Bulk mail is a necessity for many companies. They want to get information out to a large group of people without spending too much. Bulk mail can also offer advantages, such as lower postage costs. While you don’t have to use IMB (Intelligent Mail Barcoding) for your mail to get the discount, many companies prefer it because they can get lower postage rates. However, the main thing to consider is CASS-certified software. If you have over 3,000 mailings per month or more, you can save money with IMB and Coding Accuracy Support Software.
Complete Codes Are Necessary
Each of the IMBs you use will hold all the information about the recipient that the mailroom sorter needs to know. However, to achieve such accuracy, you need an IMB software that uses CASS Certified Software, Delivery point, and ZIP+4 coding.
What It Is
Primarily, these options are used to verify all address information, as well as ZIP code information that you already have. It can go through your entire database, or be set up to check the address you are using right now.
Likewise, these options usually include a subscription to electronic lists of all the ZIP+4 and streets that USPS serves, which includes approximately 30 million entries and is updated every few months. Some companies will offer this service to you for a small fee. You upload or otherwise give them your list of addresses, and they run it through their programs to ensure that everything is correct.
Certification Procedures
Once you’ve used the program and everything is verified, you’ll need to have a USPS report for documentation. You aren’t required to submit the form, but the USPS may ask for it. Likewise, postage statements will have you fill out the date for when certification was completed.
