Filing with the Post Office

Once an NPO has been established within its state and has sent its IRS filings, it can petition the US Postal Service (USPS) for the right to use nonprofit-rate mailing. Very often, the Postal Service will allow an organization to begin using the lower rate postage for its materials even before the tax-exempt status paperwork has been given approval by the IRS. For nonprofits that have a business ID number registered to a nonprofit corporation as well as an EIN, it is a good idea to check with the USPS for access to these special rates.
