Direct Mailing CASS and NCOA

NCOA and CASS Certification

NCOA is a database maintained by the U.S. Postal Service of all individuals and companies who completed a Change of Address form in the previous four years.

Over 40 million Americans change their address each year. Outdated address information or address information that was not entered correctly, or is not in the correct USPS format are a major cause of undeliverable-as-addressed (UAA) mail.

This can lead to wasted resources and missed revenue when your mailings are not being received by your intended audience.

An NCOA update can reduce undeliverable and duplicate mail pieces by identifying incorrect addresses and correcting them prior to mailing.

National Change of Address (NCOALink) is a secure dataset of approximately 160 million permanent change-of-address (COA) records consisting of the names and addresses of individuals, families and businesses who have filed a change-of-address with the USPS”. [USPS] The USPS offers licenses for Interface Developers and Interface Distributors and all NCOALink interfaces are USPS certified. There are six licenses available including Full Service Providers (48 months) and Limited Service Providers (18 months). To obtain bulk mail rates, NCOALink is required, as it reduces the number of “undeliverable-as-addressed” mailpieces, saving money and reducing the USPS’s processing of this type of mail.

The Coding Accuracy Support System (CASS)

CASS certification is offered by the USPS to all mailers, service bureaus, and software vendors that would like to evaluate the quality of their address-matching software and improve the accuracy of their ZIP+4, carrier route, and five-digit coding. When choosing a vendor to process your mail, you want to make sure they are CASS certified. CASS Certification must be renewed annually with the USPS to meet current CASS Certification cycle requirements.

For more information on CASS Certification, visit the address management section of the USPS web site. CASS software will correct and standardize addresses. It will also add missing address information, such as ZIP codes, cities, and states to ensure the address is complete. Any mailing claimed at an automation rate must be produced from address lists properly matched and coded with CASS-certified address matching methods.

New York City

I have worked many years in New York City in the IT and gaming industry. At first I have worked as an IT consultant for diverse french luxury companies. I was leading projects onsite and managing a team of developers based in Philippines. It provided me great experience in managing team overseas. Afterward I worked for a well-known french real estate agency focusing on short-term rental until the arrival of the mega-monster company airBnb who took over the entire industry such as a tsunami. Thereafter, I spent many years working in the gaming industry where I developed and pioneer innovative social gaming technics with Facebook at their headquarter Menlo Park

Git list of conflicted files

git diff --name-only --diff-filter=U

GIT pull coworker branch

git remote add coworker git://path/to/coworkers/repo.git
git fetch coworker
git checkout --track coworker/foo

This will setup a local branch foo, tracking the remote branch coworker/foo. So when your co-worker has made some changes, you can easily pull them:

git checkout foo
git pull

Upgrading from 3.3.2 to Symfony 4.1

Use symfony profiler great help for upgrade


Update to the New Major Version via Composer

Once your code is deprecation free, you can update the Symfony library via Composer by modifying your composer.json file:

    "...": "...",

    "require": {
        "symfony/symfony": "^4.1",
    "...": "..."

Next, use Composer to download new versions of the libraries:

 composer update symfony/symfony

Dependency Errors

If you get a dependency error, it may simply mean that you need to upgrade other Symfony dependencies too. In that case, try the following command:

 composer update "symfony/*" --with-all-dependencies

This updates symfony/symfony and all packages that it depends on, which will include several other packages. By using tight version constraints in composer.json, you can control what versions each library upgrades to.
