Information-Based Indicia (IBI) Guidelines
Printing Internet Postage with Endicia software
Endicia software allows you to print postage directly onto your mailpieces. The United States Postal Service(R) (USPS) regulates the printing of postage using your Endicia software. Please take a few minutes to familiarize yourself with the USPS rules in this document.
The first step, before using Endicia software to print postage, is to sign up for an Endicia account, after which we will forward your information to the USPS. Your application will be processed immediately after the sign-up is complete and you may then use Endicia software to purchase and print postage.
If your address or any other information that you submitted during your online application changes, you should log in to your account and update the information in your account pages.
Purchasing USPS Postage
Just like with stamps and postage meters, your account with the USPS must be prepaid to use online postage. Endicia software lets you purchase postage in increments of $10, $25, $50, $100, $200, or $500. You can use your checking account or a credit card: American Express, Visa, MasterCard, Discover, Diners Club, or Carte Blanche.
US Postage Products
You can purchase US postage in any amount and use the postage for domestic and international mail. You can produce postcards, envelopes, self-mailers, fold-outs, newsletters, etc— if you can feed it through your printer, you can print postage on it.
Your USPS Registration is associated with a Licensing Post Office (LPO) region. The LPO region for your account is determined based on your address when you submit your application. In general, you should drop all your Internet Postage mail in a mailbox within your LPO region. You may drop mail at other LPO regions, but if you move permanently to another location, you should contact Endicia Customer Support to change your LPO to the one most frequently used.
You must deposit your mail from Endicia’s software on the day of the postage date printed on the mailpiece. DAZzle lets you postdate your mailpiece by up to 7 days. If you do not send your mail on the postage printed date, you must print a date-correction using Endicia software.
The USPS has currently approved Endicia software to print postage for certain classes of mail. The classes that are accepted and the postal rates are subject to change. Your Endicia software will automatically check the date of your software to make sure you are using the correct rates. If the rates have changed since you purchased your software, Endicia software will advise and prompt you to update your software. If you do not update your software, you may not print postage from Endicia software.
Mistakes and Refunds
If you realize you've made a mistake after you've printed postage, please refer to for the refund rules at http://www.endicia.com/refund-policy. Please make sure you do not use envelopes or label media that are too thick for your printer's paper path. If you are in doubt that a certain mailpiece will print correctly in your printer, print a test envelope or label before you print postage.
WARNING: The filing of false, fictitious or fraudulent refund requests for the return of U.S. postage is punishable under the criminal laws of the United States. 18 U.S.C. §1001
Electronic Delivery Confirmation and Signature Confirmation Acceptance
Occasionally, Endicia gets complaints that some postmasters or clerks at Post Offices are not yet aware of the Electronic Delivery Confirmation or Signature Confirmation rates. This is very rare, but if your Post Office insists that you pay the retail charges, please do the following:
- Get a receipt for any additional charges you pay upon inducting your packages.
- Send an email to firstname.lastname@example.org with the Post Office address, the name of the clerk or postmaster, and a short summary of the situation. We will follow up on your behalf.
