Coding Accuracy Support System (CASS)

CASS is a user journey certified by United States Postal Service® in accordance with CASS Cycle O standards. The search type is meant to be used for address correction, verification and standardization. It enables users to cleanse, verify, and standardize their addresses, both in real-time and batch mode. CASS user journey is designed to overcome a significant degree of variation, fix misspellings and erroneous information, fill in omitted components and normalize incorrect formatting.

USPS suggest a standardized 5 line address format for CASS processing:

  • Address line 1 contains Building/firm name.
  • Address line 2 contains Urbanisation (only for Puerto Rico).
  • Address lines 3 and 4 must contain delivery line information.
  • Address line 5 must contain city, state, and ZIP code.

We recommend following the same structure for your address input forms.

Methods

Passive verification

  1. Enter a full address.
    • POST /address/validate/cass/v1: A fully formatted address will be returned if a verified match to a single deliverable address was made.

Recommended implementations

There are two ways that this search type can be implemented into your solution. If an accurate match could not be found, the integrator can choose whether to return the address as it was entered by the user.

The CASS search type may be used with no user interaction required after an initial search has been submitted. This allows an integrator to hide the fact that there is any address management occurring within an application from the user.

This implementation of using the Cass search type means that addresses that are entered will be simply verified as being correct (Verified match) or not verified as being correct (Interaction required or None).

  1. The user types the address into separate fields.
  2. The user then triggers the validation process.
  3. The address entered will either be returned verified, not verified or interaction required.

The recommended workflow is:

The relevant address and enrichment components can be stored in your database if required.

The CASS search type may be used with minimal interaction required after an initial search has been submitted. This does not require the use of suggestions, but may require a single confirmation by the user if the service is not highly confident in the match.

This method of using the CASS engine means that addresses that are entered will either be:

  • Verified as being correct
  • Verified as being correct after user confirmation
  • Not verified as being correct
  1. The user types the address into separate fields.
  2. The user then triggers the validation process.
  3. The address will then either be:
    • A verified match. The matched address will be returned to the user.
    • More interaction required from the user to confirm the address is correct.
    • If address is not confirmed correct, the original entered address is presented as unverified.

The relevant address and enrichment components can be stored in your database if required.

Methods

The typical search process for CASS is as follows:

  1. Initial search: call the DoCassSearch action which returns a SearchResult object that will contain a FormattedAddress object, as well as VerifyLevel.
  2. The integrator may simply check that the VerifyLevel is high enough before using the returned address.

Recommended integrations

There are two ways that the CASS engine can be used within an address capture environment:

Passive validation - no user interaction

The CASS search type may be used with no user interaction required after an initial search has been submitted.

This implementation of using the CASS search type means that addresses that are entered will be simply verified as being correct (Verified match) or not verified as being correct (Interaction required or None).

  1. The user types the address into separate fields.
  2. The user then triggers the validation process.
  3. The address entered will either be returned verified, not verified or interaction required.

Interactive validation - minimal user interaction

The CASS search type may be used with minimal interaction required after an initial search has been submitted. This does not require the use of suggestions, but may require a single confirmation by the user if the service is not highly confident in the match.

This method of using the CASS engine means that addresses that are entered will either be:

  • Verified as being correct
  • Verified as being correct after user confirmation
  • Not verified as being correct
  1. The user types the address into separate fields.
  2. The user then triggers the validation process.
  3. The address will then either be:
    • A verified match. The matched address will be returned to the user.
    • More interaction required from the user to confirm the address is correct.
    • If address is not confirmed correct, the original entered address is presented as unverified.

In this CASS search, the full address is used in the search. Providing the user enters all the information correctly and information exists in the dataset, VerifyLevel=Verified is returned. Let's use "Gails Limo Service, 607 E Blanco Rd, Unit 831, Boerne TX 78006" as an example address. The address format of the generated request must conform to USPS defined format. The format can be found in the default official CASS layout CASSOfficialFormat in the qawserve.ini file and is also explained above.

As this example is no Puerto Rican address, address line 2 will be empty. You can see that we supplied a space for address line 2, you can also leave it blank as well. Furthermore, USPS suggest to use an all capitals format for CASS processing.

In this CASS search, the full address is used in the search. Providing the user enters all the information correctly, but the primary number is invalid, VerifyLevel=InterractionRequired is returned. Let's use "910 N Manhattan Ave,Manhattan KS 66502-7039" as an example address. The address format of the generated request must conform to USPS defined format. The format can be found in the default official CASS layout CASSOfficialFormat in the qawserve.ini file and is also explained above.

As this example has no building or firm name, is not Puerto Rican address, and also has no secondary information, address lines 1, 2, and 4 will be empty. You can see that we supplied a space for address line 4, you can also leave it blank as well as shown for address lines 1 and 2. Furthermore, USPS suggest to use an all capitals format for CASS processing.
