The entered address in the request is compared with the reference data in the FedEx database and the matched address is returned.
Address Validation API Functionalities
- Provides street level address matches.
- Receives monthly updates to its address database.
- Distinguishes between business and residential addresses if an exact match is found.
- Does not currently verify suite or apartment numbers.
Address Validation API Capabilities
- Completes the incomplete recipient addresses. In some cases, Address Validation API will be able to add missing information, depending on the verification of the provided information against reference data. Address Validation API cannot add missing secondary information (i.e., apartment or suite) at this time.
- Receives monthly updates to its address database.
- Corrects invalid recipient addresses. For example, correction of an incorrect postal code to agree with the remainder of the input.
- Determine whether an address is business or residential to increase the accuracy of courtesy rate quotes. Applies to U.S. and Canada addresses only.
- Confirm the validity and completeness of addresses in many countries in these regions: U.S., Canada, Latin America, Europe, the Middle East and Asia Pacific. You are now able to validate domestic and international address information before shipping a package, eliminating unnecessary delivery delays and additional service fees.

How Address Validation API Works
Use this endpoint to validate and resolve input addresses and returns real-world addresses. The address details are provided and validated in order to resolve an address. An address is stated as resolved when the input address matches the known reference data.
The required input information associated with this request is:
- Street Lines
- City (Optional)
- State or Province Code (Optional)
- Postal Code (Optional)
- Country Code
Note: State code or city name is enough when customer shipping to a country which does not have a postal code.
The Address Validation API returns a real-world address by performing the following operations on the input address:
- As the first step, the API attempts to normalize the input address. This can include replacing common roadway identifiers such as street and parkway with their standard abbreviations such as ST and PKWY, as well as reordering components of the address. If an input address cannot be normalized, the resolved addresses returned will be the input address. Non-address values are discarded.
- In the second step, the API attempts to standardize the normalized address by finding a possible or actual address that is likely the one intended by the user. If that standardization fails, the resolved addresses returned will be the normalized form of the input address. Refer to the elements returned to help determine the problems with the address submitted.
- Certain elements of that normalized address will also be returned. If standardization does succeed, the resolved addresses returned will be that real-world address. In this case, various additional elements of the standardized address and information on how it was derived from the normalized address is also returned.
Address Validation API Return Values
If the address returned includes the following values for the below attributes, then the address is valid:
- Address State is Standardized
- Attributes of Resolved address are True
- Delivery Point Valid (DPV) is True
- Interpolated Address is False
If these are not listed, then use the additional attributes to determine the possible problems with the address values.
For more information on Address Attributes, see Address Attributes.
If the output returned customer message is INTERPOLATED.STREET.ADDRESS, then there is a chance that the address is not valid. For more information on customer message code, refer to the element description of customer message.
Urbanization (Puerto Rico only): This descriptor, commonly used in urban areas of Puerto Rico, is an important part of the address format as it describes the location of a given street. In Puerto Rico, repeated street names and address number ranges can be found within the same postal code. These streets can have the same house number ranges. In these cases, the urbanization name is needed to correctly identify the location of a particular address.
Example: Sr Pedro Rivera Urb Hermosillo 123 Calle 1 Bayamon, PR 00961-1212.
Address Validation API returns annotations with every address validated and returned. The annotations give you information on the deficiencies if any and the changes made to the input address to arrive at that real-world address.
The Address Validation API uses reference data to determine the classification of a given address. The classification for a functional address is calculated independently of the validation address process and is based on feedback by operational personnel, with commercial data sources used for confirmation only.
The Address Validation API has only four possible classifications for addresses: unknown, business, residential and mixed. All addresses begin with an 'unknown' classification and stay that way until address validation business rules determine that their classifications should change. A location only gets a 'mixed' classification if it is a multi-tenant-based address and contains both business and residential units.
Note: FedEx Express service provides an additional address line (address line 3) for recipient addresses. This additional address information provides more complete and accurate location details improving your chances of getting accurate address.
The real-world addresses are classified as follows:
A business address is an address that is used to designate your principal place of business. It is where your business is supposedly operating from, but that may not always be the case.
A business address is the official location of a company's premises. It could be anything from someone's home address right up to a multi-million-dollar campus, such as those big tech companies favor and everything in between.
A residential delivery charge will apply to shipments within the U.S. made to a home or private residence, including locations where a business is operated from a home. Use FedEx Home Delivery for residential delivery via FedEx Ground in 1 business day, based on distance to the destination.
- Residents of multiple-unit dwellings, such as:
- Apartment buildings
- College dormitories
- A residence where products are sold and/or distributed
Tips for Using the Address Validation API
