You can use your non-profit status to mail through PrintingCenterUSA’s indicia. However, mailing with your non-profit indicia would require PrintingCenterUSA to mail through your non-profit permit account. PrintingCenterUSA does not offer this service.
You must supply your CRID and Non-Profit Authorization to us upon ordering to utilize your non-profit status. To obtain your CRID, you must create an account on USPS®. To obtain your non-profit authorization through USPS, you must fill out this form and return it to the Post Office where Nonprofit Standard Mail mailings will be deposited. Once authorized, the authorization will apply nationwide. PrintingCenterUSA cannot authorize an organization.
Once you have your non-profit authorization, PrintingCenterUSA will need to be provided with the company name and CRID.
Your indicia size should be no less than ½ inch squared. Please refer to our free downloadable mailing templates here.
