There are 2 major ways that mail delivery can be comprised with an incorrect address. Here we will talk about the first way. This has to do with the named individual not residing at the street address which is on the envelope or postcard. At least 10% of the population moves each year and a bad address never gets better. So after two years, you can expect 20% of the addresses on your list to be dead weight if you have not corrected them.

Fortunately, the post office has a way of fixing these addresses. It is called “NCOA” or National Change of Address. This is the most common way for a mailer to make address corrections BEFORE the mail goes out. The “BEFORE” is a critical piece because it means that almost none of your mail will be thrown out or delayed in delivery.

The post office creates and maintains a list of every delivery point (mailbox) in the United States. When someone moves they fill out a card and leave it at the post office that lists their old and new address. That information is eventually transmitted, usually within a couple of weeks, to the master address list with hundreds of millions of United States addresses. If someone skips town or dies, the letter carrier is charged with updating that information and alerting his station manager of this. Eventually the change will occur.

When a mailing comes in, the customer list is sent electronically. The mailing service then compares this list via computer to the most updated postal list as provided by the software owned by the mailing service. The software vendor then finds the bad addresses and replaces them with the good addresses. The mailing service should send a report back to its customer listing the old and new addresses so that the customer can change their database.

Here’s how not updating an address list can hurt you. One mailing service found 525 bad addresses in its last 2 mailings.. If each piece was worth 40¢ in postage and printing, that amounts to more than $200 in waste. If these were fund raising appeals and 5% would have made a gift of $25. Then, the customer lost another $656 in lost revenue.

Anyway you look at it, on the front end or on the back end, bad addresses will hurt you.

List Hygiene – Part 2

There is a second part to list hygiene which often gets overlooked. These are the addresses that are often ignored by mail owners but the importance is significant nevertheless.
Step back a moment and think about the address where you live. Let’s say you live at “123 Washington Ave S”. If a mailing list with your name on it contains the address “123 Wsh Ave”, is this enough for the post office to deliver it? Maybe not. What if your address on the list is “12300000 Washington Ave”? Would the computer program at the post office be smart enough to know where you live?

These addresses are known as “Non CASS” addresses and every database contains them. They are little thorns, and sometimes big thorns, in the efficient delivery of mail. Unfortunately 80% of these types of addresses never get delivered.

You pay a higher postage rate for these to go out AND the chances of having them delivered are low. Bottom line is you are wasting money.

What is the solution?

You will have to do a little more research to get the address right, either calling the addressee to verify the number on their address, double checking the street spelling or correcting the zip code. The time will be well spent. Remember – a bad address never gets better so you will repeat this error and waste money every time you mail that list.

If your mail service does not routinely send you these non-CASS addresses, ask for them.

Fortunately, there is a do-itself-yourself way to fix these. It is the postal service website at Click on the tab that says “Find a Zip Code”.

Type in the address you have researched and changed. See if it goes through without an error. If it is OK, you will see a message – “Here’s the full address, using standard abbreviations and formatting”, followed by the correct address as it should appear in your database and the way the postal service wants to see it. If it fails, you will see an error message and you can try again.

Address Corrections and fixing NON-CASS records are important elements for insuring that your mailing will be as successful as possible.

Failure to pay attention to these details can minimize results and disappoint expectations.
