Saturation vs. High Density Rates

If your list is in Walk Sequence order below is an explanation of when you will get Saturation rates vs. High Density rates:

You need to mail to 90% of residences in a carrier route, or 75% of the total active addresses in the route in order to get Saturation rates. Otherwise you get High Density rates if you have 125 or more in a route. So if you are mailing to an entire route and still not getting Saturation rates, this could mean that our CRRT counts are older than the data source of where the Walk Sequence list was purchased from. Our carrier routes are updated every two months with the DVD bi-monthly updates and carrier route counts may change in between your updates. Make sure you’ve installed the latest DVD update to ensure you are validating against the latest USPS database files available from AccuZIP.

I Just wanted to let you know we are in the Postal Fort Worth Texas Division and I received a call from someone in their office today wanting to ask me some questions. He asked if I understood about the changes with the move update starting for this month, then he asked me what software we were using. I explained to him that we have been using AccuZIP Software for the last 20 years and I thought you were the #1 in the United States. I told him that you were the only software displayed in the Postal Section of the Smithsonian Institute. He asked me if I had to manually change the updated addresses and I told him no that the Software did it for us and I could print a report showing the old address and the new address. He told me out of 32,000 names that were updated only 3 were wrong and he just wanted to call me to see what Software we were using. Thanks for such good software and support from your company over the past 20 years.
